9. The computer system of claim 1 , wherein the device has a length not equal to a width, wherein a vertical display direction for the content corresponds to content displayed from a top to a bottom of the device along a longer side with a shorter side placed parallel to the ground, and wherein a horizontal display direction for the content corresponds to content displayed from the top to the bottom of the device along the shorter side with the longer side placed parallel to the ground.

10. The computer system of claim 9 , wherein changing a display direction for content displayed on the device further comprises:

changing the display direction from the horizontal display direction to the vertical display direction or from the vertical display direction to the horizontal display direction.

11. The computer system of claim 9 , wherein a vertical position of the device corresponds to a shorter side placed parallel to the ground and a horizontal position of the device corresponds to a longer side placed parallel to the ground, and

wherein when the device is in the horizontal device position and the horizontal display direction, the display includes a portion of the screen which is visible only when the device is in the horizontal device position, and which is not visible when the device is in the vertical device position.

12. The computer system of claim 9 , wherein a vertical position of the device corresponds to a shorter side placed parallel to the ground and a horizontal position of the device corresponds to a longer side placed parallel to the ground, and

wherein when the device is in the horizontal device position and the horizontal display direction, the display includes a portion of the screen which is cut off as compared to when the device is in the vertical device position and the vertical display direction.

13. The computer system of claim 1 , wherein the method further comprises:

receiving, by the client computing device, a voice command;

wherein starting the timer for the user-configured expiration time is in response to receiving the voice command.

14. A computer-implemented method for controlling display direction of content on a device, the method comprising:
