Abstract:
1. A memory recall assistance apparatus for providing memory recall assistance to a user by a computer, the user operating an avatar in a virtual world divided into a plurality of blocks each provided with a unique identifier (ID), the apparatus comprising: search means of searching an activity record database (DB), including recorded activity datasets, to find an activity dataset containing an entered block ID of the avatar, the activity datasets each obtained by recording data on an activity of an avatar including an event content, a movement history and a repetition count of the activity; determination means for determining whether the found activity dataset is appropriate for the memory recall assistance; and display means for displaying, on a display of the computer, the activity dataset determined as appropriate for the memory recall assistance, wherein the determination means includes means for calculating an importance score of the activity dataset from the event content and the repetition count and means for determining that the activity dataset is appropriate for the memory recall assistance if the importance score is greater than a predetermined value, wherein the display means includes means for displaying the movement history of the activity dataset near the avatar and means for displaying the event content of the activity dataset near the avatar, wherein the virtual world is shared by a server computer and a plurality of client computers, the activity record DB is recorded in the server computer, and wherein a search means, a determination means, and a display means operate by using activity datasets of the activity record DB to assist the user to recall memory according to an activity dataset of another client computer, and wherein the memory recall assistance based on activity datasets of the other client computers is distinctively displayed with an attribute different from that of the memory recall assistance based on its own activity dataset.
