Hasta La Gadget!

Wearable technology is just about to take off, but we can already take a peek at what’s coming after smartwatches and the like. A team of engineers at the University of Illinois at Urbana-Champaign and Northwestern University have made health monitors in the form of stick-on electronic patches.

The development of the patch was led by professors John A. Rogers and Yonggang Huang. Prof. Rogers was already working on electronics that can be applied directly onto human skin like a temporary tattoo, i.e. no patch base needed. But he went ahead with the patch platform because it allows for the use of commercially available – and therefore cheap and abundant – components, as opposed to the tattoo-like electronics that needed custom capacitors, batteries and other parts.

One of the crucial aspect of the engineers’ patch is the origami-like arrangement of the wires connecting the components, which allows for the patch to be bent without damaging the chips.

The engineers believe that stick-on electronics will make it easier to gather patient data. They also think it will lead to more accurate fitness trackers, and even health monitoring devices that can detect clues about the wearer’s condition even before he or she feels sick. Stick a browser to your face and head to the University of Illinois’ News page for more on this amazing invention.

3D modeling software is often used to visualize and develop concepts – anything from a piece of furniture to a video game. Those programs make it easy to transition from idea to prototype and to refine or duplicate sketches, but they require a lot of practice and training to master. A new company called Gravity thinks it can make sketching in 3D almost as easy as doodling with pen and paper.

Gravity uses an infrared pen, a control pad with sensors and a pair of augmented reality glasses. You use the pen to sketch in midair, just above the control pad. You won’t need to be M.C. Escher to start creating 3D models though, because Gravity only allows for sketching in one plane at a time. A switch on the pad lets you switch planes, rotating your virtual object to the side where you want to draw. Your sketch will then be visible to anyone wearing the glasses – it could just be you, or a roomful of people.

The founders of Gravity believe that “CAD [computer-aided design] generates perfect shapes that don’t leave room for the imperfection of your early modeling to allow imagination to keep influencing the idea. CAD requires thinking in terms of functions and variables. This is where imagination is defeated. There is much lost in the process of moving from 2D to 3D.” I’m not sure I buy that. Sure, making complex technology user-friendly can help drive innovation and speed up the development of concepts. On the other hand, professionals need the precision and the shortcuts that CAD and other 3D modeling software provide. For example, will Gravity users be able to cut, copy and paste an exact part of a sketch, and will the commands for those features still be intuitive without being tedious?

Sketching in 3D looks cool, but I’m going to let the pros decide if this is just a high-tech whiteboard or a legitimate alternative to 3D modeling software.

When Valve unveiled its Steam Controller last year, I was quite skeptical about the value of its built-in touchscreen. It turns out many of Valve’s testers had the same opinion. This January, at the 2014 Steam Dev Days conference, the company announced that it was ditching the touchscreen for a more conventional button configuration.

In the video below, you’ll see Valve’s Eric Hope and John McCaskey talk about the evolution of the Steam Controller at Steam Dev Days. At around 23:35 into the video, Eric talks about the point when they realized that the touchscreen was not really that useful. See, Valve added a  “ghost mode” that displayed an onscreen prompt showing you what part of the touchscreen you’re touching as soon as you touch it.

Ghost mode was a great feature. So great that Valve realized it rendered the controller’s screen – which Eric said was the most expensive part of the controller – pointless. Removing the touchscreen also allowed Valve to ditch the built-in rechargeable battery and switch to AA batteries, further driving the cost of the controller down.

Then at around 25:39 in the video Eric discusses why the ABXY corner buttons on the previous prototype also had to be scrapped. Valve labeled the face buttons A, B, X and Y to make them familiar to gamers, only to arrange the buttons in an unfamiliar layout. The result was a jarring experience for testers, who had a particularly hard time accepting the fact that the four ol’ buddies were split into two groups.

As Eric said in the video, the controller is still undergoing internal testing and is nowhere near its final form. They could bring the touchscreen back. They could also place the buttons a bit farther apart. You know what they say about people with big thumbs: they have trouble with cramped controllers.

We’ve featured a couple of PC casemods that incorporated a computer’s hardware into a desk. If Lian-Li pushes through with its prototype, you won’t need to be a modder to have a desk and PC case in one.

The DK01 is basically a tower case with legs. It has all of the features of an enthusiast PC chassis, including LEDs, a transparent glass panel and tool-less mounting. Lian-Li also said that the monitor mount shown in the image above will be included with the desk if it goes into production.

Head to Lian-Li’s blog for more images of the DK01 prototype.
