Main User Feedback
Problem 1. The initial prototype had the keyboard reversed, which confused the user and impeded on the task flow
Solution: Place the keyboard for input on the left hand side, and the action on the right
Problem 2. Insufficient error prevention which caused the user to have to start from scratch if an error was made
Solution: Include a "Go Back" button at the bottom as well as the top of the interface
Problem 3. The starting screen was received well, however users were not sure how to initiate and tapping the screen was not clear enough
Solution: Add copy that instructed the user to "tap screen to begin"
Problem 4. The accessibility directions were at the top of the screen, which was shown to be too high up for users in a wheelchair
Solution: Move button to the lower third of the screen for easier access
Problem 5. Emergency help button on the sleep screen was too high up. Some users suggested it be lowered in case a lost child needed to reach it
Solution: Move the button to the lower portion of the screen. Adults had no problem extending the reach downwards and this change makes the interface more child friendly.
