Freepad

Freepad is a novel handwriting-based text input method that supports “attention-free” or “heads-up” interaction with pen and touch interfaces. It is an Input Method Editor (IME) that allows the user to overwrite standard characters in an alphabet one over another and is particularly suitable for small surfaces. It does not expect that the relative position between strokes and/or characters be maintained in order to support attention-free or heads-up text input.

The prototype word recognition system that currently recognizes lowercase English and Tamil words. FreePad currently runs on a notebook computer, and captures overwriting input as a sequence of finger strokes from the notebook’s touchpad.

Gesture-based Command and Control (GECCO)

 

Gesture-based Command and Control allows users to access applications, URLs, system commands and application demands simply by tracing a gesture with either a finger or stylus. This gesture can be personal, either a familiar character or an arbitrary shape. Highly accurate gesture recognition is achieved over a period of time because the system learns and refines its recognition with each use. Gesture-based navigation uses special gestures to more efficiently navigate files, folders, playlists and bookmarks.
