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

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

1. Computational coupling of tangible representations to underlying digital information and computation
2. Embodiment of mechanisms for interactive control with tangible representations
3. Perceptual coupling of tangible representations to dynamic intangible representations

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

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 periphery using ambient display media such as light, sound, airflow, and water movement.

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

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
