Electronic Device Thumb Finger Operation Screen Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, such as smartphones, face limitations in controlling display functions post-authentication, particularly in distinguishing between thumb and finger operations for canceling limitations, which affects user convenience and interface switching.
Innovation Solution
An electronic device with a controller that detects operations to cancel limitations and presents different screens based on whether the operation is performed with a thumb or a finger, using a fingerprint/thumbprint sensor to authenticate and determine the type of operation, thereby simplifying the user interface switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the device presents a single default screen after canceling operation limitation, then the control logic is simple, but user convenience deteriorates because it cannot adapt to different operation scenarios (one-hand vs two-hand use)
Solution Approach 1:
The system performs preliminary detection of the operation type (thumb vs finger) before presenting the screen, using the fingerprint sensor to identify whether a thumb or finger is used. This preliminary action allows the system to prepare and present the appropriate screen (first screen for two-hand operation, second screen for one-hand operation) in advance, improving user convenience without requiring complex real-time adjustments
2Ease of operation
If the device uses fingerprint sensor to detect operation type, then user convenience is improved through automatic interface switching, but device complexity increases due to additional sensor integration and detection logic
Solution Approach 1:
The fingerprint sensor is designed to serve multiple functions: it not only performs user authentication but also detects the type of operation (thumb vs finger) to determine which interface to present. By making the sensor multi-functional, the system achieves automatic interface switching without adding separate detection hardware, thereby improving user convenience while minimizing the increase in device complexity
3Adaptability or versatility
If the device presents different screens based on operation type, then adaptability is improved for different usage scenarios, but measurement precision requirements increase for distinguishing thumb from finger operations
Solution Approach 1:
The system uses feedback from the fingerprint sensor to continuously refine its detection of operation type. By analyzing the characteristics of the fingerprint data (such as pressure distribution, contact area, or sensor activation pattern), the system can accurately distinguish between thumb and finger operations. This feedback mechanism ensures high measurement precision for operation type detection, enabling the device to adapt to different usage scenarios reliably

AI summary
An electronic device includes a display, and at least one controller that, when an operation to cancel limitation of operations of the electronic device is detected, is configured to cancel the limitation of operations and presents a first screen on the display. The at least one controller is further configured to present a second screen which is different from the first screen on the display when the operation to cancel the limitation of operations is an operation with a thumb.
