Collaborative game-based learning environments offer the promise of combining the strengths of computer-supported collaborative learning and gamebased learning to enable students to work collectively towards achieving problemsolving goals in engaging storyworlds. Group chat plays an important role in such environments, enabling students to communicate with team members while exploring the learning environment and collaborating on problem solving. However, students may engage in chat behavior that negatively affects learning. To help address this problem, we introduce a multidimensional stealth assessment model for jointly predicting students' out-of-domain contributions to group chat as well as their learning outcomes with multi-task learning. Results from evaluating the model indicate that multi-task learning, which simultaneously performs the multidimensional stealth assessment, utilizing predictive features extracted from in-game actions and group chat data outperforms single-task variants and suggest that multi-task learning can effectively support stealth assessment in collaborative game-based learning environments.

Large multi-projector displays allow users to be immersed in the data at a grand scale without wearing AR/VR headsets. There has been tremendous advancement in automated projection mapping that uses multiple feedback cameras to stitch and blend images from multiple projectors on curved surfaces of different shapes and sizes. Yet, there is still no easy way to interact with such displays. In this paper, we present a scalable technique that uses the same feedback cameras used for projection mapping to enable multi-user interaction with these displays using multi-colored laser-pens. We also devise methods to achieve the projection mapping and the laser based interaction in the presence of ambient light. This results in an interactive multi-projector system that can be set up and used in an interactive manner in regular illuminated conditions without any disruptions.
