A system and method for forming a micro-object density distribution (how densely micro-objects are assembled in a particular spatial region) are provided. [Solution] A high-speed camera tracks the existing object density distribution. An array of phototransistor-controlled electrodes is used to generate a dynamic potential energy terrain for manipulating objects with both DEP and EP forces, and a video projector is used to actuate the array. One or more computing devices are used to process images captured by the camera, estimate the existing density distribution of objects, receive a desired density distribution of micro-objects, define a model that describes the variation in micro-object density over time due to capacitance-based interactions, generate an array of electrode potentials that minimizes the error between the existing density distribution and the desired density distribution, and use the array of electrode potentials to actuate the electrodes.

A transparent projection display system for video conferencing and collaborative communication is provided. The system comprises a transparent projection screen of clear material, a video projector configured to project images onto the front side of the screen, and a camera disposed behind the screen for capturing video of a user on the front side. To maximize the brightness of the projected image as viewed by the user while substantially preventing the camera from capturing the projected image transmitted through the screen, the system includes a reflective layer disposed on the front side of the projection screen and a microlouver film disposed on the rear side. The reflective layer is configured to reflect the projected image toward the user, and the microlouver film comprises an array of louvers that block transmission of the projected image to the camera except along a narrow viewing angle aligned with the camera's optical axis. This arrangement enables the camera to capture a clear user image through the screen while suppressing the capture of projected content, thus supporting natural, aligned eye contact and high-quality video communication.

A system for video conferencing comprises a video projector and a transparent projection screen of clear material. A behind-display camera captures a video image through the transparent projection screen of a user located on the front side of the screen. To optimize the brightness of the projected video image (as viewed by the user) while preventing the behind-display camera from capturing that same projected video image transmitted through the screen, a series of optical layers in the form of films and / or coatings are included in the optical path between the projector and the camera. The series of optical layers may comprise a first linear polarizer, a partially reflective layer or dispersion layer, and a second linear polarizer. The first and second linear polarizers are orthogonal to one another, i.e., their axes are oriented 90 degrees to one another to block the projected image from being received by the camera. In a front projection arrangement, the partially reflective layer is designed to reflect a bright projected image to the user while permitting ambient light on the user's side to transmit to the camera. In a rear projection arrangement, the dispersion layer is designed to transmit a bright projected image to the user while permitting ambient light on the user's side to transmit through to the camera.
