TiltType is a novel text entry technique for mobile devices. To enter a character, the user tilts
the device and presses one or more buttons. The character chosen depends on the button
pressed, the direction of tilt, and the angle of tilt. TiltType consumes minimal power and
requires little board space, making it appropriate for wristwatch-sized devices. But because
controlled tilting of one's forearm is fatiguing, a wristwatch using this technique must be

TiltType is a novel text entry technique for mobile devices. To enter a character, the user tilts the device and presses one or more buttons. The character chosen depends on the button pressed, the direction of tilt, and the angle of tilt. TiltType consumes minimal power and requires little board space, making it appropriate for wristwatch-sized devices. But because controlled tilting of one's forearm is fatiguing, a wristwatch using this technique must be easily removable from its wriststrap. Applications include two-way paging, text entry for watch computers, web browsing, numeric entry for calculator watches, and existing applications for PDAs.
