But what was really interesting was how the same sort of loss of freedom made it easier to interpret the scene. We hadn’t planned on it, but we succeeded quite quickly because our strategy had a narrative arc — two discrete “acts”, separated by a small shock. Teams who relied on techniques from traditional charades — symbols and word games — found they had a much harder time. The narrative helped constrain the number of possible interpretations.
Constraining physical space is part of constraining cognitive space in Embodied Cognition terms. When designing tactile maps, it’s in clearly showing the edges that matters. Define the space for learning then guide discovery within that space.
