Users’ Suggestions

This analysis is used to explore how usable the application is.

1. 73.97% Satisfied with the services provided.

2. 5.20% have no idea.

3. 20.83% said that they have new ideas for improvements: 55% of them are females, 45%

males.

The following is a description of users suggestions:

1) Enable the user to write his feed backs and read other users comments.

2) Improve the calories page so the user can know more information about the calories he has to eat and burn.

3) Allow the users to share their Best or Worst Experience with Diets.

4) Allow the user to suggest some products that are not available in the market, so the providers can know Market needs.

5) Show new items available that is suitable to the user.

5.2.5 Differences Between the two versions of “EZBuy: My Product Info” 

Based on users’ suggestions we built the second version of our system “EZbuy2”. After using both versions of the system, users answered a satisfaction questions to indicate which one they prefer, so a series of dependent sample t-tests were conducted to answer the question: Is there a significance difference in the importance before and after modifying? Table 5 shows the results.

Figure 28: Differences between EZBuy1 & EZBuy2 

The results show that users accept the full and modified version of our system “EZBuy2” more than the first version of EZBuy. Users are more satisfied of the new system. We think this is because:

1- EZbuy1 only tells consumers if they can eat this product or not, but EZBuy2 also provides why they can’t for example; not suitable for your health condition because high cholesterol and you have high blood pressure.

2- EZBuy2 calculates how percentage the product is suitable to users.

3- EZbuy2 includes consumers’ suggestions and an improved user web page that enable consumers to find a lot of medical and health information.

4- By using EZBuy2 consumers can interact with each other and also interact with vendors.

VI. Conclusion and Future Work

6.1 Conclusion  

In this thesis, we presented a system that eases consumer shopping and maintains consumer preferences. Because people recently have been willing to see more services that solve their daily problems on their mobile phones, we proposed and implemented “Preferences Monitoring” system.

The system enables foreign and local people in a country to maintain their preferences, cultures, religions and health routines while shopping. After testing the system, we concluded that integrating the used barcode system in markets with modern mobile phones and middleware technologies has the potential for improving people life. However, there are still issues in this field requiring more consideration such as supporting different mobile phone platforms, implementing efficient barcode recognition algorithm, and deploying up-to-date middleware technologies.

6.2 Future Work 

Our future work will contain testing more services of the system in real databases and integrating the system with multiple mobile phone platforms such as Android and Windows. Although the experiments have show a great acceptance from users, further experiments shall be performed to see if vendors will accept our system. The system can also be modified to use SMS communication in addition with 3G and Wi-Fi. Also, it can be modified to enable the user to choose the language used to display products information.
