Solution Overview

Problem

Existing display control methods require users to manually operate a PC to determine and instruct operation target devices, which is time-consuming, especially when multiple devices need to be controlled sequentially.

Innovation Solution

A control method and device that receive imaging data from a camera setting the user's visual field, capture identification images on a display surface, determine the operation target device based on the identification information, and transmit operation signals to the selected device, allowing for automatic device selection and control without manual PC operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If manual operation is used to determine and control multiple display devices, then device control accuracy is maintained, but operation time increases significantly

Engineering Contradiction:
Improveoperation timeVSAvoidautomatic control accuracy
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical operation with an imaging-based automatic identification system. The imaging device captures images of display devices, and the image processing section automatically extracts identification information from these images to determine operation target devices, eliminating the need for manual selection operations.

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

Solution Approach 2:

The display devices automatically present their identification information through displayed images, and the system automatically processes these images to identify and select the operation target devices. This self-service mechanism allows the system to automatically determine which devices the user intends to control based on the captured images.

Inventive Principle:
Principle #25Self-service

2Productivity

If multiple operation target devices are controlled sequentially through manual operation, then individual device control precision is maintained, but productivity decreases

Engineering Contradiction:
Improvedevice control efficiencyVSAvoidnumber of operation steps
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The system performs preliminary identification of operation target devices by capturing images and extracting identification information before the actual control operation begins. This preliminary action allows multiple devices to be pre-selected and prepared for control, enabling batch processing rather than sequential individual control.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent merges the identification and selection of multiple operation target devices into a single imaging and processing operation. Instead of separately identifying and selecting each device individually, the system captures one or more images containing identification information of multiple devices and processes them together to determine all operation target devices simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

3Speed

If automatic image-based identification is implemented, then operation speed increases, but device complexity increases

Engineering Contradiction:
Improvedevice selection speedVSAvoidsystem structure complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The imaging device serves multiple functions: it captures images of display devices for identification purposes, and the same imaging capability is used to extract identification information from displayed images. This multi-functional use of the imaging device reduces the need for separate specialized components for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces an image as an intermediary carrier that conveys identification information from the display device to the control system. Instead of direct electronic communication or complex hardware interfaces, the identification information is transmitted through visual display and image capture, simplifying the interaction between devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A control method for a display device executed by a control device includes receiving imaging data generated by an imaging device, which sets at least a part of a visual field of a user as an imaging target region, capturing an identification image displayed on a display surface by the display device, the identification image including identification information for identifying the display device, determining, as an operation target device, the display device indicated by the identification information included in the imaging data, and transmitting an operation signal based on operation by the user to the operation target device.
