Method and apparatus for recording and analyzing an interaction log

Abstract

An apparatus for recording an interaction log includes an event detector for determining whether a reference event occurred in an interactive system. A state detector detects a parameter indicating a state of the interactive system when the event detector determined that the reference event occurred. A recorder records the parameter detected by the state detector. A latching mechanism latches information to be transferred from an input unit to a processing unit so that the processing unit does not respond to the reference event. A judging mechanism releases the information latched by the latching mechanism when the state detector completes detection. Thus, the state detector detects the parameter in synchronization with occurrence of the reference event. The apparatus also may include a plurality of imaging units and a controller. Each of the imaging units generates an image including graphical items corresponding to reference events recorded in the recorder. The controller receives information designating one of the reference events as a selected event, The controller directs the plurality of imaging units to mark a graphical item that corresponds to the selected event.
