目前用于患有ALS或其他运动障碍的人的眼睛跟踪输入系统是昂贵的，在阳光下不鲁棒，并且需要频繁的重新校准和大量的相对固定的设置。目光转移（e-tran）板是一种低技术含量的替代品，很难掌握，而且通信速率很慢。为了减轻这两种现状方法的缺点，我们创建了GazeSpeak，这是一种在智能手机上运行的眼球姿态通信系统，其设计成本低，功能强大，便携式，易于学习，具有比e-tran板更高的通信带宽。GazeSpeak可以在真实的时间内解释眼睛的手势，将这些手势解码成预测的话语，并促进交流，为演讲者和口译员提供不同的用户界面。我们的评估表明，GazeSpeak是强大的，具有良好的用户满意度，并提供了一个速度的改进，相对于电子交易板，我们还确定了进一步改进的途径，以低成本，低工作量的凝视为基础的通信技术。
Current eye-tracking input systems for people with ALS or other motor impairments are expensive, not robust under sunlight, and require frequent re-calibration and substantial, relatively immobile setups. Eye-gaze transfer (e-tran) boards, a low-tech alternative, are challenging to master and offer slow communication rates. To mitigate the drawbacks of these two status quo approaches, we created GazeSpeak, an eye gesture communication system that runs on a smartphone, and is designed to be low-cost, robust, portable, and easy-to-learn, with a higher communication bandwidth than an e-tran board. GazeSpeak can interpret eye gestures in real time, decode these gestures into predicted utterances, and facilitate communication, with different user interfaces for speakers and interpreters. Our evaluations demonstrate that GazeSpeak is robust, has good user satisfaction, and provides a speed improvement with respect to an e-tran board; we also identify avenues for further improvement to low-cost, low-effort gaze-based communication technologies.
