Head Mounted Display Extended Desktop via Virtual Copy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional multi-display systems are limited by suboptimal portability and high resource consumption due to the need for multiple physical displays, which restricts their use to fixed locations and incurs significant costs.
Innovation Solution
A multi-display system that combines a physical display with a head-mounted display (HMD) providing a virtual display, allowing computer-generated information to be presented as an extended desktop by generating virtual displays using generation logic and presenting them on a see-through display, enabling users to view virtual information alongside real-world scenes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple physical displays are used to create an extended desktop, then the display area is increased and work efficiency is improved, but the portability deteriorates and the system becomes restricted to fixed locations
Solution Approach 1:
The patent uses a head-mounted display to create a virtual copy of a physical display, allowing the extended desktop functionality to be ported without requiring additional physical displays. The HMD presents a virtual display that mirrors or extends the physical display content, enabling mobile access to multi-display capabilities.
Solution Approach 2:
The patent transitions from a two-dimensional physical display plane to a three-dimensional virtual display experience by projecting the extended desktop onto the user's field of view through the HMD, adding spatial depth and mobility to the multi-display experience.
2Area of stationary object
If multiple physical displays are deployed to provide extended desktop functionality, then the display area increases, but the resource consumption and costs increase significantly
Solution Approach 1:
Instead of procuring and powering additional physical displays, the system creates a virtual replica using the HMD's display capabilities. This virtual copy provides the same extended desktop functionality without the material and energy costs of physical hardware.
Solution Approach 2:
The HMD serves multiple functions: it acts as both the primary display device and the extended display device, eliminating the need for separate physical displays. The same hardware platform provides both the base display and the extended virtual display functionality.
3Loss of information
If traditional multi-display systems are used, then more computer-generated information can be displayed, but the system complexity and setup requirements increase
Solution Approach 1:
The patent merges the physical display and HMD into a unified multi-display system managed by a single computing device. The computing device coordinates both the physical display output and the HMD virtual display content, simplifying the system architecture compared to managing multiple independent physical displays.

AI summary
A head mounted display for displaying computer-generated information in conjunction with a physical display of a computer system is provided. The head mounted display includes a generation logic, a see through display, and a presentation unit. The generation logic is used to generate at least one virtual display. The presentation unit is used to present the at least one virtual display on the see-through display. The see-through display is configured to enable a user of the head mounted display to view the at least one virtual display and the physical display in a real-world scene. The at least one virtual display is presented on the see-through display as an additional object in the real-world scene, and the at least one virtual display is used in conjunction with the physical display to present the computer-generated information in an extended desktop from a visual perspective of the user.
