I have a BSc degree in Artificial Intelligence and studied Medicine for a few years. I am fascinated by the way people think and act and how this can be disturbed or enhanced by technology. It gets really interesting at extremes: expert behaviour, difficult tasks, multitasking, time limits; or non-standard age-groups, disabilities and pathological conditions.

Good design needs beauty and elegance. Good interaction design helps people do what they do best. Good products can be great tools, but have no value if they cannot be used.

Bad design can be very expensive. But bad design also ‘tickles’ when it leads to unexpected, sometimes funny situations. And if no bad design existed, only good design, nobody would see the difference.
