On-desktop projection have been proposed for learning support systems for math development [Beşevli et al. 2019] and typing on a physical keyboard [Sono and Hasegawa 2019]. On-body projection systems were developed for education [Hoang et al. 2017][Ferdous et al. 2019]. Although projection-based human-machine interfaces have attracted attention, there have been very few works on integration with sensor-based activity recognition. Therefore, in this paper we propose an SAR assistance system with accelerometer and projection mapping. We considered cleaning activities [Yaegashi et al. 2022] for recognition to achieve wellbeing during and after the pandemic. The contribution of the proposed idea is to integrate SAR and real-time activity recognition technologies. The sensor-based activity recognition is advantageous in terms of privacy compared with well-known gesture recognition systems using a camera. The fixed floor-projection also contributes for disuse of a camera by avoiding dynamic calibration. A small and light-weight sensor device mounted on a cleaning tool does not affect the action. Low-latency feedback is achieved by an edge computing based architecture.
