User interface manipulation in a foldable screen device
User interface (UI) manipulation techniques are disclosed that can allow a user device to hide and obscure sensitive information displayed on a flexible, foldable, or otherwise reconfigurable display from onlookers whilst maintaining or improving its accessibility exclusively to the primary user. Examples of the disclosed techniques can manipulate the UI in a way such that it is largely only viewable as intended when the user device is physically configured to a certain folding angle (and/or viewing angle). In some examples, the UI can be customized such that it promotes a certain device configuration (e.g., folding angle) that can provide an optimum security configuration for the user's current surroundings. The UI displayed on the display screen can change in form factor (e.g., an intended size as viewed by the user) to adapt to the current surroundings and/or based on the sensitivity in the displayed content.
1. A method for privately displaying information, the method comprising:
receiving an indication to display, on a mobile device, sensitive information, wherein the mobile device includes a foldable display;
determining a form factor for how the sensitive information is to be displayed, wherein the form factor is smaller than a full area of the foldable display;
generating, based on the determined form factor, a user interface to be displayed on the foldable display, wherein the user interface is to show the sensitive information in the form factor but visually deformed to a user unless the foldable display is manipulated to a select angle;
detecting, from a user-facing eye detector on the mobile device, a location of an eye of the user; and
adjusting the user interface in response to the detected location of the eye of the user.
2. The method of claim 1 , wherein the user interface is collectively displayed by a plurality of sections of the foldable display.
3. The method of claim 2 , wherein the foldable display is a bi-fold display.
4. The method of claim 1 , further comprising:
identifying a level of sensitivity of the sensitive information,
wherein the form factor is further determined based on, and inversely correlated to, the level of sensitivity.
5. The method of claim 1 , further comprising:
identifying, based on readings from one or more sensors on the mobile device, a level of privacy risk in a surrounding environment of the mobile device,
wherein the form factor is further determined based on the identified level of privacy risk.
6. The method of claim 5 , wherein the form factor is inversely correlated to the identified level of privacy risk.
7. The method of claim 1 , further comprising:
determining a folding angle for which, unless display sections of the mobile device are folded to the folding angle, the user interface appears distorted to the user,
wherein the user interface is further generated based on the determined folding angle.
8. The method of claim 7 , wherein the user interface is symmetrically deformed about an axis along a hinge of the foldable display.
9. The method of claim 1 , further comprising:
determining a viewing angle for which, unless the mobile device is oriented to the viewing angle relative to the user, the user interface appears distorted to the user,
wherein the user interface is further generated based on the determined viewing angle.
10. The method of claim 1 , wherein the user interface is adjusted so that a new viewing angle for the user interface reflects the detected location of the eye of the user.
11. The method of claim 1 , further comprising:
receiving, from one or more orientation sensors on the mobile device, a current orientation status of the mobile device,
wherein the user interface is adjusted further in response to the received current orientation status of the mobile device.
12. The method of claim 1 , further comprising:
generating, based on the select angle, a visual guidance indicium that guides the user to manipulate the foldable display to the select angle.
13. The method of claim 12 , wherein the visual guidance indicium appears to the user as a select geometric shape only when the foldable display is manipulated to the select angle.
14. The method of claim 1 , further comprising:
retrieving a current folding angle of the foldable display; and
generating, based on a difference between the current folding angle and the select angle, additional guidance that guides the user to manipulate the foldable display to the select angle.
15. The method of claim 1 , wherein the sensitive information is not shown in the user interface unless the foldable display is manipulated to the select angle.
16. The method of claim 1 , further comprising:
changing, based on the determined form factor, an original layout of the sensitive information to an alternative layout that is suitable for a smaller form factor as compared to the full area of the foldable display.
17. The method of claim 16 , wherein the original layout is for a display form factor designated for desktop computers, and wherein the alternative layout is for a display form factor designated for mobile devices.
18. The method of claim 1 , further comprising:
retrieving a current folding angle of the foldable display;
updating the form factor based on the current folding angle; and
adjusting the user interface to conform to the updated form factor.
19. The method of claim 18 , wherein the retrieving, updating, and adjusting steps are performed substantially in real time as the user manipulates the folding display.
20. A method for privately displaying information, the method comprising:
receiving an indication to display, on a mobile device, sensitive information, wherein the mobile device includes a flexible display;
determining a form factor for how the sensitive information is to be displayed, wherein the form factor is smaller than a full area of the flexible display;
generating, based on the determined form factor, a user interface to be displayed on the flexible display, wherein the user interface is to show the sensitive information in the form factor but visually deformed to a user unless the flexible display is manipulated to a select shape;
detecting, from a user-facing eye detector on the mobile device, a location of an eye of the user; and
adjusting the user interface in response to the detected location of the eye of the user.
21. The method of claim 20 , further comprising:
identifying a level of sensitivity of the sensitive information,
wherein the form factor is further determined based on, and inversely correlated to, the level of sensitivity.
22. The method of claim 20 , further comprising:
identifying, based on readings from one or more sensors on the mobile device, a level of privacy risk in a surrounding environment of the mobile device,
wherein the form factor is further determined based on the identified level of privacy risk.
23. The method of claim 20 , further comprising:
determining a folding angle and a folding line for which, unless display sections of the mobile device are folded to the folding angle and along the folding line, the user interface appears distorted to the user.
24. The method of claim 20 , further comprising:
generating, based on the select shape, a visual guidance indicium that guides the user to manipulate the flexible display to the select shape.
25. The method of claim 20 , further comprising:
retrieving a current shape of the flexible display; and
generating, based on a difference between the current shape and the select shape, additional guidance that guides the user to manipulate the flexible display to the select shape.
26. The method of claim 20 , further comprising:
retrieving a current shape of the flexible display;
updating the form factor based on the current shape; and

27. The method of claim 20 , further comprising:
generating, based on the select shape, a visual guidance indicium that guides the user to grip the flexible display in a manner that obstructs a portion of the flexible display.
28. A method for privately displaying information, the method comprising:
receiving an indication to display, on a mobile device, sensitive information, wherein the mobile device includes a foldable display;
