abstract = {The discussion about what can Artificial Intelligence (AI) contribute to games has been running for a long time, however, recent advances in AI show promise of providing new kind of experiences for players and new tools for game developers. In contrast with the traditional Finite State Machine for interaction and response, we consider the scenario of Visual Question & Answering (VQA) - the automatic answering of a textual question about an image. VQA is a tool that can enrich possible answers by combining both visual and textual information. It is also trivial to extrapolate to a game setting without going away from the training domain. In this Work In Progress, we present two original prototypes designed to explore the potential of VQA in games and discuss preliminary findings originated through a Wizard of Oz (WOz) pilot study using VQA to investigate how people interact with such an AI algorithm.},

abstract = {The use of Conversational Interfaces has evolved rapidly in numerous fields; in particular, they are an interesting tool for Serious Games to leverage on. Conversational Interfaces can assist Serious Games' goals, namely in presenting knowledge through dialogue. With the global acknowledgment of the joint crisis in nature and climate change, it is essential to raise awareness to the fact that many ecosystems are being destroyed and that the biodiversity of our planet is at risk. Therefore in this paper, we present Amnesia in the Atlantic, a Serious Game enhanced with a Conversational Interface embracing the challenge of critically engaging players with marine biodiversity issues.},

abstract = {Head-Mounted Display based Virtual Reality is proliferating. However, Visually Induced Motion Sickness (VIMS), which prevents many from using VR without discomfort, bars widespread adoption. Prior work has shown that limiting the Field of View (FoV) can reduce VIMS at a cost of also reducing presence. Systems that dynamically adjust a user’s FoV may be able to balance these concerns. To explore this idea, we present a technique for standard 360° video that shrinks FoVs only during VIMS inducing scenes. It uses Visual Simultaneous Localization and Mapping and peripheral optical flow to compute camera movements and reduces FoV during rapid motion or optical flow. A user study (N=23) comparing 360° video with unrestricted-FoVs (90°), reduced fixed-FoVs (40°) and dynamic-FoVs (40°-90°) revealed that dynamic-FoVs mitigate VIMS while maintaining presence. We close by discussing the user experience of dynamic-FoVs and recommendations for how they can help make VR comfortable and immersive for all.},
