Translating a desired user's input using conventional methods such as a keyboard and mouse for the computer, or a joystick for a wheelchair is a major challenge faced by users whom have no limb control. This paper describes an iteration of Resistopalatography, a method using the tongue as a pointing device to emulate the use of the hand for cursor movement and wheelchair control. The system employs force sensitive sensors located within the mouth on a dental retainer plate to measure the tongue's pressure against the hard palate. The position and force of tongue against the sensors can be translated into mouse cursor or wheelchair joystick equivalents.
对于没有肢体控制能力的用户而言，使用诸如计算机键盘和鼠标这类传统方法，或者轮椅操纵杆来翻译期望的用户输入是一项重大挑战。本文描述了电阻式腭描记法的一次迭代，该方法利用舌头作为指向设备来模拟用手进行光标移动和轮椅控制。该系统在牙托板上的口腔内设置了力敏传感器，以测量舌头对硬腭的压力。舌头相对于传感器的位置和压力可被转换为等效的鼠标光标或轮椅操纵杆指令。
