When it comes to unlocking your touchscreen smartphone, there are a few methods to do so, with some opting for the swiping action, while others require you to perform some sort of pattern input before you are able to get to the “fruit”, so to speak. There are also advancements such as Face Unlock in Android 4.0 Ice Cream Sandwich, but I believe that nothing is quicker than using your fingers.
RIM has been seen filing a patent application that might just usher in a new age of unlocking your smartphone – through a pressure sensitive input scheme that will respond according to a user-set pattern of force. Seems to be a radical way of protecting the content on your device, but with the amount of personal information that we carry on our smartphones these days, something like this would make much sense, too.
It would be interesting to see how sensitive the pressure sensitivity on such an unlocking mechanism works, but until it is released in the flesh, we will never no – leaving everything else to nothing but speculation.
