-------- PROTOTYPE --------- PURPOSE: To create a prototype of a communication tool that can be used by individuals with motoric disabilities (i.e. brain paralysis or speech or language disorders) to communicate. Developed by Belgian researchers from the European nanoelectronics and nano-technology research center, Imec, Holst Center, and Katholieke Universiteit in Leuven; the Mind Speller is a portable, easy-to-wear, intelligent textual and verbal communications prototype device based on an EEG-based writing system. Using EEG technologies the Mind Speller interprets brain waves to spell words and phrases. It detects and interprets P300 event-related potentials in the EEG-signals of a person that is selecting characters from a display presenting alternate rows and columns of characters. P300 potentials are often used as metrics of cognitive function in decision making processes. However, currently available P300 devices are large, expensive and uncomfortable in use. The Mind Speller, on the other hand, uses a portable device, not larger than a matchbox, connected to a cap that contains electrodes located at specific positions on the head to capture the relevant EEG-signals. The electronics in the matchbox are developed by the Imec and Holst Centre. It contains Imec and Holst Centre’s proprietary ultra-low power 8-channel EEG-chip to process the EEG signals, a commercially available low power microcontroller that digitizes the EEG signals and a low power 2.4GHz radio that transmits the EEG signals wirelessly to a nearby PC. The data is interpreted on the PC by powerful and robust signal processing algorithms developed by the team of Prof. Marc Van Hulle at the lab of neuro- and psychophysiology of the Katholieke Universiteit Leuven. Furthermore the Mind Speller is a generic device that be adjusted for different users. Therefore, making it a cost-efficient communication solutions with temporal impairments for whom existing solutions are cost prohibitive. TITLE: Mind Speller Lets Users Communicate with Thought.
