  1. Informal PUIs: No Recognition Required James Landay Jason Hong Scott Klemmer James Lin Mark Newman

  2. WIMPy User Interfaces • Windows, Icons, Menus, Pointer • Hitting limitations of this kind of interface • WIMP designed for limited audience • Full use of eyes • Literate • Full use of hands • WIMP designed for limited situations • Fixed location (often offices) • Sitting down • Single person

  3. Perceptual User Interfaces • PUIs leverage our innate perceptual, motor, and cognitive abilities • Speech recognition, computer vision, sketching, handwriting • Sketching is one part of this bigger push • PUIs more useful for different audiences and wider range of situations • Mobile workers or Home • Speech => Hands-free • Location Tracking => Physical motion

  4. PUIs and Recognition • Key question: • When should perceptual input be recognized? • Immediate recognition can interfere with creativity and communications

  5. Communication and Creativity • Informal visual representation • communicates “unfinished” • encourages creativity • faster to create • higher level comments • Formal visual representation • communicates “finished” • inhibits creativity (detailed) • slower to create • lower-level comments

  6. Informal User Interfaces • Historic bias towards formal user interfaces • Computation over creativity and communication • Structured input to simplify computation • Position: • Recognition interferes with creativity and communication due to errors and perception • Recognition should be minimized or deferred for these kinds of apps

  7. Informal User Interfaces • Sketching • Speech • Handwriting

  8. Informal User Interfaces • Sketching • Speech • Handwriting

  15. Read my important email SUEDE:Informal Prototyping for Speech-based UIs • Supports design practice • example scripts • Wizard of Oz • error simulation • iterative design • Informal user interface • no speech recognition or synthesis • need not be programming expert • fast & fluid design

  21. Takeaway Ideas • Perceptual user interfaces useful for more audiences and more places • Informal User Interfaces valuable for PUIs • Minimize or defer recognition • Creative or communications-oriented tasks • Informal User Interfaces can be applied to a range of perceptual input • Sketching • Speech • Handwriting
