Multi-Sensing Gesture Control for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gesture recognition using a front-facing camera has a low recognition rate and limited control capabilities, allowing only simple actions such as moving left or right, due to the inability to accurately detect gestures made at higher speeds.
Innovation Solution
The implementation of at least two sensing units, such as cameras or distance/light sensing units, which determine a first operating area based on spatial information and generate distinct control instructions based on the configuration relationships between these areas, enabling more complex gesture recognition and control.

Engineering Contradiction Analysis
1Reliability
If a single front-facing camera is used for gesture recognition, then the device structure remains simple, but the recognition rate is low and the device cannot recognize gestures when the operator moves too fast
Solution Approach 1:
The patent divides the sensing function into multiple independent sensing units (first sensing unit and second sensing unit), each capable of detecting gestures in different spatial areas. This segmentation allows the system to track fast movements more reliably by combining data from multiple sources, thereby improving gesture recognition rate without overwhelming complexity
Solution Approach 2:
The patent merges the detection capabilities of multiple sensing units by combining their sensing information through a determination unit. This fusion of data from different spatial areas and angles enables more accurate and reliable gesture recognition, especially for fast movements that a single camera might miss
2Adaptability or versatility
If a single front-facing camera is used, then the device structure is simple, but the control capabilities are limited to simple actions such as moving left or right
Solution Approach 1:
The patent introduces spatial dimensionality by deploying sensing units in different positions (e.g., left and right sides of the device) that detect different spatial areas. This multi-dimensional sensing arrangement enables the system to recognize a broader range of gesture directions and types, significantly expanding control capabilities beyond simple left-right movements
Solution Approach 2:
The patent creates a universal gesture recognition system where multiple sensing units can detect various types of gestures (swiping, tapping, waving, etc.) in multiple directions. The determination unit processes sensing information from different spatial areas to generate diverse control instructions, making the device adaptable to many different control scenarios
3Reliability
If sensing information from multiple spatial areas is processed, then the gesture recognition rate improves, but the processing complexity increases
Solution Approach 1:
The patent introduces a determination unit as an intermediary that receives sensing information from multiple sensing units and processes it to determine the operator's operating area. This intermediary layer simplifies the overall processing complexity by organizing and coordinating the data from multiple sources before generating control instructions
