Intelligent Control Systems for Physically Disabled and Elderly People for Indoor Navigation
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 9
Abstract
The needs of many individuals with disabilities can be satisfied with traditional manual or powered wheelchairs, a segment of the disabled community finds it difficult or impossible to use wheelchairs. There is extensive research on computer controlled chairs where sensors and intelligent control algorithms have been used to minimize the level of human intervention. This paper describes a wheelchair for physically disabled people. This paper is to describe an intelligent powered wheelchair for handicapped person using voice signal, touch screen, ultrasonic and infrared sensor system which are interfaced with motors through microcontroller. When we want to change the direction, the touch screen sensor is modelled to direct the user to required destination using direction keys on the screen and that values are given to microcontroller. Depending on the direction selected on the touch screen, microcontroller controls the wheelchair directions. This can be controlled through the voice commands. The speech recognition system is easy to use programmable circuit that to be restored with the words which needs the circuit to be recognized. Possibility of avoiding obstacles by using ultrasonic sensors, downstairs or hole detection by using infrared sensors.
