Solution Overview
Problem
Existing electronic devices lack an efficient method to determine and transmit two-dimensional or three-dimensional coordinates of a control device relative to a surface, limiting their ability to accurately control pointer objects based on distance from the ground.
Innovation Solution
A method that measures the distance between an electronic device and a surface, transmitting two-dimensional coordinates if the distance is below a threshold and three-dimensional coordinates if it exceeds the threshold, allowing for the determination and processing of movement data to display corresponding pointer objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If three-dimensional coordinates are always transmitted to indicate control device position, then position accuracy is improved, but data transmission complexity increases
Solution Approach 1:
The patent dynamically adjusts the coordinate system dimension (2D or 3D) based on the distance between the control device and ground. When the device is close to the ground (distance < threshold), 2D coordinates are used; when farther away (distance >= threshold), 3D coordinates are used. This dynamic adaptation resolves the contradiction by matching data complexity to actual spatial requirements.
Solution Approach 2:
The patent changes the parameter of coordinate dimension (from 2D to 3D) based on the distance parameter. By monitoring the distance between the control device and ground, the system switches between different coordinate representations, optimizing data transmission while maintaining necessary position accuracy for each scenario.
2Productivity
If two-dimensional coordinates are transmitted when distance is small, then data transmission efficiency is improved, but position representation accuracy deteriorates for distant objects
Solution Approach 1:
The system dynamically selects the appropriate coordinate dimension based on real-time distance measurements. For close-range interactions, 2D coordinates provide sufficient efficiency and accuracy. For far-range interactions, the system transitions to 3D coordinates to maintain position representation accuracy, thus dynamically balancing efficiency and precision requirements.
Solution Approach 2:
The patent applies different coordinate representation qualities locally based on distance. Close-range control uses simplified 2D coordinates appropriate for surface interactions, while far-range control uses comprehensive 3D coordinates. This local adaptation ensures optimal data transmission efficiency for each spatial context without compromising necessary accuracy.
3Measurement precision
If distance measurement and coordinate determination functions are added, then control precision is improved, but device functionality complexity increases
Solution Approach 1:
The patent integrates multiple functions into the control device: distance measurement, coordinate determination (both 2D and 3D), and gesture recognition. This multi-functional design resolves the contradiction by consolidating what could be separate complex components into a unified system that adapts its capabilities based on operational context.
Solution Approach 2:
The system performs preliminary distance measurement and determines the appropriate coordinate system before executing control operations. This preliminary action allows the device to prepare the correct data structure and processing mode in advance, improving control precision while managing complexity through structured pre-processing.
