Travel Route Map Display for Immersive Image Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capturing and playback devices fail to provide an immersive experience during slide shows by not effectively simulating the travel route and location information, making it difficult for viewers to feel as if they are experiencing the travel process.
Innovation Solution
An image capturing device equipped with a GPS receiving unit, triaxial geomagnetic sensor, and triaxial acceleration sensor that determines travel means and direction, generating travel route data and displaying a moving mark on a map to simulate the travel experience, allowing for accurate positioning and playback of captured images along the route.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional slide show function is used to display captured images, then images can be displayed sequentially, but the viewing experience cannot make the viewer feel as if they actually experienced the travel
Solution Approach 1:
The patent transitions from a conventional 2D slide show display to a 3D spatial representation by displaying captured images on a map view that shows the actual travel route. The map display unit presents geographic coordinates and route information, creating a spatial dimension that immerses viewers in the travel experience by showing where images were captured in real geographic space rather than just sequential frames
Solution Approach 2:
The patent introduces a map display as an intermediary between the captured images and the viewer. The map serves as a mediator that contextualizes images within their geographic and temporal framework, allowing viewers to understand the travel route and location information, thereby enhancing the immersive experience without directly modifying the image display itself
2Loss of information
If position data is added to image data to record travel route information, then location information is preserved, but the slide show still cannot provide sufficient enjoyment to make viewers feel they experienced the travel
Solution Approach 1:
The patent utilizes the preserved position data by projecting it onto a 2D map display that represents 3D geographic space. This dimensional transformation allows the position information to be visualized as a travel route with spatial context, enabling viewers to see the actual path taken and locations where images were captured, thereby creating an immersive travel experience from the preserved location data
Solution Approach 2:
The patent creates a virtual copy of the travel route by plotting captured image positions on a digital map. This virtual representation replicates the actual travel path and locations, allowing viewers to experience the travel route through the map display without physically being present, thus enhancing immersion while utilizing the preserved position information
3Speed
If a mark moves on a map to indicate travel position, then travel route is visualized, but the movement speed and smoothness of the mark may affect display quality
Solution Approach 1:
The patent implements dynamic control of the mark's movement speed on the map by adjusting it according to the actual travel speed derived from position data. The mark moves faster when the captured images indicate faster travel and slower when travel was slower, creating a realistic and smooth visualization of the travel experience that adapts to the actual pace of the journey
Solution Approach 2:
The system uses feedback from the captured images and their associated position data to control the mark's movement. By analyzing the time and location information from sequentially captured images, the system adjusts the mark's speed and positioning on the map to accurately reflect the actual travel pattern, ensuring smooth and realistic visualization of the travel route

AI summary
A playback display device including: a display unit; a data storage unit which stores data representing a travel route and a plurality of pieces of image data each associated with an image capturing place; a movement display control unit which displays a mark moving on a map displayed on the display unit based on the data representing the travel route; and an image playback unit which displays image data when, while the movement display control unit displays the mark moving on the map, a displayed position of the mark matches a corresponding position of the image capturing place associated with the image data.
