We know that iPad sales aren't as great as they used to be, but if there's a grain of truth in a recent patent granted to Apple, then we might witness some nice surprises in the future. PatentlyApple was the first to discover the patent and here are some more details:
If this concept turns out to be true, it could help enable more complex gaming on Apple's iPads and perhaps offer a boost for lagging tablet sale. We use the iPad's front touchscreen for thousands of different tasks, but its back is pretty much useless in terms of interactivity.
Apple could make the back of its iPad tablet much more functional with sensors and controls across its surface. This patent could be used in making the iPad a more complex gaming device, since right now mobile games only involve tapping and swiping. Of course, by using physical controllers, this can change, but a set of new controls on the back of a tablet could indeed transform the iPad into a great gaming device.
The mentioned sensors could be ultrasonic, pressure or capacitive sensors, and the sensed position of a user's hands could either be shown on the front display or not. This definitely looks like a great invention, but judging by Apple's moves, it won't be deployed anytime soon.
