Gesture-Controlled Communication System Using Sensor Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems lack the ability to control communication sessions based solely on user gestures without the need for a communication terminal, especially in environments with widespread image sensors, microphones, and speakers.
Innovation Solution
A communication system that utilizes processing circuitry to recognize user gestures detected by sensors, such as cameras and microphones, to initiate electronic communication sessions with designated destinations, allowing for control of communication start, end, and type through gesture recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If communication control is performed using buttons, switches, or touch panels on a mobile terminal apparatus, then the operation is reliable and recognizable, but the ease of operation is reduced due to requiring physical manipulation
Solution Approach 1:
The patent replaces mechanical input devices (buttons, switches, touch panels) with gesture recognition based on sensor data. The mobile terminal apparatus uses acceleration sensors and other sensors to detect user gestures in space, converting physical movements into control commands. This substitution eliminates the need for direct contact with mechanical interfaces while maintaining reliable control through recognizable gesture patterns.
Solution Approach 2:
The patent introduces gesture recognition technology as an intermediary between user intent and system control. Instead of direct button pressing, the system captures sensor data, processes it through gesture recognition algorithms, and translates recognized gestures into control commands. This intermediary layer enables more natural interaction while preserving system reliability through structured interpretation of gestures.
2Ease of operation
If gesture recognition is implemented using sensor data, then the ease of operation is improved, but the difficulty of detecting and measuring increases due to complex gesture analysis
Solution Approach 1:
The patent segments the gesture recognition process into distinct modules: sensor data acquisition, preliminary signal processing, feature extraction, gesture pattern matching, and control command generation. By dividing the complex detection task into smaller manageable segments, the system reduces the overall difficulty of gesture detection while maintaining high ease of operation.
Solution Approach 2:
The patent performs preliminary processing of sensor data including filtering, noise reduction, and feature extraction before gesture recognition. Common gesture patterns are pre-defined and stored in the system, allowing for faster and more accurate matching during actual operation. This preliminary preparation reduces the computational complexity during real-time gesture detection.

AI summary
A communication system includes processing circuitry that responds to a recognition result by initiating an electronic communication session with a user-designated destination. The recognition result corresponds with a recognized gesture made by the user as detected by a sensor, and the user-designated destination corresponds with the recognized gesture. A method and non-transitory computer program product also respond to the recognition result in a similar manner.
