在本文中，我们描述了一个机器人轮椅系统作为指导机器人。该系统检测用户的头部姿势和注视方向，并使用距离传感器和地图识别其位置和周围环境。由于该系统可以从测量中检测用户正在看哪里，因此它可以通过注视的持续时间来估计用户在轮椅上的注意力。实验结果表明，利用用户注意力估计进行速度控制辅助的有效性。
In this paper, we describe a robotic wheelchair system as a guide robot. This system detects the head pose and gaze direction of the user, and recognizes its position and the surrounding environment using a range sensor and a map. Since the system can detect where the user is looking from the measurements, it can estimate the attention of the user on the wheelchair by the duration of gaze. Experimental results indicate the validity of the speed control assistance using the estimation of user's attention.
