Adaptive Information Presentation Based on User Attention Duration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information presentation devices fail to adjust the amount of information based on the user's recognition degree for presentation objects, leading to issues like information overload and discomfort.
Innovation Solution
An information presentation device that includes a recognition-degree determination processor to compare attention time with recognition necessary time for each presentation object, determining the user's recognition degree and adjusting the presentation mode accordingly to prevent excessive information display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is continuously displayed to ensure the user receives all necessary information, then the completeness of information provision is improved, but the user experiences information overload and discomfort
Solution Approach 1:
The patent implements dynamic adjustment of information presentation based on real-time detection of user attention state. The system transitions from static continuous display to dynamic adaptive display, where information is presented only when the user is detected to be in an attentive state, thereby preventing information overload while ensuring completeness
Solution Approach 2:
The system changes the parameter of information presentation timing based on user attention detection. By monitoring attention duration and comparing it with recognition threshold time, the system adjusts when information is displayed, presenting information only when attention duration exceeds the threshold, thus avoiding information overload
2Object-affected harmful factors
If information is displayed only when user attention is detected, then information overload is reduced, but the timing and appropriateness of information delivery becomes challenging
Solution Approach 1:
The system performs preliminary detection of user attention state before delivering information. By continuously monitoring whether the user's line of sight corresponds to the information display area and whether attention duration exceeds the threshold, the system prepares for optimal information delivery timing, ensuring information is presented at the most appropriate moment
Solution Approach 2:
The system uses feedback from attention detection to control information presentation. The attention detection unit continuously monitors user attention, and based on whether attention duration exceeds the threshold, the system feedback-controls when to present information, ensuring timely and appropriate delivery without overload

AI summary
There are provided an attention-time measuring unit that specifies an attention area from a user's visual line and measures an attention time T that is a time period during which the attention area is overlapping with a display area indicated by presentation information acquired by a presentation-information acquiring unit; a minimum recognition-necessary-time specifying unit that specifies, from a type of a presentation object indicated in the presentation information, a minimum recognition-necessary time Tmin that is a minimum necessary time for recognizing the content of the presentation object; and a user's recognition-degree determination unit that makes a comparison between the time T and the time Tmin, and determines from that comparison result, a recognition degree of the user for the presentation object; wherein a presentation-mode selecting unit presents the presentation object in a presentation mode corresponding to the recognition degree determined by the determination unit.
