Kidz Korner is an interactive adventure story using gesture-based interactions.

PurposeUse a computer-augmented environment to enhance children’s imagination and coordination

ScopeResearch and entertainment

2. Existing Systems

KidsRoom

Disney’s Aladdin

3. Design Criteria

A beginner user should:

Locate the right on-screen keys at their second visit

Bypass 75% of the obstacles at their second visit

Make less then 3 gesture errors

Succeed in completing the adventure at their second visit

4. Storyboard

Initial Design Decisions

Feedback Crouching gesture Buttons location Repeat the tutorial

5. Prototype

First Computer Prototype

7. Beta System

Implementation in the SRE lab Gesture-based interface

7. Beta System

Known Limitations

Tracking of the vertical (y) coordinate

Usage Scenario

Video demonstration

8. Future Improvements

A step further...

Enhanced graphics

Better interaction between children and the system
