## Abstract

Systems and methods for adjusting light emitted from a display of a device are provided. The adjusting includes obtaining, from light of an environment detected by at least one sensor, a measured color of light of the environment, and obtaining, from light of the environment detected by at least one sensor, a measured brightness of light of the environment. In response to the obtaining the measured color and the measured brightness of light, a color of light emitted from the display is adjusted from an initial color to a target color. A brightness of light emitted from the display is adjusted from an initial brightness to a target brightness.

### Claim 3 (depends on 1)

The method of claim 1, wherein the target color of the light matches the measured color of the light.

### Claim 4 (depends on 1)

The method of claim 1, wherein the defined offset brightness is between 0.1% and 10% of the measured brightness of the light.

### Claim 5 (depends on 1)

The method of claim 1, wherein causing the plurality of transitions to occur comprises the first transition and the second transition being caused to be performed simultaneously.

### Claim 6 (depends on 1)

The method of claim 1, wherein the computerized device is a display assistant device comprising a plurality of microphone holes and a sensor opening for the one or more sensors, wherein the plurality of microphone holes and the sensor opening are arranged in a top bezel area of the display.

### Claim 7 (depends on 1)

The method of claim 1, further comprising:
after causing the plurality of transitions to occur, determining, by the computerized device, that a user is engaged with the computerized device;
based on determining that the user is engaged with the computerized device, adjusting the brightness of light emitted from the display from the target brightness to a brightness level that exceeds the target brightness;
after adjusting the brightness of light emitted from the display to the brightness that exceeds the target brightness, determining, by the computerized device, that the user is no longer engaged with the computerized device; and
based on determining that the user is no longer engaged with the computerized device, adjusting the brightness of light emitted from the display back to the target brightness from the brightness level.

### Claim 8 (depends on 7)

The method of claim 7, wherein the user being engaged with the computerized device comprises a vocal interaction.

### Claim 9 (depends on 1)

The method of claim 1, further comprising:
after causing the plurality of transitions to occur, determining that a second brightness of the light measured using the one or more sensors satisfies a first threshold brightness value; and
in response to determining that the second brightness of the light measured using the one or more sensors satisfies the first threshold brightness value, presenting predetermined information on the display.

### Claim 10 (depends on 1)
