Second Prototype

Learnability

Transitions between group/individual components and between users were not clear

  • Same problems as with the first prototype.
  • We should add full-screen indications that the app is switching between users, or from group to individual mode.

The purpose of some screens was unclear

  • In particular, the screen showing restaurant choices and providing restaurant info does not allow voting, and this was not clear.
  • It is also possible that the restaurant choices/info screen is not necessary at all, and could logically be combined with the voting screen.

Not clear why the group suggestion-making interface exists

  • Users are allowed to make only one choice for each criterion, so it is not clear why the group may make an arbitrarily high number of suggestions.

Inconsistent UI elements

  • Some screens use right-pointing arrows, and some screens use "Done" buttons.
Efficiency

Information should be presented in a more accessible fashion

  • The "add cuisine" list should be organized in a meaningful fashion.
  • The betting screen should show a counter for each criterion, indicating the total number of chips placed there (instead of having to count the number of chips on that spot).

The restaurant choices/info screen and the restaurant voting screen should be combined in order to reduce screen transitions
