Robot hand hits 20WPM, nearly ready to embrace infinite monkey theorem
Robot hands have been grabbing, crushing, drawing and otherwise actuating for years, but have you ever seen one properly type? That's the primary purpose of a new Virginia Tech design. Engineers built this Dexterous Anthropomorphic Robotic Typing (DART) hand to mimic the real deal as best they could, down to individually-actuating three-segment digits and 110 degrees of wrist rotation in a package the size of a real human arm. Using a total of 19 servo motors and high tensile strength wire for the tendons, they managed to create a single mechanical paw that can achieve an estimated 20 words per minute while typing. Next, they plan to cover it in silicone skin and add piezoelectric sensors to provide tactile feedback. Imagine that: the next time a secret family member severs your arm with a focused plasma beam, you'll know where to go for replacement.

Microsoft Research reveals RearType, puts QWERTY back where it belongs
We've seen a few wacky split keyboards in our day, and even the occasional back-typing peripheral, but Microsoft Research has just congealed the core ideas into a why-didn't-I-think-of-that device for mobile use. Dubbed RearType, the QWERTY solution literally sticks a three-row keyboard on the back of a tablet PC, allowing users to have the same physical sensation as on laptop or desktop without taking up valuable touchscreen real estate. While there's still a few kinks to be worked out of the system (like how to set it down without triggering input) and no plans yet for commercial availability, a brief study showed users could attain 15WPM speeds on average with a single hour of training, and one participant managed to eke out a healthy 47WPM in the same timeframe. We imagine a certain Motorola device is feeling a mite jealous right about now. See the front of the (non-Microsoft) tablet right after the break, and read the full study at our more coverage link.
A typing tutor for the iPhone
A while back, we reported on a study that (not only had all kinds of holes in it, but) claimed the iPhone's keyboard was two times slower than other phones. But as many commenters said, the keyboard just requires practice.And there's no better way to get it than to jump into a typing tutor. We've seen one before for the iPhone, but reader Travis (thanks!) sent us a tip about TypingWeb.com's free iPhone tutor (just go to their site on your iPhone, and enter some information to create an account), and I was impressed by how smoothly it worked. During the Basic test, I moved pretty quickly-- a nice 36 words per minute. But on the Advanced test, they throw all kinds of things at you (including intentionally misspelled words, so you have to dodge Apple's corrections), and I dropped down to about 16 wpm.Definitely worth a try. A lot of iPhone typing seems to be situation-- moving around in a car or bus, for instance, makes things a lot harder. But at least this will give you a ballpark figure of your typing prowess.
