Gesture Remote Control for Fine Position Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for adjusting the direction and position of devices like moving lights suffer from poor operability, particularly in fine adjustments, requiring repetitive and complex gestures that are not intuitive, especially when distinguishing between fine and rough adjustments.
Innovation Solution
A remote control device equipped with a capacitance sensor that detects time-dependent changes in object position, a motion recognition unit to interpret gestures, and a controller that generates control signals for an apparatus with drivable portions, enabling intuitive fine and rough adjustments through gestures like taps, flicks, and rotations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fine adjustment control is implemented through traditional remote control methods, then the device can be precisely adjusted, but the operation becomes complex and requires repetitive gestures
Solution Approach 1:
The patent replaces traditional mechanical remote control operations with a gesture recognition system using a camera and image processing. Users perform intuitive hand gestures (e.g., sliding hand horizontally/vertically) that are captured by the camera, processed to determine adjustment directions, and transmitted to control the device. This substitution eliminates the need for complex button sequences while maintaining precise adjustment capabilities.
Solution Approach 2:
The patent introduces a gesture recognition system as an intermediary between the user and the device control. The system includes a camera to capture hand gestures, an image processing unit to analyze gesture directions, and a control signal generation unit to translate gestures into device control commands. This intermediary layer transforms simple physical gestures into precise adjustment commands, resolving the contradiction between operational simplicity and adjustment precision.
2Productivity
If multiple adjustment operations are required for large movements, then the device can reach desired positions, but the operation becomes time-consuming and complicated
Solution Approach 1:
The patent replaces multiple sequential button presses with a single continuous gesture. The camera captures the user's hand movement trajectory, and the image processing unit determines both the direction and magnitude of the desired adjustment in one gesture. This allows large movements to be achieved in a single action rather than requiring multiple repeated operations, significantly improving adjustment efficiency and reducing operation time.
3Measurement precision
If different gestures are used for fine and rough adjustments, then precise control is achieved, but the operation becomes less intuitive
Solution Approach 1:
The patent applies local quality by using the same gesture type (hand sliding motion) for both fine and rough adjustments, but varying the gesture characteristics (magnitude and speed of hand movement) to control the adjustment level. The image processing unit analyzes the gesture properties to determine whether to perform fine or rough adjustment, eliminating the need for completely different gesture sets while maintaining control precision and operational intuitiveness.

AI summary
A remote control device includes: a detector that detects a time-dependent change of a position of a recognition target object; a motion recognition unit that recognizes a gesture corresponding to the time-dependent change of the position of the recognition target object detected by the detector; a controller that generates a control signal based on the gesture recognized by the motion recognition unit; and a transmitter that transmits the control signal to an apparatus having a drivable portion to command a movement of the drivable portion.
