1. Motivation & background information
1.1. Motivation
In recent years, the use of mobile applications has penetrated to our daily lives deeply as we rely them for several different purposes in our smartphones. To name a few, for communications, we uses messaging applications including Whatsapp, Skype and Wechat. For entertainments, we also have media applications such as Facebook, Twitter, YouTube and 9GAG, and mobile games like Angry Birds, Temple Run and Candy Crush. While for transactions, we get many mobile banking systems offered from banks such as HSBC Mobile Banking and Hang Seng Mobile Application. From these well-known examples, it is undeniable that developing mobile applications is now a current tread in the market. In the old days, we can only check for the details of the product from websites, but in contrast, due to the high portability of mobile devices, we can now use mobile applications to locate useful and updated information at anytime and anywhere. Consequently, owing to the high potentials of mobile application in the market, I would like to develop a mobile application which aims to improve people’s quality of living for my final year project.
1.2. Background information
There are some existing websites for users to browse and search for the information about items available in stores, yet they are not detailed enough.

Take an example from the website of PARKnSHOP (URL: http://www.parknshop.com/), a supermarket from Hong Kong, the users can only find out the brand name, product name, weight and prices from the webpage. In fact, when the consumers are making decision on products, they would also consider many other types of factors, such as nutrition values, ingredients, origins, and comments from the public. However, these information can only be found on site instead of the website. It would be more convenient for the users to locate the detailed information on their mobile devices.

Moreover, from the


2. Problem statement, project objectives & scope
2.1. Problem statement
Once we walk into the supermarkets or stores to shop for goods, we may encounter some common problems which are quite time-consuming to solve.
For example, when we want to buy a product without any known brands on the shelves, we may feel confused about which brands of products to buy as there are too many choices available. As a result, we may need to compare each brand of products one by one before we pay. However, time is money for most of the Hong Kong citizens, we have many other more important things to do, thus, we have limited time for consideration.
On the other hand, people who demand for special requirements on their meals, especially those who are dieting or suffering from food allergies, need to spend extra time in reading and analyzing nutrition values, origins or ingredients from the labels on the products. While they are making comparisons, it requires much of their memorizations and time to remember those information printed on products.
Furthermore, owing to the selling price differences between products in different shops, some consumers would like to compare prices in different locations to obtain the most economical purchase in order to save money. Especially for those housewives, they are willing to walk around the nearby stores to search for products with lower prices. As a matter of fact, even though they can save money from this way, the whole process is not economical in terms of time cost.
2.2. Project objectives
2.3. Project scope
Collect items’ information through crowdsourcing - The user can submit the detailed product information to the application which will then be stored in the database of the server-side computer. These information includes brand name, product name, nutrition information (energy values of carbohydrates, proteins, sugars, total fat, cholesterols, etc.), ingredients, origins and volume or weight. They can also upload photos for the products so that it would be easier for the viewers to identify the specific items.
Browse the detailed information of items - With the data provided by crowdsourcing, the system can display all the available items or according to their categories and subcategories.
Comment, like and share items to relatives and friends - What the users can also provide for each item are their comments and likes. With regards to the comments and likes of the specific item, the users can find out whether the item is worth buying or not. Also, the application will utilize the social plugin from Facebook, so that they can be shared the link to the social network and help to spread over the entire community.
Search for the available items

Help to identify differences between selected product - Developing a mobile application which can clearly specify the differences between each brand of products can help to save the user’s precious time and improve the quality of life. It would be nice if there is a mobile application which can help them to record down all the updated selling prices in different locations. Thereafter, they do not need to spend extra time in collecting information about the product prices.
Provide updated products’ prices and location -
When the user is deciding on which brands of food to buy from, he/she can input the keywords, like the type of the food, the corresponding category or even the ingredients, to search for a list of available food that suit the demands. What can be obtained from Food Magnifier is the detailed information about the food products including the names, brands, energy values, nutrients (values about carbohydrates, proteins, sugars, total fact, cholesterols, etc.), ingredients, origins and volume or weight from the database. Moreover, it allows the users to rate and comment on the food products which may also help us to shorten the time for decisions. On the other hand, the users can be one of the contributors to the application because they can add the data of the food products into the database. The reliability of their data will be judged by the number of views or likes, and also the background status of the authors. Upon their submissions of information, they will be awarded with rewards points which can be used for exchanging coupons or earning discounts in the shop.
