VOICE-GUIDED WHEEL CHAIR CONTROL FOR INDIVIDUALS WITH IMPAIRMENTS

Abstract: One cutting-edge assistive technology designed specifically for people with physical limitations is the voice guided wheelchair. It works by processing voice commands sent by a mobile device with Bluetooth capability, which is handled by an Arduino BT Voice Operate module. This module converts the spoken commands into strings that can be used to move the wheelchair. It then relays this information to a Bluetooth Module SR-04 that is connected to an Arduino board. User-friendly commands like "Proceed," "Reverse," "Turn Left," "Turn Right," and "Halt" enable wheelchair users to move in a variety of directions with ease. With the use of this voice interface, wheelchair users with physical limitations can now be more independent and accessible than ever before. In addition, the wheelchair has an ultrasonic sensor to identify possible obstructions in front of it, allowing for safe travel and collision avoidance. The system enhances users' mobility independence and spatial awareness by incorporating this feature. The "Voice-guided Wheelchair" is essentially a revolutionary solution that empowers people with physical limitations by offering a low-cost, efficient, and user-focused mobility device that promotes autonomy and improves their quality of life.
