Lately I've had a few things front of mind. One is early product design concepts, the messy upfront ideation work where you turn opportunities into experiences before anyone's written requirements, something I've long thought of as more upstream than product design.

I'm also thinking about device motion as an input method, using how you physically move a tablet or phone as part of the interaction. And I keep coming back to conversions and "minding the gap" between what people intend to do and what actually happens in a flow. That Expedia example still sticks with me: one optional company field caused so many billing errors that dropping it earned them 12 million more in profit a year.

So: how you get to good ideas early, how devices sense us, and how you close the gap between intent and outcome. Not a bad set of things to chew on.
