Gesture processing

Abstract

Presented is method and system for processing a gesture performed by a user of an input device. The method comprises detecting the gesture and determining a distance of the input device from a predetermined location. A user command is then determined based on the detected gesture and the determined distance.

         16 . A method of processing a gesture performed by a user of an input device, the method comprising:
 detecting the gesture;   determining a distance of the input device from a predetermined location; and   determining a user command based on the detected gesture and the determined distance,   the detected gesture at a first determined distance indicating a first command, and the detected gesture at a second determined distance indicating a second command different than the first command   
     
     
         17 . The method of  claim 16 , wherein detecting the gesture comprises:
 comparing the determined distance with a threshold distance,   the detected gesture at the determined distance less than the threshold distance indicating a first type of interaction, and the detected gesture at the determined distance greater than the threshold distance indicating a second type of interaction.   
     
     
         18 . The method of  claim 17 , wherein the first type of interaction emulates a touch interaction and the second type of interaction emulates a hover interaction. 
     
     
         19 . The method of  claim 17 , wherein the first type of interaction comprises a selection command and the second type of interaction comprises a movement command 
     
     
         20 . The method of  claim 16 , wherein determining the distance of the input device from the predetermined location comprises generating a depth image and processing the depth image in accordance with a depth recognition process. 
     
     
         21 . The method of  claim 16 , wherein determining the distance of the input device from the predetermined location comprises determining the distance of the input device relative to a display. 
     
     
         22 . The method of  claim 16 , wherein determining the distance of the input device from the predetermined location comprises determining the distance of the input device relative to the user's body. 
     
     
         23 . The method of  claim 16 , wherein the input device comprises a body part of the user. 
     
     
         24 . The method of  claim 16 , wherein the input device comprises a device held or operated by the user. 
     
     
         25 . A system for processing a gesture performed by a user of an input device, the system comprising:
 means for detecting the gesture;   means for determining a distance of the input device from a predetermined location; and   means for determining a user command based on the detected gesture and the determined distance,   the detected gesture at a first determined distance indicating a first command, and the detected gesture at a second determined distance indicating a second command different than the first command.   
     
     
         26 . The system of  claim 25 , the detected gesture at the determined distance less than a threshold distance indicating a first type of interaction, and the detected gesture at the determined distance greater than the threshold distance indicating a second type of interaction. 
     
     
         27 . The system of  claim 25 , wherein means for determining the distance of the input device from the predetermined location is to process a depth image in accordance with a depth recognition process. 
     
     
         28 . The system of  claim 25 , wherein means for determining the distance of the input device from the predetermined location is to determine the distance of the input device relative to a display. 
     
     
         29 . The system of  claim 25 , wherein means for determining the distance of the input device from the predetermined location is to determine the distance of the input device relative to the user's body. 
     
     
         30 . A system for processing a gesture performed by a user of an input device, the system comprising:
 an imaging device to produce a depth image of the gesture performed by the user of the input device;   a processor to detect the gesture, determine a distance of the input device from a predetermined location based on the depth image, and determine a user command based on the detected gesture and the determined distance,   wherein a same detected gesture at different determined distances indicates different commands.   
     
     
         31 . The system of  claim 16 , wherein the same detected gesture at a determined distance less than a threshold distance indicates a first type of interaction, and the same detected gesture at a determined distance greater than the threshold distance indicates a second type of interaction. 
     
     
         32 . The system of  claim 16 , wherein the first type of interaction comprises a selection command and the second type of interaction comprises a movement command 
     
     
         33 . The system of  claim 16 , wherein the distance of the input device from the predetermined location comprises a distance of the input device relative to at least one of a display and the user's body. 
     
     
         34 . The system of  claim 16 , wherein the input device comprises at least one of a body part of the user and a device held or operated by the user. 
     
     
         35 . The system of  claim 16 , wherein the imaging device comprises a range camera.
