VR Display Range Guide for Video Boundary Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In video content with wider ranges than human viewing angles, users face difficulties in distinguishing between displayed and non-displayed areas, particularly when non-video ranges are displayed, leading to confusion about the video range boundaries and posture requirements.
Innovation Solution
An electronic device with a display controlling unit that changes the display range and provides a guide indicating the positional relationship between video and non-video ranges, allowing for smoother navigation and recognition of valid video ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display range is moved beyond one end of the valid video range to display the non-video range, then the valid video range at the other end can be displayed, but the user cannot discern whether the video is not being displayed due to the non-video range or due to some kind of abnormality in the display process
Solution Approach 1:
A guide object is introduced as an intermediary element between the display range and the non-video range. This guide object visually indicates the boundary between video and non-video ranges, allowing users to understand that the absence of video content is intentional (due to being in a non-video range) rather than an error. The guide object mediates the information gap by providing contextual information about the display state.
2Device complexity
If the non-video range beyond the one end of the valid video range is hidden, then the display appears cleaner, but the user cannot discern whether the display range is not changed because an end of the valid video range has been reached or because some kind of abnormality has occurred
Solution Approach 1:
The guide object serves as an intermediary that provides status information without adding complex visual elements to the main display. It subtly indicates the boundary between video and non-video ranges, enabling users to understand the display range status without creating visual clutter or increasing overall display complexity.
Solution Approach 2:
The guide object provides visual feedback to users about the current display state. When the display range reaches the end of the valid video range, the guide object appears to indicate this boundary, giving users feedback about the system state without requiring them to interpret complex visual changes or make assumptions about why the video stopped.
3Adaptability or versatility
If the non-video range is wide, then the valid video range can be fully contained, but the non-video range must be displayed for a long period of time requiring difficult postures and making it difficult to discern which range is being displayed
Solution Approach 1:
The guide object extracts and separates the information about video range boundaries from the main video content. By placing the guide object at the boundary between video and non-video ranges, it allows users to quickly identify the valid video range without having to interpret the entire wide non-video range, reducing the cognitive and physical effort required to understand which range is being displayed.

AI summary
An electronic device according to the present invention includes at least one memory and at least one processor which function as: a display controlling unit configured to perform control so as to display a range of a part of a VR content as a display range on a display, and configured to be able to change a position of the display range, wherein the display controlling unit performs control so that, when a part of a VR content that is a display target is a non-video range, a range of a part of the VR content is displayed as a display range and a guide indicating a positional relationship between a video range and the non-video range of the VR content is displayed.
