Dynamic CD Gain Adjustment for Mid-Air Gesture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of gesture-controlled devices face difficulties in determining the control display (CD) gain of slider controls, leading to inaccurate adjustments of system parameters, which can result in unintended consequences such as improper machine operation or vehicle control.
Innovation Solution
A method is provided to detect the speed of dynamic dragging gestures and generate auditory or visual feedback to indicate the CD gain, allowing users to adjust slider controls more accurately by varying audio volume, pitch, slider tick spacing, or altering the appearance of the draggable element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a high CD gain is configured for the slider bar to allow for coarse control of the draggable element, then the productivity is improved, but the manufacturing precision deteriorates
Solution Approach 1:
The patent implements dynamic CD gain adjustment based on the detected speed of mid-air gestures. When a user performs a fast gesture, the system automatically increases CD gain for rapid parameter changes; when a slow gesture is detected, the system decreases CD gain for precise control. This dynamic adaptation resolves the contradiction by making the control system flexible rather than fixed, allowing both high productivity and high precision as needed.
Solution Approach 2:
The system changes the CD gain parameter in real-time based on gesture speed detection. By monitoring the velocity of mid-air gestures and adjusting the control-display gain parameter accordingly, the system transitions between coarse and fine control modes, enabling both rapid adjustment and precise control without requiring separate controls for each mode.
2Manufacturing precision
If a low CD gain is configured for the slider bar to allow for fine control of the draggable element, then the manufacturing precision is improved, but the productivity deteriorates
Solution Approach 1:
The system dynamically switches between low and high CD gain based on gesture speed. When users need precise control, they naturally perform slower gestures, triggering low CD gain for fine control. When rapid adjustment is needed, faster gestures trigger high CD gain, eliminating the need to manually switch between precision and speed modes.
Solution Approach 2:
The control system automatically determines the appropriate CD gain level by monitoring gesture speed itself, without requiring user intervention to select control modes. The system serves itself by using the user's natural gesture characteristics to automatically configure the optimal control precision, resolving the contradiction between speed and precision control.
3Productivity
If the CD gain is too high when steering a vehicle using mid-air dragging gesture to control a slider bar, then the productivity is improved, but the reliability deteriorates
Solution Approach 1:
The vehicle control system dynamically adjusts CD gain based on gesture speed detection. Rapid gestures trigger high CD gain for immediate vehicle response, while slower gestures trigger low CD gain for precise control adjustments. This prevents oversteering accidents caused by excessively high fixed gain while maintaining quick response capability when needed.
Solution Approach 2:
The system changes the control-display gain parameter in real-time based on detected gesture characteristics. By monitoring gesture velocity and adjusting the gain parameter accordingly, the system ensures reliable and safe vehicle control operations, adapting the control sensitivity to match the user's intended action speed.
4Manufacturing precision
If the CD gain is too low when quick adjustment of a system parameter is needed, then the manufacturing precision is improved, but the productivity deteriorates
Solution Approach 1:
The system dynamically adapts CD gain to the user's gesture speed. When users need quick parameter adjustment, they naturally perform faster gestures, which automatically trigger high CD gain for rapid system response. When precision is needed, slower gestures trigger low CD gain for fine control, eliminating the need to manually adjust control sensitivity.
Solution Approach 2:
The control system automatically changes the CD gain parameter based on real-time gesture speed detection. This parameter adaptation enables the system to provide both high-speed adjustment and high-precision control as needed, resolving the contradiction between speed and precision in system parameter adjustment.

AI summary
Devices and methods for providing feedback for a control display (CD) gain of a slider control on a gesture-controlled device are described. The method includes detecting a speed of a dynamic dragging gesture, determining the CD gain for the slider control based on the speed, and generating an auditory feedback or a visual feedback for the CD gain. A gesture-controlled device, which carries out the method, may have an image-capturing device, a processor, and a memory coupled to the processor, the memory storing machine-executable instructions for carrying out the method. Advantageously, providing feedback for CD gain of a slider control facilitates accurate adjustment of a system parameter associated with the slider control. The devices and methods may be used in industrial applications, vehicle control among other applications.
