Input device event processing

A non-transitory computer storage medium encoded with instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:

• receiving one or more input device events for navigating content presented on a graphical user interface;
• storing the one or more input device events in an event queue, the event queue including one or more GUI events relating to the graphical user interface (GUI), wherein the input device events and the GUI events are of different types, and wherein the GUI events are stored in a first portion of the event queue while the input device events are stored in a second portion of the event queue that is distinct from the first portion;
• processing the one or more GUI events stored in the event queue using a first processing thread and processing the one or more input device events from the event queue using a second processing thread;
• determining a stall in the processing by the first processing thread;
• storing input device events received after determining the stall in the processing by the first processing thread in a second event queue;
• and
• processing the input device events from the second event queue using the second processing thread.

• determining a stall in the processing of the one or more input device events and the one or more GUI events by the first processing thread;
• in response to determining the stall:
• storing input device events received after the stall in a second event queue;
• and
• spawning a second processing thread, wherein the second processing thread processes the one or more input device events from the second event queue.

A system comprising:

• one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
• receiving one or more input device events for navigating content presented on a graphical user interface;
• storing the one or more input device events in an event queue, the event queue including one or more GUI events relating to the graphical user interface (GUI), wherein the input device events and the GUI events are of different types, and wherein the GUI events are stored in a first portion of the event queue while the input device events are stored in a second portion of the event queue that is distinct from the first portion;
• processing the one or more input device events and the one or more GUI events stored in the event queue using a first processing thread;
• determining that a stall has occurred in the processing of the one or more input device events and the one or more GUI events by the first processing thread;
• in response to determining the stall:
• storing input device events received after the stall in a second event queue;
• and
• spawning a second processing thread, wherein the second processing thread processes the one or more input device events from the second event queue.
