Title: Digital Clay: User Interaction Model for Control of a Fluidically Actuated Haptics Device
Author: Askins, Steven A. ; Book, Wayne John
Abstract: Digital Clay is a novel haptics device the purpose which is to form a continuously variable surface that can be used to display shape data or accept shape input. It will be composed of a large number of small fluidic actuators and an array of MEMS micro-valves. Teams are investigating the kinematic architecture, the human interface, the control, the fluidics, and the valve design for this device. This paper describes the development of a computer model to simulate the device as well as human interaction with it via a simulated fmgertip. The model is developed for a conceptual architecture design that could be used in a future prototype wherein the surface is defined by a close-packed array of slender fluidic actuators, however other architectures are also discussed. A key element of controlling this device will be interpreting user input. Therefore the simulations presented attempt to validate algorithms for tracking the user's finger and producing variable height bosses and creases in the surface.
