Grippable Control Element with Movement Sensor for Gesture Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote controls for multimedia systems are complex and require users to memorize numerous button actions and frequently verify button presses, leading to cumbersome navigation due to the lack of intuitive gestural control in three-dimensional space.
Innovation Solution
A device with a grippable mobile control element and a movement sensor assembly that detects rotation and translation movements relative to a substantially invariant axis, automatically switching between adjustment and gesture recognition modes without the need for button presses, using threshold-based detection and singular-value decomposition to characterize the axis of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote controls are equipped with a large number of buttons to control multimedia system functions, then the system functionality is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent extracts the mode selection functionality from physical buttons and relocates it to automatic detection through movement analysis. The control element automatically determines whether user movements represent adjustment gestures or mode switching gestures, eliminating the need for separate buttons to select between these modes.
Solution Approach 2:
The control element performs self-service by automatically analyzing movement patterns and determining the appropriate mode without user intervention. The system autonomously distinguishes between adjustment gestures and mode switching gestures through threshold-based detection, freeing the user from having to press buttons to select modes.
2Adaptability or versatility
If users press buttons to switch between control modes, then mode switching is achieved, but the ease of operation deteriorates due to increased complexity
Solution Approach 1:
The control element autonomously performs mode switching by analyzing movement patterns. When a gesture exceeds the threshold, the system automatically transitions between adjustment mode and other modes without requiring the user to press any buttons, making the operation simpler and more intuitive.
Solution Approach 2:
The patent replaces the mechanical button-pressing system with an automated detection system based on movement analysis. The threshold-based detection mechanism substitutes for manual mode selection, allowing mode switching to occur automatically in response to specific gesture patterns.
3Measurement precision
If conventional remote controls require frequent verification of button presses, then control precision is maintained, but the productivity and ease of operation deteriorate
Solution Approach 1:
The system provides automatic feedback through threshold-based detection. When a gesture exceeds the predefined threshold, the system automatically recognizes it as a mode-switching gesture and transitions modes accordingly, eliminating the need for users to verify their inputs by watching the screen repeatedly.

AI summary
A device (DISP) for gestural control of a system (SYST) includes a grippable mobile control element (TC), a movement sensor assembly (EC) for measuring movements of the mobile control element (TC), and a processing circuit (DET) for detection the rotation or translation of the mobile control element in relation to an axis that is substantially invariant over a time window. The device (DISP) also includes a circuit (REG) for adjusting the value of at least one parameter of the system, and a circuit (CMD) for controlling activation/deactivation of the adjustment upon a detection by the detection circuit (DET) of a rotation and/or translation of the mobile control element in relation to an axis that is substantially invariant over a time window.
