Force feedback mechanism for gamepad device
First Claim
1. A method for producing a haptic sensation felt by an operator and corresponding to a condition in an electronic game environment of a specific host device application by developing at least one customized parameter used for producing a reactive haptic force that is applied to the operator through a housing on an input device held by the operator, comprising the steps of:
- (a) responding to a condition in the electronic game environment of a host device by triggering generation of the reactive haptic force by the input device;
(b) determining at least one customized parameter for producing the reactive haptic force that simulates the haptic sensation; and
(c) generating the reactive haptic force along any of a plurality of directional axes by driving at least one mass disposed within the housing of the input device and operatively interconnected to a prime mover wherein the prime mover comprises a gear and an arm attached to the gear, the gear being pivotally mounted to the housing and rotating around a fixed axis, the arm extending outwardly normal to the fixed axis of rotation of the gear, wherein the movable mass is connected to the distal end of the arm such that upon the gear rotating, the movable mass moves through an arc along the plurality of directional axes such that the movement of the mass along the plurality of directional axes causes the reactive haptic force, but the mass is not directly drivingly coupled to any other object, said mass being moved by the prime mover in a manner as defined by said at least one customized parameter, a change in momentum of said at least one mass along at least one directional axis producing the reactive haptic force that is applied to the housing by transmission through the housing to create the haptic sensation felt by the operator holding the housing, corresponding to the condition in the electronic game environment.

Abstract
A hand-held input device provides a directional force feedback that acts on a housing of the device. The input device includes a threaded shaft that is rotatably driven by an electric motor. The motor causes a mass to move in response to a control signal received from a host computing device, such as personal computer that is executing a game or simulation. When the mass is rapidly accelerated or abruptly stopped in response to the control signal, the change in momentum of the mass imparts a directional reactive force to the housing, and an operator holding the housing feels the haptic force.

2. A method for developing at least one customized parameter for a reactive haptic force that simulates an effect in an electronic game comprising a specific host device application, wherein the reactive haptic force is applied to an operator through a housing of an input device held by the operator, comprising the steps of:
-
(a) in response to an effect in an electronic game on a host device, detecting that a first command has been received from a host device, said first command indicating that the effect is required; (b) determining at least one customized parameter for producing at least one reactive haptic force that simulates the effect; and (c) generating each reactive haptic force as defined by said at least one customized parameter, and wherein each reactive haptic force is generated along any of a plurality of directional axes required to simulate the effect by driving at least one mass disposed within the housing of the input device and operatively interconnected to a prime mover wherein the prime mover comprises a gear and an arm attached to the gear, the gear being pivotally mounted to the housing and rotating around a fixed axis, the arm extending outwardly normal to the fixed axis of rotation of the gear, wherein the movable mass is connected to the distal end of the arm such that upon the gear rotating, the movable mass moves through an arc along the plurality of directional axes such that the movement of the mass along the plurality of directional axes causes each reactive haptic force, but the mass is not directly drivingly coupled to any other object, a change in momentum of said at least one mass along at least one directional axis producing the reactive haptic force that is applied to the housing and is thus transmitted through the housing as a haptic sensation felt by an operator holding the housing. - View Dependent Claims (3, 4, 5, 6, 7, 8)

-
(a) a housing adapted to be held by an operator who will experience the reactive haptic force that simulates an effect in the electronic game, where within the housing are disposed a movable mass disposed within said housing and operatively connected to a driver, the movable mass not being directly drivingly coupled to any other object, said driver driving the movable mass, wherein the driver comprises a gear and an arm attached to the gear, the gear being pivotally mounted to the housing and rotating around a fixed axis, the arm extending outwardly normal to the fixed axis of rotation of the gear, wherein the movable mass is connected to the distal end of the arm such that upon the gear rotating, the movable mass moves through an arc along a plurality of directional axes to move in a manner defined by a drive signal applied to the driver, as a function of the at least one customized parameter; (b) a processor adapted to be coupled in communication with a host device; and (c) a memory coupled to the processor, the memory storing machine instructions causing the processor, in response to an effect in an electronic game of a host device, to; (i) detect that a first command has been received from the host device, said first command being applied to the processor to cause the processor to indicate that the effect is required; (ii) in response to the first command being received, determine the at least one customized parameter used to produce the reactive haptic force that simulates the effect; and (iii) generate the reactive haptic force by employing the driver to drive the mass as defined by said at least one customized parameter to produce the reactive haptic force such that the movement of the mass along the plurality of directional axes causes the reactive haptic force, a change in momentum of said mass being created along at least one directional x axis in a plane that is essentially parallel to a bottom of the housing, generating the reactive haptic force that is applied to the housing and is thus transmitted through the housing as a haptic sensation to an operator holding the housing. - View Dependent Claims (10, 11, 12, 13, 14)
