Field of the Invention The present invention relates to an information presenting device in an information processing system using a computer, and more particularly to an information presenting timing control system for making a user effectively recognize presented information.

[0002]

2. Description of the Related Art In a conventional information presentation system, a user continuously operates a specific system on a computer,
I was supposed to be paying attention. Therefore, regardless of the state of the user, the information is presented when the information presentation stage defined in advance as the processing procedure of the system is reached.

In the message output method described in Japanese Patent Application Laid-Open No. 02-213934, the display method is determined based on the appearance frequency of the message, and the message having the low appearance frequency is emphasized to detect the message important to the user. The purpose is to help.

The reception information processing method and apparatus disclosed in Japanese Patent Application Laid-Open No. 02-132946 has an expiration date management table,
The purpose of the present invention is to reduce the maintenance work of received information by automating the process of determining whether the received information is necessary or unnecessary and changing the value of the information over time.

[0005]

In a multitasking computer environment, a user often executes a plurality of processes in parallel. In the situation where one user is performing multiple processes in parallel, it is easy for the user to overlook the information presented by other processes or when the user concentrates on a specific processing task. There is a problem that the presentation may hinder the concentration of the ongoing work or may temporarily suspend the work.

The message output method described in Japanese Patent Laid-Open No. 02-213934 has a problem that information presented by other processes tends to be overlooked when concentrated on a specific process. Further, excessive emphasis display to avoid oversight causes a problem of impairing concentration on processing during operation and lowering work efficiency.

In the reception information processing method and apparatus described in Japanese Patent Laid-Open No. 02-132946, attention is paid to the expiration date, but the content of information to be presented is not considered. There is a drawback that information that requires time to respond is not notified until the expiration date is approaching.

Further, in the conventional method, since the user's state is not taken into consideration, there is a possibility of presenting information of which the deadline is approaching during busy times. There is a problem in that there is a high risk that information presented during busy times may be forgotten because it cannot be dealt with immediately.

In view of the above points, an object of the present invention is to provide an information presenting system which presents information at an appropriate time in consideration of the work state of the user and the importance of the contents of presented information.

[0010]

Means for solving the above-mentioned problems reside in the following three items.

[1] User state estimating means for estimating a user state relating to a user's recognition effect on information presentation,
The information evaluation means for determining the nature of the information to be presented, and the presentation time decision means for deciding the presentation time of the information based on the user status and the nature of the information, and the presentation time according to the user status and the quality of the information It is characterized by controlling.

[2] An abstraction degree determining means for controlling the abstraction degree of the information to be presented based on the presentation time is provided, and the amount of information to be presented is controlled according to the urgency.

[3] User reaction measuring means for recognizing user reaction to information presentation, user reaction evaluation means for evaluating the recognized reaction as an effect of information presentation, and updating of knowledge based on the evaluation result of user reaction. It is characterized by having a knowledge updating means for performing, and refining the knowledge involved in controlling the information presentation time according to the reaction of the user.
