Abstract

An interface device for interfacing a user with a computer, the computer running an application program and generating a graphical image and a graphical object, comprises a user manipulatable object in communication with the computer, a sensor to detect a manipulation of the object, the sensor providing a signal to the computer to control the graphical image, and an actuator adapted to provide a haptic sensation to the palm of the user in relation to an interaction between the graphical image and the graphical object, the actuator comprising a member that is deformable to provide the haptic sensation. In another version, a mouse for interfacing a user with a computer generating a graphical environment comprising a graphical hand comprises a housing, a position detector to detect a position of the mouse, the position detector capable of providing a first position signal to the computer to control the position of the graphical hand in the graphical environment, and a finger position detector to detect a position of a finger of the user, the finger position detector capable of providing a second position signal to the computer to control a graphical finger on the graphical hand in relation to the position of the finger of the user.

Claims

1. An apparatus, comprising:

a deformable member having a first end, a second end, and an intermediate portion, the intermediate portion of the deformable member having a contact side and a non-contact side; and

a tendon configured to displace the first end of the deformable member relative to the second end in response to a signal, the contact side of the intermediate portion of the deformable member configured to output a haptic sensation, the non-contact side of the intermediate portion being disposed between the contact side of the intermediate portion and the tendon.

2. The apparatus of claim 1, wherein the deformable member is a leaf spring.

3. The apparatus of claim 1, wherein the tendon passes through a guide member fixed to one of the first end and the second end of the deformable member.

4. The apparatus of claim 1, wherein the deformable member is configured to provide a controllable kinesthetic force.

5. The apparatus of claim 1, wherein the deformable member is configured to provide a tactile sensation.

6. An apparatus, comprising:

a deformable member having a first end, a second end, and an intermediate portion, the intermediate portion of the deformable member having a contact side and a non-contact side; and

an elongated flexible member configured to displace the second end of the deformable member relative to the first end of the deformable member in response to a signal, the contact side of the intermediate portion of the deformable member configured to output a haptic sensation, the non-contact side of the intermediate portion being disposed between the contact side of the intermediate portion and the elongated flexible member.

7. The apparatus of claim 6, wherein the elongated flexible member is attached to the second end of the deformable member, the elongated flexible member being configured to apply a force to the second end of the deformable member in a direction towards the intermediate portion of the deformable member.

8. The apparatus of claim 6, wherein at least a portion of the elongated flexible member is disposed within a guide member fixed to one of the first end and the second end of the deformable member.

9. The apparatus of claim 6, wherein the deformable member includes a first portion associated with the first end and a second portion associated with the second end, the first portion being pivotally connected to the second portion.

10. The apparatus of claim 6, further comprising:

an actuator configured to apply a force to the elongated flexible member, the force being configured to cause the elongated flexible member to displace the second end of the deformable member relative to the first end of the deformable member.

11. An apparatus, comprising:

a deformable member having a first end, a second end, and an intermediate portion, the intermediate portion of the deformable member having a first side and a second side;

a contact member attached to the first side of the intermediate portion of the deformable member, the contact member being configured to output a haptic sensation; and

an elongated member attached to the second end of the deformable member, the elongated member being configured to displace the second end of the deformable member relative to the first end of the deformable member, the elongated member being configured to cause the contact member to move in a direction substantially perpendicular to the a direction of the second end of the deformable member when displaced.
