Dynamic Proximity Sensor Control for ARS Keypad Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During Automatic Response System (ARS) services on electronic devices, the proximity sensor often inadvertently turns off the screen when users input numeric characters on a soft keypad, leading to user inconvenience and loss of electric current.
Innovation Solution
Implementing a method that detects specific gestures, such as down-swing and up-swing operations, to disable and enable the proximity sensor accordingly, preventing unwanted screen offs during ARS services by allowing keypad inputs without triggering the screen off function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the proximity sensor is enabled to turn off the screen during calls, then power consumption is reduced and erroneous operations are avoided, but the screen turns off unintentionally when users input on the soft keypad during ARS service
Solution Approach 1:
The proximity sensor's operational state is made dynamic rather than static. The sensor is selectively enabled or disabled based on the detected operation type. During ARS service, when keypad input is detected, the proximity sensor is disabled to prevent unwanted screen off. During regular calls, the proximity sensor remains enabled for its intended function. This dynamic adjustment resolves the contradiction by adapting the sensor's behavior to the current usage context.
2Reliability
If the proximity sensor is always enabled during calls, then screen off function works reliably, but user input on soft keypad is blocked
Solution Approach 1:
The system dynamically adjusts the proximity sensor's enabled state based on operation context. During ARS service, the sensor is disabled to allow reliable keypad input. During regular calls, the sensor is enabled for reliable screen off function. This contextual dynamic adjustment resolves the contradiction between reliability of screen off and ease of keypad input.
Solution Approach 2:
The operation detection mechanism acts as an intermediary between the proximity sensor and the screen off function. It monitors the type of operation being performed and mediates whether the proximity sensor should be active. This intermediary layer allows the system to selectively apply the screen off function based on context, resolving the contradiction between its reliable operation and its interference with keypad input.
3Ease of operation
If the screen remains on during ARS service, then keypad input is enabled, but electric current is unnecessarily consumed
Solution Approach 1:
The proximity sensor's operational state is dynamically adjusted based on service type. During ARS service, it is disabled to keep the screen on and enable keypad input. During regular calls, it is enabled to turn off the screen and save power. This dynamic control resolves the contradiction between enabling keypad input and reducing energy consumption.

AI summary
A method of avoiding screen off during an Automatic Response System (ARS) service is provided. The method includes enabling a proximity sensor in a call connection, detecting one of a first gesture and a second gesture during a call, and upon detecting the first gesture, disabling the proximity sensor.
