Abstract

The subject disclosure relates to systems and methods for casting an application from a source device to a destination device. In particular, a process can include steps for causing a source application executing as a foreground process in an operating system of a source computing device to store state data, transmitting the state data of the source application to a set of destination computing devices, and transmitting a cast command to the destination computing device, where the cast command is configured to instruct the destination computing device to execute the source application on the destination computing device using the state data.

receiving, in response to user input received during an execution of a source application executing as a foreground process on an operating system of a source computing device, an invocation command;

in response to the invocation command;

causing a casting application process to execute as a foreground process of the operating system of the source computing device and thereby cause the source application to execute as a background process of the operating system of the source computing device, and

causing the source application to backup state data of the source application that indicates a set of properties of the source application execution at a first time;

capturing a screenshot of the source computing device executing the source application;

transmitting the state data to a set of destination computing devices via a server that synchronizes the state data with the set of destination computing devices;

displaying a selection menu representing each of the set of destination computing devices using the screenshot as a background image, wherein the selection menu is provided by the casting application process executing as a foreground process; and

transmitting, in response to a user selection of a destination computing device from the selection menu, a cast command to the destination computing device instructing the destination computing device to execute the source application on the destination computing device using the state data, whereby a user of the destination computing device can continue uninterrupted execution of the source application on the destination computing device at a second time.

2. The computer-implemented method of claim 1, further comprising causing the source application to resume execution as a foreground process after transmitting the cast command to the destination computing device.

3. The computer-implemented method of claim 1, further comprising terminating execution of the source application after transmitting the cast command to the destination computing device.

receive an invocation command in response to user input received during execution of the source application as a foreground process; and

in response to the invocation command, cause a casting application process to execute as a foreground process of the operating system, and thereby cause the source application to execute as a background process of the operating system and cause the source application to store state data of the source application.

9. The system of claim 7, wherein the memory further includes instructions that, when executed by the processor, enable the processor to:

issue a backup command, in response to user input received during execution of the source application as a foreground process, that causes the source application to back up state data of the source application.

10. The system of claim 7, wherein the memory further includes instructions that, when executed by the processor, enable the processor to:

conduct initial determinations comprising at least one selected from a group consisting of determining whether an application is executing as a foreground process, determining what application is executing as a foreground process, determining a version of an application executing as a foreground process, determining whether an application executing as a foreground process supports appcasting, and determining whether user preferences allow for appcasting of an application executing as a foreground process.

11. The system of claim 7, wherein the memory further includes instructions that, when executed by the processor, enable the processor to:

capture a display frame of the source application depicting the source application executing as a foreground process; and

display the display frame as a background image for the selection menu.

12. The system of claim 7, wherein the memory further includes instructions that, when executed by the processor, enable the processor to:

determine the subset of destination computing devices based on physical proximity of each destination computing device of the set of destination computing devices to the source computing device.
