Activity Visualizer provides daily activity visualization of residents in smart homes. It is developed to help annotate residents daily activities, analyze activity recognition algorithms, and resident tracking algorithms in a multi-resident environment.
In a lot of cases, one sensor event needs to be associated with multiple residents.
The current walk-around is having a new resident named "R1;R2" for example to show that the sensor event is associated with both residents.
It would be better if the underlying data structure can support that natively.
