Intention-Aware Gaze-Based Assistance on Maps (IGAMaps)Adaptive human computer interfaces can significantly facilitate the interaction with digital maps in application scenarios such as navigation, information search, and for users with physical limitations. A map system that is able to recognize its user’s information requirements fast and accurately could adapt the map content, thus increasing effectiveness and efficiency of interaction. Since maps are primarily perceived and explored with the visual sense, it is plausible to assume that a user’s gaze on a map can be used to recognize intentions and activities, which can then trigger map adaptation.The main goal of this research project consists in the investigation of methods for the recognition of activities and intentions from visual attention during the interaction with maps. The project tries to answer the following questions:
- Can we infer a map user’s activity and intention from the visual attention he or she is spending on the map (e.g., route planning, searching for a restaurant)?
- How should a map adaptation be designed to be helpful?
- What is the general user acceptance of gaze-based intention recognition on maps?
Diploma Thesis "A Concept to Leverage the Visual Periphery for Parallel Information"Over the last years, display screens have drastically improved not only with respect to resolution but also in terms of dimension. Many applications utilize this space for presenting more information as well as to support multiple task by still applying conventional UI paradigms. Considering peoples visual focus of attention to be limited by human factors, intelligent UIs have to be developed to take better advantage of the gained space. This work investigates, using the visual periphery for displaying information while focusing on a primary task. Based on the understanding of the human visual system, vital aspects for perceiving information within the field of view have been tested in a lab study. The outcome indicates that secondary information can be quickly and reliably perceived in the periphery without significantly affecting a primary task. Carefully considering the study results and the participants’ feedback, a concept for a novel visual attentive UI is elaborated. It combines eye tracking with intelligent UI adaptions to make more information perceivable without affecting the primary task performance and thus, use huge displays more efficiently.
Gaze-supported Foot InteractionWhen working with zoomable information spaces, we can distinguish complex tasks into primary and secondary tasks (e.g., pan and zoom). In this context, a multimodal combination of gaze and foot input is highly promising for supporting manual interactions, for example, using mouse and keyboard. Motivated by this, we present several alternatives for multimodal gaze-supported foot interaction in a computer desktop setup for pan and zoom. While our eye gaze is ideal to indicate a user’s current point of interest and where to zoom in, foot interaction is well suited for parallel input controls, for example, to specify the zooming speed. Our investigation focuses on varied foot input devices differing in their degree of freedom (e.g., one- and two-directional foot pedals) that can be seamlessly combined with gaze input.
Gaze-supported Foot InteractionDepthTouch is an installation which explores future interactive surfaces and features elastic feedback, allowing the user to go deeper than with regular multi-touch surfaces. DepthTouch’s elastic display allows the user to create valleys and ascending slopes by depressing or grabbing its textile surface. We describe the experimental approach for eliciting appropriate interaction metaphors from interaction with real materials and the resulting digital prototype.
