Remote Control Gesture Recognition via Local Motion Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for terminal units require motion data to be transmitted and interpreted by the terminal unit, leading to increased bandwidth and energy consumption, and lack robustness in gesture detection.
Innovation Solution
The remote control autonomously detects and interprets motion sequences to generate simplified control commands, which are then transmitted to the terminal unit, encapsulating motion detection functionality within the remote control and allowing for efficient, low-bandwidth infrared communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If motion data is transmitted from remote control to terminal unit for interpretation, then gesture-based control functionality is achieved, but bandwidth consumption and energy usage increase
Solution Approach 1:
The patent extracts the motion data interpretation function from the terminal unit and relocates it to the remote control device. The remote control's processor autonomously analyzes motion sensor data, identifies gestures, and generates control commands, eliminating the need to transmit raw motion data to the terminal unit for processing.
Solution Approach 2:
The system segments the control functionality by separating motion detection (in remote control) from motion interpretation (in terminal unit). Only essential control commands are transmitted rather than complete motion datasets, reducing communication bandwidth requirements while maintaining full gesture-based control capability.
2Adaptability or versatility
If motion data is transmitted to terminal unit, then gesture interpretation can be performed, but data transmission bandwidth increases
Solution Approach 1:
The patent extracts only the essential control commands from the motion data processing chain and transmits only these compressed commands to the terminal unit, rather than transmitting the entire motion dataset. This dramatically reduces the quantity of data transmitted while preserving full gesture interpretation capability.
Solution Approach 2:
The control system is segmented into motion detection (remote control), motion interpretation (remote control), and command execution (terminal unit). This segmentation allows the remote control to process motion data locally and transmit only the resulting control commands, minimizing bandwidth requirements.
3Adaptability or versatility
If motion detection is performed in terminal unit, then gesture control is achieved, but system complexity increases
Solution Approach 1:
The patent extracts the motion detection and interpretation functionality from the terminal unit and consolidates it in the remote control device. This reduces system complexity by centralizing the computational burden in the handheld device, which already contains processors and sensors for other functions.
Solution Approach 2:
The remote control device is designed with multi-functionality, serving both as a traditional button-based controller and as a motion-sensing gesture controller. By integrating motion sensors, processors, and gesture recognition algorithms into the existing remote control architecture, the system achieves gesture control without adding separate dedicated hardware systems.

AI summary
For the remote control of terminal units of consumer electronics and of computers by means of a remote control with integrated motion sensors, it is suggested to process the detected motion sequences in the remote control itself and interpret them as gestures to the effect that certain gestures correspond to certain commands which are transmitted from the remote control directly to the corresponding terminal unit or to a computer.
