Abstract

The work presented reports on the development of a data acquisition system intended to be used in Human-Computer-interfacing applications to synchronously record upper limb movement and corresponding biosignals, be it EEG, ECoG, EMG or multi unit neuronal signals. Ultimately, this aims at the clinical recording of ECoG signals from awake patients undergoing tumor resection. For that purpose stereo-video camera frames are used to detect and triangulate hand and finger positions with high precision while at the same time a DSP-based 32-channel board acquires wideband biosignals. We validated the synchronous acquistion of both space coordinates and bioelectrical signals (EMG) by performing simple grasp experiments. Further research will be dedicated to the system's clinical application.
