In a piano lesson, a student often imitates how her teacher is playing in terms of speed, dynamics, and fingering. We seek to convey the touch sensations in piano lessons between a teacher and a student by sensing the teacher's keystrokes and then tapping the student's fingers appropriately. Here, we propose an implementation to sense finger taps on hard surfaces by using an instrumented glove....

Many techniques have been developed for 3D object deformation. These techniques have been widely used in most CAD/CAM systems. Intuitive while efficient methods for interactive 3D object deformation in a VR environment, however, are rare. One of our current research projects is to develop such a technique based on the use of a sensor glove. The idea is to create a hand surface interpolating thr...

Quantitative assessment of digit range of motion (ROM) is often needed for monitoring effectiveness of rehabilitative treatments and assessing patients' functional impairment. The objective of this research was to investigate the feasibility of using the Humanware Humanglove, a 20-position sensors glove, to measure fingers' ROM, with particular regard to measurement repeatability. With this aim...

Navigational systems guide users providing visual and acoustic indications, burdening user’s attention. On the one hand, following visual guidance is challenging because of the constant need to switch the gaze between the display and the surroundings. On the other hand, auditory indications can be obtrusive and inefficient. Tactile displays, i.e., systems that send stimuli via the tactile chann...

We present a novel dataglove mapping technique based on parameterisable models that handle both the cross coupled sensors of the fingers and thumb, and the under-specified abduction sensors for the fingers. Our focus is on realistically reproducing the posture of the hand as a whole, rather than on accurate fingertip positions. The method proposed in this paper is a vision-free, object free, da...

PURPOSE To develop a system for refined motor control of artificial hands based on multiple electromyographic (EMG) recordings, allowing multiple patterns of hand movements. METHODS Five subjects with traumatic below-elbow amputations and 1 subject with a congenital below- elbow failure of formation performed 10 imaginary movements with their phantom hand while surface electrodes recorded the...

OBJECTIVES Design, construct, and characterize an apparatus to evaluate dermal protective clothing for resistance to polymerizing materials. Specifically, we evaluated the permeation of the most common glove material used in automotive collision repair (0.10-0.13 mm or 4-5 mil latex) with representative isocyanate-containing clear coats. Our ultimate goal is to make informed recommendations on ...

BACKGROUND The use of gloves for every patient contact (ie, universal gloving) has been suggested as an infection prevention adjunct and alternative to contact precautions. However, gloves may carry organisms unless they are changed properly. In addition, hand hygiene is required before donning and after removing gloves, and there are scarce data regarding glove changing and hand hygiene in a u...
