An interactive object system includes an interactive object and a source of electromagnetic radiation, e.g., an external source. A power harvesting device of the interactive object receives and harvests power from the electromagnetic radiation to power a special effect system of the interactive object. In an embodiment, the interactive object includes a retroreflective material that reflects electromagnetic radiation, which may be of a same or different wavelength as the electromagnetic radiation from which power is harvested. The interactive object system detects the reflected electromagnetic radiation, which may be used to trigger one or more additional actions related to the interactive object.

A virtual and augmented reality system comprising an immersive sound system, sensors, a power source, communications, data processing, and an optical system that delivers photoreceptor density resolution, wide angle, high contrast, binocular vision, continuous depth of field images, is integrated for a fully immersive experience. In one embodiment, an optical system comprises a miniaturized array of projectors geometrically arranged to cover retina photoreceptive areas. Projectors provide full spectrum, amplitude modulated, and controllably divergent beams of light that can be steered with one or more degrees of freedom. Segmented projector arrays greatly improve dynamic performance. An adaptive optics reflector includes an array of fixed, or independently controllable optical elements, that can alter reflected beam properties such that a virtual object may appear to be nearer or further from the viewer. A direct projection, two dimensional array of micro projectors are positioned to deliver a fully immersive image directly into the eye.

The disclosed technology generally relates to displays, and more particularly to projection screens configured to display images with increased brightness and improved contrast and uniformity by using optical layers to control the direction and shape of the return light profiles. The disclosed technology comprises an optical layer configured such that incident light from a light source is directed towards specific positions for all locations on the reflective or transmissive display medium, and a light profile shaping optical layer configured to shape an intensity distribution of light reflected or transmitted from projection screen, prior to displaying the image to a viewer. The direction controlling optical layer and the light profile shaping optical layer may be combined into a single optical medium.

A reflector for a vehicle wheel, or a bicycle wheel, contains an air valve attachment, and a reflective surface affixed to the air valve attachment. The reflective surface contains a portion which is aligned perpendicular to the axis of the air valve attachment. A bicycle wheel and a kit are also described herein.
