Alternative and effective methods for controlling powered wheelchairs are important to individuals with tetraplegia and similar impairments whom are unable to use the standard joystick. This paper describes a system where tongue movements are used to control a powered wheelchair thus providing users, with high level spinal cord injuries, full control of their wheelchair. The system is based on an inductive tongue control system developed at Center for Sensory-Motor Interaction (SMI), Aalborg University. The system emulates a standard analog joystick in order to interface the wheelchair, thus ensuring that the system works with almost any wheelchair. The total embedment of the tongue interface into the mouth makes the control practically invisible. A fuzzy system combining 8 sensors for directional control allows for multidirectional control of the wheelchair. Preliminary test results show navigation abilities, which are highly competitive when compared to other tongue control system.
对于四肢瘫痪及类似损伤且无法使用标准操纵杆的个体而言，控制电动轮椅的替代有效方法至关重要。本文描述了一种利用舌头运动来控制电动轮椅的系统，从而为高位脊髓损伤的用户提供对其轮椅的完全控制。该系统基于奥尔堡大学感觉运动交互中心（SMI）开发的感应式舌头控制系统。该系统模拟标准模拟操纵杆以便与轮椅连接，从而确保该系统可与几乎任何轮椅配合使用。舌头接口完全嵌入口腔使得控制几乎不可见。一个结合8个用于方向控制传感器的模糊系统允许对轮椅进行多方向控制。初步测试结果显示出导航能力，与其他舌头控制系统相比具有很强的竞争力。
