  1. Beyond Pencil and Paper • Topics for today • Interactive texts • Integrating paper and digital content • What, where, and how do you read? • Interviews with people indicated they tend to discount reading on the computer. • When asked if they read online they said no but ignored email, web news, etc. • Do you think this has this changed? Why?

  2. Interactive Texts • Many forms of interactive text • Hypertext • Chatterbots • Computer-generated texts • Social texts (email, etc.) are for next class so let’s ignore them for now • How do these forms of text change the connection between the author and reader? • What are they good for?

  3. Fluid Texts • Stretchtext • Fine grained hypertext structure • Differs from the web • Novel animated text to maintain reader context • Differs from traditional hypertext where the new lexia replaces (or opens in a separate window) from the prior lexia • Authoring is still a challenge

  4. Fluid Reader

  5. Fluid Reader (2)

  6. Fluid Reader (3)

  7. Fluid Structure

  8. Fluid Writer

  9. Fluid Writer (2)

  10. Character Development in Fluid Texts

  11. Integrating Paper and Digital • We see it all the time • Barcodes • QR codes • TAG codes • Characteristics • Visible • Takes space from other content • No features of the link are human interpretable • May not fit into the aesthetic of linked content

  12. Code-base Invisible Links • We don’t see it all the time • RFID • Data glyphs • Anoto • Characteristics • Rely on special hardware • Not human interpretable • Does not take space • Does not interfere with aesthetic

  13. Paper++

  14. Authoring in Paper++

  15. Links from Content • Can we create links from standard paper content without augmented technology or visible marks? • 1st possibility: Use the text (OCR) • What are the limitations? • 2nd possibility: Treat as a photo • How to index?

  16. The Big Issue • Relying on a camera • Scale, skew, parallax • Scale Invariant Feature Transform • Features that are resilient to different angles • Used for lots of image recognition tasks

  17. Links Using SIFT (or Similar) Features • Links can be from text and image content but • Printed text is not good for distinctive SIFT features • Could combine with lossy OCR • Readers • Do not know where there is a link and where there is not a link • Do not know the boundary of links

  18. Embedded Media Markers (EMMs)

  19. EMM Characteristics • Printed as an layer on top of existing content • Does not take space but can impact aesthetics • Readers know where links are • Readers have some information about results of taking a link • Challenges • Recognition still has problems of SIFT features • Need authoring support for unambiguous EMMs

  20. EMM Authoring Tool

  21. Towards Paper and Digital • Older and Newer technologies • E Ink • Flexible OLED
