We were particularly interested in the performance of the system in two cases. In the first case we wanted to determine the performance of the system when a single activity could have different underlying intentions based on the current context so that returning to our example in Sec. 3 the activity of moving one s hand toward a chess piece could be interpreted as making a move during a game but as cleaning up after the game is over . This case deals directly with the problem that in some situations two apparently identical activities may in fact be very different although the difference may lie entirely in contextually determined intentional component of the activity. In our second case of interest we sought to determine the performance of the system in disambiguating two activities that were in fact different but due to environmental conditions appeared superficially very similar. This situation represents one of the larger stumbling blocks of systems that do not incorporate contextual awareness. In the first set of experiments the same visual data was given to the system several times each with different a context to determine whether the system could use the context alone to disambiguate agents intentions. We considered three pairs of scenarios which provided the context we gave to our system leaving the building on a normal day evacuating the building getting a drink from a vending machine repairing a vending machine and going to a movie during the day going to clean the theater at night. We would expect our intent recognition system to correctly disambiguate between each of these pairs using its knowledge of its current context. The second set of experiments was performed in a lobby and had agents .
