Agenda
•
Pointer functionality
•
Accelerometers
–
Understanding accelerometers
–
Gesture recognition algorithms
•
Wii Sports case study
–
Steering
•
Wii Balance Board
3D Pointing: Targeting
•
Aiming or Choosing
–
Onscreen feedback required
•
Hand Shakiness is an Issue
–
Use KPAD smoothing
–
KPADSetPosParam(chan, play, sensitivity);
•
<play> should be between 0 and 0.05 (full range [0,1])
•
Find ideal settings with "kpadsample" in SDK
•
Only adjust after KPADSetPosPlayMode has been
decided (Tight vs Loose)
3D Pointing:
Distance/Twisting/Gestures
•
Distance
–
Absolute distance can be computed
•
But only use relative distance
–
Could use distance to zoom
–
Smooth with KPADSetDistParam()
•
Twisting
–
Smooth with KPADSetHoriParam()
–
Could also use accelerometer
•
Gestures
–
Drawing symbols for spell casting
–
Use directional flicks to augment actions
