Dan Norman sui device indossabili (Google Glass). Spetta non solo alle persone utilizzarli intelligentemente, ma soprattutto chi li pensa e realizza deve dargli un design responsabile:
If simultaneous task performance is so deleterious, why do people maintain that they can do it without any deterioration? Well, it is for somewhat the same reason that drunk drivers think they can drive safely: monitoring our own performance is yet another task to do, and it suffers. The impairment in mental skills makes it difficult to notice the impairment. […] It is our responsibility to use technology responsibly. I agree in theory, but not in practice. I’ve often had to unplug my computer from the Internet to complete my work. The providers of these technologies must share the burden of responsible design. Can wearable devices be helpful? Absolutely. But they can also be horrid. It all depends upon whether we use them to focus and augment our activities or to distract. It is up to us, and up to those who create these new wearable wonders to decide which it is to be.
