DESCRIPTION (provided by applicant): For those with high-level physical disabilities, communication, a very fundamental and essential need, is challenging. For many it can even be frightening if they have no way to express their most basic personal and medical requirements. For those with Locked-in -Syndrome (LIS) and those in the advanced stages of Amyotrophic Lateral Sclerosis (ALS), for example, eye movement is often the only communication alternative. These users cannot control a computer or augmentative and alternative communication (AAC) device by other means including any other type of physical motion or speech. The provision of a repeatable user and caregiver friendly eye-tracking device therefore becomes of paramount importance. The proposed project aims to develop a dramatically improved eye-activated communication device for this user population. While the current VisionKey(tm) works well for many users who utilize the system for up to ten hours a day, there are several key enhancements necessary to add to the user's comfort; ease of use, set up and calibration; and functionality. The key areas of improvement are: ergonomic refinement, adjustability, adaptability, user-friendliness and icon-based capability. The objective of the final product is to provide an eye-activated device which offers dynamic, adjustable, handsfree communication for both AAC and full computer control purposes. The proposed device is based on the patented VisionKey eye-tracking input device from H.K. Eyecan Ltd. integrated with The MicroOptical Corporation's patented eyeglass-based display technology. The new device will be ergonomically superior to the current VisionKey product, and, most significantly, will incorporate a dynamically refreshable electronic display. The dynamic display allows the available selections to be modified in real time to reflect the current context, thereby, simplifying the use of the device and improving speed and accuracy. The new device will also offer an opportunity to incorporate a larger set of selections and make possible the use of icons in addition to the current text-based selection set. This coupled with the reduced cognitive load will make the device suitable to provide a communication alternative for a much larger target user community including pre-literate children and/or individuals with cognitive, language and developmental disabilities.

描述（由申请人提供）：对于那些患有严重身体残疾的人来说，沟通是一项非常基本和必要的需求，但具有挑战性。对于许多人来说，如果他们无法表达最基本的个人和医疗需求，甚至会感到恐惧。例如，对于患有锁定综合症 (LIS) 和肌萎缩侧索硬化症 (ALS) 晚期的人来说，眼球运动通常是唯一的交流选择。这些用户无法通过其他方式（包括任何其他类型的物理运动或语音）控制计算机或增强和替代通信 (AAC) 设备。因此，提供可重复的用户和护理人员友好的眼睛跟踪设备变得至关重要。该项目旨在为该用户群开发一种显着改进的眼动通信设备。虽然当前的 VisionKey(tm) 对于许多每天使用该系统长达 10 个小时的用户来说效果很好，但为了增加用户的舒适度，还需要进行一些关键的增强；易于使用、设置和校准；和功能。改进的关键领域是：人体工程学改进、可调节性、适应性、用户友好性和基于图标的功能。最终产品的目标是提供一种眼动设备，为 AAC 和全计算机控制目的提供动态、可调节、免提通信。 该设备基于 H.K. 获得专利的 VisionKey 眼球追踪输入设备。 Eyecan Ltd. 集成了 MicroOptical Corporation 的基于眼镜的专利显示技术。新设备在人体工程学方面将优于当前的 VisionKey 产品，最重要的是，它将采用动态可刷新的电子显示屏。动态显示允许实时修改可用选择以反映当前上下文，从而简化设备的使用并提高速度和准确性。新设备还将提供合并更大的选择集的机会，并且除了当前基于文本的选择集之外还可以使用图标。再加上认知负荷的减少，将使该设备适合为更大的目标用户社区提供通信替代方案，包括识字前的儿童和/或有认知、语言和发育障碍的个人。
