Implementation of Electromyogram Interface in CABIN Immersive Multiscreen Display

The electromyogram (EMG) signal, which is a kind of biomedical information, might be promising as a computer-human interface. The purpose in this paper is to make a brief report on implementation of the EMG interface in CAVE-clone display and propose the advantages of it. In general, it is expected that the environmental electromagnetic noise would disturb the novel EMG signals. We measured the EMG signals and obtained high signal-to-noise ratio in CABIN immersive multiscreen display constructed at the University of Tokyo. The observed signal-tonoise ratio would make EMG signals a reliable input channel with simple signal processing, and real time control of virtual objects was successfully performed. The advantages of the EMG signals will be proposed as a promising human interface in immersive multiscreen environments. The user would control virtual objects reflecting the activations of the user’s muscles to realize fine operations. Furthermore, by using this additional biosignal channel, the user might interact with virtual objects without definite motion.
