Solution Overview

Problem

Existing systems struggle to accurately control content display across multiple apparatuses when their spatial relationship is arbitrarily changed, especially without relying on costly retrofit sensors, and differentiate between visible and non-visible displays to users.

Innovation Solution

A system using a camera to capture images of human eyes and process reflections to associate content rendering with the visibility and orientation of displays, allowing for sensor-free control of content distribution based on reflections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple displays are used to display content, then the display area and content distribution capability are improved, but the control complexity and spatial relationship management deteriorate

Engineering Contradiction:
Improvedisplay areaVSAvoidcontrol complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent replaces sensor-based mechanical tracking systems with an optical system using camera and reflection analysis. Instead of using positioning sensors to track display locations and orientations, the system captures images of reflections in the user's eye and processes these reflections to determine display spatial relationships, thereby reducing device complexity while maintaining control capability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces the human eye and its reflections as an intermediary element between the displays and the camera. The reflections in the eye serve as a mediator that encodes spatial information about multiple displays, allowing the system to infer display positions and orientations without direct sensing, thus simplifying the control mechanism

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If positioning sensors are added to displays, then the location and orientation tracking precision is improved, but the manufacturing cost and device complexity increase

Engineering Contradiction:
Improvelocation tracking precisionVSAvoidmanufacturing cost
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent uses optical copying through reflection capture. Instead of directly measuring display positions with sensors, the system captures reflected light patterns from displays in the user's eye and processes these optical copies to determine spatial information. This approach achieves precise location tracking without adding expensive sensors to each display

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The human eye serves as a self-service element that automatically captures and reflects display information. The eye's natural reflective properties are exploited to provide spatial data about displays, eliminating the need for external sensing infrastructure and reducing manufacturing costs while maintaining measurement precision

Inventive Principle:
Principle #25Self-service

3Speed

If sensor-based tracking is used, then the real-time display position detection is improved, but the system cost and complexity increase

Engineering Contradiction:
Improvereal-time detection speedVSAvoidsystem complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The system uses periodic image capture at sufficient frame rates to achieve real-time tracking. By capturing images at regular intervals and processing reflections in each frame, the system maintains real-time detection capability without the continuous operation complexity of sensor-based systems, achieving speed through periodic sampling rather than continuous sensing

Inventive Principle:
Principle #19Periodic action
