Development of a Perception System for Indoor Environments

Development of a Perception System for Indoor Environments Autonomous navigation is a well-known task in robotic research. It is associated to get the environmental information such as visual images or distance or proximity measurements from external sensors and to detect obstacles and measure the distance to objects close to the robot path[10, 35]. Most robots are equipped to distance sensors like ultrasonic, laser or infrared to be able to move through corridors and to follow walls in indoor environments. A[A1] control algorithm based on odometric sensorial information and distance measurements supplied by sonar sensors was developed to guide a mobile robot moving along a corridor or following a wall in [3]. The[A2] Probabilistic Neural Network (PNN) structure was evaluated for wall following task using ultrasound sensors in [17]. a mobile robot control law for corridor navigation and wall-following, based on sonar and odometric sensorial information is proposed. The control law allows for stable navigation avoiding actuator saturation. The posture information of the robot travelling through the corridor is estimated by using odometric and sonar sensing. The[A3] ultrasonic sensors were also used to measure and obtain the distance and orientation of a robot utilizing a Fuzzy Incremental Controller (FIC) for controlling a wall follower robot [10]. Trajectory tracking task is an especial task of wall following which is no obstacle like walls to detect. So, distance sensors like sonar or infrared could not help the robot to follow the trajectory. Control[A4] algorithms based on vision sensors have also been introduced for indoor navigation. For example, a robot utilized a vanishing point of lines extracted from the corridor structure in order to identify the heading direction. But, a complex mathematical calculation is needed to capture the vanishing point [37]. A[A5] CCD color camera was used to control the position of a robot while it navigated towards a target position [15]. The images of this camera were processed and the visual features of environment were fed through a neural network to enable a mobile robot to identify its own position. The task of orientation recognition was applied in order to follow a path in environment, too. The[A6] 3D trajectory estimation for unknown outdoor environments was investigated in [31]. This estimation was based on vision information captured by a trinocular stereo camera that is mounted on the robot. No prior map was used and the trajectory is found by tracking and detecting relative changes in the position of features extracted from images. Most techniques used complex mathematical equations and models of the operating environment to achieve the ability to move through corridors, to follow walls, to turn corners and to enter open areas of the rooms for an indoor navigation task [7]. Researchers[A7] used vision sensors to detect trajectory and to design their steering control law using the kinematic equations of motion[13, 34]. In these works which were considered in an off-road environment, the robot used both laser range finder and stereo vision. The laser was used to scan the close front ground for analyzing its roughness, and stereo vision apperceived drivable situation of far front ground. The path planning was performed using the data acquired from these sensors. Among three processes applied in outdoor navigation, including perception, planner, and motion control module, these works were focused on the decision of control laws of the robot, i.e. the longitudinal velocity, the lateral velocity, and the angles of sensor pan-tilts. The controller uses the information prepared by the planner. The characteristics of terrain like coefficient of longitudinal rolling resistance and the coefficient of lateral friction are known, and a description of trajectory space is presented according to the robots dynamic analysis. The[A8] Reinforcement Learning (RL) was applied to control a wall follower robot for learning reactive behaviors[30]. The environment is perceived in 3D using a stereo and mono vision. In this work, the images are processed to reduce the amount of relevant information and a small occupancy grid with 9 cells is created to discretize the state space. The controller utilized Q-learning technique and the action space was discrete, too. The most considerable works which have yet been done in outdoor robot navigation have constructed a grid map to determine the traversability of the terrains. The classical methods focus on a binary representation of the terrain from an obstacle occupancy point of view. Another approach is to characterize the presence of an obstacle in a grid cell by giving a continuous value. This value represents the probability distribution for occupancy of the grid cell by an obstacle. The more comprehensive methods evaluate terrain characteristics, too[9, 33]. For example, traversability is defined as a non-binary mathematical function of the slope and roughness of the terrain for each cell [18]. This traversability degree has not been interfered to robot local control directly and it has just been used in the path planner. They use some systems like GPS to find their locations and measure the distance they moved through. Kinect[A9] sensor was used to capture 3D point cloud data of outdoor environment in [28]. This data were fed to a 3D Simultaneous Localization and Mapping (SLAM) algorithm to localize the robot in the environment. This point cloud was projected into a 2D plane to make a 2D SLAM algorithm applicable, too. According to this research, the advantages of Kinect sensor are a considerably lower price, and the inclusion of color into the maps in compared to