  1. Tangible BitsNext Generation HCI Hiroshi Ishii Tangible Media Group MIT Media Laboratory April 23, 2006 CHI 2006 Workshop Montreal, Canada

  2. What drives Design? • Technology Driven Design • begin with an innovative technology, apply it in an application/field • Need Driven Design • identify an existing problem/set of problems, shape process around solving these problems • Concept / Vision Driven Design • define a new concept, design artifacts which embody that concept, and test it

  3. Defy Gravity (= Pixels) GUI TUI • Visual Tactile • General Special Purpose Purpose • Remote Direct and Control Collaborative Manipulation

  4. Abacus: Origin of Tangible Bits Hiroshi ISHII, born 2/4/56 Alisa ISHII, born 9/1/04

  5. Painted Bits (GUI) andTangible Bits (TUI) Graphical User Interface • Intangible representation (pixels on a screen) + • Generic input devices as “remote-controllers” Tangible User Interface • Tangible representation as interactive control mechanism to manipulate the information and computation • Continuity between physical and digital representation in design Xerox Star Urp running on the Sensetable

  6. TUI Key Properties • Computational coupling of tangible representations to underlying digital information and computation • Embodiment of mechanisms for interactive control with tangible representations • Perceptual coupling of tangible representations to dynamic intangible representations

  7. pixels input output sound remote control physical digital intangible representation digital information e.g. building model Input/ output e.g. video projection of digital shadow output control tangible representation physical digital intangible representation digital information Models of GUI and TUI GUI TUI Computational coupling of tangible representations to underlying digital information and computation

  8. TUI Contributions • Double Interactions Loop – immediate tactile feedback • Persistency of tangibles • Coincidence of Input and Output Spaces • Special Purpose vs. General Purpose • Space-Multiplexed Input

  9. 2nd loop through digital computation tangible representation = control 1st loop with immediate tactile feedback intangible representation (video/audio feedback) physical digital sensing display information / computation TUI’s Double Interaction Loops GUI TUI

  10. Seamless transitions of attention between Center and Periphery • to grasp & manipulate bits in the center of user's focus by coupling bits with physical objects and surfaces, and • to be aware of bits at the peripheryusing ambient display media such as light, sound, airflow, and water movement.

  11. Invisible interface?extension of body - good fit • customize • personalize • adapt • co-evolve

  12. Visiblecenter of focus - goal of task • Critical representation of task • Ball has to be always visible in the foreground with a table as reference • You need an interface (paddle) to control the ball

  13. Visual Thinking • Seeing • Drawing • Imagining Robert McKim “Thinking Visually”

  14. Tangible Thinking Mechanical Representation of Knowledge
