An empirical comparison of "wiimote" gun attachments for pointing tasks
Victoria McArthur, Steven J. Castellucci, Ian Scott MacKenzie · 2009
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. The Wiimote communicates with the console via Bluetooth and an infrared sensor bar placed above or below the display. The sensor bar provides two points of infrared light, which are detected by the high-speed infrared camera on the Wiimote and are used to determine where the device is pointing. It also sports a three-axis linear accelerometer that provides the Wiimote with motion-sensing capabilities [10].