conventional laser scanners. A[A10] system with two main parts was applied on surveillance mobile robot and enable it to have an autonomous navigation [4]. One part is a reactive navigation system. It used Kinect data to avoid obstacles. In this part, the depth map with one row and 5 columns was created using each depth image and pixel intensity of three cells (left, front and right) are analyzed to compute the absolute minimum and maximum distances between sensor and obstacles. Eight different situations and their relevant action commands are determined. A classifying system trained possible situations of an indoor environment using Kinect data in second part of the system. [A1]a mobile robot control law for corridor navigation and wall-following, based on sonar and odometric sensorial information is proposed. The control law allows for stable navigation avoiding actuator saturation. The posture information of the robot travelling through the corridor is estimated by using odometric and sonar sensing. [A2]In particular we deal with the well-known strategy of navigating by wall-following. In this study, probabilistic neural network (PNN) structure was used for robot navigation tasks. The provided files comprise three different data sets. The first one contains the raw values of the measurements of all 24 ultrasound sensors and the corresponding class label Sensor readings are sampled at a rate of 9 samples per second. [A3]The robot navigation is based on wall following algorithm. The robot is controlled using fuzzy incremental controller (FIC) and embedded in PIC18F4550 microcontroller. FIC guides the robot to move along a wall in a desired direction by maintaining a constant distance to the wall. Two ultrasonic sensors are installed in the left side of the robot to sense the wall distance. The wall following control of the autonomous robot has been presented using ultrasonic sensors. The sensor data are used to measure and obtain the distance and orienta- tion of the robot [A4]Some control algorithms based on artificial vision have been introduced, where the robot is allowed to move by following the wall in the corridor like the one introduced by Durrant-Whyte et al. In other research work, Zhou et al. [20] let the robot in their work to identify the heading direction through a vanishing point of lines extracted from the corridor structure. The lines look like they are scattering from one point in the image of the corridor. This one point is the vanishing point. Although it looks easy to extract the lines, but capturing the vanishing point require a complex mathematical calculation. [A5]The problem of controlling the pose of a mobile robot with respect to a target position by means of visual feedback is investigated mainly. The proposed method enables a mobile robot to identify its own position using visual features of environment. At the same time, the robot performs an orientation recognition using the same recognition method of position identification in order to follow a path in environment We developed a visual perception navigation algorithm where the robot is able to recognize its own position and orientation through robust distinguishing operation using a single vision sensor. [A6]This paper describes ongoing research at the University of British Columbia on the problem of real-time purely vision based 3D trajectory estimation for outdoor and unknown environments. The system includes an inexpensive trinocular stereo camera that can be mounted anywhere on the robot. It employs existing scene information and requires no prior map, nor any modifi cation to be made in the scene. [A7] Autonomous mobile robot achieves outdoor navigation by three processes, including the environment information acquired by the perception module, the control decision made by the planner module, and the motion plan performed by the motion control module[8]. Consequently, for safe and accurate outdoor navigation it is vital to harmonize the three modules performance. In this paper, the emphasis is focused on the decision of control laws of the robot, and objects include the longitudinal velocity, the lateral velocity, and the angles of sensor pan-tilts. In an off-road environment, the robot uses laser range finder (LRF) with one degree of freedom (DOF) pan-tilt (only tilt) to scan bumpy situation of the close front ground, on which the robot is moving, and employs stereo vision with two DOF pan-tilt to perceive drivable situation of far front ground. With the data accessed from laser and vision sensors, the passable path can be planned, and the velocities of left side and right side of the robot can be controlled to track the path, consequently, the robot off-road running is completed In this paper, a description of trajectory space[7] is presented according to the robots dynamic analysis, which is defined as the two-dimensional space of the robots turning angular speed and longitude velocity. [A8]This article describes the development of a wall following behaviour using a methodology for the learning of visual and reactive behaviours with reinforcement learning. With the use of artifi cial vision the environment is perceived in 3D, and it is possible to avoid obstacles that are invisible to other sensors that are more common in mobile robotics. the image is divided into a grid made up of 3 rows and 3 columns (Fig. 2(c)) for codifi cation. Each cell will have either free or ocuppied label, depending on the number of edge pixels it contains. Thus defi ned, the state space is 29, and in order to reduce it, it is supposed that if a cell in one of the columns is occupied, all those cells above it are also occupied. [A9]In this paper we investigate the suitability of the Xbox Kinect optical sensor for navigation and