Abstract

Recent keyboard-based alternatives to WIMP interfaces do not have good support for commands that require multiple parameters. We remedy this by extending a previous design and mimicking dialog boxes to provide good visual feedback while still keeping the advantages of keyboard input. A laboratory study showed the new technique to be competitive with dialog boxes on speed and error rate, but strongly preferred over dialog boxes by experienced command line users. This is a marked improvement over the previous design, which was also preferred by the target user group but did not compete with dialog boxes in terms of performance.
