Abstract: An autostereoscopic three-dimensional display system for surgical robotics has an autostereoscopic three-dimensional display configured to receive and display video from a surgical robotics camera, and a first sensor assembly and a second sensor assembly. A processor is configured to detect and track an eye position or a head position of a user relative to the display based on processing output data of the first sensor assembly, and to detect and track a gaze of the user based on processing output data of the second sensor assembly. The processor further is configured to modify or control an operation of the display system based on the detected gaze of the user. A spatial relationship of the display also can be automatically adjusted in relation to the user based on the detected eye or head position of the user to optimize the user's visualization of three-dimensional images on the display.

Abstract: A holographic 3D display system based on virtual array splicing of a spatial light modulator includes a laser configured to generate a coherent light beam, first, second and third beam splitters, first and second reflectors, a shutter array, a spatial filter array, a solid lens, first and second light beam deflection elements and a spatial light modulator. The first and second beam splitters and the first reflector are configured to split the light beam generated by the laser into three parallel light beams to irradiate the shutter array. The shutter array is configured to control the three parallel light beams to sequentially pass therethrough according to a set time sequence. The three parallel light beams passing through the shutter array are expanded and collimated by the spatial filter array and the solid lens to form three parallel light beams with the same size and uniform intensity.

Abstract: A method for interacting with an autostereoscopic display is disclosed. The method includes initiating displaying by the autostereoscopic display a left eye view and a right eye view that contain a virtual manipulated object, determining a real-world coordinate of the virtual manipulated object perceived by a user located at a predetermined viewing position of the auto stereoscopic display, receiving an interactive action of the user's manipulating body acquired by a motion tracker, where the interaction action includes a real-world coordinate of the manipulating body, determining whether an interaction condition is triggered based at least in part on the real-world coordinate of the virtual manipulated object and the real-world coordinate of the manipulating body, and refreshing the left eye view and the right eye view based on the interactive action of the manipulating body acquired by the motion tracker, in response to determining that the interaction condition is triggered.

Abstract: The disclosed head-mounted display assemblies may include a first eyecup and a second eyecup that are configured for positioning in front of intended locations of a user's eyes. The first eyecup and the second eyecup may be movable relative to each other to adjust for an interpupillary distance of the user's eyes. The head-mounted display assemblies may also include a single near-eye display screen configured for displaying an image to the user through the first eyecup and the second eyecup. A flexible shroud may be positioned to provide a seal between a first interior volume of the first eyecup, a second interior volume of the second eyecup, and the single near-eye display screen. Various other methods, devices, systems, and assemblies are also disclosed.
