I have no sense of direction. Seriously, I once walked around a circular plaza one and a half times before realizing that I was retracing my steps. I always imagine that functional humans have a sort of navigator in their head that allows them to orient themselves constantly and keep track of where they are now relative to where they were before. I'm not like that. I still get lost in my office building.
Which is why I love love love augmented reality, especially as it applies to mapping services.
The "uncanny valley" is a hypothesis that as a robot is made more humanlike, the emotional response from a human being to the robot will become increasingly positive and empathic, until a point is reached beyond which the response quickly becomes that of strong repulsion. The phenomenon can be explained by the notion that, if an entity is sufficiently non-humanlike, then the humanlike characteristics will tend to stand out and be noticed easily, generating empathy. On the other hand, if the entity is "almost human", then the non-human characteristics will be the ones that stand out, leading to a feeling of "strangeness" in the human viewer.
