The document describes a tongue drive system, which is an inductive tongue-computer interface designed to help people with spinal cord injuries control their environment. It works by attaching a tiny magnet to the tongue, which is detected by sensors and used to control a computer cursor or powered wheelchair. The system takes advantage of the direct connection between the tongue and brain without needing hands or legs. The newer version is smaller, wireless, and can recharge, allowing for control of assistive devices with quick tongue movements. The tongue drive system aims to improve independence and quality of life for users.
