Dynamic Display Mode Switching for Head-Mounted Display Operability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted displays (HMDs) face challenges in maintaining operability accuracy when users are in different states, such as stopping or moving, leading to degraded usability due to difficulties in inputting operations effectively.
Innovation Solution
An information processing apparatus that dynamically switches input methods based on user activity states by acquiring information about the user situation and determining a display mode to optimize operation unit inputs accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed display mode is used in HMD, then device complexity is reduced, but operability accuracy degrades when user activity state changes
Solution Approach 1:
The patent applies dynamics by making the display mode changeable according to user activity state. The display control unit dynamically switches between first display mode (for low activity) and second display mode (for high activity) based on detected user activity levels, allowing the system to adapt to varying operational conditions while maintaining input accuracy
Solution Approach 2:
The patent implements feedback by detecting user activity state and using this information to adjust display mode. The activity detection unit continuously monitors user activity and provides feedback to the display control unit, which then adjusts the display mode accordingly, creating a closed-loop system that maintains optimal operability
2Ease of operation
If display mode adapts to user activity state, then operability is improved, but information processing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the display mode into distinct first and second modes tailored to different activity levels. Rather than implementing a continuous complex adaptation system, the patent segments the solution into discrete modes that are switched based on activity state, simplifying the overall processing requirements while maintaining adaptability
Solution Approach 2:
The patent implements multi-functionality by designing a display control unit that can operate in multiple display modes using the same hardware resources. The same display unit serves different functional requirements (first display mode for low activity, second display mode for high activity) without requiring separate processing systems

AI summary
An information processing apparatus including circuitry that acquires information associated with a user situation, determines a display mode based on the information associated with the user situation, and enables an operation unit to receive a user input based on a target displaying in the determined display mode.
