本文介绍了使用贝叶斯网络提供上下文感知的共享控制的机器人移动援助脆弱的盲人。机器人助行器PAM-AID是一种“智能步行者”，旨在帮助体弱和年老的盲人在室内安全行走。贝叶斯网络将用户输入与来自传感器的高级信息相结合，以提供对用户当前导航目标的上下文感知估计。这种上下文感知的操作选择机制有助于使用非常简单、低带宽的用户界面，这对老年用户组至关重要。通过一系列实地试验对PAM-AID系统进行了评价，有30多个潜在用户参加。
This paper describes the use of a Bayesian network to provide context-aware shared control of a robot mobility aid for the frail blind. The robot mobility aid, PAM-AID, is a “smart walker” that aims to assist the frail and elderly blind to walk safely indoors. The Bayesian network combines user input with high-level information derived from the sensors to provide a context-aware estimate of the user’s current navigation goals. This context-aware action selection mechanism facilitates the use of a very simple, low bandwidth user interface, which is critical for the elderly user group. The PAM-AID systems have been evaluated through a series of field trails involving over 30 potential users.
