Screen fatigue

I read today that ebook sales have fallen for the second or third year in a row. I'm not sure that data is totally correct, but the big growth days in ebooks seem over.  

I love my Kindle. But I still buy physical books, too. And when I have the choice, I prefer not to read on a screen. 

Screens are too present in our lives. The car keyfob has a screen. The odometer is a screen. Your watch has a screen. That wine list the other day came on an iPad (yes, we asked if it has Angry Birds). 

Screens have been the dominant human-computer interface from the beginning. But they're starting to be so ubiquitous that they're being used in ways that are unnecessary. They're a strain on the eyes. They demand focus because they move and they're colourful. 

We are seeing more and more companies trying to change screens or do away with them altogether. I'm hearing rumors that bone induction tech will be big - a quiet voice in your head, when you need it. 

Contextual computing is already here. If we could let it sit in the background while we are living real, human lives, that would be amazing.
