Abstract: A method, including receiving, by a computer, a sequence of three-dimensional maps containing at least a hand of a user of the computer, and identifying, in the maps, a device coupled to the computer. The maps are analyzed to detect a gesture performed by the user toward the device, and the device is actuated responsively to the gesture.

Abstract: A method, including receiving, by a computer, a sequence of signals indicating a motion of a hand of a user within a predefined area, and segmenting the area into multiple regions. Responsively to the signals, a region is identified in which the hand is located, and a mapping ration is assigned to the motion of the hand based on a direction of the motion and the region in which the hand is located. Using the assigned mapping ratio, a cursor on a display is presented responsively to the indicated motion of the hand.

Abstract: A method, including receiving, by a computer executing a non-tactile three dimensional (3D) user interface, a set of multiple 3D coordinates representing a gesture by a hand positioned within a field of view of a sensing device coupled to the computer, the gesture including a first motion in a first direction along a selected axis in space, followed by a second motion in a second direction, opposite to the first direction, along the selected axis. Upon detecting completion of the gesture, the non-tactile 3D user interface is transitioned from a first state to a second state.

Abstract: A method including presenting, by a computer, multiple interactive items on a display coupled to the computer, and receiving, from a depth sensor, a sequence of three-dimensional (3D) maps containing at least a hand of a user of the computer. An explicit select gesture performed by the user toward one of the interactive items is detected in the maps, and the one of the interactive items is selected responsively to the explicit select gesture. Subsequent to selecting the one of the interactive items, a TimeClick functionality is actuated for subsequent interactive item selections to be made by the user.

Abstract: A method, including presenting, by a computer system executing a non-tactile three dimensional user interface, a virtual keyboard on a display, the virtual keyboard including multiple virtual keys, and capturing a sequence of depth maps over time of a body part of a human subject. On the display, a cursor is presented at positions indicated by the body part in the captured sequence of depth maps, and one of the multiple virtual keys is selected in response to an interruption of a motion of the presented cursor in proximity to the one of the multiple virtual keys.

Abstract: A method of capturing a digital image with a digital camera includes determining a first exposure level for capturing an image based on a first luminance level of the image, determining a second exposure level for capturing the image based on a threshold exposure level of the image, configuring an exposure level of a sensor of the digital camera based on the second exposure level, capturing the image as a digital image, and adding a non-linear digital gain to the digital image based on a difference between the first exposure level and the second exposure level.

Abstract: A user interface method, including presenting by a computer executing a user interface, multiple interactive items on a display. A first sequence of images is captured indicating a position in space of a hand of a user in proximity to the display, and responsively to the position, one of the interactive items is associated with the hand. After associating the item, a second sequence of images is captured indicating a movement of the hand, and responsively to the movement, a size of the one of the items is changed on the display.

A lens camera may comprise a printed circuit board with a digital image sensor and associated components enclosed in a cylindrical body that may be constructed of metal, plastic, or the like, or combination thereof. Lens cameras may be fitted with lens mounts for attaching host devices, cameras, interchangeable lens, or the like. Lens mounts on a lens camera may be arranged to be compatible with one or more standard lens mounts. Accordingly, a lens camera may be attached to cameras that have compatible lens mounts. Also, interchangeable lens having lens mounts compatible with the lens camera may be attached to the lens camera. Further, lens cameras may communicate with host devices using wired or wireless communication facilities.
