Solution Overview
Problem
Existing technologies face challenges in easily creating content that utilizes position information, particularly due to inaccuracies in GPS data which can lead to incorrect detection of content region entry and exit points, resulting in unintended sound playback or overlap issues.
Innovation Solution
An information processing apparatus with a first acquisition section for map information, a setting section to designate content regions, a storage to associate content data with map information, and a display controller to superimpose content regions on maps, along with a generator to calculate accuracy information based on GPS data, ensuring accurate region setting and minimizing overlap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If content regions are set based on map information without considering GPS accuracy, then the creation process is simple and fast, but position information accuracy deteriorates leading to incorrect region entry/exit detection
Solution Approach 1:
The system performs preliminary actions by pre-calculating and storing accuracy information for multiple regions before content creation. This includes pre-determining accurate region boundaries by comparing map information with actual position sensor data, so that when content is created, the accurate boundary information is already ready for immediate use, eliminating the need for time-consuming real-time calculations.
Solution Approach 2:
The system creates a copy of the map information and overlays it with actual position sensor data to generate corrected boundary information. This copying process allows the system to preserve the original map structure while incorporating real-world position accuracy, enabling fast content creation based on accurate regional boundaries without reprocessing the entire map each time.
2Device complexity
If GPS position information is used directly for region detection, then the system is simple to implement, but reliability deteriorates due to GPS inaccuracies causing unintended sound playback
Solution Approach 1:
The system introduces an intermediary layer between the simple GPS position information and the content playback control. This intermediary is the accuracy-corrected boundary information that mediates between raw GPS data and region detection logic, filtering out GPS inaccuracies while maintaining system simplicity. The intermediary layer processes GPS coordinates through pre-calculated accuracy data to produce reliable region detection without complex real-time computation.
Solution Approach 2:
The system implements feedback by using position sensor data to correct and verify map-based region boundaries. Actual position sensor measurements are fed back into the system to adjust and validate the boundaries, creating a feedback loop that continuously improves detection reliability. This feedback mechanism ensures that region detection remains reliable even when GPS data fluctuates, preventing unintended sound playback.
3Area of stationary object
If multiple content regions are set close together to maximize coverage, then coverage area increases, but harmful factors worsen due to overlap causing unintended sound playback
Solution Approach 1:
The system applies local quality by adjusting region boundary definitions according to local GPS accuracy characteristics. In areas with high GPS accuracy, boundaries can be set closer together to maximize coverage. In areas with poor GPS accuracy, boundaries are expanded to prevent overlap and unintended sound playback. This local adaptation allows optimal coverage while preventing harmful overlaps in specific locations.
Solution Approach 2:
The system implements beforehand cushioning by pre-expanding region boundaries in areas known to have poor GPS accuracy. This creates a buffer zone that compensates for potential GPS errors before they can cause harmful effects. By anticipating areas of poor signal quality and pre-adjusting boundaries accordingly, the system prevents overlap and unintended sound playback before it occurs, while still maintaining maximum coverage where GPS is reliable.

AI summary
An information processing apparatus according to an embodiment of the present technology includes a first acquisition section, a setting section, a storage, and a display controller. The first acquisition section acquires map information. On the basis of designation of a region that is performed by a user, the setting section sets a content region with which content data is associated. The storage stores therein the set content region and the map information in a state of being associated with each other. The display controller causes the content region to be superimposed on the map information to be displayed. This makes it possible to easily create content that uses position information.
