Mobile Terminal for Location, Time, and Direction-Based Image Recall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image presentation methods, such as those described in Patent Document 1, struggle to effectively recall user memories by considering various conditions like season, time, and direction angle, and lack a method to highlight relevant images during display.
Innovation Solution
A mobile information terminal and information presentation system that captures and stores images with date, time, location, and direction angle information, allowing users to set personalized search conditions and display related images based on current terminal status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If images are selected based only on current location and imaging location, then the image selection process is simple, but the user cannot effectively recall memories because seasonal, temporal, and directional context is lost
Solution Approach 1:
The patent segments image selection criteria into multiple independent dimensions: location information, date and time information, and direction angle information. Each dimension can be processed and stored separately, then combined to provide comprehensive memory recall context without overwhelming system complexity
Solution Approach 2:
The patent adds new dimensions to the traditional location-based image selection by incorporating temporal dimensions (season, month, day, time) and spatial orientation dimension (direction angle). This multi-dimensional approach enables more accurate memory recall while maintaining manageable complexity through modular information structure
2Ease of operation
If all selected images are displayed uniformly, then the display process is simple, but images of particular interest to the user cannot be highlighted
Solution Approach 1:
The patent applies local quality by differentiating display characteristics for different images based on their relevance to current terminal information. Images that closely match current location, time, and direction are displayed with higher prominence or different visual characteristics, while less relevant images use standard display, preserving user interest information without complicating the overall display process
Data Source
AI summary
When storing captured image data in an information server, a mobile information terminal transmits related information (date and time information, location information, direction angle information, information of a distance to a subject, and user identification information) at the time of imaging to the information server. In addition, when making a request for the image data stored in the information server, current terminal information and image search conditions describing image data replay conditions are transmitted to the information server. The information server searches for corresponding image data based on the current terminal information and the image search conditions and transmits the corresponding image data to the mobile information terminal. The mobile information terminal displays the received image data on the display unit as a related image. Therefore, a user can effectively recall the memories, such as a situation or impression at the time of imaging.
