2. AirRacquet System – Team Innovation2/16 Introduction Purpose:Gesture based racquet game with intuitive interface Design:Iterative, user centered, changes motivated by feedback Scope:Entertainment, training, research

3. AirRacquet System – Team Innovation3/16 Conventional Systems Improvement has been made in graphics and flexibility User interface has remained static User is more of puppet-master than player

4. AirRacquet System – Team Innovation4/16 Benefits of AirRacquet User is immersed into the environment Gestures provide natural mapping to actual game play

5. AirRacquet System – Team Innovation5/16 Design Goals Typical User: Over the age of 12, familiar with ping-pong, no knowledge of supported gestures needed Focused on: Conceptual Model Feedback: Visual and audio Natural Mapping: Gestures and ball behavior Visibility: Menus and Game setting

6. AirRacquet System – Team Innovation6/16 Storyboard Menu Module

7. AirRacquet System – Team Innovation7/16 Storyboard Game Module

8. AirRacquet System – Team Innovation8/16 Paper Prototype Feedback Possibility of error in menu selection Unclear vocabulary Improvements Addition of deliberate selection gesture Addition of “Add Default Setting” Change of the word “Gravity” to “Bounciness”

9. AirRacquet System – Team Innovation9/16 Initial Prototype Ball size varies with proximity Racquet moves with the position of the hand Score displayed Help figure and messages displayed

10. AirRacquet System – Team Innovation10/16 Initial Prototype – Feedback Strengths Good visibility of the menu depth Easy to grab the game concept Game Weakness Difficult to hit the ball Distracting instructions flashing on the net Lack of feedback during game play Pause state unclear

11. AirRacquet System – Team Innovation11/16 Alpha system Major change: Ping-pong game Adapted from Cannon Smash (http://cannonsmash.sourceforge.net/) Perspective view Position of ball One Racquet  Two target ellipses (Forehand and backhand)

12. AirRacquet System – Team Innovation12/16 Alpha system Options menu simplified Start game in Main Menu Feedback about winning and losing points

13. AirRacquet System – Team Innovation13/16 Beta System Pause figure moved Pause gesture changed Visibility: Colors modified How to: Audio added Gestures incorporated  Hitting/Clicking  Selecting (Menu mode)  Moving around (Game mode)

14. AirRacquet System – Team Innovation14/16 HCI Principles User centric approach Iterative design Importance of conceptual model Perception of system Feedback Natural mappings Gestures

15. AirRacquet System – Team Innovation15/16 Future Improvements Haptic feedback – ball impact on paddle Network functionality – 2 player mode Improved gesture recognition Rendering of the game setting

16. AirRacquet System – Team Innovation16/16 Conclusion User centered design Iterative Systems must incorporate proper conceptual model Importance of natural mapping Importance of evaluating the user and the environment first
