As discussed earlier in my blog the differences between gaze vs mouse based interaction calls for interfaces that are especially designed for the purpose. A group of German researchers present a novel approach based on a radial menu layout. The work has been carried out by Yvonne Kammerer and Katharina Scheiter both at the Knowledge Media Research Center, University of Tuebingen in conjunction with Wolfgang Beinhauer at the Fraunhofer Institute for Industrial Engineering, Stuttgart.
My own prototype contains U.I elements that are based on the same on the style of interaction. However, this work goes further towards a multi-level menu system while my component is aiming more for a quick one-level saccade selection. The advantages of the radial layout in a gaze based menu component is discussed in this paper. Interesting concept, looking forward to the presentation at the SWAET2008 conference.

Abstract
"In this paper a study is reported, which investigates the effectiveness of two approaches to improving gaze-based interaction for realistic and complex menu selection tasks. The first approach focuses on identifying menu designs for hierarchical menus that are particularly suitable for gaze-based interaction, whereas the second approach is based on the idea of combining gaze-based interaction with speech as a second input modality. In an experiment with 40 participants the impact of menu design, input device, and navigation complexity on accuracy and completion time in a menu selection task as well as on user satisfaction were investigated. The results concerning both objective task performance and subjective ratings confirmed our expectations in that a semi-circle menu was better suited for gaze-based menu selection than either a linear or a full-circle menu. Contrary to our expectations, an input device solely based on eye gazes turned out to be superior to the combined gaze- and speech-based device. Moreover, the drawbacks of a less suitable menu design (i.e., of a linear menu or a full-circle menu) as well as of the multimodal input device particularly obstructed performance in the case of more complex navigational tasks."
