Effective blended reality systems must work by creating harmony through using appropriate contexts and thus creating optimal presence states. Contextual cues about colour, material, shape, size, texture, and weight configuration of the physical object provide possible improvement in a blended reality environment. Haptic feedback helps users feel a degree of tangibility, a convergence between the physical and virtual. But while haptic feedback can contribute, tangibility is not the same as haptics, in the same way that experienced presence is not the same as technologically-inducedimmersion (Waterworth et al. 2015). Tangible presence and co-presence are about supporting a natural flow of action andalmostunconscioussenseofthehereandnow,withinshareablecontexts.Thisis the potential experience of those interacting within blended reality spaces. The next chapter (Chap. 6) provides several illustrative examples of the human-experiential design of such blended reality spaces.
