System for determining positional relationships between display devices

Abstract:

Devices having touchscreen displays or other types of sensors may be placed adjacent to one another to form a larger display area for content. A relative position and alignment between these adjacent devices are determined using a touch gesture by a user. For example, a user may draw a line, circle, or other shape that provides input to the touch sensors of the devices. Touch data received from each device indicates the coordinates where contact was provided to the touch sensor. By matching the coordinates positioned near the borders of adjacent devices based on the time of their input, the relative position and alignment between the devices is determined. A corresponding portion of the content is provided to each device based on its relative position and alignment to form a consistent display area.
