ABSTRACT
Pie menus offer several features which are advantageous especially for gaze control. Although the optimal number of slices per pie and of depth layers has already been established for manual control, these values may differ in gaze control due to differences in spatial accuracy and congitive processing. Therefore, we investigated the layout limits for hierarchical pie menu in gaze control. Our user study indicates that providing six slices in multiple depth layers guarantees fast and accurate selections. Moreover, we compared two different methods of selecting a slice. Novices performed well with both, but selecting via selection borders produced better performance for experts than the standard dwell time selection.

Gazing with pEYEs: towards a universal input for various applications
ETRA '08: Proceedings of the 2008 symposium on Eye tracking research & applicationsVarious interfaces for gaze control (which are recommended due to certain requirements of controlling a machine by gaze) have already been developed. One problem, especially for novice users, is that respective interfaces all look different and require ...
An alternative selection method for pie menus: selection by borders
APGV '09: Proceedings of the 6th Symposium on Applied Perception in Graphics and VisualizationPie menus offer several features, which are advantageous especially for gaze control. However, one disadvantage is still that pies are usually to be selected by dwell times. An alternative is selection by borders. We compared selection by borders and ...
Gazing with pEYE: new concepts in eye typing
APGV '07: Proceedings of the 4th symposium on Applied perception in graphics and visualizationEye typing applications like a virtual keyboard are often straining to use. We developed various interfaces based on different theoretical ideas. In Iwrite, letters are selected by gazing towards the outer frame of the monitor. This should minimize the ...
