Researcher proposes Thumb on Hand gestures, no touchscreen necessary (video)
Would you be willing to wear an additional device in order to avoid interacting with another? That's the conundrum posed to us by Christian Loclair, a master's student at the Hasso Plattner Institute. His thesis, titled Thumb on Hand Interaction, proposes that users control their mobile equipment with simple hand gestures that are performed independently of their device's touchscreen. This level of freedom requires that users wear a depth camera on their chest, and builds upon prior research from the Hasso Plattner Institute that required use of both hands. Loclair proposes a diverse new set of gestures that users can perform with only one hand, where one's thumb acts as the primary navigation tool and one's palm serves as a trackpad. Another set of gestures is based on the interaction of one's thumb and index finger, which allows users to control sliders and the like. Perhaps once the research team determines how to implement this technology without making our lives more complex, we'll be able to sink our teeth into this one. In the meantime, you'll find a video demonstration after the break.
ZeroTouch 'optical multi-touch force field' makes a touchscreen out of just about anything
The rise of tablets and smartphones has made the touchscreen a rather ubiquitous interface, but they aren't everywhere quite yet. A group of students from Texas A&M intend to change that, however, with the invention of ZeroTouch: a seemingly empty picture frame that lets you turn any surface into an interactive touchscreen. It might not look like much, but ZeroTouch is packing a series of pulsing LEDs and infrared sensors that turn that blank space into a highly sensitive surface. Basically, the strategically placed LEDs cover the open area in a sheet of invisible light. When a hand or stylus enters the picture (or lack there of), those beams are interrupted, providing cues to a piece of software that tracks the object's movement -- and boom! You've got a touchscreen. Of course, this isn't the sort of thing that's going to make it to market anytime soon, but you can check out ZeroTouch rocking the rippling water effect in the video below.
A cinematic tour of fake computer UIs
When your film or TV show takes place in a high-tech landscape, an important part of the mise en scène is the computer interface that your protagonist / supervillain uses to save the planet / initiate the self-destruct sequence. But time and again, that blockbuster GUI is far too high-tech for the film's setting... or just plain silly. According to a recent NPR interview with Hollywood interface designer Mark Coleran, this is no accident: the convention began in the early 1980s, when most people's computer knowledge was limited to coin-op videogames. "The entire point of those things," he says, "is to tell a story... in two seconds, onscreen." Besides, who among us hasn't wanted access to a smiley-faced "virus launch panel" at some point? Hit up the source links for some examples of UIs that have "gone Hollywood," and feel free to drop any of your favorites into the comments.
Multi-robot command center built around Microsoft Surface (video)
While we've given up on ever winning an online match of StarCraft II, that doesn't mean top-down unit control schemes are only for nerds in their mom's basement with their cheap rush tactics and Cheeto fingers and obscene triple digit APMs (we're not bitter or anything). In fact, we kind of like the look of this robot control interface, developed at UMass Lowell by Mark Micire as part of his PhD research. The multitouch UI puts Microsoft Surface to good use, with gestures and contextual commands that make operating an unruly group of robots look easy, and a console-inspired touch control setup for operating a single bot from a first person perspective as well. There are a couple videos after the break, the first is Mike operating an army of virtual robots, using Microsoft Robotics Developer Studio to simulate his soldiers and environment, but the second shows his first person UI guiding a real robot through a maze, in what amounts to a very, very expensive version of that Windows 95 maze screensaver.
Apple applies for 'disappearing button' patent
You know that little sleep indicator light on the front of your new MacBook Pro -- the one that simply disappears when your notebook is wide awake? Apple wants to do that for buttons, too. Cupertino's latest patent application is for pressure-sensitive, capacitive touchscreen materials it could build right into the surface of its aluminum-clad devices, and identify with laser-cut, micro-perforated holes that let light shine from within. According to the filing, the technology could potentially be used to eliminate existing buttons in favor of a smooth, solid slab, and / or integrate new ones into surfaces that weren't previously considered for use. Engineers imagine light-up controls on a laptop's lid that could be used while closed for things like USB charging and media playback, and local heat and sound sensors that selectively light up interface opportunities when users are in close proximity. Not bad, Apple. As long as you let us keep our nice, springy keyboards, we're all for revolutionizing the rest of modern input.
Xcode 3.2 Daily Tip: Adding actions and outlets in IB
More Xcode daily tips for Mac and iPhone developers. Back in the old times, when dinosaurs roamed the earth (and used less sophisticated IDEs), Interface Builder offered a built-in class browser as part of the project window. This browser allowed to you navigate through the Objective-C class hierarchy, and add subclasses along with instance variables and methods. You could generate files from those classes as a skeleton for further development. Then for a while, the class browser went away. And it was missed. But it is back again. New to Xcode 3.2, the Interface Builder Library pane hosts an updated class browser. This new subpane combines features that have recently been in the Class Identity Inspector (namely, adding outlets and actions to a class) with the ability to generate new subclasses from existing classes. So how does it work? I may be a brontosaurus but I prefer the old style browser to the new style "Lineage" display shown here. The new pane is certainly pretty, and it fits in well with the Library pane concept of collecting elements that are universally used throughout a project, but it lacks a certain ease-of-browsing that the old tree-style presentation used to give. All aesthetic and usability concerns aside, it's important to know that the Outlets/Actions interface has moved from its prior home into a new one. The interaction objects remain essentially unchanged. Use the + button to add outlets and actions, the - button to delete them. Double-click the default types to change them to a different class. You can locate a class by entering a string into the search field at the bottom of the pane. The pop-down action menu on the bottom-left offers a number of class-related functions including subclassing, displaying group banners in the class list, writing out updated class files, and more.
