In one implementation, a method includes detecting, using a processor, user input through a camera lens. The method further includes determining, using the processor, that an identity of a user, selected from identities of at least two users, is associated with the user input. The method also includes tracking, using the processor, a local interaction between the at least two users based on at least the identity, the user input, and stored rules that govern the local interaction. The tracking can include determining whether the user has complied with the stored rules that govern the local interaction. Furthermore, the local interaction can include a multiplayer game.

In one implementation, the present disclosure provides a method for imparting motion to a magnetically movable object. The method includes disposing the magnetically movable object over a display of an electronic device. The method further includes imparting motion to the magnetically movable object by adjusting a magnetic field that is produced by a magnetic field source, the magnetic field being applied to the magnetically movable object through the display of the electronic device. The adjusting the magnetic field can be based on a location of the magnetically movable object over the display. Furthermore, the display can be a touch sensitive display and the adjusting the magnetic field can be based on touch input of the touch sensitive display. The imparting motion can include moving the magnetically movable object around the display.

Methods and techniques to implement a digital signal processor for avoidance of audio feedback are disclosed, in particular, audio signal processing systems that reduce the requirement for physical segregation of sound acquisition and diffusion zones. In a more general aspect, the components and techniques described herein provide a for a sound space and sound processing equipment such that sound travelling electronically in a loop through the sound processing equipment that is output into a physical sound diffusion zone, received at the input to the sound processing equipment, and then re-amplified, etc. is attenuated over that loop by frequency modification. The frequency modification is such that, at least for some signals, on each pass through the loop, the sound processing equipment will attenuate or amplify individual sub-bands of the frequency spectrum of the audio signal that is received at the input of the sound processing equipment. The frequency range of each individual sub-band is modified as it passes through the sound processing equipment, transformed into sound in the physical space, picked up again by the sound processing equipment, and then passes through again, so that the sub-band is attenuated on at least one of those passes through the sound processing equipment. The attenuation can be performed by configuring the sound processing equipment to amplify some input frequencies and shift those frequencies to other frequencies that the sound processing equipment is configured to attenuate.

An apparatus for generating volumetric images viewable without 3D eyewear. The apparatus includes an image display assembly displaying a first image at a first display time and a second image at a second display time (e.g., a number of planar or 2D images on a display screen/surface). The apparatus includes a flexible two-way mirror element (a varifocal beamsplitter). During operations, the first and second images from the display assembly are directed toward and then reflected from the back side of the mirror element. The apparatus also includes a hoop-shaped frame supporting a peripheral edge of the mirror element. A driver shakes the frame to resonate the mirror element between convex and concave shapes while it is used for reflecting the first and second images. The apparatus also includes a concave mirror positioned relative to the mirror element to receive the reflected first and second images.

A method and system of selectively projecting images is disclosed. An illuminated area is created on a projection surface by directing a light source to the projection surface. The illuminated area is detected with a camera. Electrical signals are transmitted from the camera to the projector, the electrical signals being indicative of the position of the illuminated area in relation to the projection surface. Based on the received electrical signals, an image and a second image are projected on the projection surface. The image is projected on the illuminated area of the projection surface. The second image is projected on an area of the projection surface that is not illuminated by the light source. Applications of this method and system include the projection of background and foreground images creating the illusion of an x-ray beam, the projection of a normal image and an overblown image creating the illusion of a magnifying light beam.
