已经为诸如ALS患者的严重身体残疾的人开发了许多辅助通信的系统。眼睛注视输入系统目前正在评估作为一种新的接口，它可以用来操作计算机的眼睛运动。大多数传统的眼睛注视输入系统使用眼睛上的红外线来检测眼睛注视。然而，长时间的照射可能会损害眼睛。本文提出了一种新的眼睛注视输入系统，利用个人计算机和家庭摄像机检测自然光下的眼睛注视多指标。它通过简单的图像分析来检测垂直和水平的眼睛注视，并且不需要特殊的图像处理单元或传感器。它还补偿了由头部移动引起的测量误差，即，它能够以高精度检测眼睛注视。因此，它能够区分多种指标，其应用有望扩大。
Many systems to aid communication have been developed for seriously physically handicapped people such as ALS patients. The eye-gaze input system is currently being evaluated as a novel interface; it can be used to operate a computer with eye movement only. Most conventional eye-gaze input systems use of an infrared ray on the eyes to detect eye-gaze. However, prolonged irradiation could damage the eyes. This paper proposes a new eye-gaze input system with multi-indicators utilizing a personal computer and a home video camera to detect eye-gaze under natural light. It detects both vertical and horizontal eye-gaze through simple image analysis, and does not require special image processing units or sensors. It also compensates for measurement errors caused by head movement, i.e., it can detect eye-gaze with a high degree of accuracy. Therefore, it is capable distinguishing many indicators and its applications are expected to be expanded.
