Assistive Technologies for Man-Machine Interface and Applications in Education and Robotics

  This paper focuses on the current state of the art assistive technologies in man-machine interface, and its applications in education and rehabilitation robotics. We present here simple tasks based on structured lights with light spot configuration in 1-D and 2-D CCD or PSD arrays for student exercises in optoelectronics. Also presented are the following devises: Head joystick based on a set of instructions derived from intended head movement, automatic parking equipment for wheelchairs, the range-inclination tracer for wall-following and collision avoidance of wheelchairs, the body motion joystick based on a set of instructions derived from intended body motion sampled by a six component force-torque transducer inserted between the saddle and the chassis of the wheelchair, handy navigator for blind people, which consists of two pairs of laser diodes with light spot configuration sampled by the 1-D CCD array (alternatively PSD array), and microprocessor tuned pitch and timbre sound source for the representation of a 3-D objects articulation.
