Personal Display Head Tracking for Automatic Media Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal display systems lack intuitive and user-friendly interfaces for adjusting media display, often requiring complex navigation and failing to account for user movements, leading to eye fatigue.
Innovation Solution
A personal display device that allows users to adjust media display by zooming, masking, and overlaying features, and incorporates sensors to detect user movements, enabling dynamic adjustments that enhance realism and reduce eye strain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the personal display system displays media in the configuration provided by the media source without adjustments, then the device maintains simplicity and portability, but the user cannot customize the viewing experience to reduce eye fatigue
Solution Approach 1:
The system performs preliminary actions by automatically detecting user head movements and pre-adjusting the media display configuration before the user experiences discomfort. The head movement detector continuously monitors user position, and the processor proactively modifies display parameters (zoom, pan, tilt) to maintain optimal viewing angles, preventing eye fatigue before it occurs
Solution Approach 2:
The display system serves itself by automatically adjusting media configuration based on detected head movements without requiring manual user input. The processor receives head movement data from sensors and autonomously modifies display parameters, eliminating the need for complex user interfaces while maintaining optimal viewing conditions
2Adaptability or versatility
If the personal display system includes zoom and pan capabilities, then the user can adjust media display to view different portions, but the interface becomes complex and cumbersome
Solution Approach 1:
The system eliminates manual zoom and pan controls by implementing self-service functionality. The processor automatically adjusts media display configuration based on detected head movements, calculating appropriate zoom levels and pan positions to keep the media centered and optimally sized without requiring any user interface interactions
Solution Approach 2:
The system implements continuous feedback loops where the head movement detector provides real-time data to the processor, which then adjusts media display parameters accordingly. This closed-loop system automatically adapts the display to user positioning, making the versatile zoom and pan capabilities operate transparently without complex controls
3Reliability
If the personal display system ignores user head movements and maintains static display, then the device operates simply, but the user experiences eye fatigue from staring at the same location
Solution Approach 1:
The display system autonomously monitors and responds to user head movements without manual intervention. The head movement detector continuously tracks user position, and the processor automatically adjusts media configuration to maintain optimal viewing angles, ensuring viewing comfort through self-service operation
Solution Approach 2:
The system implements real-time feedback mechanisms where sensor data about head movements is continuously processed to dynamically adjust display parameters. This feedback loop ensures the media remains positioned to reduce eye fatigue by tracking user head position and automatically repositioning the content
Data Source
AI summary
A personal display system with which a user may adjust the configuration of displayed media is provided. The personal display system may include an electronic device operative to provide media to a personal display device operative to display the received media. Using one or more optical and digital components, the personal display device may adjust displayed media to overlay features of a theater, thus giving the user of the personal display device the impression of being in the theater. In some embodiments, the personal display device may detect the user's movements using one or more sensors and may adjust the displayed image based on the user's movements. For example, the device may detect a user's head movement and cause the portion of media displayed to reflect the head movement.
