Navigation – Task Completion Time

Navigation - Error

Posture – Task Completion Time Significant Technique X Posture Interaction The task completion time with each technique varies depending on the posture or vice versa.

Posture – Task Completion Time

Posture - Error Wiimote/Nunchuk: M = 0 vs Keypad: M = 1.5

Wiimote/Nunchuk: M = 0

vs

Keypad: M = 1.5

Users’ Preferences

Participants completed both tasks faster and made fewer errors with the Wiimote/Nunchuk technique Participants prefer the Wiimote/Nunchuk technique overall Summary
