Tongue-Joystick Hybrid Control for Enhanced Wheelchair Mobility

Abstract

This paper explores how a human tongue can provide a solution for those with tetraplegia by assisting in independently operating a wheelchair. Tetraplegia is a condition in which the sensory organs within the four limbs are dysfunctional, making daily tasks, such as operating a wheelchair, extremely challenging for those affected. To address this challenge, we have designed a wearable mouth set that consists of Hall Effect sensors and magnets. The tongue is used to apply pressure to a specific region of the cheek, where the magnet is located, to control the wheelchair using the Hall Effect sensor. This methodology provides a simple and efficient way to address the mobility issues associated with tetraplegia. In addition, the use of ultrasonic sensors further enhances the wheelchair operation, allowing the user to detect obstacles in the path. These sensors play a critical role in the user, allowing them to make informed decisions and navigate barriers safely. The device provides a means of controlling a wheelchair through an intuitive and natural mechanism, which eliminates the need for more complicated interfaces, further simplifying the user experience. For individuals with specific physical restrictions that prevent them from using the tongue-controlled mode, there's an alternative option available in the form of joystick control.
