  1. SIMS 213: User Interface Design & Development Marti Hearst Tues, April 16, 2002

  2. Hardware Small mobile computers Sensor networks Tangible interfaces Software / Systems Ubiquitous computing Context-aware computing Augmented Reality Today: Alternative Interfaces

  3. PDAs are everywhere! • This is new … the first few attempts failed • Gary Trudeau lambasted the failed (ahead-of-its-time) Apple Newton

  4. Bergman & Haitani Reading • What went right with the Pilot? • What can we currently not do well on PDAs? • Peephole: A new idea by Ping Yee

  5. Information Appliances • Main idea: • General purpose computers are too complex • So, create devices that do just one thing well

  6. Ubiquitous Computing • What are the main ideas in Weiser’s 1991 paper? • The disappearance of technology • The opposite of virtual reality • More humanizing, more human interaction • More “natural” interaction, less fiddling • Wireless, interconnected devices • Constant, but unobtrusive, availability • A range of different sizes • Context-aware behavior • Privacy considerations must be addressed – but no solutions proposed • This work really started several years before 1991. After more than a decade, we are no closer to dealing with the privacy issues.

  7. Sensor Networks • Berkeley/Intel sensor motes Slide from lecture by Anind Dey

  8. “Context-Aware” Computing • Related to Ubicomp and Mobile Computing • Takes your current environment into account in making decisions • Turns off cell phone when you enter the lecture hall. • When you ask where to go for a meal, notes that it is morning and you are in Taipei before making a recommendation. • Knows who wrote on the whiteboard so a copy of the ink can be emailed to the author. • Plays music you like when you enter an empty elevator. • Notifies your doctor when your heart rate goes too high.

  9. “Context-Aware” Computing • Makes use of different kinds of information • Geographic • Temporal • Social … ?

  10. Location-Aware Computing • Motivation • location-based action • nearby local printer, doctor • nearby remote phone • directions/maps • location-based information • real • person’s location • history/sales/events • virtual • walkthrough • story of city • augmented • touring machine Slide from lecture by Prasun Dewan

  11. Wearable Pose-Aware Computers • Computers on body • track body relative movements • monitor person • train person Slide from lecture by Prasun Dewan

  12. Alternative Realities • Virtual Reality creates a completely computer-generated environment. • Augmented Reality uses an existing, real-life environment, and adds computer-generated information (virtual objects) thereto. • Diminished Reality filters the environment: it alters real objects, replaces them with virtual ones, or renders them imperceptible. • Mediated Reality combines Augmented and Diminished Reality. • Definitions by Steve “Cyberman” Mann

  13. “Augmented Reality” • Operations based on locations and orientations of users and devices • Cool app: • Point a camera at a sign – see its translation on the screen. Slide from lecture by Prasun Dewan

  14. Tangible Interfaces • Merge physical with computational • Also called Phidgets • Physical Widgets • http://www.cpsc.ucalgary.ca/grouplab/phidgets/gallery/gallery.html • Still only an area of exploration, but lots of fun

  16. ambientROOM Slide from lecture by Jason Hong

  17. Bits represent all symbols extremely flexible quick to disseminate cheap to reproduce computational power Physical direct manipulation persistent collaborative affordances multimodal Tradeoffs of Physical versus Digital • Bits + Physical => Tangibles? • can we get the best of both worlds? • good physical representations of abstractions? Slide from lecture by Jason Hong

  18. Phidgets Slide from lecture by Anind Dey

  19. Why Tangible Interfaces? • Lose something when we use a non-tactile, non-material interface • Tradeoffs between human touch and subtlety of expression vs. search for efficiency • Tangibility / physicality: humans reach for, children experience the world through • Some examples, not all leading to experiences, but meant as inspiration and fodder Slide from lecture by Anind Dey

  20. Summary • Human-computer interaction is heading in many new directions • Which ones will become part of our everyday lives?
