TUI — "tangible user interface" is the driving notion behind Hiroshi Ishii's research group at MIT Media Lab. The design goal of TUI is to make computation physical — something you can touch, smell, taste, hear.

Music Bottles (1999) — information (music) is broken down into multiple channels, and each channel "bottled up". Uncorking a bottle releases its sound.

The shape of an object embues it with meaning. The shape of a tool can change the way we think.

Ishii identifies 3 categories of TUI:

Screens are extremely good at delivering programmable color. Shape and form are more difficult to program — but you can augment physical interactions with projection mapping, sound, haptics, to make objects feel more "charmed" than they really are.

Tangible Cityscape (2013) — a 3d program is made concrete, with physical pixels that actuate on the y-axis.

Where are the smarts? IoT says the smarts are in the thing, but Music Bottles and Dynamicland both take an alternative approach. Some smart centralized brain — a base, camera, or projector — can infuse ordinary objects with magic.

Dynamicland uses dumb objects and a smart projector to make everything a little smart.
