Abstract: Examples associated with interference generation are described. One example system includes a personal digital assistant. A listening device in the system may receive voice input to control the personal digital assistant. An interference generator integrated with the listening device may generate a noise pattern to prevent the listening device from receiving voice input. An interface for the interference generator may allow a user to activate and deactivate the interference generator and provide a visual indicator describing whether the interference generator is active.

Abstract: In some examples, a display can modify brightness of displays using pixel luminance by detecting a luminance of pixels included on the display, and modifying a screen brightness of the display by modifying a brightness of a backlight of the display within a predetermined time when the detected luminance of the pixels on the display exceeds a predetermined luminance threshold.
