This is the app I created for the 2018 Congressional App Challenge.
The app is a calorie counter in which the user inputs their height, weight, age, and whether they want to lose, gain, or maintain their weight.
Basic menu using a moving focus model for TV apps such as Hulu, Youtube etc. Key presses are used to map interactions which would be mapped to physical remote controls for live demos.
Note: Must click the canvas to enable key presses, this seems to be a common restriction with most prototyping tools when building key press focus interaction models.
