Haptic interface including clutch control
First Claim
1. A haptic interface device, comprising:
- means for receiving a first input from a user, the first input producing a corresponding interaction with an environment by the user;
means for determining a maximum level for a haptic sensation in response to the interaction with the environment by the user;
means for receiving a second input from a user, the second input being different from the first input and the second input having a value selected by the user from a set of possible values, the set of possible values comprising a minimum value, a maximum value, and at least one value that is greater than the minimum value and less than the maximum value; and
means for providing the haptic sensation to the user at a level determined by the value of the second input, whereby the maximum level of the haptic sensation is provided to the user if the value of the second input is the maximum value, no haptic sensation is provided to the user if the value of the second input is the minimum value, and the level of the haptic sensation provided to the user is greater than zero but less than the maximum level if the value of the second input is a value that is greater than the minimum value and less than the maximum value.

Abstract
A user can selectively engage some part or all of the haptic display of a haptic interface device to produce an enhanced interaction with an environment with which the user interacts using the haptic interface device. Further, the haptic interface device can be implemented so that the part of the haptic display that is engaged can be engaged to varying degree. The degree of engagement with the haptic display (together with whether part or all of the haptic display is engaged) determines the manner in which the haptic display is experienced by the user. The selective engagement with the haptic display is enabled by adding a haptic clutch model to the underlying haptic model used to produce the haptic display, the haptic clutch model engaging some part or all of the haptic model in response to user input. The addition of a haptic clutch model to the haptic model used to produce a haptic display provides a richer user interaction than is provided by a haptic display produced by the haptic model alone.

1. A haptic interface device, comprising:
-
means for receiving a first input from a user, the first input producing a corresponding interaction with an environment by the user;
means for determining a maximum level for a haptic sensation in response to the interaction with the environment by the user;
means for receiving a second input from a user, the second input being different from the first input and the second input having a value selected by the user from a set of possible values, the set of possible values comprising a minimum value, a maximum value, and at least one value that is greater than the minimum value and less than the maximum value; and
means for providing the haptic sensation to the user at a level determined by the value of the second input, whereby the maximum level of the haptic sensation is provided to the user if the value of the second input is the maximum value, no haptic sensation is provided to the user if the value of the second input is the minimum value, and the level of the haptic sensation provided to the user is greater than zero but less than the maximum level if the value of the second input is a value that is greater than the minimum value and less than the maximum value. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
the means for providing a haptic sensation further comprises means for providing a single degree of freedom, translational haptic output;
the means for receiving a second input from a user further comprises means for providing a single degree of freedom, translational user input; and
the means for receiving a first input from a user further comprises means for providing a single degree of freedom, translational user input.

20. A haptic interface device as in claim 1, wherein:
-
the means for providing a haptic sensation further comprises means for providing a single degree of freedom, translational haptic output;
the means for receiving a second input from a user further comprises means for providing a single degree of freedom, translational user input; and
the means for receiving a first input from a user further comprises means for providing a single degree of freedom, rotational user input.

21. A method for providing a haptic interface to an environment, comprising the steps of:
-
monitoring an environment interaction control apparatus to identify whether a first input has been received from a user, receipt of the first input producing a corresponding interaction with the environment by the user;
monitoring a clutch control apparatus to identify whether a second input has been received from the user, the second input being different from the first input and the second input having a value selected by the user from a set of possible values, the set of possible values comprising a minimum value, a maximum value, and at least one value that is greater than the minimum value and less than the maximum value; and
providing a haptic sensation to the user at a level determined by the value of the second input, whereby a maximum level of haptic sensation is provided to the user if the value of the second input is the maximum value, no haptic sensation is provided to the user if the value of the second input is the minimum value, and the level of the haptic sensation provided to the user is greater than zero but less than the maximum level if the value of the second input is a value that is greater than the minimum value and less than the maximum value.
