Abstract: An electronic device may include an ambient light sensor that measures ambient light color, a projector that projects ambient-light-matching illumination onto a surface, a user input device such as a microphone that gathers user input, and a position sensor that measures a position of the surface, a user, and/or a real-world object relative to the device. The ambient-light-matching illumination may create illuminated regions on the surface that blend in with the surrounding ambient light. Certain pixels in the projector may be turned off to create one or more unilluminated regions within the illuminated regions. The unilluminated regions may form apparent shadows. Control circuitry in the electronic device may adjust characteristics of the unilluminated regions by dynamically adjusting which pixels are turned off based on voice input, gesture input, and/or other sensor data.

Abstract: A levitator is disclosed. The levitator may include a repulsion wire coil having a vertical coil axis, a position control wire coil having a vertical coil axis, a rotation control wire coil having a horizontal coil axis, and a controller coupled to each of the repulsion wire coil, position wire coil, and rotation wire coil, where the controller is configured to independently control currents provided to each of the repulsion wire coil, position wire coil, and rotation wire coil to levitate an item.