simultaneous localisation and mapping. We present a prototype which uses the Kinect to capture 3D point cloud data of the external environment. The data is used in a 3D SLAM to create 3D models of the environment and localise the robot in the environment. By projecting the 3D point cloud into a 2D plane, we then use the Kinect sensor data for a 2D SLAM algorithm. We compare the performance of Kinectbased 2D and 3D SLAM algorithm with traditional solutions and show that the use of the Kinect sensor is viable. Our research indicates that the Kinect is a viable option for use as a sensor for mobile robotic navigation and SLAM. It ofiâ‚ ¬ers signifi cant advantages over conventional laser scanners, such as 3D model building, pure visual SLAM, a considerably lower price, and the inclusion of colour into the maps. [A10]This paper presents the development of a perception system for indoor environments to allow autonomous navigation for surveillance mobile robots. The system is composed by two parts. The first part is a reactive navigation system in which a mobile robot moves avoiding obstacles in environment, using the distance sensor Kinect. The second part of this system uses a artificial neural network (ANN) to recognize different configurations of the environment, for example, path ahead, left path, right path and intersections. The ANN is trained using data captured by the Kinect sensor in indoor environments. This way, the robot becomes able to perform a topological navigation combining internal reactive behavior to avoid obstacles and the ANN to locate the robot in the environment, in a deliberative behavior

Motivational theories Essay

Maslows Theory is based on the belief that we are motivated by needs and the theory states we must satisfy basic needs in order to concentrate on the higher priorities. And only when the basic needs are met can we move on to the next steps 1. Pysiological – All individuals needs to eat, sleep and drink as a priority 2. Safety – WE all need to feel safe in our homes and the working environment and managers can play a lead role in ensuring we care safe at work 3. Belonging – We need to feel loved and belonging both at home with our families but also in our work place 4. Esteem – Once the 3 basic need are met we look for confidence and respect from others especially in our work place 5. Self Actualization – Top of the pile! We have energy and mentality to thinks, problem solve and use our skills to the the best of its ability Maslows theory tends to be very simple, rather easy to follow and makes sense as it cover basic needs that maybe somewhat forgotton about. If making a new start then Maslow theory is ideal as it is very basic and starts from the bottom of all our needs Herzbergs Theory Hersbergs theory is some what different to Maslows theories in being it concentrates on 2 factors and are all work related though Maslows theory starts with basic needs in life 1. Hygiene factors – are Disatisfiers and the less we have to worry about the more we be motivated. Factors such as Quality of supervision, company policies, job security will all have an impact on staff motivation and this would certainly be the case with the council as they have the ability to dissatisfy 2. Motivation Factors – such as Promotion opportunities, recognition Achievment and responsibility will satisfy all staff without a doubt as they can stimulate. These factor all realte to the work itself and how an employee performs it. Overall the Herzberg theory Herzbergs theory show that fixing problems within the work place related to Hygiene factor may narrow down job dis satisfaction but won’t necessarily improve a workers job satisfaction. To improve job satisfaction you must addr ess the motivational factors and press on them ie: giving recognition to staff and showing staff a sense of achievement for what they do. Vroom expectancy motivation theory Whereas Maslow and Herzberg look at the relationship between internal needs and the resulting effort expended to fulfil them, Vroom’s expectancy theory separates effort (which arises from motivation), performance, and outcomes. Vroom’s expectancy theory assumes that behaviour results from conscious choices among alternatives whose purpose it is to maximize pleasure and to minimize pain. Vroom realized that an employee’s performance is based on individual factors such as personality, skills, knowledge, experience and abilities. He stated that effort, performance and motivation are linked in a person’s motivation. He uses the variables Expectancy, Instrumentality and Valence to account for this. Expectancy Is the belief that increased effort will lead to increased performance i.e. if I work harder then this will be better. This is affected by such things as: Having the right resources available (e.g. raw materials, time) Instrumentality is the belief that if you perform well that a valued outcome will be received. The degree to which a first level outcome will lead to the second level outcome. i.e. if I do a good job, there is something in it for me. This is affected by such things as: Clear understanding of the relationship between performance and outcomes – e.g. the rules of the reward ‘game’ Trust in the people who will take the decisions on who gets what outcome Valence Is the importance that the individual places upon the expected outcome. For the valence to be positive, the person must prefer attaining the outcome to not attaining it. For example, if someone is mainly motivated by money, he or she might not value offers of additional time off. The three elements are important behind choosing one element over another because they are clearly defined: effort-performance expectancy (E>P expectancy) and performance-outcome expectancy (P>O expectancy). E>P