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. The user selects a type of force sensation and designs and defines physical characteristics of the selected force sensation using the interface tool. A graphical representation of the characterized force sensation is displayed. The user can include a plurality of force sensations in a compound force sensation, where the compound sensation is graphically displayed to indicate the relative start times and duration of each of the force sensations. The user can also easily adjust the start times and durations of the force sensations using the graphical representation. The force sensations are output to a user manipulandum of a force feedback device to be felt by the user, 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. Sounds can also be graphically represented and synchronized with the designed compound forces.
