Roberts, Jasmine.  2018.  Using Affective Computing for Proxemic Interactions in Mixed-Reality. Proceedings of the Symposium on Spatial User Interaction. :176-176.

Immersive technologies have been touted as empathetic mediums. This capability has yet to be fully explored through machine learning integration. Our demo seeks to explore proxemics in mixed-reality (MR) human-human interactions. The author developed a system, where spatial features can be manipulated in real time by identifying emotions corresponding to unique combinations of facial micro-expressions and tonal analysis. The Magic Leap One is used as the interactive interface, the first commercial spatial computing head mounted (virtual retinal) display (HUD). A novel spatial user interface visualization element is prototyped that leverages the affordances of mixed-reality by introducing both a spatial and affective component to interfaces.

We present a study examining the impact of physical and cognitive challenge on reported immersion for a mixed reality game called Beach Pong. Contrary to prior findings for desktop games, we find significantly higher reported immersion among players who engage physically, regardless of their actual game performance. Building a mental map of the real, virtual, and sensed world is a cognitive challenge for novices, and this appears to influence immersion: in our study, participants who actively attended to both physical and virtual game elements reported higher immersion levels than those who attended mainly or exclusively to virtual elements. Without an integrated mental map, in-game cognitive challenges were ignored or offloaded to motor response when possible in order to achieve the minimum required goals of the game. From our results we propose a model of immersion in mixed reality gaming that is useful for designers and researchers in this space.
