Data processing systems for providing a data communication channel between one or more connected computing devices and an interactive display

A computer-implemented data processing method of modifying an on-screen display of an interactive display device that is operatively coupled to a display controller to include one or more first images from a first connected computing device while the interactive display device is displaying one or more incoming images from a second connected computing device, the second connected computing device being the currently selected video source for the interactive display device, the method comprising:

• configuring, by one or more computer processors, the first connected computing device as a first USB host device;
• configuring, by the one or more computer processors, a display controller device as a second USB host device;
• providing, by the one or more computer processors, a data communication channel between the first USB host device and the second USB host device;
• receiving, by the one or more computer processors, via a data communication channel between the first USB host device and the second USB host device, one or more pieces of data from the first connected computing device;
• generating, by the one or more computer processors, an on-screen display based at least in part on the one or more pieces of data;
• causing, by the one or more computer processors, the interactive display device to display the one or more incoming images from the second connected computing device;
• and
• causing, by the one or more computer processors, the interactive display device to superimpose the generated on-screen display over at least a portion of the one or more incoming images from the second connected computing device.

An interactive display system for integrating one or more pieces of data received from one or more connected computing devices into an onscreen display of an interactive display device operatively coupled to each of the one or more connected computing devices, the interactive display system comprising:

• one or more interactive display device processors;
• one or more touch-enabled input devices;
• and
• one or more USB relays, each of the one or more USB relays being operatively connected to the one or more interactive display device processors, wherein the one or more USB relays comprise a first USB relay, wherein:
• a first connected computing device of the one or more connected computing devices is configured as a first USB host device;
• the one or more interactive display device processors are configured as a second USB host device;
• the first USB relay is configured as a USB device to the both the first USB host and the second USB host and configured to form a communications channel between the first connected computing device and the one or more interactive display device processors, wherein the interactive display system is configured for:
• receiving, via the communications channel, one or more pieces of data at the first USB relay acting as the USB device to the first USB host from the first connected computing device;
• and
• passing, via the communications channel, by the first USB relay acting as the USB device to the second USB host, the received one or more pieces of data from the first USB relay through to the one or more interactive display device processors;
• generating, by the one or more interactive display device processors, an on-screen display based at least in part on the one or more pieces of data;
• causing, by the one or more interactive display device processors, the interactive display device to display one or more incoming images from a second connected computing device of the one or more connected computing devices;
• and
• causing, by the one or more interactive display device processors, the interactive display device to display the generated on-screen display along with the one or more incoming images from the second connected computing device.
