Automatic Recording Trigger via Acceleration and Infrared Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current terminal devices require manual activation of the recording function, which can be inconvenient and prone to user error, especially as screen sizes increase and the recording button is often located at the bottom of the screen, making it difficult to access and increasing the likelihood of accidental presses.
Innovation Solution
A method and system utilizing acceleration and infrared sensors to automatically start the recording function by detecting a transition from positive to negative acceleration and the presence of an infrared signal, indicating the user's intention to record, thereby eliminating the need for manual button presses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual button pressing is used to activate recording, then the recording function can be activated, but the operation becomes inconvenient and prone to user error when screen size increases
Solution Approach 1:
The patent replaces the mechanical button-pressing operation with sensor-based detection systems (acceleration sensors and infrared sensors). The acceleration sensor detects motion patterns when the device is brought to the user's mouth, and the infrared sensor detects infrared radiation from the user's face or breath, automatically triggering recording without manual button interaction. This substitution eliminates the need for precise manual operation on large screens while improving reliability through automated detection.
2Area of stationary object
If the recording button is placed at the bottom of the screen to accommodate larger displays, then screen real estate is optimized, but the button becomes difficult to access and increases accidental presses
Solution Approach 1:
The patent extracts the recording activation function from the physical button interface and implements it through sensor detection. By removing the dependency on a physical button location, the system eliminates the trade-off between screen area and button accessibility. The acceleration and infrared sensors can detect user intent regardless of button position, allowing the button to be placed optimally on the screen while maintaining ease of access through automated detection.
3Extent of automation
If automatic sensor-based recording is implemented, then manual operation is eliminated and user error is reduced, but device complexity increases
Solution Approach 1:
The patent leverages the universality of existing smartphone sensors (acceleration sensors and infrared sensors) that are already present in many devices for other functions. By repurposing these existing components for recording activation, the system achieves high automation without proportionally increasing device complexity. The sensors serve multiple functions including screen orientation detection, step counting, and now automatic recording trigger, amortizing the complexity cost across multiple applications.
