DESCRIPTION (provided by applicant): Physically disabled computer users unable to accurately control a mouse or other pointer cannot perform routine computer operations and cannot fully exploit many assistive software programs such as on-screen keyboards and speech augmentation programs. Such users often must use scanning input strategies (e.g., waiting for an option to be presented and then using a switch to select it). While recent advances have improved accessibility and speed for persons using scanning, it remains a very slow and tedious method. Operating a conventional pointer requires the user to concurrently control the cursor's location in two independent dimensions. The proposed research includes two experiments designed to determine the usefulness and feasibility of developing a pointing strategy that conceptually and functionally falls between operating a pointer and operating a single switch. Specifically, it is proposed that there are disabled users who could operate and benefit from a single dimensional pointing interface, especially when operation of that pointer is controlled by a behavior known to compliment the user's abilities. Such an interface also provides an opportunity to search for a variety of new input behaviors including novel motor responses and behaviors not directly observable (e.g., as measured by EEG, EMG, and other electrophysiological transducers).

描述（由申请人提供）：无法准确控制鼠标或其他指针的物理残障的计算机用户无法执行常规计算机操作，并且无法完全利用许多辅助软件程序，例如屏幕上的键盘和语音增强程序。这样的用户通常必须使用扫描输入策略（例如，等待显示选项，然后使用开关选择它）。尽管最近的进步提高了使用扫描的人的可访问性和速度，但它仍然是一种非常缓慢且乏味的方法。操作传统指针需要用户在两个独立的维度上同时控制光标的位置。拟议的研究包括两个实验，旨在确定制定指向策略的有用性和可行性，该策略在概念上和功能上均介于操作指针和操作单个开关之间。具体而言，建议有一些残疾用户可以从单个维指向接口中操作并受益，尤其是当该指针的操作受到已知的称赞用户能力的行为而进行的操作时。这样的界面还提供了一个机会，可以搜索各种新的输入行为，包括不直接观察到的新型运动响应和行为（例如，通过EEG，EMG和其他电生理传感器测量）。
