20140301603 | SYSTEM AND METHOD FOR COMPUTER VISION CONTROL BASED ON A COMBINED SHAPE - A method and system for computer vision based control of a device are provided in which a shape detection algorithm is applied on an image to identify in the image a finger positioned over or near a user's lips. A device may be controlled based on the detection of the shape, for example, a change of volume of an audio output of the device may be caused. | 10-09-2014 |
20140240225 | METHOD FOR TOUCHLESS CONTROL OF A DEVICE - The invention relates to a system and method for computer vision based control of a device which includes, in one embodiment, obtaining a series of images of a field of view, the field of view including a user's hand; identifying a shape of the user's hand in an image from the series of images; identifying a location within the image of the user's hand in a pre-defined shape; and controlling the device based on an overlap of the location of the hand in the pre-defined and a location of an object in the image. | 08-28-2014 |
20140145941 | COMPUTER VISION GESTURE BASED CONTROL OF A DEVICE - A system and method are provided for controlling a device based on computer vision. Embodiments of the system and method of the invention are based on receiving a sequence of images of a field of view; detecting movement of at least one object in the images; applying a shape recognition algorithm on the at least one moving object; confirming that the object is a user hand by combining information from at least two images of the object; and tracking the object to control the device. | 05-29-2014 |
20140118244 | CONTROL OF A DEVICE BY MOVEMENT PATH OF A HAND - In the invention two consecutive movement paths are detected and displayed content may be manipulated based on the detection of the first movement path of the hand but once a first movement and a second movement path are detected manipulation of the displayed content by the second movement is prevented. Thus, detection of a pair of movement paths prevents unintentional activation of a device. | 05-01-2014 |
20140071042 | COMPUTER VISION BASED CONTROL OF A DEVICE USING MACHINE LEARNING - A method for computer vision based control of a device, the method comprising: obtaining a first frame comprising an image of an object within a field of view; identifying the object as a hand by applying computer vision algorithms; storing image related information of the identified hand; obtaining a second frame comprising an image of an object within a field of view and identifying the object in the second frame as a hand by using the stored information of the identified hand; and controlling the device based on the hand identified in the first and second frames. | 03-13-2014 |
20140053115 | COMPUTER VISION GESTURE BASED CONTROL OF A DEVICE - A system and method are provided for controlling a device based on computer vision. Embodiments of the system and method of the invention are based on receiving a sequence of images of a field of view; detecting movement of at least one object in the images; applying a shape recognition algorithm on the at least one moving object; confirming that the object is a user hand by combining information from at least two images of the object; and tracking the object to control the device. | 02-20-2014 |
20140043234 | COMPUTER VISION GESTURE BASED CONTROL OF A DEVICE - A system and method are provided for controlling a device based on computer vision. Embodiments of the system and method of the invention are based on receiving a sequence of images of a field of view; detecting movement of at least one object in the images; applying a shape recognition algorithm on the at least one moving object; confirming that the object is a user hand by combining information from at least two images of the object; and tracking the object to control the device. | 02-13-2014 |
20130335324 | COMPUTER VISION BASED TWO HAND CONTROL OF CONTENT - A system and method for manipulating displayed content based on computer vision by using a specific hand posture. In one embodiment a mode is enabled in which content can be manipulated in a typically two handed manipulation (such as zoom and rotate). | 12-19-2013 |
20130135199 | SYSTEM AND METHOD FOR USER INTERACTION WITH PROJECTED CONTENT - A system and method for user interaction with projected content are provided. A computer generated image is projected onto a surface, the computer generated image comprising at least one symbol. The projected computer generated image is imaged to obtain a sensor image. The location of the symbol within the sensor image is detected and based on the location of the symbol in the sensor image a device may be controlled. | 05-30-2013 |
