Analyzing Eye-gaze Interaction Modalities in Menu Navigation

While eye-gaze interaction for disabled people proved to work fine, its usability in general cases is still far from being integrated. In order to design a wearable interface for military products, several modalities using the eye were tested. We proposed a new modality named Relocated DwellTime which aimed at giving more control than existing modalities. We then conceived an experimental military representative observation task where 4 interaction modalities using the eye were tested (2 eye-only and 2 multimodal methods using an external physical button). The experiment evaluated the effect of two types of menus, circular and linear, on eye-gaze interactions performances. Significant results were observed regarding interaction modalities. The modality adding a physical button proved significantly more efficient than eye-only methods in this context and instant opening of menus was rather accepted despite the hypothesis of the literature. No impact of the menu type was observed.
