Frohe Ostern aus dem Norden. Da an Urlaub dieses Jahr nicht wirklich zu denken ist, ist Kreatives gefragt! 
Wie wäre es mit dem Eiertrullern (geht auch im Garten oder in der Sandkiste )
Auf den Ostfriesischen Inseln – speziell auf Norderney – spielen Einheimische und Touristen das Eiertrullern traditionell in den Dünen. Die Mitwirkenden stellen sich dabei auf die Sandseite und lassen die Eier auf planierten Rampen, einer “Lünskebahn”, hinunterkullern, ohne sie dabei zu werfen. 

Sieger ist derjenige, dessen Ei am weitesten kommt und dabei unbeschädigt bleibt. Als Gewinn erhält er das Ei des Gegners. Aus Naturschutzgründen findet das Eiertrullern heutzutage nur noch auf künstlich aufgeschütteten Sanddünen am Strand statt.

English – “Happy Easter from the north. Since vacation this year is not really an option, some creativity is required!

How about the –Eiertrullern– (also works in the garden or in the sandpit)
On the East Frisian Islands – especially on Norderney – locals and tourists traditionally play the –Eiertrullern– in the dunes. The participants stand on the sand side and let the eggs roll down on leveled ramps, a “Lünskebahn”, without throwing them.

The winner is the one whose egg gets the furthest and remains undamaged. As a win he receives the opponent’s egg. For nature conservation reasons, egg trolling now only takes place on artificially raised sand dunes on the beach.”

Ein paar schöne erholsame Tage im Kreis der Familie.

Tracking your body in VR

A new passion!

VR is a new passion of mine, that I play with in my freetime, but also explore as a developer and tech enthusiast.

As video quality has evolved a lot in the past 2 years, the big topic now is full body immersion.

What needs to be tracked in VR?

The following things are becoming more important:

  • Hand-Tracking: hand & fingers, touch, grab & place …
  • Eye-Tracking: left & right eye, focus …
  • Lip-Tracking: speech, facial expressions
  • Body-Tracking: arms, legs, hips …
  • Free Locomotion without boundaries
  • Smell & Taste-Tracking
  • Brain & Neural Tracking

I will use this article to collect things that are already available, diy projects, experiments and things that are in their early stages.

Hand Tracking

Hand & finger tracking is already making its way into consumer products. It is still not widely integrated, but has made big jumps the past year.

Eye Tracking

Eye tracking is not only important to make avatars more life-like, but also to track your eye focus and help to reduce processor load.

Lip Tracking

Lip tracking has made a big jump, with the new Vive Lip tracker and is important for social interactions.

Body Tracking

Body tracking is one of the areas, that has so many projects attached to it. There are so many neat solutions out there, that almost anyone can use it by now.

  • KinectToVR – Full-Body Tracking with your Kinect for Xbox 360, Kinect for Xbox One or PlayStation Move + Eye

Free Locomotion Tracking

Free locomotion is one of the biggest challenges in VR right now. You can increase your playarea, but that is still limiting and requires space. Their are VR treadmills, but none of them really reproduces life-like natural movement yet. And those solutions that come close, are still out of your reach. Most of the tracking above is somehow covered and will be available soon, while real locomotion is really the hardest to solve of them all.

  • Natural Locomotion – Natural Locomotion is an application that emulates the controller thumbstick input (to use in any game), to walk, run and jump more naturally moving your arms or your feet. It includes a driver for SteamVR for this purpose.

Tools & Software

  • VirtualHere – allows USB devices to be used remotely over a network just as if they were locally connected!

Always crucial to have the right look for yourself in VR :)

Merry Christmas

Time to slow down and enjoy some time with family & friends.


I heard the bells on Christmas Day
Their old, familiar carols play,
And wild and sweet
The words repeat
Of peace on earth, good-will to men!

“Christmas Bells” by Henry Wadsworth Longfellow

All the best wishes.

ZombieLoad Attack

“After Meltdown, Spectre, and Foreshadow, we discovered more critical vulnerabilities in modern processors. The ZombieLoad attack allows stealing sensitive data and keys while the computer accesses them. While programs normally only see their own data, a malicious program can exploit the fill buffers to get hold of secrets currently processed by other running programs. These secrets can be user-level secrets, such as browser history, website content, user keys, and passwords, or system-level secrets, such as disk encryption keys.” – zombieloadattack.com

There seems to be a new security related story every day. Read about the latest CPU related issues at CPU.fail.

Chrome 56 .. whats new?

With Chrome 56, web apps can now communicate with nearby Bluetooth Low Energy devices using the Web Bluetooth API, position sticky is back – making it easy to create elements that scroll normally until sticking to the top of the viewport. And HTML5 by Default is enabled for all users.

Chrome 56 on iOS also adds the ability to scan QR codes directly within Chrome. So many thought QR-Codes were dead, well not so much !

“The DxO ONE plugs directly into your iPhone with a simple click. Once it is connected, the iPhone’s Retina display immediately transforms into the camera’s viewfinder, allowing you to compose the image and adjust every setting.”

Really love the concept, even though I am an Android phone user through and through :)

Epichrome is made up of two parts: an AppleScript-based Mac application (Epichrome.app) and a companion Chrome extension (Epichrome Helper). Epichrome.app creates Chrome-based site-specific browsers (SSBs) for Mac OSX (Chrome must be installed in order to run them, but they are full Mac apps, each with its own separate Chrome profile).”
