Abstract
A warning timer adapted for use in an interactive data processing system which generates an alarm when a user receives output at an input/output device when he or she is not likely to be paying attention to the input/output device. The user is assumed to be paying attention for a specified amount of time after he or she last sent a request to a computer or received a response from the computer. The specified amount of time corresponds to the length of the user's attention span. The warning timer operates as follows. When the user receives a response, it calculates the amount of time that has elapsed since the user last sent a request or received a response. If the elapsed time exceeds the specified amount of time, it generates an alarm to alert the user.
