The term “water-resistant devices” once inferred chunky, niche devices aimed at outdoorsy types. These days, the term “water resistant” and “dust-resistant” are quickly making their way into sleek consumer electronics. Even if you don’t intend to drop your device into a puddle any time soon, peace of mind means that you aren’t gingerly babysitting your device on a rainy day, near a kitchen sink, or next to an accident-prone toddler.

Well engineered water-resistant devices are designed to withstand splashes of water and murky conditions. And devices with new Qualcomm improveTouch technology, a feature of Qualcomm Snapdragon processors, are made to allow you to actually be productive and interact with your touchscreen devices in these same aquatic conditions.

The Sony Xperia Z4 Tablet, touting a 10.1 inch 2K display and powerful Qualcomm Snapdragon 810 processor, is a strikingly thin consumer tablet built to withstand getting wet. So you can take a hot-bubble bath and watch Netflix on the Z4 without fear of dropping it into the suds, or go ahead and let your juice box-bearing child watch their cartoons.

Let’s raise the stakes. Say you’re trying to get some work done on a park bench and the rain starts coming down. The Z4 Tablet, in addition to being water-resistant, is equipped with Qualcomm improveTouch technology, designed to prevent rain drops (or water in general) from interfering with touch inputs by your fingers.

One of the features of improveTouch is called “advanced water rejection,” designed essentially to eliminate false touches from water. Where it really stands out is with multi-finger tracking. It is difficult enough to track a single, wet finger, let alone several. With improveTouch technology and software algorithms developed by Qualcomm Technologies, the screen is engineered to track multiple fingers on a wet screen. Even more impressive is that these features are designed into a svelte and sleek tablet form factor measuring only 6.1mm thick, on top of a 2560x1600 pixel display.

Because this is from Qualcomm Technologies, the touch algorithms take advantage of the Snapdragon 810’s processing power—instead of the traditional way, which relies on an external, underpowered microcontroller. With the technology integrated into the Snapdragon 810 processor, this is just the start of endless possibilities for touch technologies waiting on deck for future mobile devices – powered by Snapdragon.
