Smart Homes are generally considered the final solution for living problem, especially for the health care of the elderly and disabled, power saving, etc. Human activity recognition in smart homes is the key to achieving home automation, which enables the smart services to automatically run according to the human mind. Recent research has made a lot of progress in this field; however, most of them can only recognize default activities, which is probably not needed by smart homes services. In addition, low scalability makes such research infeasible to be used outside the laboratory. In this study, we unwrap this issue and propose a novel framework to not only recognize human activity but also predict it. The framework contains three stages: recognition after the activity, recognition in progress, and activity prediction in advance. Furthermore, using passive RFID tags, the hardware cost of our framework is sufficiently low to popularize the framework. In addition, the experimental result demonstrates that our framework can realize good performance in both activity recognition and prediction with high scalability.
智能家居通常被认为是解决生活问题的最终方案,特别是在老年人和残疾人的医疗保健、节能等方面。智能家居中的人体活动识别是实现家庭自动化的关键,这使得智能家居服务能够根据人的思维自动运行。最近的研究在这一领域取得了很大的进展;然而,大多数研究只能识别默认活动,这可能不是智能家居服务所需要的。此外,低可扩展性使得此类研究无法在实验室之外使用。在本研究中,我们解决了这个问题,并提出了一种新颖的框架,不仅可以识别人体活动,还可以预测人体活动。该框架包含三个阶段:活动后的识别、进行中的识别和提前的活动预测。此外,使用被动 RFID 标签,我们框架的硬件成本足够低,可以推广该框架。此外,实验结果表明,我们的框架可以在具有高可扩展性的情况下实现良好的活动识别和预测性能。
