Abstract
This disclosure provides designer interfaces that present condensed representations of texture functions, the representations displaying selected control points that manipulate the representations, an algorithm that computes a texture function based on the positions of said selected control points, and the texture function generating a signal to control a force on an appendage of a user that touches a tactile surface, and methods of using the designer interfaces.

A method for composing and editing texture functions comprising the steps of:
- providing a designer interface with condensed representations of texture functions on an interface touch screen;
- selecting control points on the interface touch screen that manipulate said representations;
- implementing an algorithm that computes a texture function based on the positions of the control points on the interface touch screen;
- and
- rendering to a tactile surface a force defined by the computed texture function.
A designer interface:
- a graphical user interface that presents condensed representations of texture functions;
- said representations displaying selected control points that manipulate said representations;
- an algorithm that computes a texture function based on the positions of said selected control points;
- and
- said texture function associated with generating a signal to control a force on an appendage that touches a tactile surface.
A method for representing and editing texture comprising the steps of:
- transforming texture into a space-frequency domain,
- providing computational methods for making edits in the space-frequency domain;
- implementing an algorithm to reconstruct the texture from a space-frequency domain representation;
- and
- rendering the reconstructed texture to a tactile surface for exploration and further editing.
