Electronic display systems having mobile components

A display system comprising:

• a first mobile unit comprising:
• a receiving surface for receiving a first user interaction at an interaction point on the receiving surface, the receiving surface having a plurality of points corresponding to a plurality of points in a display image external to the receiving surface, wherein coordinates of the interaction point on the receiving surface map to corresponding coordinates of an action point on the display image;
• and
• a pattern on the receiving surface mapping to coordinates of the plurality of points on the receiving surface;
• wherein the first user interaction at the interaction point on the receiving surface of the first mobile unit is translatable into a first operation at the action point on the display image;
• and
• a second mobile unit configured to receive a second user interaction translatable into a second operation on the display image.

A computer-implemented method comprising:

• accessing coordinates of an interaction point of a user interaction performed on a receiving surface, the receiving surface being absent an electronic display, and the coordinates being determined based on analysis of a captured image of a position-coding pattern on the receiving surface;
• mapping, with a computer processor, the interaction point on the receiving surface to an operational point on a display image that is remote from the receiving surface;
• performing an operation at the operational point on the display image to update the display image, the operation corresponding to the user interaction at the interaction point of the receiving surface;
• repeatedly updating the display image in real time in response to a plurality of additional user interactions performed on the receiving surface.

A display system comprising:

• a mobile unit comprising:
• a receiving surface for receiving a first user interaction translatable into an action on a display image remote from the receiving surface;
• and
• a first position-coding pattern on the receiving surface, the first position-coding pattern being detectable by a first instrument for identifying an interaction point of the instrument on the receiving surface, wherein the interaction point maps to an action point on the display image;
• and
• a display surface configured to receive the display image, the display surface having a second position-coding pattern detectable by a second instrument.
