We envision Mano-a-Mano to be useful in a variety of dyadic interactions. We anticipate collaborative scenarios that rely on the shared understanding of the 3D layout and motion of virtual objects, such that if one user points at an object, the other user sees them pointing at that object. Of further interest is to what extent Mano-a-Mano gives users the impression of object presence [11]: that is, whether virtual objects appear to be the correct size and distance, even when a number of familiar depth cues are absent or in conflict (e.g., stereoscopy). In short, we would like to know if users “buy” the effect. We make the following contributions:
