Ultrasonic discovery protocol for display devices

A method for displaying visual data over a plurality of display devices, the method comprising:

• configuring a processor to execute an ultrasonic discovery protocol;
• operatively coupling a primary display device to the processor, the primary display device being configured to transmit a first signal;
• operatively coupling a secondary display device to the processor, the secondary display device being configured to transmit a second signal;
• detecting a positional trigger event;
• executing the ultrasonic discovery protocol;
• transmitting, by the primary display device, the first signal, the first signal being an acoustic signal;
• receiving, by a microphone array of the secondary display device, the first signal;
• in response to receiving the first signal, transmitting, by the secondary display device to the primary display device, the second signal, the second signal encoding data that indicates a positional relationship between the primary display device and the secondary display device;
• and
• cooperatively displaying the visual data on the primary and secondary display devices based on the indicated positional relationship.

A computing system capable of displaying visual data over a plurality of display devices, the computing system comprising:

• a primary display device configured to transmit a first signal, the primary display device comprising a primary display and a processor configured to execute an ultrasonic discovery protocol;
• and
• a secondary display device configured to transmit a second signal, the secondary display device comprising a secondary display;
• the ultrasonic discovery protocol is programmatically executed upon detection of a positional trigger event;
• execution of the ultrasonic discovery protocol by the processor causes the primary display device to transmit the first signal, the first signal being an acoustic signal received via a stereoscopic microphone array of the secondary display device;
• in response to receiving the first signal, the secondary display device transmits the second signal to the primary display device, the second signal being an electric signal that encodes data indicating a positional relationship between the primary display device and the secondary display device;
• the primary and secondary display devices are configured to cooperatively display the visual data based on the indicated positional relationship;
• and
• the positional relationship of the primary and secondary display devices is defined by a grid template and determines a display mode for displaying the visual data.
