A new advanced proximity sensor built into the iPhone 4S is not simply a proximity sensor, it’s Siri’s “eyes” to detect whenever you’re close to your iPhone 4S.
If you own an iPhone 4S you will be pleased to know that it has a cutting edge hardware. You might have already noticed a “raise to speak” feature on your iOS 5.
This allows Siri to be activated whenever an active iPhone is raised to the user’s ear or face. It is able to sense the raising action using a proximity sensor capable of detecting how close the user’s face is to the screen.
In a video featured on iFixit.com, it shows how the proximity sensor emits infrared light at all times to support Siri’s ‘Raise to Speak’ feature.
They also demonstrated how the iPhone 4′s proximity sensor is only activated while on a phone call, while the sensor on the iPhone 4S is active whenever the device’s display is on. You can watch the video below.
Well, that’s another reason why the iPhone 4S is light years ahead compared to other smartphones out there. Do you own an iPhone 4S already?
My dad gifted me an iPhone 4S yesterday for my birthday, i wanted to know how SIRI works with the iPhone. This video was very useful for me to know how the SIRI feature works. Thank you so much for the share
