Textures, for instance, can be modeled as stochastic processes that are modulated by the underlying data. Thus both haptic and sonic textures can be used in an analogous fashion to color in graphical visualization methods. The data forms under consideration include 1D, 2D, and 3D mathematical functions or sampled sensor data that can be rendered using points, lines, surfaces, or vector fields. The final goal of this project is to develop methods that allow blind and visually impaired individuals to explore mathematical functions and data in a multimodal environment. Download it and give it a try.
