This abstract provides a concise overview of mobile-based and voice controller-based wheelchairs, two innovative assistive technologies designed to enhance mobility and independence for disabled individuals. These systems utilize mobile applications and voice recognition techniques, respectively, to facilitate intuitive wheelchair control and navigation. The mobile-based wheelchair system incorporates a mobile application installed on a smartphone or tablet. The instructions are communicated to the wheelchair control system, enabling users to maneuver their wheelchairs using visual and auditory cues provided by the application. In the voice controller-based wheelchair system, voice recognition technology is employed to interpret spoken commands from the user. Advanced algorithms analyze and process these commands, allowing the system to recognize and respond to specific voice prompts. The wheelchair control module translates these commands into appropriate motorized movements, enabling users to control their wheelchairs through natural voice instructions. Both mobile-based and voice controller-based wheelchairs offer distinct advantages to disabled individuals. The mobile-based system provides flexibility, as it can be used with a range of mobile devices and offers customizable settings for route selection and accessibility preferences. The voice controller-based system offers an intuitive and hands-free control interface, reducing physical exertion and allowing for effortless wheelchair navigation. These assistive technologies significantly enhance the mobility and independence of disabled individuals. By eliminating the need for manual controls, individuals with limited physical capabilities can operate their wheelchairs more efficiently. Both systems prioritize user safety, incorporating collision detection mechanisms and obstacle avoidance features.
