Björn Hartmann: Enlightened Trial and Error

Björn Hartmann (Stanford HCI Group) talks about the different prototyping tools he and his collaborators have built to address two research questions:

1) How can tools enable designers to create prototypes of ubiquitous computing interfaces?

2) How can design tools support the larger process of learning from these prototypes?

(Duration: 1 hour, 13 minutes; this is from Stanford’s HCI Seminar lecture series, February 2009; This is a more in-depth version of the talk Bjorn gave at Interaction 09)
