Organic user interface

In an OUI, the display surface is always the focus of interaction, and may actively or passively change shape upon analog (i.e., as close to non-quantized as possible) inputs.

Early examples of OUIs include Gummi, a rigid prototype of a flexible credit card display,[4] PaperWindows,[2] featuring active projection-mapped pieces of paper, the Microsoft Sphere, one of the first spherical multitouch computers,[3] and DisplayObjects (rigid objects with displays wrapped around them).

It featured a flexible electrophoretic display and an array of 5 bend sensors that allowed for user navigation of content.

[6] The Nokia Kinetic,[7] a flexible smartphone that allows input techniques such as bend, twist and squeeze, and the Samsung Youm,[8] are early commercial prototypes of OUIs.

Although remote gestural interaction violates the principle of Input Equals Output, OUIs generally subsume NUIs.

Also note that OUI is a successor to and form of tangible user interface that always features a bitmapped display skin around its multi-shaped body.

Finally, note that all OUIs are examples of haptic technologies, as their physical shapes, like real objects, provide passive tactile-kinaesthetic feedback even in non-actuated cases.
