  • Patent number: 11099866
    Abstract: An apparatus stores status information and workload information for each task executed by a user. The apparatus detects, based on the status information, completion of a first task, and withholds notification of first help information related to software selected based on a usage state of the software in the first task. The apparatus detects, based on the status information, completion of a second task after completion of the first task, and calculates, based on the workload information, an index value indicating a total workload of completed tasks including the first and second tasks. When the index value is greater than a threshold, the apparatus allows providing the user with notification of the first help information and second help information related to the software selected based on a usage state of the software in the second task; otherwise the apparatus withholds notification of the first and second help information.
