Context-based layout specializes in the placement during which the expertise should be used -- the actions in terms of it and their social contexts. Designers also needs to become aware of that creation of the know-how itself alterations the location; to be able to layout achievable structures, the layout method needs to turn into versatile and adaptive.

Harold Garfinkel (1967), Garfinkel and Harvey Sacks (1970), Hugh Mehan and Houston Wood (1975), and Emanuel A. Schegloff and Sacks (1973) have highlighted the importance of using the resources of the physi- Creating a Sense of Place 33 cal world to establish a common or socially shared meaning.

When people talk, they continuously represent and refer to objects or things to help them achieve some level of common ground or understanding.

Through conversations, experienced persons in a field pass along their knowledge to others by telling stories, answering questions, and discussing information (Garfinkel & Sacks, 1970).
