User interfaces and methods for displaying content

A device comprising:

• a non-transitory medium storing an image and a mask;
• a processing unit to receive a user input, the user input indicating that a portion of the image is desired to be viewed by a user;
• and
• a screen operable by the processing unit to display the portion of the image in a viewing window in response to the user input while preventing public viewing of a remaining portion of the image by covering the remaining portion of the image using at least a part of the mask;
• wherein the processing unit is configured to translate an entirety of the viewing window relative to the mask in response to a movement of a finger of the user while the finger is placed against the screen;
• wherein a relative position of the viewing window with respect to a finger-contact location on the screen remains the same during at least a part of the movement of the finger while the finger is placed against the screen;
• and
• wherein the relative position of the viewing window with respect to the finger-contact location is adjustable, and wherein an entirety of the viewing window is offset from the finger-contact location to prevent the finger from blocking the image being displayed in the viewing window.

A program product that includes a non-transitory medium usable by a processing unit, the non-transitory medium having a set of stored instructions, an execution of which by the processing unit causes a process to be performed, the process comprising:

• receiving a user input at the device, the user input indicating that a portion of the image is desired to be viewed by a user;
• in response to the user input, displaying on the screen of the device the portion of the image while preventing public viewing of a remaining portion of the image by covering the remaining portion of the image using at least a part of the mask, wherein the portion of the image is displayed in a viewing window;
• and
• translating an entirety of the viewing window relative to the mask in response to a movement of a finger of the user while the finger is placed against the screen;
• wherein a relative position of the viewing window with respect to a finger-contact location on the screen remains the same during at least a part of the movement of the finger while the finger is placed against the screen;
• and
• wherein the relative position of the viewing window with respect to the finger-contact location is adjustable, and wherein an entirety of the viewing window is offset from the finger-contact location to prevent the finger from blocking the image being displayed in the viewing window.
