While gesture controls will be important as future computing input modalities, they are limited by reduced performance and increase ergonomic risk. Performance of pointing in free-hand gestural controls is affected by control-display (CD) parameters

Installation of grab bars and handholds are recommended to reduce risk of injuries commonly resulting from unsuccessful transfers in the bath/shower/tub. However, few empirical investigations or studies of handhold and grab bar placement are availabl

BACKGROUND: Extended use of conventional computer input devices is associated with negative musculoskeletal outcomes. While many alternative designs have been proposed, it is unclear whether these devices reduce biomechanical loading and musculoskele

Recent technologies now allow touchless gestural controls to be integrated as computing input devices. Unlike traditional input devices, the effect of design parameters (such as control-display transfer functions for physical to onscreen movements) f

The recent development of affordable technologies now allow touchless gestural controls to be integrated in common computing environments, however, ergonomic issues (user fatigue, in particular) have not been solved. This experiment investigates shou

The use of forearm and palm supports has been associated with lower neck and shoulder muscle activity as well as reduced musculoskeletal discomfort during keyboard use, however, few studies have investigated their effect during computer mouse use. Ei

While the hardware challenges facing integration of hand-gestural controls into mainstream computer interfaces appear to be shrinking, design challenges related to the physical and mental burden required of gesture interfaces remain. This study aims

BACKGROUND: Falls are the leading cause of nonfatal unintentional injuries among hospitalized children with playground equipment accounting for more than 50%. National standards for playground rung and rail design exist, but there a lack of in vivo m

The purpose of this experiment was to quantify the natural angle between the hand and a handle, and to investigate three design factors: handle rotation, handle tilt and between-handle width on the natural angle as well as resultant wrist radial/ulna
