For patients with severe motor disabilities, a robust means of communication is a crucial factor for their well-being [1]. We report here that pupil size measured by a bedside camera can be used to communicate with patients with locked-in syndrome. With the same protocol we demonstrate command-following for a patient in a minimally conscious state, suggesting its potential as a diagnostic tool for patients whose state of consciousness is in question. Importantly, neither training nor individual adjustment of our system's decoding parameters were required for successful decoding of patients' responses.
对于严重运动障碍的患者来说，强大的沟通方式是其幸福感的关键因素[1]。我们在此报告，通过床边摄像头测量瞳孔大小可以用于与闭锁综合征患者进行交流。使用相同的方案，我们还展示了对处于最小意识状态的患者的指令跟随，这表明其作为对意识状态存在疑问的患者的诊断工具具有潜力。重要的是，我们的系统解码参数既不需要进行训练，也不需要进行个别调整，就可以成功解码患者的反应。
