First Claim
Patent Images
1. A method for providing directional force feedback in free space to a user, comprising:
- providing a mass rotatable about a movable first axis, the mass and movable axis being responsive to a control signal to generate a force vector having a direction and a magnitude in three dimensional space; and
rotating the mass about at least the first axis to generate the force vector responsive to an application executing in a processing device, the application under control of the user and displaying events to the user, the force vector representing feedback regarding an event in the application.

Abstract
Technology is presented for generating directional force feedback in free space to a user using a mass rotatable about a movable axis. The mass and movable axis are responsive to a control signal to generate a force vector having a direction and a magnitude in three-dimensional space to provide feedback to the user. The force vector is created in response to an event in application executing in a processing device. The force vector represents feedback regarding an event in the application.

9. In a system including a computing environment executing an application communicatively coupled to a directional force feedback device, a method for providing directional force feedback in a device held by a user in free space, comprising:
-
determining a force producing event has occurred in the application ; responsive to a force producing event, determining a force duration based on the force producing event; determining a force vector in three dimensions with respect to an orientation reference position on the device; and generating the force vector for the force duration by rotating a mass in the device, the mass being rotatable about a first axis and a second axis orthogonal to the first axis, the mass rotating to generate the force vector and force duration. - View Dependent Claims (10, 11, 12, 13, 14, 15)
