Abstract
This paper describes user tests on a co-modal browser, a general interface for wearable devices that can communicate through a browser. The co-modal browser is a Handheld Device Markup Language (HDML) browser with fully integrated visual display, synthetic speech, voice command, short sounds and buttons. The browser was tested for hands-free, eyes-free, and hands & eyes-free use. Usability test results are presented here of use to wearable computer researchers concerned with hands & eyes-free use. The co- modal concept is demonstrated as viable on an HDML browser.
