Touch Display Segmentation for Call Input Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch-sensitive displays in user equipment, such as smartphones, face issues with undesired input during calls due to accidental contact, leading to annoying tones and battery consumption, and prior art methods like proximity detectors are costly and unreliable.
Innovation Solution
A method that activates only the end call key button during a call, deactivating the rest of the display to prevent accidental inputs, and reactivates the keypad and volume keys when necessary instructions are required, without relying on expensive sensors or complex signal processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire touch sensitive display is activated during a call, then the user can see and interact with all functions, but accidental contact causes undesired inputs and annoying tones
Solution Approach 1:
The display is segmented into active and inactive regions. During a call, only specific key buttons remain active while the rest of the display is deactivated. This segmentation allows the system to maintain necessary functionality while preventing accidental inputs from affecting inactive areas.
Solution Approach 2:
Different regions of the display have different operational states. The key buttons relevant to call functionality maintain touch sensitivity, while other areas are deactivated. This local differentiation ensures that only intended inputs are registered while preventing accidental contact from causing undesired actions.
2Object-affected harmful factors
If the entire touch sensitive display is deactivated during a call to prevent accidental inputs, then accidental inputs are prevented, but the user cannot see or interact with necessary call functions
Solution Approach 1:
The display functionality is segmented into essential call-related buttons that remain active and non-essential areas that are deactivated. This selective activation ensures that users can still access call functions while preventing accidental inputs from deactivated regions.
Solution Approach 2:
Specific regions corresponding to call functions maintain full operational capability, while other regions are deactivated. This localized quality differentiation ensures that necessary interactions remain possible while preventing harmful accidental inputs.
3Illumination intensity
If the touch sensitive display continuously emits light to remain visible, then the display is always visible for user interaction, but battery power is consumed
Solution Approach 1:
The display illumination is applied periodically rather than continuously. The display activates only when needed for specific interactions and deactivates otherwise, creating a periodic pattern of illumination that reduces overall energy consumption while maintaining visibility when required.
Solution Approach 2:
The display maintains continuous visibility only when it serves a useful purpose. During calls, the display remains visible for call-related interactions but deactivates for other periods, ensuring continuity of useful action while avoiding unnecessary energy consumption during non-essential periods.