expectancy: our assessment of the probability that our efforts will lead to the required performance level. P>O expectancy: our assessment of the probability that our successful performance will lead to certain outcomes. At first glance expectancy theory would seem most applicable to a traditional-attitude work situation where how motivated the employee is depends on whether they want the reward on offer for doing a good job and whether they believe more effort will lead to that reward. However, it could equally apply to any situation where someone does something because they expect a certain outcome. Thus, Vroom’s expectancy theory of motivation is not about self-interest in rewards but about the associations people make towards expected outcomes and the contribution they feel they can make towards those outcomes. McGregor Theory X & Theory Y McGregor developed two theories of ‘human behaviour’ at work: Theory and X and Theory Y. He did not imply that workers would be one type or the other. Rather, he saw the two theories as two extremes – with a whole spectrum of possible behaviours in between. Theory X workers could be described as follows: – Individuals who dislike work and avoid it where possible – Individuals who lack ambition, dislike responsibility and prefer to be led – Individuals who desire security The management implications for Theory X workers were that, to achieve organisational objectives, our Business would need to impose a management system of coercion, control and punishment. Theory Y workers were characterised by McGregor as: – Consider effort at work as just like rest or play – Ordinary people who do not dislike work. Depending on the working conditions, work could be considered a source of satisfaction or punishment – Individuals who seek responsibility (if they are motivated) The management implications for Theory X workers are that, to achieve organisational objectives, rewards of varying kinds are likely to be the most popular motivator. The challenge for management with Theory Y workers is to create a working environment (or culture) where workers can show and develop their creativity. (www.tutor2u.com) Maccobys Theory of Motivation Michael Maccoby suggests that in order to motivate staff, leaders should employ an appropriate mix of the 4 Rs: Responsibilities, Relationships, Rewards, Reasons. Responsibilities People are motivated when their responsibilities are meaningful and engage the abilities and values. For example our caring staff are motivated by helping others like teaching and mentoring. And our craftsmen are motivated by the challenge to produce high quality products. Relationships People are motivated by good relationships with bosses, work colleagues and customers. Someone who is caring is motivated if they have the chance to help colleagues and customers. Also a strong team of colleagues who have a strong bond will be motivated to keep the bond strong. Rewards Apreciation and recognition are the kinds of rewards that strengthen motivating relationships. Rewards such as Bonuses, recognition, promotion will all motivate an employee to try their best and push for results. This is also the case when people are painf fair wages and good benefits to make a good job. Reason Reasons can be the most powerful motivator of all. Why are we doing the job over and over again? What is the point of it? If workers have a good explained reason on why they are doing what they are doing then they will be motivated to carry on. For Example workers doing assembly line work during World War II were highly motivated as it was there contribution to the War effort and the aim of winning the war. Evaluate the Usefullness of one motivational Theory for Managers As above you can see all of the theories show different ways in which motivation can be achieved and all have their pro’s and con’s. During this time of change I feel that MaCobys theory of motivation would definitely be of use to all Managers in motivating our staff. Let me explain why: The for R’s are in my turn very easy to understand for Managers and staff, Responsibilities, relationships, rewards and reason are all very simple terms. Responsibilities First and forth most it is of vital importance that our staff know their responsibilities. Have the jobs changed? Have working conditions changed? How can we get bring the best out in our staff. The time is right to evaluate responsibilities, alternate jobs and give staff more of different roles responsibilities. Managers need to show that they are willing to develop all staff. Teach new skills and give them the responsibility to bring the best out in them. Relationships Team bonding is essential during this time of change. Managers need to concentrate on building good strong relationships with there staff so that they can build trust and a sense of security. It is also important that Line Managers keep the relationship of the team of individuals strong and a need to identify any rifts or issues. During this time, new staff will be bought in, existing staff may leave or be moved or transferred so the manager must keep in constant contact with the staff and ensure that the communication amongst staff is strong. Rewards Managers need the opportunity to reward staff for their efforts. The chance of promotion to a higher vacant position will certainly motivate the staff but of course this can not always be the case so recognition for the services provided by staff will certainly go along way. The annual Council forum is an excellent way of achieving this as is provides recognition and rewards for staff who have been committed to the Council, staff who have a good absence record and also staff who have achieved a major goal in the work force on a under graduate qualification.

