Why is my cat green? Signalling danger to the future. With cats.

Imagine you’re 100 years in the future, exploring a deserted landscape with your trusty cat sidekick. Your cat suddenly turns green. What does it mean?

Pervasive e-receipts: handy or ominous tracking?

When visiting San Jose for the CHI conference last year, I noticed that coffee shops and cafes tend to issue only e-receipts: tap your details into a little screen, and your receipt gets emailed to you. For the traveller who has to submit their expenses, and anyone who’s ever mislaid an Important Paper from a stack of random bits of paper (*cough*), this seems like a great idea. Technology can easily support purchase-tracking, it’s more eco-friendly, stores are more accountable. From the seller point of view, they get the opportunity to get some lightweight user feedback. What’s the problem? Sadly, … More
