We investigate how to seamlessly bridge the gap between users and distant displays for basic interaction tasks, such as object selection and manipulation. For this, we take advantage of very fast and implicit, yet imprecise gaze- and head-directed input in combination with ubiquitous smartphones for additional manual touch control. We have carefully elaborated two novel and consistent sets of gaze-supported interaction techniques based on touch-enhanced gaze pointers and local magnification lenses. These conflict-free sets allow for fluently selecting and positioning distant targets. Both sets were evaluated in a user study with 16 participants. Overall, users were fastest with a touch-enhanced gaze pointer for selecting and positioning an object after some training. While the positive user feedback for both sets suggests that our proposed gaze- and head-directed interaction techniques are suitable for a convenient and fluent selection and manipulation of distant targets, further improvements are necessary for more precise cursor control. |
