Pebble Tangible Interaction Design

In between the the release of the first and second generation of Pebble Time devices, I worked on a team exploring advanced device interactions. This particular exploration was around nuanced haptics performance and interaction. I created testing rigs and interviewed users based on difference haptic systems and implementations in the context of our wearables. The results of both the hardware and software explorations were then implemented in the 2nd and 3rd generation devices.

 
 We mounted different ERM (eccentric rotating mass) and LRA (linear resonant actuator) motors to different locations on weighted shells to test performance.

 We received feedback from multiple users on factors such as minimum detectable motion as well as the ease of identifying patterns.

 Mounting the motors off axis resulted in the most noticeable vibrations.

 In addition, tangential radial motion and any linear motion produced noticeable feedback improvements when compared to the motors used in the very first Pebble devices.
