Bimanual Interaction on the Microsoft Office Keyboard.
Hugh E. McLoone, Ken Hinckley, Edward B. Cutrell · 2003
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 part of a compound mouse-keyboard action. The Office Keyboard’s Cut, Copy, Paste, and Application toggle dedicated left-side keys are evaluated. Results in three different experimental task contexts show that the Office Keyboard is significantly faster than, or statistically equivalent to, the mouse or keyboard shortcuts (Ctrl-X, Ctrl-C, Ctrl-V and Alt+Tab) for all outcome measures that we collected. Most participants preferred the dedicated left-side keys to the other methods tested.
