摘要： The technology relates to a motion sensory and imaging device capable of acquiring imaging information of the scene and providing at least a near real time pass-through of imaging information to a user. The sensory and imaging device can be used stand-alone or coupled to a wearable or portable device to create a wearable sensory system capable of presenting to the wearer the imaging information augmented with virtualized or created presentations of information.

摘要： During control of a user interface via free-space motions of a hand or other suitable control object, switching between control modes can be facilitated by tracking the control object's movements relative to, and its penetration of, a virtual control construct (such as a virtual surface construct). The position of the virtual control construct can be updated, continuously or from time to time, based on the control object's location.

摘要： Methods and systems for processing input from an image-capture device for gesture-recognition. The method further includes computationally interpreting user gestures in accordance with a first mode of operation; analyzing the path of movement of an object to determine an intent of a user to change modes of operation; and, upon determining an intent of the user to change modes of operation, subsequently interpreting user gestures in accordance with the second mode of operation.

摘要： An AR calibration system for correcting AR headset distortions. A calibration image is provided to an external screen and viewable through a headset reflector, and an inverse of the calibration image is provided to a headset display, reflected off the reflector and observed by a camera of the system while it is simultaneously observing the calibration image on the external screen. One or more cameras are located to represent a user's point of view and aligned to observe the inverse calibration image projected onto the reflector. A distortion mapping transform is created using an algorithm to search through projection positions of the inverse calibration image until the inverse image observed by the camera(s) cancels out an acceptable portion of the calibration image provided to the external screen as observed through the reflector by the camera, and the transform is used by the headset, to compensate for distortions.

摘要： A method is provided, which includes identifying, for presentation, separate interactive objects, each separate interactive object being associated with a particular finger of two or more fingers, wherein a position of each separate interactive object changes in response to a movement of the associated finger of the two or more fingers, obtaining, for at least one separate interactive object, a determination of a property of a screen area surrounding the at least one separate interactive object, and modifying a presentation property of the at least one separate interactive object based on the determined property of the screen area surrounding the at least one separate interactive object. The property of the screen area surrounding the at least one separate interactive object is determined based on at least one of: a brightness, a color and a pattern of the screen area surrounding the at least one separate interactive object.

摘要： The disclosed technology teaches an AR calibration system for compensating for AR headset distortions. A calibration image is provided to an external screen and viewable through a headset reflector, and an inverse of the calibration image is provided to a headset display, reflected off the reflector and observed by a camera of the system while it is simultaneously observing the calibration image on the external screen. The camera is located to represent a user's point of view and aligned to observe the inverse calibration image projected onto the reflector. A distortion mapping transform is created using an algorithm to search through projection positions of the inverse calibration image until the inverse image observed by the camera cancels out an acceptable portion of the calibration image provided to the external screen as observed through the reflector by the camera, and the transform is used by the headset, to compensate for distortions.

摘要： A method and system for controlling an electronic device using gesture and/or a device is provided. The method includes capturing, in a 3D sensor space, an image including a user manipulable hand-held input device and a body part of a user, finding an entry in a database of multiple user manipulable hand-held input devices that matches the image of the user manipulable hand-held input device, wherein each user manipulable hand-held input device, having an entry in the database, respectively generates signals in response to performing one or more specific control manipulations, determining a primary control mode of primarily controlling the electronic device using 3D gestures or using control manipulations directly from the user manipulable hand-held input device, the primary control mode being determined based on a predetermined priority level associated with the user manipulable hand-held input device and controlling the electronic device using the determined primary control mode.

摘要： The technology disclosed relates to distinguishing meaningful gestures from proximate non-meaningful gestures in a three-dimensional (3D) sensory space. In particular, it relates to calculating spatial trajectories of different gestures and determining a dominant gesture based on magnitudes of the spatial trajectories. The technology disclosed also relates to uniformly responding to gestural inputs from a user irrespective of a position of the user. In particular, it relates to automatically adapting a responsiveness scale between gestures in a physical space and resulting responses in a gestural interface by automatically proportioning on-screen responsiveness to scaled movement distances of gestures in the physical space, user spacing with the 3D sensory space, or virtual object density in the gestural interface. The technology disclosed further relates to detecting if a user has intended to interact with a virtual object based on measuring a degree of completion of gestures and creating interface elements in the 3D space.
