A new nifty piece of code discovered in the iOS 4.3 beta firmware has revealed that the next generation of iPad could come with a proximity sensor. Traditionally, proximity sensors have been employed on touchscreen phones to disable multitouch functions while making a phone call. Not surprisingly, the availability of a proximity sensor on an iPad has caused a number of speculations about possible phone-capabilities.
Apparently, the proximity sensor is going to be provided in iPad 2 for an entirely different reason – case lock. The proximity sensor could possibly help the iPad automatically lock itself when an iPad casing is closed and then unlock when opened.
Some users also speculate that such a feature could be useful in future variants of the iPad that may come without the Home button and Sleep/Wake buttons. That however, is purely speculation at this point.
What do you think of this feature? Do you see other use-case scenarios for a proximity sensor on an iPad? Tell us in the comments.
