Abstract

In one or more embodiments, a display device may display information via light emissions via a first orientation, and an anisotropic material, of the display device, may obscure the information along a first axis of the display device and within a first threshold angle. In one or more embodiments, it may be determined that the first orientation changes to a second orientation, and in response, the anisotropic material may obscure the information along a second axis of the display device and within a second threshold angle. In one or more embodiments, the anisotropic material may permit information along the first axis of the display device to be viewed by a person. In one or more embodiments, determining that the first orientation changes to the second orientation may be based at least on data from at least one of an electronic accelerometer, an electronic gyroscope, and an electronic magnetometer.
