A brief overview on TUIs.

1. Tangible Interaction & Interfaces
Marie Schacht | DAI Labor TU Berlin | November 27th 2013
// a brief introduction

2. From the isolation of our workstations
we try to interact with our surrounding
environment, but the two worlds have
little in common. How can we escape
from the computer screen and bring
these worlds together?
[Mackay, Wellner,Gold, 1993]

13.  a vast ocean of digital bits
 a landmass of physical atoms
 Human body
 prisoner of the land
but its visual & auditory senses
• already immersed into the sea
The Iceberg metaphor for TUIs [Ishii, 2008]
 Iceberg: gives physical shape to digital water
 brings digital bits to the surface
 makes them graspable and manipulable for the human hand

15. Visions [MITTangible Media Group]
GUI [1973]
A graphical user interface only
lets us see information and
interact with it indirectly, as if
we were looking through the
surface of the water to
interact with the forms below.

16. Visions [MITTangible Media Group]
TUI [1997]
A tangible user interface is
like an iceberg: there is a
portion of the digital that
emerges beyond the surface
of the water—into the
physical realm—so that we
may interact directly with it.
GUI [1973]

17. TUIs expand the affordances of physical objects,
surfaces, and spaces so they can support direct
engagement with the digital world.
[Ishii, Ullmer 1997]

18. Visions [MITTangible Media Group]
GUI [1973]
Radical Atoms [2012]
Radical Atoms describes
our vision for the future of
interaction, in which all
digital information has
physical manifestation so
that we can interact directly
with it—as if the iceberg
had risen from the depths
to reveal its sunken mass.
TUI [1997]

19.  AR instead of VR
 appreciated dual meaning of “graspable”
 “Tangible Bits”(TUI) instead of “Painted Bits”(GUI)
 physical embodiment of digital information
 but: TUIs are limited by the rigidity of “atoms”
in comparison with the fluidity of “bits”
 limited ability to change the form or properties of physical objects in real time
 can lead to inconsistency with underlying digital models
 seamless -> seamful (2012)
