Abstract

Disclosed here are a set of methods for entering information into a mobile device which is constrained in terms of its input devices. In particular the methods are applicable to a wrist watch device. Such mobile devices are too small to include a keyboard or even a telephone type keypad. We present a scheme that uses a roller wheel combined with a touch sensitive screen to enable users to enter alphabets, numbers and special characters easily. We also describe how users can backspace and correct mistakes during the text input process.
