In this paper, a controlling system is implemented for a wearable walking supporting device so called as Mechanically Automated Renovative Under Transforming Intelligence (MARUTI). The control circuit is implemented without considering the biological signals of the human body for the knee part, which is based on the knee joint moment from the human body model. The control and a driving circuits...

We present an eyeglass-type wearable device that has light emitting diode (LED) indicators on the frame. The device produces lighting patterns of 14 RGB LEDs near user’s eyes as guiding information. Since installed LEDs are light and saving power, it is feasible to develop it for daily use. On the other hand, it cannot provide rich information such as text or images. In this study, we aim to re...

The present study describes the development of a wearable device designed to assist those who work in an unstructured posture. In manufacturing sector, industrial accidents have been steadily on rise due poor environments and excessive workloads imposed workers. Against this backdrop, aimed analyze various types work, especially performed postures by heavy industry workers, are frequently expos...

Compensating the weight of human limbs is important in reducing muscle fatigue experienced by manual laborers. In this study, a compact and lightweight soft wearable weight support device was developed and evaluated. The device supports gravitational force on the shoulder at any arm posture, although there are some limitations in its assistive performance. The device actuator consists of a cam-...

BACKGROUND Wearable sensors gather data that machine-learning models can convert into an identification of physical activities, a clinically relevant outcome measure. However, when individuals with disabilities upgrade to a new walking assistive device, their gait patterns can change, which could affect the accuracy of activity recognition. OBJECTIVE The objective of this study was to assess ...
