A wearable device may include a head-mounted display (HMD) for rendering a three-dimensional (3D) virtual object which appears to be located in an ambient environment of a user of the display. The relative positions of the HMD and one or more eyes of the user may not be in desired positions to receive, or register, image information outputted by the HMD. For example, the HMD-to-eye alignment vary for different users and may change over time (e.g., as a given user moves around or as the HMD slips or otherwise becomes displaced). The wearable device may determine a relative position or alignment between the HMD and the user's eyes by determining whether features of the eye are at certain vertical positions relative to the HMD. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, and provides feedback on the quality of the fit to the user, and may take actions to reduce or minimize effects of any misalignment.

An electronic device according to various embodiments may include: a housing including a first housing, a second housing, and a third housing; a first hinge configured to enable the first housing and the third housing to pivot, and a second portion configured to enable the second housing and the third housing to pivot; a first display viewable through a first area of the first housing, a second area of the second housing, and a third area of the third housing; at least one sensor; a processor operably connected to the first display and the at least one sensor; and a memory operably connected to the processor, wherein the memory may store instructions that, when executed, cause the processor to control the electronic device to: display a first screen of an application in a first state in which the first area and the second area face the third area, detect, through the at least one sensor, a change from the first state to a second state in which the first area and the third area face a same direction or a third state in which the second area and the third area face a same direction, determine a second screen of the application to be displayed through the first display in a state, among the second state and the third state, changed from the first state, and display the second screen through the first display in the changed state.

Provided are a display control adjustment method, a terminal, and a computer-readable storage medium. The method includes: selecting a display control to be adjusted from a current display interface; generating a control instruction according to a position of the display control to be adjusted with respect to the non-display region; and adjusting, according to the control instruction, the control region of the display control to be adjusted and a content display mode of the display control to be adjusted, so that display content in the display control to be adjusted is displayed in a display region of a display.

Disclosed in some examples are display systems, methods, devices, and machine-readable mediums which provide for a gesture-based method for specifying a region of a display in which to show shared content. Also disclosed are pairing methods for associating the region of the display with a content source device, methods for sharing content within the region, and methods for providing input from the region back to the content source device. Also disclosed in some examples are display systems, methods, devices, and machine-readable mediums which provide for notification handling for user interfaces.
