Head-Mounted Display Attitude-Based Information Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted display apparatuses switch information unexpectedly when the user's attitude changes, making it difficult for the user to maintain and view important information that takes time to grasp, leading to inconvenience and discomfort.
Innovation Solution
A head-mounted display apparatus equipped with an attitude sensor, manipulation sensor, and processor that allows users to intentionally switch or maintain information display based on their actions, using predetermined manipulations to prevent automatic switching during attitude changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If information is switched automatically according to attitude change, then information presentation adaptability is improved, but information stability deteriorates
Solution Approach 1:
The system dynamically adjusts information display based on detected attitude changes. When attitude change is detected, the system switches between different information screens (e.g., first screen showing notification, second screen showing detailed information). This dynamic adaptation allows the display to respond to user context while maintaining stability through controlled transition mechanisms.
Solution Approach 2:
The system uses attitude sensors to detect head orientation and provides feedback by automatically switching displayed information accordingly. The feedback loop continues until a manipulation input is received, at which point the system transitions to a stable state where information remains fixed regardless of further attitude changes.
2Ease of operation
If information is switched according to attitude change, then user operation convenience is improved, but information reliability deteriorates
Solution Approach 1:
The system provides self-service by automatically detecting attitude changes and switching information displays without requiring explicit user commands. This convenient automatic operation is combined with a reliability mechanism where manipulation input freezes the display state, ensuring that once the user indicates they are viewing information, it remains stable and reliable for continued reading.
3Speed
If automatic switching is enabled, then information presentation speed is improved, but user control precision deteriorates
Solution Approach 1:
The system performs preliminary automatic switching based on attitude detection to present information quickly. However, it prepares for user intervention by monitoring for manipulation inputs. When such input is detected, the system immediately transitions to a controlled state where further switching is prevented, allowing the user to review information at their own pace without rushed automatic transitions.
Data Source
AI summary
A head-mounted display apparatus worn on the head of a user and a method for controlling the head-mounted display apparatus are disclosed. The head-mounted display apparatus includes a gesture sensor that detects a swipe gesture manipulation that indicates a direction, the swipe gesture manipulation being performed in a manipulation space, a display, a processor, and a memory storing a program. The program, when executed by the processor, executes a switching operation, in which first display information to be displayed on the display is switched to second display information according to the direction indicated by the swipe gesture manipulation detected by the gesture sensor.
