Practice English Speaking&Listening with: Venous Materials

Difficulty: 0

Venous Materials is inspired by

vein systems ubiquitous

in nature and in the human body.

By informing us of internal

and external conditions,

Venous Materials can act as a new form

of tangible interaction.

As an example, veins in leaves

transmit pigments that drive color change,

which then informs us of the leafs internal conditions

and also which season it is.

The basic principle of

Venous Materials

is that the liquid is placed

inside a flexible material

to flow through

its internal channels,

when tangible input, like pressing or bending,

is applied by users.

We created and studied  a set of

primitive venous geometries

to act as embedded analog

fluidic sensors

that display flow

and color change.

By integrating different flow

geometries and multicolor fluids

into the analog mechanism,

we can encode dynamic

information into the flow.

Using multilayer compositions

and deformations inputs,

we achieved diverse display utilities,

such as capturing the memory of applied pressure,

and visualizing real time

dynamic motion.

We developed a design tool to provide users

with a simple way to create

and validate their design.

This tool allows for the iterative design of the geometry

and simulation of the flow

according to a specific

mechanical deformation input.

From there, we prototyped with microfluidics technology

that manipulates fluids at the microscale.

We developed fabrication methods along with laser engraving,

accessible tools and materials.

As an Interaction Designer myself, I think Venous Materials

is such an exciting new design opportunity

that the tangible interactive experiences

can be embedded in the flexible and fluidic

mechanical structures.

And this structure itself is the program

that defines the tangible interaction logic.

We envision how Venous Materials

can be integrated with wearables

by using the motion from daily physical activities.

It can also be applied to

embodied interaction and learning,

dynamic Information representation,

and condition indicators for packaging.

Venous Materials form the base architecture

for fluidic mechanisms,

which we believe will carve the path

for future interaction design.
