Co-modal browser-an interface for wearable computers

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-and-eyes-free use. Usability test results are presented that should be of use to wearable computer researchers concerned with hands-and-eyes-free use. The co-modal concept is demonstrated as being viable on an HDML browser.
