Now, smart pen that vibrates when you make spelling error

German inventors have developed a new hi-tech pen that gently vibrates every time it senses a spelling mistake or sloppy handwriting.

Lernstift is a regular pen with real ink, but inside is a special motion sensor and a small battery-powered Linux computer with a WiFi chip.

Together those parts allow the pen to recognise specific movements, letter shapes and know a wide assortment of words. If it senses bad letter formation or messy handwriting, it will vibrate, ‘ABC News’ reported.

Users can choose between two functions: Calligraphy Mode – pointing out flaws of form and legibility or Orthography Mode – recognising words and comparing the word to a language database. If the word isn’t recognised it will vibrate, according to Daniel Kaesmacher, the 33-year-old co-founder of Lernstift from Munich.

The other co-founder Falk Wolsky, 36, had the idea for the pen last year while his 10-year-old son was doing his homework.

“His son had been struggling with his work and staying focused and Falk thought there should be a pen that gives him some sort of signal so he stays focused,” Kaesmacher said.

After a year and a half in development, the founders have now brought Lernstift to Kickstarter to begin raising money and gauging interest.



Oculus Rift support for Half Life 2 arrives via Source SDK update

Valve has announced Oculus Rift support via its Source SDK which means you’ll be able to play Half Life 2, Team Fortress 2 and more all using the critically-acclaimed VR headset.

Announced as part of an update to the Source SDK Valve also revealed there would now be support for Mac OS X and Linux users as part of Valves plan to expand past their bread and butter PC market.

For those who like a mod or two with their PC games Steam is also adding Steam Pipe support (their new content delivery system) which should make uploading and then sharing mods much much easier.

Of course the big news is that Valve have now added Oculus Rift support which means that if you have the required mod install a simple piece of code in the command line will turn Half Life 2 into the Virtual Reality experience that you’d always hoped for.

Earlier in the year a video showed Oculus Rift running through Team Fortress enabling gamers to look around the map as they played combining the headset with a conventional controller.
