iPhone 4S has extra infrared sensor for Siri raise-to-speak
If you have been wondering how Siri reacts so quickly when you "raise to speak", the answer is a tiny infrared LED that's added into the proximity sensor in the iPhone 4S. iFixIt discovered the sensor after a second look, determining that it shines brightly whenever the screen is activated. The light isn't visible to the human eye but it's there. And it's constantly letting Siri know how close your face is to your iPhone 4S.
It does raise a few questions, though. IR is fairly light on battery drain but every little bit extra does add up. Also, iPhone 4 and other older models lack the extra IR sensor, making it seem even more unlikely Apple will ever offer an official port.

Google Search app also has this feature, but it only activates the infrared sensor when you move the phone (it uses the accelerometer to determine this).
Also, you can see that the frequency the infrared is activated is different, probably to reduce battery drain.
Oh wow, I never even knew that was there! That app now has a better spot on my screens. Thanks.

That's not an EXTRA infrared light, that IS the same proximity sensor that also was in the previous models. Now just working all the time (if raise-to-Siri is on) instead of just during calls or in specific apps.
Although on my 4S, raise-to-speak rarely ever works. When I just cover up the sensor, it never activates, so it does seem to use a combination of this and the accelerometer - it only activates together with a movement. But it fails to work many times...
That's exactly what I noticed when I read the post by Allyson—seems like she didn't watch the video very closely. It also completely negates what she says about it being another reason the iPhone 4 may not get Siri (not that I think Siri is coming to the iPhone 4 anytime soon, I don't).
Anyone at TiPb reading this? You need to change the title and content of this post.
id stuff her to the gills for sure. her boobs look nice, Id like to see more!
possible this could be the battery drain huh?
Great for me......!!! nothing to worry about where is it how its gonna respond.....!!!!http://www.1socialmediaagency.com/
Have a look to our blog talking about Iphone 4S Siri-ously One of the most exciting things about the iPhone 4S for ditto’s Tech Lab, is the new Siri assistant. It is truly revolutionary and will change the way in which we use smartphones, mobile devices, and possibly even computers forever. A bold statement, but Siri deserves it... http://www.ditto.tv/blog/2011/11/ditto-is-speaking-siri-ously/
