CoMap: A Collaborative 3D Sketch Mapping Game to Engage Spatial Communication in Search and Rescue

Search and rescue (SAR) is a complex teamwork environment that requires efficient spatial communication between commanders and field teams with heterogeneous perspectives and asymmetric information. Maps are central artifacts in SAR, yet they are also a space of technological tension due to constantly changing situati…

Sketch2Terrain: AI-Driven Real-Time Terrain Sketch Mapping in Augmented Reality

Sketch mapping is an effective technique to externalize and communicate spatial information. However, it has been limited to 2D mediums, making it difficult to represent 3D information, particularly for terrains with elevation changes. We present Sketch2Terrain, an intuitive generative-3D-sketch-mapping system combini…

Gaze-Guided Narratives: Adapting Audio Guide Content to Gaze in Virtual and Real Environments

Exploring a city panorama from a vantage point is a popular tourist activity. Typical audio guides that support this activity are limited by their lack of responsiveness to user behavior and by the difficulty of matching audio descriptions to the panorama. These limitations can inhibit the acquisition of information a…

The Index of Pupillary Activity: Measuring Cognitive Load vis-à-vis Task Difficulty with Pupil Oscillation

A novel eye-tracked measure of the frequency of pupil diameter oscillation is proposed for capturing what is thought to be an indicator of cognitive load. The proposed metric, termed the Index of Pupillary Activity, is shown to discriminate task difficulty vis-a-vis cognitive load (if the implied causality can be ass…
