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)

When faces become hyperlinks

The algorithms for facial recognition have improved a lot in recent years. Here is a company showing a working prototype of a mobile app that recognizes faces and attaches links to social network layers to them:

The prototype was shown last year — but there was a live demo at the Mobile World Congress in Barcelone last week. Obviously the company that also created the service wants to turn this in to a real application.

The implications of this is shown in the video: when looked through the “eyes of the app” people virtually carry logos, brands, name tags and messages around.

10/GUI & con10uum

10/GUI (by Clayton Miller) is an novel approach to human-computer interaction. But it draws attention to the fine line designers will need to walk to effectively create physical human-computer interactions.

The video demonstrates the potential advantages of navigating within a desktop interface with up to ten fingers, rather than via a single cursor:
