Optical Tag Interaction for WYSIWYG Smart Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face tedious operations when controlling multiple smart home devices through mobile phones, as they need to continuously browse and select options, leading to user rejection due to the complexity of interactions.
Innovation Solution
A method and system using an optical tag for interaction with information apparatus, allowing users to control devices within their field of view by determining the initial position and attitude of a terminal device relative to the optical tag, calculating the imaging position of devices on the screen, and presenting interactive interfaces for easy interaction, which can include screen, voice, or gesture inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users control multiple smart home devices through mobile phone browsing and selection, then device control functionality is achieved, but user operation complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent introduces an optical tag as an intermediary element between the user and the information apparatus. The optical tag contains encoded position and identification information that serves as a mediator, allowing users to access device controls by simply viewing the tag rather than navigating through complex mobile phone interfaces. This intermediary reduces the operational steps from multiple browsing and selection actions to a single visual recognition and interaction.
Solution Approach 2:
The system performs preliminary actions by pre-encoding position information and device identification data into the optical tag before the user arrives. The interactive interface is pre-configured with the relevant control options for the specific information apparatus. When the user views the optical tag, the system has already prepared the context-specific controls, eliminating the need for users to search or navigate through generic device lists during the interaction moment.
2Loss of information
If traditional QR codes are used for device access, then basic identification is achieved, but data coding density and information capacity are limited
Solution Approach 1:
The patent applies parameter changes by transitioning from the static, low-density QR code format to a dynamic optical tag system that utilizes multiple parameters including color variations, light intensity modulation, and temporal encoding. These parameter changes enable the optical tag to encode significantly more information within the same physical space, increasing both data coding density and overall information capacity while maintaining visual recognizability.

AI summary
The present disclosure provides an optical tag-based information apparatus interaction method and system. The method includes: using a terminal device to perform image acquisition on an optical tag at a relative fixed position to an information apparatus so as to determine a position and an attitude of the terminal device relative to the optical tag; determining, in conjunction with a predetermined position of each information apparatus relative to the optical tag, the position of the terminal device relative to each information apparatus; acquiring an imaging position of each information apparatus on a display screen of the terminal device, and displaying an interactive interface of each information apparatus at the imaging position thereof on the display screen, such that an interactive operation can be performed on each information apparatus. The disclosure allows a user to control an information apparatus in a field of view anytime and anywhere, and interact with the device as What You See Is What You Get (WYSIWYG).
