Information

Its purpose is to reduce or eliminate the users task of driving a motorized wheelchair. Usually, a smart wheelchair is controlled by a computer, has a suite of sensors and applies techniques in mobile robotics, but this is not necessary. The interface may consist of a conventional wheelchair joystick , or it may be a "sip-and-puff" device or a touch-sensitive display connected to a computer. This is different from a conventional motorized or electric wheelchair, in which the user exerts manual control over motor speed and direction via a joystick or other switch- or potentiometer-based device, without intervention by the wheelchairs control system.
