Synaptics will bring pressure-sensitive screens to Android phones
Right now, the only way to get a pressure-sensitive screen in a smartphone is to snag an iPhone 6s or wait patiently for the Force Touch version of Huawei's Mate S. You won't have to be quite so picky in the near future, though: Synaptics has unveiled ClearForce technology that brings pressure sensitivity to many phones (read: Android). The tech enables the kind of finger-savvy features you've already seen in the iPhone and Mate S, such as contextual menus and photo zooming, as well as extra tricks like scrolling and choosing special keyboard characters. Synaptics isn't saying just which phone makers like the concept, but "leading" brands should launch their ClearForce devices sometime in the first quarter of 2016.
Sony patent claims touch force detection via microphone
In the annals of "clever patents that may never amount to anything," we now have an entry from Sony: a method of sensing touch strength with sound. Since capacitive touchscreens can't detect pressure on their own, a second film is needed that can add weight and cost. Sony's freshly granted patent claims that a microphone can take on that job instead by listening to the sound your finger or stylus makes when it hits the screen and deducing force from that. It could also be used with a camera-based position detection system as shown above, meaning your finger's location and force could be calculated on a non-active surface like an ordinary table. Obviously such a device would only detect taps, not presses, and Sony has claimed a calibration method that the average user may not want to bother with. It probably seemed like a good idea at the time of filing (2009) when other force-sensing options had yet to hit market, but this one seems unlikely to see daylight -- though, you never know.
Sony prototypes pressure-sensitive tactile touchscreen, hopes to use it ASAP
Sony may come up with some far-out ideas, but the company insists this one's a bit closer to home: it's a LCD touchscreen with force sensing resistors and piezoelectric actuators that can detect how much pressure is applied and vibrate the panel respectively. Tech-On was rocking the scene at Open House 2010, and reports that the Cover Flow-like interface shuffled icons faster the harder a demonstrator pressed down, an interesting UI quirk in and of itself. Though the publication sadly didn't get to test out the tactile feedback for themselves, Sony said commercialization might not be too far off -- when asked about that telling Sony Ericsson logo, the company asserted that it'd like to see the tech in mobile phones "as soon as possible." We'd love to hold them to that, but unfortunately the applied pressure mechanic is just a prototype at this point.
Microsoft adds twist to handhelds with force-sensing technology
Surely you're not content with just multi-touch and built-in accelerometers, right? Microsoft Research is expecting not, as it's already working towards integrating force-sensing technology that will enable gestures to twist on-screen imagery without crafting UMPCs out of flexible material. Essentially, the gurus behind the idea feel that implementing said tech would "turn an otherwise passive component that just holds the device together into an active input surface." In the future, it's likely that auditory cues would enable users to know when they've applied enough pressure to cause a change, and of course, they expect it to work hand-in-hand with existing human-computer interfaces. Yeah, who needs keypads these days, anyway? [Warning: PDF read link][Via BBC, thanks Joe]
