Due to constant information overload in knowledge work we are working towards a self-(re-)organizing, especially forgetful, context-sensitive assistance system (cSpaces). Here, we present a study on task (context) switching in which participants were supported by an early version of our system. Participants were assigned to either a control group with no, a group with context-insensitive or a group with context-sensitive support by the assistance system. Activities were logged and analyzed regarding group-dependent differences in task resumption lags. Participants supported by our assistant took less time to resume a former activity after context switching than participants with no support. This result provides initial evidence that context-sensitive, intelligent systems like cSpaces are able to effectively support knowledge workers.
