Problem Statement

UL Purple

People touch their face 23 times/hour on average, of which 10 touches are to the eyes, nose, or mouth. Keeping hands clean helps prevent the spread of germs, like COVID-19.

How might we leverage Samsung's wearable technology to remind people to wash their hands and help build the habit over time?

Learnings from User Testing, VoC, App Analytics

UL Purple
1 Purple

Touch interactions to start hand wash are not suitable as users don't prefer to touch the watch with unhygienic hands

3 Purple

Users don't prefer downloading a specific watch face just for Hand Wash. They want the watch faces to match their attire and daily needs

2 Purple

Setting up time-based reminders doesn't work for users, as their daily schedules vary. Users want wash reminders after tasks that involve hands

4 Purple

Over time, the hand wash goal creation and completion cycle becomes monotonous, and users lose interest
