This study proposes a home care system (HCS) based on a brain-computer interface (BCI) with a smartphone. The HCS provides daily help to motor-disabled people when a caregiver is not present. The aim of the study is two-fold: (1) to develop a BCI-based home care system to help end-users control their household appliances, and (2) to assess whether the architecture of the HCS is easy for motor-disabled people to use. A motion-strip is used to evoke event-related potentials (ERPs) in the brain of the user, and the system immediately processes these potentials to decode the user’s intentions. The system, then, translates these intentions into application commands and sends them via Bluetooth to the user’s smartphone to make an emergency call or to execute the corresponding app to emit an infrared (IR) signal to control a household appliance. Fifteen healthy and seven motor-disabled subjects (including the one with ALS) participated in the experiment. The average online accuracy was 81.8% and 78.1%, respectively. Using component N2P3 to discriminate targets from nontargets can increase the efficiency of the system. Results showed that the system allows end-users to use smartphone apps as long as they are using their brain waves. More important, only one electrode O1 is required to measure EEG signals, giving the system good practical usability. The HCS can, thus, improve the autonomy and self-reliance of its end-users.

致力于通过智能手机无障碍使用基于脑机接口的家庭护理系统。

这项研究提出了一种基于带有智能手机的脑机接口（BCI）的家庭护理系统（HCS）。如果没有护理人员，HCS会为行动不便的人提供日常帮助。该研究的目的有两个方面：（1）开发基于BCI的家庭护理系统，以帮助最终用户控制其家用电器；（2）评估HCS的体系结构是否易于残障人士使用。人们使用。运动条用于唤起用户大脑中与事件相关的电位（ERP），并且系统立即处理这些电位以解码用户的意图。然后，系统将这些意图转换为应用程序命令，并通过蓝牙将其发送到用户的智能手机以进行紧急呼叫或执行相应的应用程序以发出红外（IR）信号来控制家用电器。15名健康者和7名运动障碍者（包括ALS患者）参加了该实验。平均在线准确性分别为81.8％和78.1％。使用组件N2P3区分目标与非目标可以提高系统的效率。结果表明，该系统允许最终用户只要使用脑电波就可以使用智能手机应用程序。更重要的是，只需要一个电极O1即可测量EEG信号，从而使系统具有良好的实用性。因此，HCS可以改善其最终用户的自主权和自力更生。结果表明，该系统允许最终用户只要使用脑电波就可以使用智能手机应用程序。更重要的是，仅需一个电极O1即可测量EEG信号，从而使系统具有良好的实用性。因此，HCS可以改善其最终用户的自治性和自力更生。结果表明，该系统允许最终用户只要使用脑波就可以使用智能手机应用程序。更重要的是，只需要一个电极O1即可测量EEG信号，从而使系统具有良好的实用性。因此，HCS可以改善其最终用户的自治性和自力更生。
