Abstract: An electronic device is described. During operation, the electronic device may receive information associated with an event, which was detected by a hooking software program while the information was conveyed to an environment (such as an operating system) of the electronic device. For example, the event may be a user-interface operation, such as a click-drag operation, which may be performed using a mouse (and, more generally, using a user-interface device). Moreover, in response to the received information, the electronic device may provide sensory information via the hooking software program. This sensory information may be other than sensory information associated with native operations executed in the environment during a user session prior to the event. Thus, the electronic device may expand the functionality associated with the environment (without modifying software associated with the environment) and, in particular, the functionality associated with events, such as click-drag operations.
