Hand-Gesture Technologies Wave Bye to Desktop Mouse
BY JESSICA E. VASCELLARO A race to liberate computer users from the mouse is kicking into high gear, inspired by the potential of turning hands and other body parts into digital controllers.
The goal: to manage computers and other devices with gestures rather than pointing and clicking a mouse or touching a display directly. Backers believe that the approach can make it not only easier to carry out many existing chores but also take on trickier tasks such as creating 3-D models, verifying whether clothes fit, training athletes and browsing medical imagery during surgery without touching anything.

Robot arm runs on brain power
Cathy, who was completely
paralysed by a stroke 15 years ago, thought about having a drink of
coffee. A robotic arm responded by moving her drinking bottle from a
nearby table up to her mouth so she could sip through the straw.
The remarkable experiment in brain technology was the first time
since the stroke that 58-year-old Cathy had drunk without help from a
carer. “The smile on her face was a remarkable thing to see,” said Leigh
Hochberg, a professor of neuro-engineering at Brown University in Rhode
Island.Cathy was one of two tetraplegic patients taking part in a clinical trial of the BrainGate brain-computer interface developed at Brown.
The results, reported in tomorrow’s edition of the journal Nature, describe the most complex functions anyone has performed using a brain-computer interface.
“Years after the onset of paralysis, we found that it was still possible to record brain signals that carry multi-dimensional information about movement and that those signals could be used to move an external device,” Prof Hochberg said.
The researchers say their technology is still several years from practical use. The future lies in developing a fully automated, wireless brain-computer interface.
