What is Embodiment, and How Does It Affect the Way We Function?

The way humans learn is very much affected by the fact that we have an embodiment - a physical location in the world, and the ability to change the world (both through physical interaction and through spoken and written communication with other agents). Ideas about the effect of human embodiment can be used to improve the functionality and learning strategies of artificial embodied systems, such as autonomous cars, humanoid robots, exoskeletons, search and rescue robots, etc.. I like to think about the effect of embodiment on our learning in three related ways:
1. We are able to alter the state of the scene we are observing so as to learn aspects of it that are not apparent from a first look. For example, we can move our head to look from a different angle, or squeeze, push or shake an object to investigate it.
2. Humans have a very limited communication bandwidth compared to the internal computation capacity in the brain. This means that we cannot easily perform reasoning together with other humans in the way a computer cluster can share computations. It also means that communication between humans is heavily under-determined and error-prone.
3. This limited bandwidth also means that we are forced to learn from quite few examples, and are extremely good at transfer learning and abstraction of knowledge. For example, it has been shown that a child can learn to recognize an unseen animal, e.g., elephants from a single simple drawing. This indicates that humans use very different visual learning strategies than state of the art Computer Vision systems.
This has implications for how to design artificial embodied systems, especially systems that should collaborate with, learn from, and solve problems together with humans.
In the context of this, I will outline a few of the projects in my group.
