Final Report

My response to this project was to develop a product that could help people. I thought of a device that could help people find there grocery's in supermarkets.my device is perfectly suited for family's and people who are looking to find food easily in stores.I hope my device will be small practical and easy to use.
My first priority was to look at ways this could be done and the technology behind them. To do this I
looked at RFID a form of data tracking which is used in most stores to help find products, keep stock and organise them. It reads barcodes but it can read them while the items are moving. It is similar to other forms of tracking like Wifi, found in stores, Internet cafes’s and some phone box’s in major city's.
Bluetooth is also something I thought of using as it’s a device that transfers data in a short range, which in a store full of products all within close range I believed this would be use full. I also looked at barcodes and how they work in stores read by RFID but are also read by USB scanners.
so even after looking at these major forms of data trasference I discovered that my device would be better as a application they are found in I-phones and mobile devices. They are easy to download and are easily available online. The program works by using the application software to use RFID to lock on to the location of the item and directs the customer to the item in question.
The user must first turn on the device enter the items into the application and then go to the store. The RFID scans the items and transfers the data back into the device. It also helps the user by telling them how far the items are and also alternatives if the customer cannot find or wants a cheaper option. I feel companies may want to purchase this device like Tesco or ASDA because it will speed up shopping for customers make things less stressfull and suggestive sale for the users which will increase profit for the company's. However if it is a child or old age pensioner it will not do suggestive sale as this this is taking advantage of there age.
I made some sketches of the device and what it will look like on my device and how it functions and works. I thought perhaps this way it would be easy to show how the product works and how the user can manage it. More importantly demonstrates how simple the item is to use in a crowded store. As the application is found in mobile phones it will be light weight and easily moved around. Easily accessible and its destined that way so it will be comfortable for any user. But also because they will be expert users of a phone and novice users of the device it will also be simple to learn how to use and access.
I looked at the Christene Faulkners Theories of computer interaction found that applications, software and programs and found that her theories help me develop what my device should or should not do. They should be easy to function and should give sufficient feedback and they should have not have too many options to confuse the user.they should also give help the user and that no special training will be necessary. This can be found in the book called The essence of human computer interaction where she has many theories on how applications and software should work.
I found after the application “Tasty tracker Mk 1” was completed I was satisfied how the software would work and how the application on mobile phones would work. I feel that this idea will benefit shoppers and family's alike and that it will enrich the shopping experience.
