OVERVIEW Low-fi Prototyping Usability Testing Mission Selected Interface Prototype iteration Usability Testing Method Results Learnings

Low-fi Prototyping

MISSION HealthMap Stay confident and accountable about your health before getting in a car.

INTERFACE Why mobile? Quick & Efficient We sketched 15 - 20 sketches over 5 modalities: VR, AR, Wearables, Hardware device, mobile Why mobile? Quick & Efficient

PROTOTYPE

ONBOARDING

TASK 1 “I want to know if I am fit enough to drive” – Complex vision Hearing Reflex Stress if passed if passed if passed Vision Hearing Reflex Stress Tests are presented sequentially. If passed all tests, then show the “you are all set screen” The whole process should take less than a minute. Each task is about 10 - 15 sec. If interrupted, start from the particular test. Timeout if it exceeds 1 min. if passed all tests “I want to know if I am fit enough to drive” – Complex

“I want to know how to be a safer driver” – simple TASK 2 If had inconsistent results vision If the user had inconsistent results in any of the tests, we prompted them with a caution screen, and showed them suggestions. reflex “I want to know how to be a safer driver” – simple

“I want to get help when I need help” – moderate TASK 3 User Taps CFH EC accepts call Emergency Contact “I want to get help when I need help” – moderate

Usability Testing

METHOD 3 participants @ Tresidder Diverse demographic background Not incentivized Given a scenario and asked to complete each of the 3 tasks We tried to cover a diverse age group of people that drive on a regular basis. We asked them if they would be interested in participating in a short interview to give some feedback for a course project. We followed the script to first give each participant some explanation on the high-level goals of the product, and then gave them a scenario and asked them to complete each of the 3 tasks, while thinking out loud.

RESULTS P1 Quickly identified the intention of the product Panda Express Employee 19 yrs Commutes daily in car Confused about the text largely due to his level of education but it is a strong indication that we should make the test understable to various audience groups. Quickly identified the intention of the product Appreciated relevance of the tests for driving Confused by the text description of vision test

RESULTS P2 Excited about the reflex and stress tests Entrepreneur 64 yrs Commutes daily in car “People are not receptive to machines telling them not to drive, they may drive anyways”. Excited about the reflex and stress tests Surprised that HealthMap is self-interpreted Preferred to call 911 instead of preset emergency contact

RESULTS P3 Impressed with the stress test Teaching Staff 36 yrs Commutes daily in car e.g., when she is in a car accident Impressed with the stress test Liked that HealthMap is easy to set up Wanted to have an emergency call button without going through the tests

LEARNINGS Make test description understandable e.g., add audio cues + visual cues Change the size of the number in vision test Enable emergency calling that bypasses tests e.g., user can dial 911 in one click. Feed user’s and family’s health information and history e.g., this info will help paramedics in emergency

SUMMARY Low-fi prototyping Prototype testing Usability-wise Feature-wise Hope to validate our design changes in future studies

THANKS! Any questions?
