\subsection{Embodied Walking}  Engaging in an action e.g. walking, which is also known as ``activity theory''[REF], requires a continual rebalancing of internal and external knowledge representations. ``Internalisation'', for example learning a skill by watching someone, employs phyiscal props and social cues. However acquired intrenal processes sometimes resort to tools when applied under new circumstances. This is known as ``Externalisation''. The interplay between intrenalisation and externalisation allows humans to develop abilities to adapt, as their circumstances change. This actively unites human perception, action and knowledge (see Figure []).   For a skilled tool-using mnd, a set of external circumstances becomes ``about'' something [Ambient Commons Ref], for example, a pen may invite writing, boots may invite walking, and a book may invite reading. People learn from their settings and as a result they associate the settings with particular states of intent. Intent shapes our perception and as a result discovery of affordances [REF Don Norman Reference]. In the other hand, intent iteself is shaped by the presence of known affordances [REF Don Norman, William Powers,...]   William Powers and Andy Clarks in building perceptive technological control systems, argued that engagament with context provides an active resource, and not just a starting point, for processes of movement, memory, and other applications of executive nature attention [Ambient Commons Ref]. To use the environment as an active resource means that skills can neither be acquired nor applied nor explained without it. Activity theory is attached to the physical tools and situated tasks that interest us also known as intrinsic structure. Intrinsic means within the essential nature of something, for example, passage is intrinsic to a door.   McCullough [Ambient Commons Ref] defines embodiment as
