The Office Keyboard (on store shelves in major markets since October, 2001) seeks to enhance efficiency through unique application of bimanual interaction principles. The left hand performs navigation tasks (including view scrolling, application switching, and internet forward & back) as well as editing commands (Cut, Copy, and Paste) that are typically(More)
Conventional, straight keyboards remain the most popular design among keyboards sold and used with personal computers despite the biomechanical benefits offered by alternative keyboard designs. Some typists indicate that the daunting medical device-like appearance of these alternative 'ergonomic' keyboards is the reason for not purchasing an alternative(More)
Two-button computer mouse users may exhibit sustained, static finger lifting behaviours to prevent inadvertent activations by avoiding finger pressure on the buttons, which leads to prolonged, static finger extensor muscle loading. One hundred graduate students were observed during normal computer work in a university computer facility to qualify and(More)
OBJECTIVE The purpose of this study was to design and test alternative computer mouse designs that attempted to reduce extensor muscle loading of the index and middle fingers by altering the orientation of the button switch direction and the force of the switch. BACKGROUND Computer users of two-button mouse designs exhibit sustained lifted finger(More)
Among many important attributes, designers often seek to create products that are comfortable both in the sense of avoiding discomfort and providing a positive sense of comfort. Another way of looking at the design of hand-held products is to consider what attributes make a product enjoyable to touch, rather than just comfortable or uncomfortable. A series(More)
OBJECTIVE Research has shown that fixed-split, ergonomic keyboards lessen the pain and functional status in symptomatic individuals as well as reduce the likelihood of developing musculoskeletal disorders in asymptomatic typists over extended use. The goal of this study was to evaluate design features to determine whether the current fixed-split ergonomic(More)
Ergonomic principles of human performance and human-machine interaction are applied to the design of a new, commercially available computer keyboard. Even though it is a primary means to connect people with computer applications, the keyboard has remained relatively static in design. This paper describes concepts and features implemented on a new computer(More)
OBJECTIVE Tablets and other mobile devices can be tilted during use. This study examined the effect of tablet tilt angles on reading performance, target-tapping performance, wrist and forearm posture, user comfort and users' tilt angle preferences. METHOD Ten participants used tablets alternating among four different tilt angles: 0°, 30°, 45°, 60° and a(More)
BACKGROUND Increasingly, evidence shows that prolonged sedentary behavior factors into the health equation on its own, unrelated to weight and periods of intense exercise. In schools, students are required to sit for long periods of time. OBJECTIVE To investigate whether reminders (via a wearable device) to change posture, can change students' behavior(More)
