DESCRIPTION (provided by applicant): This project aims to improve the quality of life, computer accessibility, and employment potential for spinal cord injured (SCI) and other individuals who cannot use a standard computer keyboard and mouse. Some assistive products, such as head trackers, are suitable for controlling the position of the mouse pointer. However, most such pointing products do not provide an unobtrusive or efficient means for creating mouse clicks. The Phase I SBIR project developed a proof of concept unit that can detect subtle gestures made by the mouth or lips of the user, and interpret these as mouse clicks or other types of switch output, providing a quick and efficient solution to many user needs. In Phase II, we plan to: a) Refine the requirements for the prototype "lip reading" device, based on inputs from people with disability, therapists, technologists, and potential employers, b) Upgrade the sensing apparatus to be more compact, easily mountable by users or caregivers, and even less needful of positioning on the user, c) Upgrade the signal processing and pattern-recognition algorithms to provide additional rejection of unintentional gestures for those with speech or related motor-control issues, d) Create driver and user preference software for the PC, and e) Perform a short-term user evaluation and a month-long in-home trial that demonstrates the main innovations of the project. The result will be that at the end of Phase II, we have a prototype "lip reading" device that has a high-quality look, feel, and function, along with test data from users that shows useful and efficient performance, and a high degree of user satisfaction and preference for the product. PUBLIC HEALTH RELEVANCE: The R&D in this Phase II SBIR project will result in an improved way to use computers for individuals with disabilities who cannot use a standard mouse to click on objects on the computer screen. The technology will also provide an improved switch device for non-computer applications. The results of the project will enable such individuals to be more productive, thus providing improved employment potential and an increase in the quality of life.

描述（由申请人提供）：该项目旨在提高脊髓受伤（SCI）（SCI）的生活质量，计算机可及性和就业潜力，以及其他无法使用标准计算机键盘和鼠标的人。一些辅助产品（例如头部跟踪器）适合控制鼠标指针的位置。但是，大多数这样的指向产品并未提供创建鼠标点击的不引人注目或有效的手段。 I阶段SBIR项目开发了概念验证单元，可以检测用户口腔或嘴唇制作的微妙手势，并将其解释为鼠标点击或其他类型的开关输出，从而为许多用户需求提供快速有效的解决方案。 In Phase II, we plan to: a) Refine the requirements for the prototype "lip reading" device, based on inputs from people with disability, therapists, technologists, and potential employers, b) Upgrade the sensing apparatus to be more compact, easily mountable by users or caregivers, and even less needful of positioning on the user, c) Upgrade the signal processing and pattern-recognition algorithms to provide additional rejection of对于那些有语音或相关电机控制问题的人的无意性手势，d）为PC创建驱动程序和用户偏好软件，e）执行短期用户评估和为期一个月的家庭试验，展示了该项目的主要创新。结果是，在第二阶段结束时，我们有一个原型的“唇读”设备，具有高质量的外观，感觉和功能，以及来自用户的测试数据，这些数据显示出有用和高效的性能，以及高度的用户满意度和对产品的偏好。 公共卫生相关性：此阶段II SBIR项目中的研发将导致改进的方法，用于使用无法使用标准鼠标单击计算机屏幕上的对象的残疾人使用计算机。该技术还将为非计算机应用提供改进的开关设备。该项目的结果将使此类人的生产力更高，从而提供了提高的就业潜力和生活质量的提高。
