Virtual Proximity Sensing - definition
First, let's get to know what a Proximity Sensor actually is!
A proximity sensor is a physical sensor that works using IR (InfraRed) light. In smartphones, it helps to keep the display and touch sensitivity off during an ongoing call to avoid un-intentional touches by the cheek. Whenever the phone is placed on the ear, the IR sensor receives signal and gets activated, then it turns off the display immediately to avoid any circumstances like that.
But in modern smartphones, to execute that particular operation, smartphone manufacturers mostly stopped providing a physical proximity sensor. Instead, they use an advanced algorithm (that's why it is called virtual), and real-time data permutation obtained from existing compulsory gyroscope and accelerometer sensors. The data are processed in such way so that only under several combination the display will turn off and on.
And in current days, most smartphone devices with full touchscreen displays started using this technology rapidly.
Pros: Comparing to the physical proximity sensor, Virtual Proximity Sensing is Power efficient and space saving.
Cons: In a few devices it was observed that the virtual proximity sensing algorithm is not working properly as how it should be. This could happen because of less intelligence or logic in programs used for virtual proximity sensing.
