Disney Research's Botanicus Interacticus adds capacitive touch to ordinary plants, we go hands-on
Sure, you spend plenty of time talking to your plants, but have you ever made them sing? In partnership with Berlin-based Studio NAND, Walt Disney's experience development arm, coined Disney Research, has found a way to take human-plant interaction to an almost freakish level. The project's called Botanicus Interacticus, and centers around a custom-built capacitive sensor module, which pipes a very low current through an otherwise ordinary plant, then senses when and where you touch. Assuming your body is grounded, the device uses more than 200 frequencies to determine exactly where you've grabbed hold of a stem. Then, depending on how it may be programed, the sensor can trigger any combination of feedback, ranging from a notification that your child is attempting to climb that massive oak in the yard again, to an interactive melody that varies based on where your hand falls along the plant. Because this is Disney Research, the company would most likely use the new tech in an interactive theme park attraction, though there's currently no plan to do much more than demo Botanicus Interacticus for SIGGRAPH attendees. This week's demonstration is giving the creators an opportunity to gather feedback as they try out their project on the general public. There's four different stations on hand, ranging from a stick of bamboo that offers the full gamut of sensitivity, including the exact location of touch, to an orchid that can sense an electric field disruption even as you approach for contact. While interactive plants may not have a role in everyday life, Botanicus Interacticus is certainly a clever implementation of capacitive touch. You can see it action just past the break.%Gallery-162014%
Fogale Nanotech takes the 'touch' out of 'touchscreen smartphone' at CeBIT
French sensor manufacturer Fogale Nanotech -- historically more of an industrial supplier than a consumer-facing one -- was demonstrating its non-contact capacitive sensors at CeBIT this week and how they might be used for the most consumer-facing application of them all: smartphone interfaces. Fogale had two stations set up, PCs running Windows Phone 7 emulators with the sensors attached out front (oriented like you might place a trackpad on a desk). Though they didn't have any actual phone prototypes on hand with the technology integrated, it's clear that they're trying to drum up support with a manufacturer partner or two; in the meantime, you can get a sense of what's going on by waving your hand over the phone-shaped sensors at the stations. We found that as long as you're within about half inch of the pad, the on-screen cursor flys by in perfect harmony with your finger. Of course, there are plenty of unanswered questions here: deciding on the best user experience for actuating taps is key... but perhaps more importantly, we're not certain that you need your hand waving slightly above your phone while using it anyway. Don't get us wrong, it's super cool -- but are you really that worked up over smudges? Follow the break for a quick video of Fogale's recorded demos plus some time at the live kiosk.
Apple granted patent for handheld that recognizes your hands
You could probably fill a book with Apple patent applications that never amounted to anything, but here's one that's at least been granted -- a "handheld device" that uses capacitive sensors to recognize your identity just by the way you hold it, and subsequently personalize the device's buttons and settings to your hand based on your user profile. That's all that's actually been patented here, but the general idea is a little more grand -- you could theoretically grip a handheld with either hand, and it would automatically generate "button zones" under each finger using sensors (or disappearing buttons, perhaps) baked right into the chassis, making cries of "you're holding it wrong" hopefully fade into obscurity. Still, it's not the first time we've seen Cupertino reaching for digit recognition and we're sure it won't be the last, so we'll just file away our enthusiasm until or unless Jobs announces it on stage.
