“Context varies according to application constraints, taking into account the way users act in the environment, as well as the interfaces to interact with.” (Afyouni et al, 2012).
This problem is allied to problem A6. Because of their application and composition, indoor environments will differ. Before automated acquisition and modelling can begin this difference has to be accounted for and operator. Typically the operator will choose appropriate hardware and software parameters.
An example for this might be accounting for differences in lighting conditions or identifying the context of an environment based on the objects contained in the environment. The challenge is to discover the context of environments Automatically so that the devices used for acquisition and modelling become universal.
