Content segmentation and navigation

Content can be segmented into selectable sections for use with viewing devices such as virtual reality (VR) or three-dimensional (3D) headsets. Content to be displayed using such a device can be analyzed (dynamically or offline) to identify segments of the content. The content can be identified by, for example, locating existing segmentations, identifying regions having a minimum size, or identifying regions running along edges or full lengths/widths of the content, etc. A user can utilize a single device input to cause any of these sections to become a current focus of the display. As a current focus, the user can navigate, scroll, or otherwise manipulate the content or view within that section. Different types of input (i.e., a single or double tap, or long press) can be used to switch focus, interact with various elements, or perform other such actions.
