1. Kidz Korner A Gesture-Based Immersive Environment Geneviève Bertrand Jonathan Gravel-Guérin Patricia Pinard Tuesday April 6, 2004

2. 1. Introduction Kidz Korner is an interactive adventure story using gesture-based interactions.  Purpose Use a computer-augmented environment to enhance children’s imagination and coordination  Scope Research and entertainment

3. 2. Existing Systems  KidsRoom  Disney’s Aladdin

4. 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

5. 4. Storyboard Initial Design Decisions Feedback  Crouching gesture  Buttons location  Repeat the tutorial

6. 5. Prototype First Computer Prototype

7. 5. Prototype Feedback From Choreography Assistant  Strengths Simple gestures Adequate representation of time Control of the game Tutorials  Weaknesses Lack of context User’s progress not visible No option to restart a new game No confirmation upon exit

8. 6. Alpha System

9. Feedback on the Alpha System  Strengths Tutorials Shortcut to skip the tutorial Confirmation messages  Weaknesses Lack of feedback on gestures Inconsistency in buttons’ appearance

10. 7. Beta System Implementation in the SRE lab  Gesture-based interface

11. 7. Beta System Known Limitations  Tracking of the vertical (y) coordinate Usage Scenario  Video demonstration

12. 8. Future Improvements A step further...  Enhanced graphics  Better interaction between children and the system

13. 9. Conclusion  Design Techniques Iterative process User-centered design  HCI Principles Error prevention Visibility of system status (feedback) Consistency

14. 9. Conclusion Questions ?
