We sequentially tested two paper prototypes on six different users. Each user is referred to as User A to User F. Users A, B, C tested prototype version 1 and Users D, E, F tested prototype version 2.\
Due to the nature of our application, we wanted to emphasize testing the usability of our user interactions.
...
- Pretend that your hand is the mouse cursor to interact with the UI. Feel free to move your hand around and point to where you want to click
- Please identify when you want to single click, double click, left click, right click, or drag your simulated mouse cursor (i.e. your hand)
- Do NOT pick up the playing cards - the “computer” will perform all actions for you
Scenario Tasks
1. Shuffle the deck of cards
2. Deal deck of cards evenly to 3 other players
3. Play cards (as instructed by the facilitator)
...
- Double click on “down” card immediately plays that card. Double click on “up” card plays all “up” cards
Version 2 Testing
Observations
- Users D, E, F all selected entire deck using double click after at most 2 tries
- Users D, E, F all efficiently dealt cards without error after performing shuffling task
- Users D, E, F all played single desired card from hand after at most 2 tries (either discovering dragging or double clicking)
Usability Analysis

- User E specifically mentioned that all interactions were “straightforward”
...
Efficiency
...
- user initiation of automated actions enabled very efficient completion of shuffling and dealing tasks
...
Errors
