Now Wheelchairs, Computers etc can be operated by tongue

आत्मीय मित्रो,
अब जीभ से कम्प्यूटर, व्हील चेयर चलाना सम्भव है.  ऐसा जीभ में एक छोटा चावल के दाने के बराबर का चुम्बक लगाने से सम्भव हो सका है. अमेरिका में हुयी इस रिसर्च के अनुसार जीभ का कंट्रोल सीधा मस्तिस्क से होता है और स्पाइनल इंजुरी में अक्सर यह प्रभावित नहीं होती है.

आपकी जानकारी के लिए एक ऐसी ही ख़बर नीचे संलग्न है. आशा है इसे पढ़ कर आप का ज्ञानवर्धन होगा.

Now disabled could operate wheelchairs, computers with tongue
Washington, June 30 (IANS) People with severe disabilities will soon be able to operate a computer or control a powered wheelchair simply by moving their tongues, thanks to a new magnetic device.

This device could help individuals ‘with high-level spinal cord injuries, return to rich, active, independent and productive lives’, said Maysam Ghovanloo of Georgia Tech School who developed the new system with graduate student Xueliang Huo. 

A small magnet as small as a grain of rice is implanted in an individual’s tongue and allows it to direct the movement of a cursor across a computer screen or a powered wheelchair around a room.

‘We chose the tongue to operate the system because unlike hands and feet, which are controlled by the brain through the spinal cord, the tongue is directly connected to the brain by a cranial nerve that generally escapes damage in severe spinal cord injuries or neuromuscular diseases,’ said Ghovanloo.

He started working on this project about three years ago at North Carolina State University. ‘Tongue movements are also fast, accurate and do not require much thinking, concentration or effort,’ he added.

Movement of the magnetic tracer attached to the tongue is detected by an array of magnetic field sensors mounted on a headset outside the mouth or on an orthodontic brace inside the mouth. The sensor output signals are wirelessly transmitted to a portable computer, which can be carried on the user’s clothing or wheelchair.

The system can potentially capture a large number of tongue movements, each of which can represent a different user command. A unique set of specific tongue movements can be tailored for each individual based on the user’s abilities, oral anatomy, personal preferences and lifestyle.

‘An individual could potentially train our system to recognise touching each tooth as a different command,’ explained Ghovanloo.

Ghovanloo’s group recently completed trials in which six able-bodied individuals tested the system. Each participant defined six tongue commands that would substitute forcomputer mouse tasks – left, right, up and down pointer movements and single- and double-click.

Results of the computer access test by novice users showed a response time of less than one second with almost 100 percent accuracy for the six individual commands.

The technique was presented Sunday at the annual conference of Rehabilitation Engineering and Assistive Technology Society of North America (RESNA).
