Providing haptic feedback to the handle of a tool
First Claim
Patent Images
1. A tool comprising:
- a handle having a receptacle configured to contact one or more digits of a user'"'"'s hand;
a shaft connecting the handle to a distal end of the tool;
a sensor positioned at a distal end of the tool and configured to measure a property of an object, wherein the sensor comprises a plurality of sensing elements each of which is oriented in a direction that faces away from the shaft with each sensing element facing in a different angular direction; and
a plurality of haptic actuating devices distributed in the receptacle to at least partially surround the one or more digits of a user'"'"'s hand positioned therein, the plurality of haptic actuating devices configured to be actuated based on the measured property to provide haptic feedback to the user,wherein the plurality of haptic actuating devices are arranged in the receptacle in a manner corresponding to a manner in which the plurality of sensing elements are arranged such that each haptic actuating device is matched with a correspondingly located sensing element to be activated based on the sensed property of the correspondingly located sensing element.

Abstract
Tools, such as surgical tools, are normally designed to interact with an object, such as a patient. As disclosed herein, one particular tool is implemented such that it comprises a handle having a feedback portion configured to contact one or more digits of a user'"'"'s hand. The tool also includes a sensor positioned near or in contact with an object. The sensor is configured to measure a property of the object. Also, the tool includes a haptic output mechanism supported by the feedback portion of the handle. The haptic output mechanism is configured to communicate the measured property of the object to the user.

9. A surgical tool comprising:
-
means for sensing a property of a patient at a distal end of the surgical tool; means for imposing a haptic effect on a handle portion of the surgical tool in response to the sensed property, the imposing means configured to impose the haptic effect at a plurality of distributed locations within a receptacle of the handle portion that is configured to accommodate a digit of a user'"'"'s hand, wherein the plurality of distributed locations surround the digit of the user'"'"'s hand when inserted therein. - View Dependent Claims (10, 11)

12. A method comprising:
-
sensing a property with a sensor disposed at a distal end of a tool; determining a direction of orientation of the sensor configured to sense the property; and activating one or more of a plurality of haptic actuating devices positioned in a receptacle of a handle of the tool whereby the one or more of a plurality of haptic actuating devices that are being activated are positioned in the receptacle in a location corresponding to the direction of orientation of the sensor, wherein the one or more of a plurality of haptic actuating devices are activated to impose a haptic effect on one or more digits of a user'"'"'s hand positioned within the receptacle, and wherein the plurality of haptic actuating devices are positioned in the receptacle to surround one or more digits of a user'"'"'s hand positioned therein.
