Object Interaction Display Using Camera-Based Code Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing object recognition systems on touch screens require expensive hardware with embedded cameras or optical sensors to detect patterns on objects, and users must often enter passwords or use visible codes for establishing communication links between mobile devices and large format displays, which can be inconvenient and less secure.
Innovation Solution
A system that uses a camera on the object to establish a dedicated link with a host computer without visible codes, employing Direct Contact Camera Codes (DCCC) or wireless transmitters for precise location and orientation detection, allowing for secure and automatic communication between mobile devices and large format displays without the need for passwords or optical sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If a camera or optical sensor is embedded in the touch screen for object recognition, then object detection capability is improved, but hardware cost increases
Solution Approach 1:
The patent introduces an intermediary code (barcode, QR code, or other machine-readable pattern) as a mediator between the object and the camera system. Instead of embedding expensive optical sensors in the touchscreen, the system uses a standard camera to capture images of these codes, which are then decoded to identify and locate objects. This intermediary approach enables object recognition using conventional, low-cost camera hardware.
Solution Approach 2:
The patent uses visual codes (barcodes, QR codes, or custom patterns) as information carriers that can be captured by standard cameras. These codes serve as copies or representations of object identity and location information, allowing the system to recognize objects without needing complex optical sensing hardware embedded in the display.
2Loss of information
If a visible code is placed on the object for recognition, then object identification is improved, but security and convenience deteriorate due to password entry requirements
Solution Approach 1:
The system enables automatic object identification and link establishment through camera-based code recognition. The mobile device automatically captures the code, decodes it, and establishes communication with the display without requiring manual password entry or user intervention. This self-service approach improves both convenience and security by eliminating password transmission requirements.
Solution Approach 2:
The patent replaces manual password entry mechanisms with automated camera-based code recognition. Instead of requiring users to physically type passwords or interact with authentication interfaces, the system uses the camera to automatically capture and process identification codes, substituting mechanical user interaction with automated optical recognition.
3Ease of operation
If PCT (Project Capacitive Technology) is used for touch detection, then touch sensitivity is improved, but optical pattern detection capability is lost
Solution Approach 1:
The patent merges two separate functional systems: a standard capacitive touchscreen for touch detection and a camera system for optical code recognition. By combining these independent subsystems, the display maintains excellent touch sensitivity through PCT while simultaneously gaining object recognition capability through the camera-based code detection, avoiding the need to choose one technology over the other.
