Reasons to be Cheerful

This is a draft of a column I wrote for ACM interactions magazine. I have been thinking a lot recently about physical and emotional health, and especially about the tricks we play on ourselves to uplift mood and perspective in challenging times.

As interfaces and interactions get more adaptive, the “intelligence” embodied in the data we gather needs to be put to the design of adaptable and socially adept user interfaces as well as carefully filtered content. We need to think about the ‘how’ as well as the ‘what’. More »
