Abstract
A method and apparatus for commanding force effects using suites or categories to allow an application program higher level control over force sensations output by a force feedback interface device. An application program associates a force suite with one or more individual force effects and the suite association is provided to a library available to the application program on the host computer, such as an Application Programming Interface (API). A set of rules is also provided to the library, the rules determining how to apply the force effects in the suite based on a status of the application program. The application program commands at least one force effect in the suite and reports the status of the application program to the library, where the library applies the rules based on the reported status to cause a force sensation based on the commanded force effect to be output by a force feedback interface device coupled to the host computer.
