The Foundations of Spatial Computing

  1. 1. The Foundations of Spatial Computing Sjors Timmer @sjors
  2. 2. Now you can create documents with words and pictures Xerox Star 8010 1981
  3. 3. This is not a watered down version of the internet Or a mobile version of the internet It’s just the Internet… On your phone iPhone 2007
  4. 4. It also comes with all the YouTube features you already love YouTube VR 2016
  5. 5. The ‘content’ of any medium is always another medium. Marshall McLuhan The medium is the message
  6. 6. The ‘content’ of any new medium is the previous best selling medium Free after Marshall McLuhan
  7. 7. But it doesn’t have to be that way
  8. 8. Paul Sellers
 How to Make a Mortise and Tenon Joint
  9. 9. What if we could work with information like a carpenter works with wood?
  10. 10. The intelligent use of space Understanding through interaction 1. 2.
  11. 11. 1. The intelligent use of space
  12. 12. The intelligent use of space How we manage the spatial arrangement of items around us, is not an afterthought; it is an integral part of the way we think, plan and behave. - David Kirsh
  13. 13. Extend memory
  14. 14. Sense making
  15. 15. Novel ways of seeing
  16. 16. Experts constantly re-arrange items to make it easy to track the state of the task, or to notice the properties signaling what to do next. - David Kirsh
  17. 17. Simplify choice “Once a context of action has been triggered, the local affordances make clear what can and must be done.” and “prevent us from considering irrelevant alternatives.” David Kirsh
  18. 18. Simplify what’s next “If I can arrange items to display the sequence they are are to be used in, then I don’t have to remember that order. - David Kirsh
  19. 19. Simplify how next The environment also indicates how I should do my next action
  20. 20. Experts create little assembly lines of tasks, switching between short bursts of high cognitive preparation tasks and longer lower cognitive execution tasks.
  21. 21. 2. Understanding through
 interaction
  22. 22. We should invent knowledge work that incorporates the body - Bret Victor The humane representation of thought (2014)
  23. 23. Embodied Interaction is the creation, manipulation, and sharing of meaning through engaged interaction with artefacts. - Paul Dourish
  24. 24. 1. Observable and reportable Interaction with the system should reveal the purposes for which it was designed and how it is intended to be used
  25. 25. 2. Representations should relate to the world The relation between what can be seen and what is represented should make sense within the user’s world experience
  26. 26. 3. Physical representation Being physical humans in a physical world has endowed us with a rich set of skills. We should build upon those
  27. 27. 4. Direct manipulation • Interaction through physical movements • Allow for rapid and reversible actions that provide immediate visible feedback
  28. 28. 5. From space to place Turn space into a place by transforming it from ‘just’ physical to a social environment
  29. 29. 5. From space to place Turn space into a place moving it from ‘just’ physical to a social environment • How you move your body changes how you experience the computing system
  30. 30. 5. From space to place Turn space into a place moving it from ‘just’ physical to a social environment • How you move your body changes how you experience the computing system • The computational system can be adapted through changes in your physical environment
  31. 31. 6. Design for collaboration When the system is centred around manipulating artefacts, than all users can see the results of an action because they all see the same artefact
  32. 32. 7. Design for model making We should design for the dynamic spatial representation of thought - Bret Victor The humane representation of thought (2014) Illustration by David Hellman
  33. 33. Using our body to interact with the world around us frees up underused capabilities for understanding complex information
  34. 34. Recap - We use space to think - We programme our environment through artefacts - Using our body to interact with the world around us opens up underused capabilities to understand complex information - Creating and interacting with dynamic spatial models is the most powerful way to understand complex information
  35. 35. Deep Interaction at UX Brighton - Youtube – Karl Fast The Humane Representation of Thought - Vimeo – Bret Victor More to watch
  36. 36. Thank you! Sjors Timmer @sjors
