A functionality is assigned to each of the one or more physical regions, each of the functionalities corresponding to a tactile input device, and a sequence of three-dimensional (3D) maps is received, the sequence of 3D maps containing at least a hand of a user of the computer, the hand positioned on one of the physical regions. The 3D maps are analyzed to detect a gesture performed by the user, and based on the gesture, an input is simulated for the tactile input device corresponding to the one of the physical regions.

摘要： Mapping apparatus includes a transmitter, which is configured to emit, in alternation, at least two beams comprising pulses of light along respective beam axes that are mutually offset transversely relative to a scan line direction of a raster pattern. A scanner is configured to scan the two or more beams in the raster pattern over a scene. A receiver is configured to receive the light reflected from the scene and to generate an output indicative of a time of flight of the pulses to and from points in the scene. A processor is coupled to process the output of the receiver so as to generate a 3D map of the scene.

摘要： Optical apparatus includes an image sensor and an optical assembly, which is configured to focus optical radiation via an aperture stop onto the image sensor. The optical assembly includes a plurality of optical surfaces, consisting of a first, curved surface through which the optical radiation enters the assembly, a final surface through which the rays exit the assembly toward the image sensor, and at least two intermediate surfaces between the first and final surfaces. An interference filter, which has a center wavelength and a passband no greater than 4% of the center wavelength, and includes a coating formed on one of the optical surfaces. All rays of the optical radiation passing through the aperture stop are incident on the coating over a range of incidence angles with a half-width that is no greater than three fourths of the numerical aperture of the optical assembly.

摘要： A method for mapping includes projecting a pattern onto an object (28) via an astigmatic optical element (38) having different, respective focal lengths in different meridional planes (54, 56) of the element. An image of the pattern on the object is captured and processed so as to derive a three-dimensional (3D) map of the object responsively to the different focal lengths.

摘要： A method for depth mapping includes receiving an image of a pattern of spots that has been projected onto a scene, which includes a feature having a set of elongate appendages, which have respective transverse dimensions that are less than twice an average distance between the spots in the pattern that is projected onto the feature. The image is processed in order to segment and find a three-dimensional (3D) location of the feature. The spots appearing on the feature in the 3D location are connected in order to extract separate, respective contours of the appendages.

摘要： A method for sensing includes connecting an input of a trans-impedance amplifier (TIA) to a first terminal of a sensor, which generates a current in response to an input signal that is incident on the sensor, the signal comprising pulses of a characteristic duration. A resistor is connected in series between a second terminal of the sensor and a power supply, which is set to drive the sensor at a selected voltage. A capacitor is connected to the second terminal in parallel with the sensor and the TIA and in series with the resistor. An upper limit is set on the current that is to be input to the TIA from the sensor, and respective values of the resistor and the capacitor are chosen, responsively to the characteristic duration of the pulses and the selected voltage, to prevent the current input to the TIA from exceeding the upper limit.

摘要： 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.

摘要： A method includes receiving and segmenting a first sequence of three-dimensional (3D) maps over time of at least a part of a body of a user of a computerized system in order to extract 3D coordinates of a first point and a second point of the user, the 3D maps indicating a motion of the second point with respect to a display coupled to the computerized system. A line segment that intersects the first point and the second point is calculated, and a target point is identified where the line segment intersects the display. An interactive item presented on the display in proximity to the target point is engaged.
