V [m3] V [m ] h s 3 1 1 2 3 Background Constructal Theory • The hierarchic structures (tree networks) that we observe in natural and artificial systems are the “fingerprint” of the minimization of flow resistance between a finite volume and one point. • An access problem can be solved through the optimization of the shape of the smallest, inner-most space elements and the hierarchic assembly of these elements into larger “constructs” until covering the entire geometric space. • The abstraction of a space of customization as a geometric space in need of access optimization, allows a designer to effectively develop a product architecture for customized products.

Specifically, the device will enable: • Shape input through a “sculpting” interaction mode • Shape display of a computer model (e.g. CAD model) • Stiffness (“feel”) display of shapes with various material properties. Demonstrate the digital clay device on a variety of mechanical and architectural shape design applications, distributed collaboration, and dynamic simulations. Background Hydraulics will be used for actuation and sensing. A formable skin will comprises the bulk and shape of the “clay” device. The skin will have inflatable bladders to enable the skin to change shape and to sense user forces. Stereolithography used to fabricate skin and clay structure. MEMS technologies will be utilized to fabricate array of pressure sensors and valves in device backplane. Human-computer interface studies will determine appropriate methods of interaction with clay devices. Contributions & Benefits Define state-of-the-art in haptics (force-based) computer interaction.
