Research In Motion filed a patent back in 2006, which describes users tapping a pattern on a device to unlock or lock the device or allow access to a specific application. The patent goes even a step further to describe how the user must tap in a pattern and in a specific rhythm. This works by taking into account the accelerometer data for how hard you tap the screen. This way, others cannot replicate the same way to unlock a device.
It sounds like a seriously good locking mechanism for future devices. So far, we’ve seen Android utilize pattern unlock, and more recently their facial recognition to unlock. It will be interesting to see if and when RIM might use this new technology in BlackBerry devices. Read the full patent here.
