© Published under licence by IOP Publishing Ltd. Some disabilities caused by sensory malfunction, accident, or congenital disorder could cause people difficulty in grasping the computer mouse. A well-known substitute uses an inertial sensor to monitor the body's orientation. This paper evaluates the efficiency and effectiveness of different methods of holding the sensor. There are two modes of holding the sensor, the grasping mode and the attached mode; we also evaluate a mouse as a baseline. The attached mode works by placing the sensor on the back of user's hand. The quantitative and qualitative evaluation procedure is based on ISO/TS 9241 part 411: Ergonomics of human-system interaction standard. The test consists of four levels of difficulty and indicates that the throughput and task completion times were not statistically different between grasping and attached mode. We also found that grasping mode and attached mode did not show significantly statistical differences in comfort and fatigue based on the questionnaires. The results also suggest that the orientation of the hand used in grasping and attached modes is suitable only for lower-impact computer use.

MUSCULOSKELETAL SIMULATION OF THE RELATIONSHIP BETWEEN FOOT POSITION AND STRESS OF THE L4-L5 JOINT IN SUPPORTING STANDING-UP MOTION TO PREVENT LOW BACK PAIN AMONG CAREGIVERS 査読有り国際誌

© 2019 World Scientific Publishing Company. Most caregivers have low back pain which results from frequent care activities such as assistance motion that supports transfer and standing-up. Various parameters are associated with the caregiver's lumbar load. In this study, we focus on the foot position of the caregiver as one of the subjective adjustable parameters. This study aimed to analyze the relationship between foot position and stresses of the L4-L5 joint as lumbar load during supporting standing-up via musculoskeletal simulation. The musculoskeletal model was tasked with simulating supported standing-up motions based on a specific pelvic position and angular variation of each joint. The anterior foot (left foot) was fixed, and the posterior foot (right foot) was moved to three backward positions and three rightward positions, thus obtaining nine posterior foot positions. Compressive, anteroposterior shear, and lateral shear stresses of the L4-L5 joint were compared for nine foot positions. The results showed that as the anteroposterior distance and lateral widths between both feet increased, the average value of compressive/shear stress of the L4-L5 joint during motions decreased. From our findings, we hypothesized that the foot position may reduce the lumbar load and prevent low back pain.

Cane with millimeter wave radar for base of support measurement 査読有り国際誌

Fernandez I.G., Wada C.

© 2019 IEEE. Base of Support (BoS) is a significant parameter for balance analysis. It is particularly important for people using assistive devices such as canes or walkers, because assistive devices improve the stability of the user by increasing the Base of Support. The objective of this research is to develop a wearable device that is able to analyze balance by measuring the position of the Center of Gravity (CoG) inside the Base of Support while using a cane. In this paper, we present our initial work to measure the Base of Support. We developed an instrumented cane with a millimeter wave radar in order to measure the Base of Support in real time. The point cloud data from the radar were grouped into clusters to identify the points belonging to each foot. A density-based spatial clustering of applications with noise (DBSCAN) algorithm was used for this purpose. Finally, the right and left foot were differentiated based on the position of the centroid of each cluster. Knowing the position of both feet with respect to the cane, we were able to measure the BoS with an error of 92.04 cm2(7.38 %).
