VOICE CONTROLLED AND TFT TOUCHSCREEN CONTROLLED WHEELCHAIR

Abstract

In today’s world, widespread prevalence of lost limbs and sensing system is of major concern in present day due to accident, age and health problems. To assist people with such defects, the proposed intelligent wheelchair system is used which have dual control for navigation in familiar environments. This paper is related to voice command and touchscreen display based model of a wheelchair. The smart wheelchair system used the voice recognition module V3 and a 2.8” TFT Touchscreen display. Wheelchair is facilitating the movement of people who are disabled or handicapped and elderly people. The wheelchair design will allow people to do their basic daily tasks without any dependence on other person. In building the circuit for this project, we are using AURDINO MEGA and its interfacing with TFT Touchscreen module and voice recognition module with direct current motors for movement of wheelchair in different directions. The system has been designed and implemented in a cost-effective way so that if our project is commercialized the needy users in developing countries will benefit from it.
