Build Your Own GX-Controlled Robot?

Did you know that your mobile device has inbuilt sensors that detect motion and orientation?

More interestingly, it is not too hard to read these sensors and use them in your live web pages!

Here we are tapping in to the on-board 3D accelerometer, which obviously detects movement - but also knows which way is UP! Can you explain why?

QR Codes are a great way to share data and information with others, even when no Internet connection is available. Most modern devices either come equipped with QR readers in-built, or freely available.

The default link here is the Geometry Expressions Showcase, but you can use it as an alternative to sending your assessment data via email, web or Google Cloud. You can even use it to send your own messages!
