This paper reports an electroencephalogram-based brain-actuated telepresence system to provide a user with presence in remote environments through a mobile robot, with access to the Internet. This system relies on a P300-based brain-computer interface (BCI) and a mobile robot with autonomous navigation and camera orientation capabilities. The shared-control strategy is built by the BCI decoding of task-related orders (selection of visible target destinations or exploration areas), which can be autonomously executed by the robot. The system was evaluated using five healthy participants in two consecutive steps: 1) screening and training of participants and 2) preestablished navigation and visual exploration telepresence tasks. On the basis of the results, the following evaluation studies are reported: 1) technical evaluation of the device and its main functionalities and 2) the users' behavior study. The overall result was that all participants were able to complete the designed tasks, reporting no failures, which shows the robustness of the system and its feasibility to solve tasks in real settings where joint navigation and visual exploration were needed. Furthermore, the participants showed great adaptation to the telepresence system.
本文报道了一种基于脑电图的脑控远程临场感系统,该系统通过一个可接入互联网的移动机器人,让用户在远程环境中获得临场感。该系统依赖于基于P300的脑机接口(BCI)以及具有自主导航和摄像头定向能力的移动机器人。共享控制策略通过对与任务相关的指令(选择可见目标目的地或探索区域)进行BCI解码构建而成,这些指令可由机器人自主执行。该系统通过连续两个步骤对五名健康参与者进行了评估:1)参与者的筛选和训练;2)预先设定的导航和视觉探索远程临场感任务。基于这些结果,报告了以下评估研究:1)设备及其主要功能的技术评估;2)用户行为研究。总体结果是,所有参与者都能够完成设计的任务,未报告失败情况,这表明了系统的稳健性及其在需要联合导航和视觉探索的实际场景中解决任务的可行性。此外,参与者对远程临场感系统表现出了很好的适应性。
