Overview
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.

Metadeck by Haitao Mao and Victor J Wang
...
Metadeck is a card playing user interface that emphasizes user control. The main objective is to provide users with intuitive interactions with a virtual deck of playing cards in free-form, mimicking the experience as if users were playing with an actual deck of cards.
You have three tasks:
- Shuffle the deck of cards
- Deal deck of cards evenly to 3 other players
- Play cards (as instructed by the facilitator)
Important things to keep in mind:
- 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
