Brainstorming Session Summary

Scenario 1. Rear-seat HMI interaction for kids

Children are required to be seated in the rear-passenger row with restraint systems.  Comforting children and providing entertainment to them not only makes them happy, but also helps their parents focus on driving.

Design Question: How can we use gesture in rear-seat HMI design to meet the needs of children between 4 and 12 years old?

Group 4: [Lost in transportation]

Scenario 2. Gestures assist driver in motion

The one-way commute time for an average American is one hour.  We spend a lot of time on the road. Sometimes, nothing can keep us away from multi-tasking. We may answer phone calls, change music, look up routes having the least traffic, etc.  Voice, touch- screen and remote controllers may not be enough to keep us safe while getting everything done efficiently.

Design Question: How can we use gesture to help drivers who are in motion?

Group 5:  Enhancing Social Interactions through Gestures

Use-case 1

Apologizing to car behind when after unintentional poor driving

Car X:

  • Locating vehicle (Car Y) to communicate with = Finger point to near view mirror
  • Visual feedback correct car located
  • Speak word “Sorry”

Car Y:
