Ground-based haptic interface comprising at least two decoupled rotary finger actuators
First Claim
1. A ground-based haptic interface, comprising:
- a case having at least two openings and at least two decoupled rotary actuators operatively disposed within the case to extend partially through corresponding openings of the at least two openings in the case for manipulation with fingertips of a single hand,wherein said ground-based haptic interface further includes, for each said rotary actuator;
torque measuring means for measuring torque applied to an axis of rotation of the rotary actuator; and
control means including a motor that enables rotational positioning of said rotary actuator about its axis of rotation as a function of the torque applied and measured by said torque measuring means.

Abstract
A ground-based haptic interface equipped with at least two decoupled rotary finger actuators adapted to be manipulated with the fingertips of a single hand of a user. For each finger actuator, a means are included for measuring the angular position of the actuator or for measuring the torque applied on the axis of rotation of the actuator. Each rotary finger actuator is associated with a control motor adapted to apply, on the axis of rotation of the actuator, a torque that is a function of the angular position of the actuator, or that controls the rotational position of the axis of rotation of the actuator as a function of the torque applied on this axis. The haptic interface can be used as a peripheral of a computer, for example, for interacting with a virtual environment. It can also be applied to the control or manipulation of real objects by being coupled, for example, with a robot or a manipulating arm. The interface also can be telemanipulated.