Chosen business: Tesco Essay

There are different types of information that Tesco use these are: – Verbal information: This is spoken information it could come from the customer, it could also come from Tesco if they let any promotions over the tannoy. – Written information: This is information that is written in a document, Tesco uses this type of information in its leaflets, receipts and collects this information from customers through comment cards etc. – Onscreen information: Tesco will use this type of information in their TV adverts so that they can get a lot of promotions across to their potential customers, they can also use this to show customers how good they are compared to their competitors and that their products are cheaper. – Multi-media: This type of information is a lot of different sources mixed in, it includes pictures, presentations, videos and can include on screen information, Tesco does not normally use this type of information because they tend to use types of i nformation that they can easily communicate with their customers such as verbal or written in the form of a leaflet or poster. – Web based: This type of information is given out or collected through the internet, Tesco have a website that they use to communicate information on the business to their customers. Customers can also give information through this by buying products online and giving reviews on Tesco. Tesco use these types of information for many different purposes, these are: – Updating knowledge: They use information to update their knowledge on things like what products are selling the most and which ones have high demand, they can then make sure that they supply all of these products for the customers, they can find this out by questionnaires etc. and also written sales figures and this will update their knowledge on what products are their best sellers so they can promote these. -Informing future developments: They use information to inform their future developments because if they can get lots of information from their customers then they can use this to make plans for their fut ure developments in order to make their organisation better, they can use customer feedback via written information. -Strategic direction: They use different types of information in order to decide which strategic direction they are going to take, they can use sales figures and department feedback to see what is making Tesco do so well. If they come across a problem, like they do not have enough sales then they can use this information to change their strategic direction. -SWOT analysis: They use both internal and external forms of information in order to see what their strengths, weaknesses, opportunities and threats are. Tesco will use sales, customer, department, competitor and growth information in order to conduct a swot analysis they will then find that their strengths are having specialist marketing expertise because they are such a huge organisation they know what they are doing. They also have weaknesses such as a large amount of competitors that could overtake them such as Asda and Morrison’s. An opportunity could be the development of technology such as self-scan machines that they can use to promote their business. A threat could be how Asda is currently top of the market and this means that they need to come up with more ideas to get above Asda. -Offering competitive insight: They will use information such as market share and published sales figures from other their competitors to see how good other competitors like Asda are doing they can they use these to see what they can do better. They will also use the on-screen information such as the TV adverts to get a competitive insight because they will see what offers their competitors are doing and try to match or outdo these. -Communicating sales promotions: They use both written, on screen and verbal information in order to communicate their sales promotions, they will do this because by using more than one method of information they can get more information and better information out to their customers and it will mean that more of the customers are likely to see the promotions and buy the products. -Inviting support for activities: They can use onscreen and written information to do this because if Tesco are holding a fundraiser then it is important that they can get this message out to their customers and staff so they will hand out leaflets on the activities they are holding and advertise it on the television for people who are not coming into store this will invite support. They can also use written information such as messages on bulletin boards in the staff room to invite support for new technology in the business such as new ICT and then staff will be able to voice their support or non-support for this new software etc. There is lots of places that Tesco get this information from, these can be both internal and external: Internal -Financial: This is a place where Tesco can get their information from because if Tesco is doing well and generating a profit then they know that they are doing something well and may not need to change their strategic direction if they are constantly growing and generating more money. -Human resources: This is a place where Tesco get their information from because they can tell them if the staff are good enough to do their job for example, do they have the right skills to do their job. Human resources can also give them a lot of information such as training that they are giving then Tesco can use the staff for different things because they will be trained to do this. -Marketing: This is a place where Tesco can get information on how departments are doing but they will also use this to give information out to their customers for example Marketing can advertise the promotions and create the adverts, they can also market new products that come into the business so that customers know what products exist so that they can buy them. -Purchasing: This is a place where Tesco can get their information because they will get information such as if they are getting a good deal on all the products that they are buying for their stores, they will also get information such as are they having good suppliers where deliveries arrive on time. -Sales: Tesco gets information from their sales because they can look at their sales figures to see what products are selling the best and what kind of products have high demand, they can then make sure that they make the most of these products and promote them more so that customers