Yoga has been a great form of physical activity and one the promising applications in personal health care. Several studies prove that yoga is used as treatments for cancer, musculoskeletal disorder, depression, Parkinson’s disease, respiratory heart diseases. In yoga, body should be mechanically aligned with some effort on muscles, ligaments, joints optimal posture. Postural-based increases fl...

INTRODUCTION Options currently available to individuals with upper limb loss range from prosthetic hands that can perform many movements, but require more cognitive effort to control, to simpler terminal devices with limited functional abilities. We attempted to address this issue by designing a myoelectric control system to modulate prosthetic hand posture and digit force distribution. METHO...

There are infinitely many different combinations of arm postures which will place the hand at the same point in space. Given this abundance, how is one configuration chosen over another? Two main hypotheses have been proposed to solve this problem. Postural models suggest that the posture adopted is purely determined by the desired hand position (known as Donders' law). Transport models suggest...

This paper focuses on a design case study of a natural hand gesture system for users with intact motion control of the metacarpophalangeal joint and thumb basal joint of the hand after brachial plexus injuries. The lexicon of hand gestures had eight entries and was demonstrated to be natural and ergonomic with the limited hand motions. A cooperative multi-cue system was proposed for the key han...

Sleep posture is a key component in sleep quality assessment and pressure ulcer prevention. Currently, body pressure analysis has been a popular method for sleep posture recognition. In this paper, a matching-based approach, Body-Earth Mover's Distance (BEMD), for sleep posture recognition is proposed. BEMD treats pressure images as weighted 2D shapes, and combines EMD and Euclidean distance fo...

Communication between human and hearing impair persons is very difficult in daily life. Sign language interpretation system can translate signs into text or voice for solving this problem. In practically, however, it is not convenient because it cannot be carried by the signer. It is better if the hearing impair persons can bring the sign language interpretation with themselves all the times su...

The postures of wheelchair users can reveal their sitting habit, mood, and even predict health risks such as pressure ulcers or lower back pain. Mining the hidden information of the postures can reveal their wellness and general health conditions. In this paper, a cushion-based posture recognition system is used to process pressure sensor signals for the detection of user's posture in the wheel...

The paper addresses the problem of visual recognition of several hand postures corresponding to a few operations commonly performed in virtual environments, such as: object selection, translation, rotation and resizing. Processing is performed in a top-view scenario with a top-mounted camera that monitors the user’s hands on the working desktop. By careful choosing and controlling of the scene ...
