Gesture Control Device 3D Angle Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gesture control systems face difficulties in determining which electronic device among multiple nearby devices should be controlled by a gesture, as they typically only control one device at a time and lack the ability to differentiate between devices in close proximity.
Innovation Solution
A gesture control device that communicates with multiple electronic devices using various wireless and wired methods, employing depth cameras to capture gesture images, establish a 3D coordinate system, calculate vectors and angles, and determine which device is intended for control based on preset angle thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic devices are placed close together to enable flexible control scenarios, then the versatility of gesture control is improved, but the ability to accurately determine which device should be controlled deteriorates
Solution Approach 1:
The patent transitions from 2D gesture recognition to 3D spatial analysis by introducing depth information through Z-coordinate measurement. The gesture control device establishes a three-dimensional coordinate system and uses depth cameras to capture Z-coordinate data, enabling accurate differentiation between multiple devices in close proximity by analyzing the spatial relationship between the gesture and each device in three-dimensional space.
2Device complexity
If traditional gesture control systems control only one electronic device at a time, then the control logic is simple, but the applicability to multiple devices deteriorates
Solution Approach 1:
The gesture control device is designed to simultaneously control multiple electronic devices by establishing spatial relationships with each device. Instead of being limited to single-device control, the system can identify and control any of multiple devices based on the gesture's spatial position, making the control system universal across multiple devices while maintaining relatively simple control logic through angle calculation and threshold comparison.

AI summary
A gesture control system for a device for determining which one of a plurality of devices is to be controlled by a gesture acquires images of a gesture from each of the electronic devices; establishes a three dimensional coordinate system for the gesture image; calculates an angle between a first vector from a start point of the gesture to a center point of each electronic device and a second vector from an end point of the gesture to the center point of each electronic device. Thereby, the electronic device intended as the object to be controlled by the gesture can be determined, according to whether the angle between the first vector and the second vector is less than a preset value. A gesture control method is also provided.
