The text 2.0 framework: writing web-based gaze-controlled realtime applications quickly and easily

We created a simple-to-use framework to construct gaze-responsive applications using web technology focussing on text. A plugin enables any compatible browser to interpret a new set of gaze handlers that behave similar to existing HTML and JavaScript mouse and keyboard event facilities. Keywords like onFixation, onGazeOver, and onRead can be attached to parts of the DOM tree and are triggered on the corresponding viewing behavior. The plugin is part of a distributed architecture featuring a remote gaze provider and a number of assisting services and tools. Using this framework we implemented a number of applications providing help on comprehension difficulties.
