Wearable Terminal Visible Area Detection for Remote Instruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable terminal devices used in virtual and mixed reality environments face challenges in effectively displaying instructional images within the user's visible area, leading to situations where these images may be outside the user's field of view, resulting in a lack of awareness for the user.
Innovation Solution
The wearable terminal device includes a processor that detects the user's visible area and displays instructional images within it, while issuing notifications when these images are outside the visible area, ensuring the user is aware of their presence through visual or auditory cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If instructional images are displayed at fixed positions in the virtual space, then the images can be clearly presented, but the images may fall outside the user's visible area, reducing user awareness
Solution Approach 1:
The system dynamically adjusts the position of instructional images based on the user's head orientation and visible area. The image position is not fixed but changes in real-time to ensure it remains within the user's field of view, resolving the contradiction between clear presentation and visibility.
Solution Approach 2:
The system continuously monitors the user's visible area through head tracking and provides feedback by adjusting image placement. When an instructional image approaches the boundary of the visible area, the system repositions it to maintain optimal visibility, ensuring user awareness without requiring manual adjustment.
2Loss of information
If the wearable terminal device provides continuous notifications to ensure instructional images are visible, then user awareness is improved, but device complexity increases
Solution Approach 1:
The system implements a feedback mechanism that monitors instructional image positions relative to the user's visible area and triggers notifications only when necessary. This selective notification approach maintains user awareness while avoiding excessive notifications that would increase perceived device complexity.
Solution Approach 2:
The notification system uses visual cues such as color changes or highlighting to indicate when instructional images are outside the visible area. This intuitive visual feedback method conveys position information clearly without requiring complex notification mechanisms.
Data Source
AI summary
A wearable terminal device is configured to be used by being worn by a user. The wearable terminal device includes at least one processor. The at least one processor detects a visible area for the user inside a space and causes a display to display an instructional image located inside the visible area. When there is an instructional image located outside the visible area, the at least one processor issues a first notification making the user aware of the existence of the instructional image. As a result of this first notification being issued, the user of the wearable terminal device is able to notice the existence of the instructional image generated by an instruction given by a remote instructor.
