A framework for gaze selection techniques (Tonder et al., 2008)

Martin van Tonder, Charmain Cilliers and Jean Greyling at the Nelson Mandela Metropolitan University, South Africa presented a platform independent framework in the proceedings of the 2008 annual research conference of the South African Institute of Computer Scientists. The framework is platform independent (relying on Java) and supports multiple interaction methods such as Kumars EyePoint, popups, as well as data logging and visualization.

Experimental gaze interaction techniques are typically prototyped from scratch using proprietary libraries provided by the manufacturers of eye tracking equipment. These libraries provide gaze data interfaces, but not any of the additional infrastructure that is common to the implementation of such techniques. This results in an unnecessary duplication of effort. In this paper, a framework for implementing gaze selection techniques is presented. It consists of two components: a gaze library to interface with the tracker and a set of classes which can be extended to implement different gaze selection techniques. The framework is tracker and operating system independent, ensuring compatibility with a wide range of systems. Support for user testing is also built into the system, enabling researchers to automate the presentation of est targets to users and record relevant test data. These features greatly simplify the process of implementing and evaluating new interaction techniques. The practicality and flexibility of the framework are demonstrated by the successful implementation of a number of gaze selection
