ABSTRACT
In this paper we describe a new method for doing text input with touch sensitive wheels. The method is called Transparent User guided Prediction (TUP). With TUP all characters are assigned to fixed positions on the wheel. A language prediction algorithm is used to make it easy to select the most likely characters. The use of the prediction algorithm is transparent for the users, which makes the use of TUP very intuitive. A prototype of TUP is evaluated against the date stamp method for doing wheel text input. Text entry speed for TUP is about 6-7 words per minute for novice users. This is approximately 30% faster than the date stamp method.

Input finger detection for nonvisual touch screen text entry in Perkinput
GI '12: Proceedings of Graphics Interface 2012We present Input Finger Detection (IFD), a novel technique for nonvisual touch screen input, and its application, the Perkinput text entry method. With IFD, signals are input into a device with multi-point touches, where each finger represents one bit, ...
Stylus based text input using expanding CIRRIN
AVI '06: Proceedings of the working conference on Advanced visual interfacesCIRRIN [3] is a stylus based text input technique for mobile devices with a touch sensitive display. In this paper we explore the benefit of expanding the letters of CIRRIN to reduce the overall difficulty of selecting a letter. We adapted the existing ...
