Title: Method and apparatus for designing force sensations in force feedback applications

Abstract: A design interface tool for designing force sensations for use with a host computer and force feedback interface device. A force feedback device is connected to a host computer that displays the interface tool. Input from a user is received in the interface to select a type of force sensation to be commanded by a host computer and output by a force feedback interface device. Input, such as parameters, is then received from the user which designs and defines physical characteristics of the selected force sensation. A graphical representation of the characterized force sensation is displayed on the host computer which provides a visual demonstration of a feel of the characterized force sensation so that the user can view an effect of parameters on said force sensation. The characterized force sensation is output to a user manipulatable object of the force feedback device so that the user can feel the designed force sensation, where the graphical representation is updated in conjunction with the output of the force sensation. The user can iteratively modify force sensation characteristics and feel the results, and store the characterized force sensations.
