These two studies assessed camera-based microswitch technology for eyelid and mouth responses of two persons with profound multiple disabilities and minimal motor behavior. This technology, in contrast with the traditional optic microswitches used for those responses, did not require support frames on the participants' face but only small color marks. The person involved in Study I had previously used optic sensors fixed on an eyeglasses' frame for detecting his eyelid- and mouth-opening responses. However, a deterioration of his head posture was making the correct location/use of this frame progressively more difficult. The person involved in Study II had previously been selected for a program relying on eyelid-closure responses and an optic sensor. Such a program however appeared difficult to implement given his sideward lying position and dystonic head movements. The new technology could be satisfactorily applied with both participants using mouth and eyelid opening with the first participant and eyelid closures with the second participant. Both participants had large increases in responding during the intervention periods (i.e., when their responses were followed by preferred stimulation). The findings are discussed in relation to the role of the new technology in helping persons with multiple disabilities and minimal motor behavior.
这两项研究评估了基于摄像头的微开关技术，用于两名深度多重残疾且运动行为极少的患者的眼睑和嘴巴反应。与用于这些反应的传统光学微开关相比，这项技术不需要在参与者的脸上安装支撑框架，只需要小的彩色标记。研究 I 中涉及的患者之前曾使用固定在眼镜架上的光学传感器来检测他的眼睑和嘴巴张开反应。然而，他头部姿势的恶化使得正确定位/使用该框架变得越来越困难。研究 II 中涉及的患者之前曾被选择参加依赖于眼睑闭合反应和光学传感器的项目。然而，鉴于他侧向躺着的姿势和张力障碍性头部运动，该项目似乎难以实施。新技术可以通过第一个参与者的嘴巴和眼睑张开以及第二个参与者的眼睑闭合，满意地应用于两个参与者。两个参与者在干预期间的反应都有较大增加（即，当他们的反应后跟随有偏好刺激时）。研究结果结合新技术在帮助具有多重残疾和最小运动行为的患者方面的作用进行了讨论。
