Wirt makes some interesting predictions about the future of digital music, digital photos, and the trends of high speed networks and increasing storage capacity. He describes a world where almost everything has a built-in hard drive for storing information, but the challenge will be keeping it all in sync.

May 30, 2008 lecture by Hiroshi Ishii for the Stanford University Human Computer Interaction Seminar (CS547). Tangible Bits seeks to realize seamless interfaces between humans, digital information, and the physical environment by giving physical form to digital information, making bits directly manipulable and perceptible. Their goal is to invent new design media for artistic expression as well as for scientific analysis, taking advantage...more

April 18, 2008 lecture by Steve Whittaker for the Stanford University Human Computer Interaction Seminar (CS547). Steve Whittaker reviews the Digital Memories vision, briefly present various studies that challenge that vision, moving on to suggest an alternative approach to the topic that is informed by cognitive science, suggesting that instead of focusing on exhaustive capture we should be designing prosthetic memory devices that are (a...more

November 2, 2007 lecture by Cathy Marshall for the Stanford University Human-Computer Interaction Seminar. Most of us engage in magical thinking when it comes to the long term fate of our digital stuff. At this point, a strategy that hinges on benign neglect and lots of copies seems to be the best we can hope for. Cathy discusses four central themes of personal digital archiving and some additional challenges introduced by home computing e...more

December 7, 2007 lecture by Brian Lee for the Human-Computer Interaction Seminar (CS 547). Today's designers generate content both on paper and online. Designers spread their work over physical and digital media, each of which has powerful, but distinct, sets of affordances. Recent work suggests that augmented paper interfaces can marry the ubiquity of paper interactions with the ease of search, annotation, and presentation afforded by dig...more
