SHMUC prototype > C_Activities_In_Wrong_Places_Use_Cases
Performing an action in the wrong place may endanger people (e.g., jumping on the bed) or signify that something has gone wrong (e.g., lying on the kitchen floor). The following scenarios will discuss how the spatial properties of an activity can help to identify abnormal behaviour.
C1 Lying Down in the Kitchen
Detecting abnormality of activity spatial property requires the spatial data must be stored by the system and attached to behaviour. In comparison to the previous use cases, this one is more static in that the information does not change frequently. A further issue that may arise is that if the system had sufficient sensors to recognise where somebody was lying, and information about how they got there (carefully or abruptly) then it could identify the need for an urgent response to a fall. Without the latter information, the best that it can do is to recognise a behaviour that is seen frequently but where the location is unexpected.
