Conclusion

Disadvantages

  • Disorganised Main menu, Rather than using a quit button on every page if there is a Main menu button or back button will help to develop usability issues
  • When there is a quit button user cannot understand whether to exit the program or exit to main menu.
  • Developer has used lots of colours and buttons all over the screen making hard to understand.
  • There is only one help screen, user cannot get help for each task
  • Poor navigation in some areas of the application (Eg. Game Room)
  • Poor quality audio clip, some of the voice messages are poor quality.
  • Poor image quality
  • Use of same button for different task (eg. Quit button in main menu has been used throughout the application.

Advantages

  • User can learn the alphabet in fun way (eg. after completing each task user will be rewarded by a game)
  • Use of animation, Without putting still images developer has used animated images giving more interactivity to application
  • Interactivity, (Eg. Each action return a Voice Message or Animation makes event driven program.)
