Multi-view Display Controller Head Position Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-view display technologies require viewers to wear glasses or make complex remote control inputs to access additional information, which is not intuitive and can disturb other viewers.
Innovation Solution
A multi-view display controller that generates view information to project media content along multiple directions, allowing additional information to be simultaneously displayed along a selected view direction accessible by simple head movement, eliminating the need for remote control inputs and minimizing disturbance to other viewers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If glasses are used to achieve 3D display effect, then stereo vision is improved, but viewer comfort and simplicity deteriorate
Solution Approach 1:
The patent removes the glasses component from the 3D display system entirely. Instead of using polarized or shutter glasses to achieve stereo vision, the system uses a multi-view display with a lenticular array that directly presents different views to different eye positions, eliminating the need for auxiliary viewing devices and improving viewer comfort.
Solution Approach 2:
The patent replaces the mechanical/optical system of glasses (polarized filters, shutter mechanisms) with a display-based system using a lenticular array and multi-view rendering. This substitution eliminates moving parts and complex optical components from the viewer side, simplifying the system while maintaining stereo vision capability.
2Loss of information
If remote control inputs are used to access additional information, then information access capability is improved, but operation complexity and disturbance to other viewers deteriorates
Solution Approach 1:
The patent adds a spatial dimension to information access by using head position and viewing angle as control parameters. Instead of requiring temporal interactions (remote control button presses), the system allows viewers to access different information layers (media content vs. additional information) by changing their physical position in space, making the interaction more intuitive and simultaneous for multiple viewers.
Solution Approach 2:
The system automatically determines what additional information to display based on the viewer's head position and viewing angle, without requiring explicit commands. The display controller detects viewer position and autonomously selects which information to present, reducing operational complexity while maintaining personalized information delivery.
3Ease of operation
If lenticular array is used for glasses-free 3D, then viewer comfort is improved, but viewing region flexibility deteriorates
Solution Approach 1:
The patent implements a dynamic multi-view display system that can adapt its viewing characteristics. By using multiple pixel columns with different view directions and dynamically controlling which views are active, the system can expand or contract the effective viewing region based on viewer position, maintaining comfort while improving flexibility compared to static lenticular displays.

AI summary
A multi-view display controller (100, 200, 300) generates view information specifying view directions along which media data a media content is to be projected on a multi-view display (2) and specifying a selected view direction along which additional information is to be simultaneously projected as media data of the media content. The multi-view display controller (100, 200, 300) thereby enables an intuitive and efficient communication of additional information to the viewer (5) on the multi-view display (2).
