Further testing the performance of ExposeHK in CommandMaps-like interfaces and a semi-realistic task

Type: conference-paper
Abstract: ExposeHK is an interaction technique that displays available keyboard shortcuts over a Graphical User Interface (GUI), making it possible to activate keyboard shortcuts without having to memorize them beforehand. We conducted two studies to further assess the potential of ExposeHK as an efficient command selection mechanism in a GUI displaying a large number of commands (CommandMaps), and in a text formatting task. Our results suggest that ExposeHK is 26% faster than pointer for selecting commands, that users spontaneously use more keyboard shortcuts when ExposeHK is available, and also hint that users might incidentally memorize some of them.
