After evaluating this setup with users and their feedback, we have inferred the following :

​

  • The mobile app screen should contain the notifications on the main screen as it had too much clutter and they wanted to see the notifications right away

  • The return button could be removed from the mobile screen as to reduce visual clutter

  • Devices could be put in a settings screen

  • A list of previously suggested products would be useful

  • The system setup(the first setup) itself could be packaged in a better usable way

​

With these findings, we would refine and develop the system’s various aspects to implement the actual prototype.

The Wizard of Oz evaluation method gave us an opportunity to test our rudimentary system with a user before we could implement it. This helps in avoiding costs that could be incurred once the system is implemented. Based on our evaluation, we take away key points on how the system needs to be designed to satisfy user needs.
