    Abstract: A light pattern projector with a pattern mask to spatially modulate an intensity of a wideband illumination source, such as an LED, and a projector lens to reimage the spatially modulated emission onto regions of a scene that is to be captured with an image sensor. The projector lens may comprise a microlens array (MLA) including a first lenslet to reimage the spatially modulated emission onto a first portion of a scene, and a second lenslet to reimage the spatially modulated emission onto a first portion of a scene. The MLA may have a fly's eye architecture with convex curvature over a diameter of the projector lens in addition to the lenslet curvature. The pattern mask may be an amplitude mask comprising a mask pattern of high and low amplitude transmittance regions. In the alternative, the pattern mask may be a phase mask, such as a refractive or diffractive mask.

    Abstract: In embodiments, apparatuses, methods and storage media for human-computer interaction are described. In embodiments, an apparatus may include one or more light sources and a camera. Through capture of images by the camera, the computing device may detect positions of objects of a user, within a three-dimensional (3-D) interaction region within which to track positions of the objects of the user. The apparatus may utilize multiple light sources, which may be disposed at different distances to the display and may illuminate the objects in a direction other than the image capture direction. The apparatus may selectively illuminate individual light sources to facilitate detection of the objects in the direction toward the display. The camera may also capture images in synchronization with the selective illumination. Other embodiments may be described and claimed.

    Abstract: A mechanism is described for facilitating interactive floating virtual representations of images at computing devices according to one embodiment. A method of embodiments, as described herein, includes receiving a request for a virtual representation of an image of a plurality of images, where the virtual representation includes a three-dimensional (3D) virtual representation that is capable of being floated in mid-air. The method may further include selecting the image to be presented via an image source located at a first angle from an imaging plate, and predicting a floating plane to be located at a second angle from the imaging plate, where the image is communicated from the image source to the floating plane via the imaging plate. The method may further include presenting the virtual representation of the image via the floating plane.
