Attention Approximation: from the Web to multi-screen television

Humans are approximate creatures, we aren’t precise, and if this blog is anything to go by, we aren’t concise either! So then why do we persist in pursuing work which is ever more precise using tools which are sold on their precision. Eye-tracking is just one example of this – an individual gaze plot maybe precise, but start to add participants and you get gaze-spaghetti; nothing precise there. So lets step away from precision – in order to get some focus (no pun intended). This idea has led us to think about a new kind of metric we’re calling attention approximation, and our paper at the CHI13 DigitalTV Workshop is it’s first outing.
