HMD Display Settings Adjustment via Visual Acuity Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with visual impairments, such as those wearing corrective lenses or contacts, face difficulties in clearly viewing head-mounted display content due to the lack of adjustable settings that accommodate their visual acuity, requiring frequent manual adjustments.
Innovation Solution
A system and method that utilize sensors, such as EEG probes, to determine a user's visual acuity and automatically adjust display settings like resolution, contrast, and zoom on head-mounted displays to correct for impairments, incorporating a processor and memory to execute this functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If display settings are manually adjusted to correct visual impairments, then visual clarity is improved, but user convenience deteriorates due to frequent adjustments required
Solution Approach 1:
The system automatically detects the user's visual acuity using sensors and adjusts display settings without requiring manual user intervention. The HMD unit performs self-adjustment based on sensor data, eliminating the need for users to constantly modify settings while maintaining optimal visual clarity.
Solution Approach 2:
The system uses sensors to continuously monitor the user's visual acuity and provides feedback to the display adjustment mechanism. This closed-loop feedback system enables automatic real-time adjustments of display parameters based on the user's actual visual state, resolving the contradiction between visual clarity and operational convenience.
2Adaptability or versatility
If display settings are fixed for all users, then device complexity is reduced, but adaptability to individual visual needs deteriorates
Solution Approach 1:
The HMD unit incorporates multiple functional components (sensors, processors, display adjustment mechanisms) into a single universal device that serves both standard display functions and adaptive visual correction functions. This multi-functionality enables the system to adapt to individual user needs without requiring separate devices or complex external equipment.
Solution Approach 2:
The system replaces manual mechanical adjustment mechanisms with automated sensor-based detection and processing. Electronic sensors and algorithms substitute for physical adjustment controls, reducing the need for complex mechanical interfaces while enhancing adaptability to individual visual requirements.
Data Source
AI summary
Apparatuses, methods, systems, and program products are disclosed for adjusting display settings of a head-mounted display. An apparatus includes a processor and a memory that stores code executable by the processor. The code is executable by the processor to receive sensor data from one or more sensors operably connected to a head mounted display (“HMD”) unit while a user wears the HMD unit. The code is executable by the processor to determine a visual acuity of the user based on the sensor data. The code is executable by the processor to adjust one or more display settings of the HMD unit based on the determined visual acuity for the user. The one or more display settings may be adjusted to correct for impairments in the user's visual acuity.
