Abstract

Systems, methods, and apparatuses describe a display and control circuitry configured to modify the display. The display comprises a plurality of pixels corresponding to a plurality of subsets of the display and a plurality of MEMS actuators configured to modify the orientations of the pixels. The control circuitry may be configured to cause each respective MEMS actuator to control an orientation of a respective pixel of the plurality of pixels by causing a subset of the plurality of MEMS actuators to modify orientations of a corresponding first subset of the plurality of pixels associated with a first viewing position in an environment of the display. The control circuitry may be further configured to cause the first subset of the plurality of pixels having the modified orientations to display particular content directed to the first viewing position, wherein the particular content is obscured from a second viewing position of the environment.

First claim

What is claimed is:

a MEMS rod configured to enable a height of the respective pixel to be adjusted, and
wherein the control circuitry is further configured to cause the first subset of the plurality of MEMS actuators to modify the orientations of the corresponding first subset of the plurality of pixels associated with the first viewing position in the environment of the display based at least in part on adjusting a height of at least one pixel of the first subset of the plurality of pixels using at least one MEMS rod.

2 . The system of claim 1 , wherein the particular content is a first content item, and wherein the control circuitry is further configured to:
cause a second subset of the plurality of MEMs actuators to modify orientations of a corresponding second subset of the plurality of pixels associated with the second viewing position in the environment of the display; and cause the second subset of the plurality of pixels to display a second content item directed to the second viewing position, wherein the second content item is obscured from the first viewing position of the environment that is associated with the first subset of the plurality of pixels, wherein the first viewing position is different from the second viewing position, and the second content item is different from the first content item.

3 . The system of claim 2 , wherein the control circuitry is further configured to:
cause a third subset of the plurality of MEMs actuators to modify orientations of a corresponding third subset of the plurality of pixels associated with a third viewing position in the environment of the display; cause the third subset of the plurality of pixels to display a third content item directed to the third viewing position, wherein the third content item is obscured from the first viewing position and the second viewing position of the environment; cause a fourth subset of the plurality of MEMs actuators to modify orientations of a corresponding fourth subset of the plurality of pixels associated with a fourth viewing position in the environment of the display, and cause the fourth subset of the plurality of pixels to display a fourth content item directed to the fourth viewing position, wherein the fourth content item is obscured from the first viewing position, the second viewing position, and the third viewing position of the environment.

4 . The system of claim 3 , wherein the control circuitry is further configured to:
cause a fifth subset of the plurality of pixels to display content without controlling MEMS actuators corresponding to the fifth subset of the plurality of pixels to modify orientations of the fifth subset of the plurality of pixels, wherein the particular content is directed to the first viewing position, the second viewing position, the third viewing position, and the fourth viewing position of the environment.

5 . The system of claim 4 , wherein the display is integrated on a tabletop of a gaming device.

6 . The system of claim 2 , wherein the control circuitry is further configured to:
cause the display to operate in a first mode and a second mode, wherein in the first mode:
the control circuitry causes the first subset of the plurality of MEMS actuators to modify the orientations of the corresponding first subset of the plurality of pixels associated with the first viewing position in the environment of the display, to cause the particular content to be directed to the first viewing position and to cause the particular content to be obscured from the second viewing position; and
wherein in the second mode:

7 . The system of claim 2 , wherein the first subset of the plurality of pixels and the second subset of the plurality of pixels are arranged in:
alternating rows between the first subset of the plurality of pixels and the second subset of the plurality of pixels; alternating columns between the first subset of the plurality of pixels and the second subset of the plurality of pixels; or a checkered pattern between the first subset of the plurality of pixels and the second subset of the plurality of pixels.
