Earphone Head Movement Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current man-machine interfaces lack an efficient method for users to control technical devices using intuitive and flexible head movements, limiting the ability to control devices like audio players and computer cursors without manual input.
Innovation Solution
A control system incorporating an earphone with a sensor device to detect head movement and position information, transmitting this data to a processing unit that recognizes movement patterns and outputs control signals, allowing users to control devices through head gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual input devices (mouse, buttons) are used to control technical devices, then control functionality is achieved, but user interaction efficiency and flexibility are limited
Solution Approach 1:
The patent replaces manual mechanical input devices (mouse, buttons) with a head movement detection system using sensors to detect head position and movement patterns, converting mechanical head movements into control signals for device operation
Solution Approach 2:
The system enables users to control devices using their natural head movements without requiring manual operation of external input devices, making the control system serve itself through the user's innate bodily movements
2Adaptability or versatility
If head movement detection is implemented using sensor devices, then control flexibility and user interaction are enhanced, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into the earphone device, combining audio playback with head movement detection and control signal generation, allowing a single device to perform multiple functions rather than requiring separate components
Solution Approach 2:
The system merges the sensor device, processing unit, and control signal generation into an integrated system where the earphone housing contains both audio components and movement detection components, reducing overall system complexity
3Ease of operation
If head movement patterns are recognized and evaluated, then intuitive control is achieved, but processing complexity and energy consumption increase
Solution Approach 1:
The patent evaluates only specific head movement patterns that correspond to predefined control commands, rather than continuously processing all possible head movements, reducing processing complexity and energy consumption while maintaining intuitive control for recognized patterns
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to control technical devices, such as audio players and computer cursors, using head movements, enhancing user interaction and flexibility by recognizing predefined and learned movement patterns, thereby improving the control experience.
Implementation Method 1
A sensor device which is fixedly secured to the earphone or the headset serves to detect items of movement information and/or position information. The sensor device can have sensors such as for example acceleration sensors
Data Source
AI summary
There is provided a control system (1) comprising an earphone (2) and a processing device (3). The control system (1) has a processing device (3) for the evaluation of head movement information and/or head position information. In that case the processing device is adapted to output at least one control signal dependent on the evaluation, wherein the earphone has a sensor device (9a, 9b, 9c) for detecting the movement information and/or position information and a transmitting device (10) for transmitting the movement information and/or the position information to the processing device.
