Practical Eye Tracking for Accessing Assistive Devices

描述(申请人提供)：这项研究的目的是确定一种独特的眼球跟踪概念用于控制辅助设备的可行性。这种访问方法可以特别容忍头部移动，并且理论上可以确定眼睛在计算机显示器上的目标位置在+/-0.3英寸以内。它不需要将活动设备装载到用户。 该系统结合了独特的隐形眼镜和红外跟踪系统来测量一个人正在看的地方。这种数学方法在计算上简单而高效，为该系统为目标人群合理定价打开了可能性。 拟议的眼球跟踪系统是专门为满足目前很少或没有访问选择的人的技术访问需求而设计的，例如患有高度脊髓损伤、脑干中风或处于退行性疾病(如肌萎缩侧索硬化症)晚期的人。这是通过开发一种价格合理、实用的用于增强通信设备、环境控制单元和计算机的眼睛控制访问方法来实现的

DESCRIPTION (provided by applicant): The purpose of this research is to determine the feasibility of a unique eye-tracking concept for controlling assistive devices. This access method may be exceptionally tolerant of head movement and can theoretically determine where the eye is targeted on a computer display to within +/- 0.3 inches. It does not require active devices to be mounted to the user. The system combines a unique contact lens and infrared tracking system to measure where a person is looking. The mathematical approach is computationally simple and efficient, opening the possibility that the system will be reasonably priced for the target population. The proposed eye-tracking system is specifically designed to meet the technology access needs of persons who presently have few or no access options, such as individuals with high spinal-cord injuries, brainstem strokes, or those who are in the late stages of degenerative diseases such as amyotrophic lateral sclerosis. This is accomplished by developing a reasonably priced, practical eye-controlled access method for augmentative communication devices, environmental control units, and computers
