Abstract
A method and apparatus for designing force sensations for use with a force feedback interface device. A graphical design interface tool displayed on a host computer receives input from a user to select a type of force sensation and to define physical characteristics of a particular force sensation of that type, such as a spring or periodic sensation. A graphical representation of the characterized force sensation is displayed, providing the user with a visual demonstration of a feel of the force sensation. The user can preferably feel the designed force sensation through a force feedback device connected to the computer, and may iteratively modify and update force sensations to achieve a desired feel. The graphical display can also be modified by the user with a cursor or other input to modify the force sensation.
