Abstract

This publication describes systems and techniques for a computing device that includes multiple touch screens that enables a user to cause the computing device to update the graphical user interface (GUI) being outputted by a first touch screen of the computing device by providing gesture input at a second touch screen of the computing device. For example, a mobile computing device, such as a foldable smartphone, may include two touch screens that can be folded up to 360 degrees so that the two touch screens face away from each other in a back-to-back position. When such a mobile computing device is being used by a user, a first touch screen may face towards the user while a second touch screen may face away from the user. As the first touch screen of the mobile computing device outputs content that is viewable by the user, the user may interact with the second touch screen of the mobile computing device, such as by providing or performing touch input (e.g., gesture input) at the second touch screen to cause the mobile computing device to change, modify, or update the content outputted by the first touch screen. For example, the user may perform a gesture input at the second touch screen that causes the mobile computing device to zoom in and/or out of content displayed at the first touch screen. By enabling the user to interact with the second touch screen of the mobile computing device to change, modify, or update the content outputted by the first touch screen of the mobile computing device, the mobile computing device allows the user to interact with the computing device via touch-based input without the user’s finger occluding the user’s view of content being outputted by the first touch screen of the computing device.
