An empirical comparison of "wiimote" gun attachments for pointing tasks

We evaluated and compared four input methods using the Nintendo Wii Remote for pointing tasks. The methods used (i) the "A" button on top of the device, (ii) the "B" button on the bottom of the device, (iii) the Intec Wii Combat Shooter attachment and (iv) the Nintendo Wii Zapper attachment. Fitts' throughput for all four input methods was calculated for both button-up and button-down events. Results indicate that the throughput of the Wii Remote using the A button is 2.85 bps for button-down events. Performance with the Intec Wii Combat Shooter attachment was significantly worse than with the other input methods, likely due to the trigger mechanism. Throughput for button-down target selection using the B button was highest at 2.93 bps.
