Gesture-based alignment methodology to extend the viewport on adjacent touch screen devices

A viewport controller system for displaying an image on a plurality of devices, the system comprising a memory and a processor that is adapted to:

• receive data characterizing a first touch sensitive display having a first edge, a center location (x1, y1), and a dimension A1 in a first orientation that is perpendicular to the first edge;
• receive data characterizing a second touch sensitive display having a second edge, a center location (x2, y2), and a dimension A2 in the first orientation, wherein the first and second edges are physically separated from each other;
• map portions of a global image to each of the first and second touch sensitive displays, wherein the center location (x1, y1) is mapped to a first pixel in the global image;
• map the center location (x2, y2) to a second pixel in the global image, wherein a difference between the first and second pixels in the first orientation is 0.5×(A1+A2);
• send, to a first processor associated with the first touch sensitive display, a first portion of the global image to be displayed on the first touch sensitive display, such that the first pixel of the global image is displayed at the center location (x1, y1) of the first touch sensitive display;
• and
• send, to a second processor associated with the second touch sensitive display, a second portion of the global image to be displayed on the second touch sensitive display, such that the second pixel of the global image is displayed at the center location (x2, y2) of the second touch sensitive display.

A computer program product including one or more non-transitory machine-readable mediums encoded with instructions that when executed by one or more processors cause a process to be carried out, the process comprising:

• receiving data characterizing a first touch sensitive display having a first edge, a center location (x1, y1), and a dimension A1 in a first orientation that is perpendicular to the first edge;
• receiving data characterizing a second touch sensitive display having a second edge, a center location (x2, y2), and a dimension A2 in the first orientation, wherein the first and second edges are physically separated from each other;
• mapping portions of a global image to each of the first and second touch sensitive displays, wherein the center location (x1, y1) is mapped to a first pixel in the global image;
• mapping the center location (x2, y2) to a second pixel in the global image, wherein a difference between the first and second pixels in the first orientation is 0.5×(A1+A2);
• sending, to a first processor associated with the first touch sensitive display, a first portion of the global image to be displayed on the first touch sensitive display, such that the first pixel of the global image is displayed at the center location (x1, y1) of the first touch sensitive display;
• and
• sending, to a second processor associated with the second touch sensitive display, a second portion of the global image to be displayed on the second touch sensitive display, such that the second pixel of the global image is displayed at the center location (x2, y2) of the second touch sensitive display.
