A recent article in a news portal dealt with ground-level traffic lights for smartphone zombies. People who walk around while staring at their smartphones are becoming more and more common – they’re so busy with checking their e-mails or sending messages via messenger services that they entirely forget the environment. Digital whiteboards are now being used in schools instead of traditional blackboards. Learning films dealing with this issue can be viewed on YouTube. And things are changing in the factories too – the maintenance technician no longer has a pad of paper and a toolbox in his hands and is automatically brought to the next “patient” by an autonomously controlled mobile robot while being informed by a tablet how the software of a given system needs to be adapted. Is this the image that comes to mind when we think of daily life, school and industrial production ten or fifteen years ago? Certainly not. The world has changed.
