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）：该项目旨在改善生活质量，计算机可访问性和脊髓损伤（SCI）和其他无法使用标准计算机键盘和鼠标的个人的就业潜力。一些辅助产品，如头部跟踪器，适合控制鼠标指针的位置。然而，大多数这样的指向产品不提供用于创建鼠标点击的不显眼或有效的手段。第一阶段SBIR项目开发了一个概念验证单元，可以检测用户的嘴或嘴唇做出的细微手势，并将其解释为鼠标点击或其他类型的开关输出，为许多用户需求提供快速有效的解决方案。在第二阶段，我们计划：a）基于来自残疾人、治疗师、技术专家和潜在雇主的输入，细化对原型“唇阅读”设备的要求，B）将感测装置升级为更紧凑、易于由用户或护理者安装，并且甚至不需要定位在用户上，c）升级信号处理和模式识别算法，以便为那些有语言或相关运动控制问题的人提供对无意手势的额外拒绝，以及e）进行短期用户评估和为期一个月的家庭试用，以展示该项目的主要创新。其结果将是，在第二阶段结束时，我们有一个原型“唇阅读”设备，具有高品质的外观，感觉，和功能，沿着与测试数据，从用户显示有用和有效的性能，以及高度的用户满意度和偏好的产品。 公共卫生关系：这项SBIR项目第二阶段的研发工作将为无法使用标准鼠标点击计算机屏幕上的对象的残疾人提供更好的使用计算机的方法。该技术还将为非计算机应用提供改进的开关设备。该项目的成果将使这些人能够提高生产力，从而提供更好的就业潜力和提高生活质量。
