Smart Voice and Gesture Controlled Wheel Chair

Abstract

Recently, various smart devices are available on the market to assist physically impaired people. However, there are significant limitations in existing devices, such as the fact that they are expensive and cannot be purchased by the general public. Additionally, the existing wheelchairs are heavy and are difficult to manually push it from one place to another place. To overcome the aforementioned challenge, this research study has nronosed a smart voice and gesture controlled wheel chair. The wheel chair will be operated either with hand/finger/elbow/leg/head gesture or by voice command by employing a voice recognition module VR3 along with Arduino UNO. Followed by an extensive research study, this technology remains underutilized in the local market, either due to cost or due to hardware problems. The proposed prototype will be extremely beneficial to physically impaired people since they would be able to operate the wheelchair by just moving their fingers, hands, or other body parts. Depending on the direction of the acceleration or voice command like LEFT, RIGHT, FRONT, and BACK, the wheel chair directions can be changed. This can be controlled by using a microcontroller. This type of wheel chair will help in transferring the physically disabled person one place to another. The user can control the wheel chair by using either hand gesture or voice. From the results, it is evident that the proposed research study has successfully developed a cost-effective smart gesture and voice command controlled wheel chair.