buy more e.g. Warburton’s because customers buy bread very often so it is often on promotion in Tesco. -Manufacturing: Tesco make their own brand products, they get information from this because they know how much it is costing them to manufacture these products, they can then put a reasonable price on the products so that they are giving their customers the best deal and they will be able to make profits if they know how much the product is going to cost them to manufacture. External -Government: Tesco get information from the government on things like how much they can legally pay their staff e.g. minimum wage, this is important information because they can use this to not spend too much on wages if they don’t need to but also to protect their staff. -Trade groupings: Tesco can use the information they get from trade groupings for things like their competitors because they will be meeting with these people and can then gain more of an insight into their business and Tesco can improve to be better. – Databases: Tesco can use the information they get from external databases in order to help their organisation, they can find out independently published databases on the sales of individual products that they sell. They can also get databases on how other competitors are doing so this information can help them to change their strategic direction if they need to. -Research: Tesco can do their own primary research into products and their customer service to see how they are doing but they can also use external secondary research, this can be done on forum sites where customers have reviewed Tesco and they can also do secondary research from people who have already published research and they can use this. -Reliability of data sources: If Tesco does a lot of secondary information then it is important that they find out how reliable to sources of the data are, if the person who took out the research is a reliable source e.g. a government source then they can use this well because they know that the information is reliable and will not mislead them but if it is from an anonymous source then it is not likely to be reliable and may be biased so it might not be the best idea to use this as it may lead to Tesco making wrong decisions. Task 2 (M1) Verbal information is an appropriate way of communicating and gathering information in Tesco because it allows for Tesco to get their information to their information to the customers quickly and would allow for Tesco to get all of their promotions out quickly and often verbal communication is a more persuading way of giving information and by giving the promotions verbally Tesco may be able to persuade their customers to buy more, so this would be an appropriate way for Tesco to get the information it needs across to its customers. The source of verbal information can come from sales, I think that this is an appropriate source for verbal information and for information in general because it comes from the customer themselves, it is normally a one on one encounter with the staff and the customer so this means that information is less likely to be manipulated because there is less people for it to go through before it can get used, so this source is reliable and valid because the info rmation is coming direct from the customer or the information is coming directly from the seller for promotions etc. Another type of information is written information, when Tesco uses this it is normally in the form of leaflets so that they can show their customers what is on offer at Tesco, it is an important and effective way of getting information across to the customer because it means that they can read it anytime they want, even when they are not in the store they can pick up the leaflet and see what is available at Tesco. Written information allows for the customer to view the information any time they want and it allows for Tesco to get the information out to many people at once, verbal information may not be appropriate when trying to get a lot of information out to a lot of people because it is often not possible to talk to many people at once other than a tannoy and also verbal information will only allow for information to be passed to people who are in the store at the time whereas written information can be given to people who are not in store. The source of written information could be marketing within Tesco, this is an appropriate source of written information because marketing has the right skills in order to make an effective leaflet that gets all of the information needed to the customer, they know from other departments what information needs to go into the leaflet e.g. what promotions are on or what jobs are available via human resources so they can then market and advertise this in a way that will attract customers to take and read the information. The final type of information that Tesco use is on-screen information, this is in the form of TV adverts and sometimes on screen adverts in store, this is a good way of getting information across to the customer about things that might be going on at Tesco e.g. new products or events that are being held. On-screen information is a good way of giving out information because customers will still remember what they have seen even after the advert has finished and this means they will remember what is happening or what products there is and if people see something they are interested in then they are likely to go and buy it as a result of the on-screen information, it also allows for Tesco to run adverts even when the stores are not open, it also allows for them to advertise directly to the customer in an environment that they are comfortable with because most people watch the television at home and will be relaxed and more likely to take in information. It is reliable because it has come directly from Tesco which means all of the information is what they want to share and all the information is correct. A source of on-screen information at Tesco is the marketing department, they are responsible for advertising and marketing all new products and generally advertising the organisation. They will be able to make the information clear and attractive using multimedia and on-screen and if customers are attracted to an advert they are likely to listen and be interested, allowing for the information to be shared to the customer. Marketing is a good source of information for on-screen because they know what they are doing and have the right skills to make an effective advert that is fit for purpose.
