MindSpeller: Communicate Your Thought

Using a cap with several electrodes attached to it, Mindspeller captures the EEG signals. The cap, portable and not bigger than a matchbox, contains imec and Holst Centre’s proprietary ultra-low power 8-channel EEG-chip to process the EEG signals. A microcontroller installed inside digitizes these signals while a low power 2.4GHz radio wirelessly transmits the same to a PC places somewhere in vicinity. Powerful and robust signal processing algorithms have been developed by the team of Prof. Marc Van Hulle at the lab of neuro- and psychophysiology of the Katholieke Universiteit Leuven, using which the data is interpreted by the PC in a powerfull and efficient manner.
