Assistive Device for Differently Abled People

It is difficult to focus on and solve the issues experienced by persons with varied abilities, such as those who are visually, audibly, or vocally handicapped, using just one technology. Lastly, based on the Raspberry Pi microcontroller and a few more parts, this research proposes an assistive gadget for those who are blind, deaf, and dumb. Raspberry Pi as the main microcontroller, a touch screen display for being user friendly, a Bluetooth microphone that uses the voice bot app, an earphone for the voice output Pi camera for object detection, UART and HC 05 as Bluetooth modules, and an ultrasonic sensor for obstacle detection are all included in the system. We are mainly focusing on six important objectives in this paper which include: Speech to text, text-to-speech using Google API, image- to-speech, face recognition to save and recognize photographs of close relatives in both voice and text, obstacle detection, and gesture recognition are the device’s six main goals. The gadget is based on the Raspberry Pi and makes use of its capabilities and computing power. It also has a 3.5- inch touchscreen for user- friendliness. The system’s elements work together to produce a complete and simple aid for people with disabilities. The device’s performance, advantages, and possibilities for advancement in the future are all thoroughly examined.
