What We Measure in Mixed Reality Experiments

There are many potential measures that one might use when evaluating mixed-reality experiences. In this position paper I will argue that there are various stances to take for evaluation, depending on the framing of the experience within a larger body of work. I will draw upon various types of work that my team has been involved with in order to illustrate these different stances. I will then sketch out some directions for developing more robust measures that can help the field move forward.
