KeyTch: Combining the Keyboard with a Touchscreen for Rapid Command Selection on Toolbars

要旨

In this paper, we address the challenge of reducing mouse pointer transitions from the working object (e.g. text document) to simple or multi-level toolbars on desktop computers. To this end, we introduce KeyTch (pronounced ‘Keetch’), a novel approach for command selection on toolbars based on the combined use of the keyboard with a touchscreen. The toolbar is displayed on the touchscreen, which is positioned below the keyboard. Users can select commands by performing gestures combining a key press with the pinky finger, and a screen touch with the thumb of the same hand. After analyzing the design properties of KeyTch, a preliminary experiment validates that users can perform such gestures and reach the entire touchscreen surface with the thumb. Then a first user study unveils that direct touch outperforms indirect pointing to reach items on a simple toolbar displayed on the touchscreen. In a second study, we validate that KeyTch interaction techniques outperform the mouse for selecting items on a multi-level toolbar displayed on the touchscreen, allowing to select up to 720 commands with an accuracy above 95%, or 480 commands with an accuracy above 97%. Finally, two follow-up studies validate the benefits of KeyTch when used in a more integrated context.
