It sounds a bit scary but actually there lots of "good" applications to it. NeuroSky is a biosensor company that builds sensors and a signal processing system to read and translate brain and muscle waves into digital signals that in turn can be used to interact with PCs (to move objects on the screen, recreate the face movement, play video games...), automotive (e.g. to detect drowsiness), cell phones (for games), MP3 players that will select music based on your mood! The San Jose company expects products (headsets primarily) using its sensors to appear in retail by mid-next year.
Although there other companies in the field, like Emotiv Systems or CyberLearning Technology, NeuroSky claims to have the easiest and the more consumer friendly solution with very small sensors. At the next Game Developer Conference in San Francisco, Neurosky will show off a headset coupled with an action video game that will let gamers move and shoot without a keyboard or a mouse. Something that Emotiv already has but with a bulkier headset. Interview of NeuroSky CEO Stanley Yang after the jump.
