WASHINGTON (Reuters) - A new device that uses a tiny magnet can help disabled people steer a wheelchair or operate a computer using only the tip of the tongue, U.S. researchers reported on Monday.

The magnet, the size of a grain of rice, lets people direct the movement of a cursor across a computer screen or a powered wheelchair around a room.
