Wiimote and latest Human Computer Interfaces - efficiency and robustness

[English Version]

While Human Computer Interfaces are becoming popular ( multitouch tactile display, 3D vision device,...), several studies underlined their constraints and limitations in term of efficiency.

Obviously, some usual devices will not disappear but the latest 3D peripherals will challenge the well-established ones (such as mouse or keyboard) for innovative applications.

(Extract : Researchers are recognizing the potential of position sensors to help them overcome the limitations of traditional user interfaces.)

Here, many wiimote-based applications tackle the problem of robustness and accuracy, too. (in term of IR tracking error, accelerometer bandwidth, etc).

Finally, the last chapters of this post give an overview of novel usages. Focusing on the use of wiimote as a scientific sensor, some behavioral studies and other hardwares customization will be presented.

1. Accuracy of IR sensor for tracking algorithms

Now, reaching accuracy of 2.233mm with 2 wiimotes :

2. Frequency range

Extract from the abstract (file is not freely available - property and courtesy of US National Library of medicine):
"This system using a Wii Remote is capable of analyzing frequency and estimated amplitude of tremor between 3 Hz and 15 Hz. ... The acceleration data is sampled with about 30msec. After the measurement ends, a power spectral density (Fast Fourier transform method) and peak frequencies are presented.The frequency element that can be measured with this system is 15 Hz or less. Since the frequency elementsof tremor are estimated to be 12 Hz or less, the tremor frequency analysis using this system is applicable."
