An Integrated Bimanual Computer Input Station: the Command Chair
نویسندگان
چکیده
A new computer input device, the Command Chair, has been developed to provide bimanual (or, two-handed) input while also addressing several additional ergonomic issues. In particular, the Command Chair integrates an office chair, keyboard input, bimanual pointer input, and forearm support into a single system. This allows a designer to consider the input system as a whole, rather than as a collection of individual devices. In turn, this allows for better control of body activities and postures, with the goal of providing user comfort over a full workday. This system uses the location of the keyboard to position the mouse, removing the need to switch between devices. Preliminary testing indicates that the Command Chair reduces wrist fatigue relative to a traditional input station, but also provides slower pointing speed partially attributable to higher system inertia.

Toolglasses, Marking Menus, and Hotkeys: A Comparison of One and Two-Handed Command Selection Techniques
Research has shown that bimanual (two-handed) interfaces often provide more intuitive, efficient, and comfortable interaction than one-handed interfaces. This paper introduces a new input technique, bimanual marking menus, and compares its performance with five other techniques: static toolbars, hotkeys, grouped hotkeys, marking menus, and toolglasses. The study builds on previous work by setti...

متن کاملThe Interactive Bracelet: An input device for bimanual interaction
The size of a mobile device limits its input capabilities. To address this problem, we propose the Interactive Bracelet, an input device worn on the wrist that brings bimanual gestures to the mobile or ubiquitous computer. We describe example scenarios that illustrate how we imagine the device could be used, and we discuss how the device can be implemented and what sensors and actuators should ...
