Scientists Develop Brain-Computer Interface for Cellphones
Some San Diego researchers developed a system that allows users to dial a phone number on a cellphone using only their thoughts. The method is surprisingly accurate and would be a huge advantage for people with disabilities or anyone who needs a more hands-free experience or who regularly performs tasks that require a high degree of mental focus.
The technology, which wasÂ developed by University of California, San Diego neuroscience researcherÂ Tzyy-Ping Jung and colleagues, tracks electrical activity in the brain using a headband of electrodes and aÂ Bluetoothdevice. Users of the system were shown digits from zero to nine flashing at slightly different speeds on a computer screen; the frequency of each digit was detected by the electrodes, allowing the Bluetooth device to â€œknowâ€ which numbers to dial.
In various trials, subjects with varying degrees of training showed between 70% and 85% accuracy when attempting to dial a 10-digit phone number.
Computer-brain interfaces have been around for a while; this is the first instance weâ€™ve seen of a brain interface being applied to a mobile phone. Being able to make brain interfaces smaller, faster and cheaper might go a long way toward these novel technologies becoming more practical for everyday use for a mass audience.
personally that would drive me nuts, especially with ADD. Already difficult to get the phone to react correctly with fingers.
