Abstract

A force feedback interface and method including an actuator in a non-primary axis or degree of freedom. The force feedback interface device is connected to a host computer that implements a host application program or graphical environment. The interface device includes a user manipulatable object, a sensor for detecting movement of the user object, and an actuator to apply output forces to the user object. The actuator outputs a force sensation on the user object in non-primary axis or degree of freedom. Force sensations such as a jolt, vibration, a constant force, and a texture force can be output on the user object with the actuator. The force sensations can be output in a direction perpendicular to a planar degree of freedom, radial to spherical degree of freedom, and/or along a lengthwise axis of the user object. The system may be utilized where multiple users are able to manipulate respective user manipulatable objects to interact with one another over a network environment and experience the non-primary degree of freedom/axis force sensation.
