Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information presentation systems, such as those described in Japanese Unexamined Utility Model Publication S63-1232, are limited in their ability to present multiple different pieces of information in a distinguishable manner, as they primarily focus on single information types and lack effective methods to differentiate between multiple pieces of information through synchronized image and sound outputs.
Innovation Solution
An information presentation system that synchronizes image and sound outputs for each piece of information, using a presentation unit to display virtual images and output sounds in a synchronized manner, with a timing shift between sounds to prevent overlap, allowing users to distinguish multiple pieces of information effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple different pieces of information are presented simultaneously through image and sound outputs, then the quantity of information presented increases, but the distinguishability between different pieces of information deteriorates
Solution Approach 1:
The patent segments the presentation of multiple pieces of information by dividing them into distinct groups, where each group contains information that can be presented simultaneously without confusion. The presentation unit separates information types (e.g., navigation information, vehicle state information, external environment information) into different segments that are managed independently, allowing multiple pieces of information to be presented while maintaining distinguishability through group-based organization.
Solution Approach 2:
The patent introduces temporal dimension to the information presentation by controlling the timing of sound outputs. When multiple pieces of information need to be presented, the system shifts the timing of sound outputs in different groups so that they do not overlap, effectively using time as an additional dimension to differentiate information. This allows the system to maintain distinguishability while increasing the quantity of information presented by utilizing temporal separation.
2Loss of information
If the timing of sound outputs is shifted to prevent overlap, then the distinguishability of multiple sounds improves, but the time required to present all information increases
Solution Approach 1:
The patent implements dynamic timing adjustment where the shift period for sound outputs is not fixed but adaptively determined based on the number and type of information pieces being presented. The control unit dynamically calculates appropriate timing shifts to prevent sound overlap while minimizing total presentation time. This dynamic approach allows the system to optimize between distinguishability and presentation speed according to real-time conditions.
Solution Approach 2:
The system changes the temporal parameter (timing shift period) of sound outputs based on the information presentation requirements. When multiple pieces of information are presented simultaneously, the control unit adjusts the timing shift period to ensure sounds from different groups do not overlap. This parameter change allows flexible adaptation to different information quantities while maintaining distinguishability, reducing unnecessary time delays.
3Adaptability or versatility
If a presentation unit presents multiple forms of information (image and sound), then the versatility of the system improves, but the complexity of synchronizing multiple outputs increases
Solution Approach 1:
The patent introduces a control unit as an intermediary between the information sources and the presentation unit. This control unit manages the complex synchronization tasks by receiving information from multiple sources, determining appropriate presentation timing and forms, and coordinating the image and sound outputs. The intermediary simplifies the overall system architecture by centralizing the synchronization logic, making it easier to manage multiple information forms without proportionally increasing complexity.
Solution Approach 2:
The presentation unit is designed with multi-functionality to handle various types of information (navigation, vehicle state, external environment) through unified image and sound output mechanisms. By creating a universal presentation interface that can adapt to different information types, the system achieves high versatility without requiring separate specialized components for each information type, thereby controlling complexity while maintaining adaptability.

AI summary
An information presentation system according to the present disclosure makes a presentation unit present each of multiple different pieces of information such that an image displayed in a first form and a sound output in a second form are synchronized with each other on an individual basis. The information presentation system also makes the presentation unit shift, when presenting two different pieces of information, selected from the multiple different pieces of information, as two sounds in the second form, a timing to output one of the two sounds by at least a certain period of time with respect to a timing to output the other of the two sounds, in order to prevent the two sounds from overlapping with each other.
