User Study• 8 Participants for Pilot Study

• 20 Participants (Mean = 22 yrs)

• 14 people either haven’t played the Wii before or played only a few times.

• Order:Wiimote -> Keypad (10 Participants)Keypad -> Wiimote (10 Participants)

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

Users’ Preferences

• Participants completed both tasks faster and made fewer errors with the Wiimote/Nunchuk technique

• Participants prefer the Wiimote/Nunchuk technique overall
