Head-Mounted Display Voice Control Reducing Operating Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display (HMD) and eyewear devices face challenges in reducing the operating load and wearing load on users, which can lead to increased user experience (UX) issues due to the need for arm movement and display screen manipulation.
Innovation Solution
An information processing apparatus that sets a display mode based on the user's head posture, using posture information to adjust the display settings and reduce the need for manual operation, thereby enhancing user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an operation device such as a button is provided in the HMD or eyewear, then the user can perform desired operations, but the movement of the arm and manipulation of the display screen increase operating load and wearing load
Solution Approach 1:
The patent replaces mechanical button operations with voice recognition technology. The voice recognition unit detects user commands through speech, converting acoustic signals into operational instructions without requiring physical manipulation of buttons or display elements. This substitution eliminates the need for arm movement and manual interaction, directly reducing operating load while maintaining device functionality.
Solution Approach 2:
The patent introduces a voice recognition unit as an intermediary between the user and the device operations. Instead of direct mechanical interaction, the user's voice serves as the medium to transmit commands to the control unit, which then executes the desired operations. This intermediary mechanism reduces the physical burden on the user while preserving full operational capability.
2Ease of operation
If the display screen is moved by operation, then the user can access different functions, but this increases the operating load
Solution Approach 1:
The patent enables preliminary action by allowing users to issue voice commands that pre-determine the desired display position or function. The control unit interprets the voice command and directly navigates to the required screen position or function without requiring sequential manual scrolling or button pressing. This preliminary specification of intent through voice reduces the time and effort needed to access functions.
Solution Approach 2:
The patent replaces the mechanical interaction of moving the display screen through button presses with voice-based control. The voice recognition unit captures the user's intent, and the control unit automatically adjusts the display position accordingly. This substitution eliminates the time-consuming manual manipulation while maintaining full access to all display functions.
3Ease of operation
If voice recognition technology is used, then the operating load is reduced, but the device requires additional processing units and software
Solution Approach 1:
The patent integrates the voice recognition unit into the existing control unit, allowing the same processor to handle both traditional button inputs and voice commands. This multi-functionality approach enables the device to operate in multiple modes (manual and voice-controlled) without requiring completely separate processing systems, thereby reducing the overall increase in device complexity while maintaining the benefits of reduced operating load.
