Although Synaptics never suggested it to us, we don't see any real reason why this new screen can't be used to detect how much finger pressure is being applied (something that would open up a whole host of possibilities).īasically, the ability to detect a whole lot of discrete touch points could, in theory, allow the screen to differentiate between a lightly pressing finger and one jamming the screen (the latter of which would flatten your finger pad and cause it to cover slightly more surface area, which the sensor could pick up on). The new screens also promise lower power consumption and narrower borders around the edges (meaning more of the front of a gadget can be devoted to the screen).Īnd the way we see it, the best is yet to come. And, hey, you can also play multifinger games against friends using two sides of the same screen. The real advantage comes from the new finger-recognition method, which should allow for a greater level of sensitivity and nimbleness with existing multitouch applications-especially those requiring quick presses of multiple virtual "buttons," and anything involving a virtual keyboard. So what can be done with 10 fingers that can't be done with two? Other than a "crumple" gesture that Synaptics is touting as a clever way to "trash" a screen" (check it out in the video below)-not much. The new screen instead acts like a camera sensor and builds an image of all the electrically conductive objects (such as fingertips) within the screen's sensing region at any given moment. The current generation of capacitive touchscreens recognizes points of contact by scanning along the X and Y axes of the screen. The key to this ability is a completely new mechanism for recognizing touch. The new Synaptics ClearPad 3000 Series display, which the supplier announced Wednesday, can detect up to 10 discrete touch points.
