为了支持上肢残疾卧床不起的人进行自然交流，我们提出了一种免提指向系统，可以无缝指示电脑和真实物体。作者通常开发的“气枕界面”可以测量头部运动来控制电脑显示器上的光标，并可以同时控制用户头部附近云台执行器上激光指示器的方向。用户通过头部运动界面移动光标，当光标到达显示屏末端时，光标会以激光束的形式跳出到现实世界。我们通过实验证实了所提出方法的有效性，并通过 PC 和真实物体的指向能力的吞吐量值来评估操作性能。
To support natural communication by bedridden persons with upper limb disabilities, we propose a hands-free pointing system that enables seamless indication of PC and real objects. An “air-pillow interface,” conventionally developed by the authors, can measure head motions to control a cursor on a PC display and can simultaneously control the direction of a laser pointer on a pan-tilt actuator near the user’s head. The user moves the cursor with the head motion interface, and when the cursor reaches the end of the display, the cursor will jump out to the real world as a laser beam. We experimentally confirm the validity of the proposed method and evaluate the operating performance by throughput values with regard to pointing ability for PC and real objects.
