Studies (3)

As It was expected, other people also tried to interface the Wiimote with Matlab. Interesting to discover their work and to think about our common ideas and our encountered troubles, extrapolations and limitations of the wiimote as a "engineered device" :

Summary

Virtual reality (VR) gaming environment as a tool for rehabilitation of patients with upper extremity disorders is fast gaining momentum. VR based motor training systems provide an engaging, motivating and adaptable environment where the motion of the limb displayed in the virtual world is a replication of the motion produced in the real world by the patient’s extremity.
The goal of this thesis was to create a generic gaming system which can be interfaced to a number of different Human interface devices (HID) and produce rich graphics to create a virtual environment which closely resembles the real world. This would overcome the current limitations of the ‘HANDS UP’ game developed by the Neuromuscular lab which accepts only a web camera input and uses color marker detection to recreate the limb movements in simple two dimensional environment.
Three dimensional worlds designed in Virtual Reality Modeling Language (VRML) were controlled using SIMROBOT and Virtual reality toolbox in MATLAB to create better visualization. The Human Interface devices currently used for Virtual Reality video games are expensive and cannot be used for home use. Various new HID’s like the Flock of Birds® from Ascension, Nintendo Wiimote and IMU 6 DOF V3 were tested for their use in the virtual gaming environment. Each device presented their own set of advantages and problems. The thesis work involved understanding and resolving these problems and interfacing the devices with the gaming system.

A M-file and a DLL are available for testing Matlab with the Wiimote. The file wii_data_acquisition.m provides plots from the accelerometer.

Comment

Kunal J. Doshi is what I must call a "peer" in learning and developing applications with Matlab and the wiimote.
Indeed, by following the same way as the project fwiine, he succeeded in developing his own mex-command, earlier. Moreover, he made a great overview of similar devices to the wiimote for biomedical purposes.

Summary

This is a bachelor project at the Department of Computer Science at the University of Fribourg, Swiss.

It was asked for students to conceive a multimodal application. The aim of the team was to develop an intuitive and multimodal device which was collecting voice and wiimote features. The report describes the application features and the basis for this development. Then the program can handle video and audio files.
