As we reported earlier this year, there is no shortage of smartwatches approaching the market. And while some are finally perfecting the fashion style of these clunky screens on our wrists, the functionality remains a challenge. Have you tried swiping a one-inch square screen? Even ballerina fingers can't be elegant or useful on such devices. Unlike other electronics or wearables, the challenges are not about battery life or overheating or speed, but rather that we can't get data in or out of it easily.
But a new way to interact with smartwatches is on the table, coming from researchers in the human-computer interaction labs at Carnegie Mellon University. Their new prototype allows us to physically manipulate the watch's bezel by tilting, clicking and turning it. And apparently this makes it a lot easier to interact with the function of the watch—which is to say that they function as tiny smartphones. This design can work seamlessly with any touchscreen. Their paper outlining the prototype is here [PDF].
There's no substitute for seeing the watch in action, so it's worth reading on and checking out the video below. Navigating a map, for instance, by clicking and tilting makes me honestly wonder why this kind of functionality hadn't been developed yet. Browsing and selecting your music on this prototype is reminiscent of the first time you experienced an iPod. (Well, that might be a bit of a stretch, but this is just a prototype after all.) Gaming ability is also vastly improved with this design, where you can actually imagine playing a simple video shooting game with your watch.
It's made of a 1.5-inch display that sits on an ARM processor, with two Hall-effect displacement sensors that measure the screen's movement. Mechanical sensors are challenging though, as they are more likely to break from dust or water. But the researchers are looking into ways of control that have nothing to do with touching the watch (and it's not voice recognition) but rather interacting with the skin next to the watch. No details on that right now, but expect more true innovation in this area in the near future.
Francois Chambard's screen printing press celebrates printmaking's rich history within the realms of industry and craft
When thinking of mechanical objects, we don't often consider their beauty as much as their basic utility; bulldozers are rarely described as elegant and table saws are prized more for their ability to effectively cut wood than their grace. Despite this underappreciation, there have been a number of designers who

Vai Kai launches first product, a magical play companion 'Avakai'
Nearly two decades ago, Marc Prensky perfectly defined that awkward feeling of explaining how to use an iPad to your grandparents by coining the terms 'digital native' and 'digital immigrant.' Having recently spent a week with my grandparents, I can't help but feel a renewed appreciation for that exact
So far, the robots falling down aren't the ones being given swords
The DARPA Robotics Challenge Finals have been won by a robot named Dr. Chubo. Oh wait a sec, I read that wrong—it's actually called DRC-Hubo. Created by Team KAIST (the Korea Advanced Institute of Science and Technology, something like that country's MIT), the Hubo-bot snagged $2 million in prize money
