A paralysed man with motor neurone disease is helping scientists build a mind reading machine to help him and other patients to communicate. The low cost prototype enables patients to make their wishes known to doctors and their loved ones on a very simple level. Tom Chen is now almost entirely confined to bed. He has motor neurone disease also known as Amyotrophic lateral sclerosis. The disease progressively damages the nervous system and Chen is almost at the stage where he is unable to communicate with wife Kiki Qu or with doctors. Chen’s wife is helping him test out new software developed at National Taipei University of Technology.
