Auto-recovery for AR wearable devices

An augmented reality (AR) wearable device comprising:

• one or more processors;
• and
• a memory storing instructions that, when executed by the one or more processors, configure the AR wearable device to perform operations comprising:
• registering an uncaught exception handler;
• invoking a pass-through application as a background process, the pass-through application comprising an on-resume procedure;
• invoking an application as a foreground process;
• in response to detecting the application is unresponsive,
• invoking the on-resume procedure to switch the pass-through application as the foreground process from the background process, and
• causing, by the on-resume procedure, the application to be restarted as the foreground process and the pass-through application to be switched as the background process from the foreground process;
• and
• in response to an exception without an exception handler,
• invoking the uncaught exception handler as the foreground process,
• causing, by the uncaught exception handler, a process associated with the application to be terminated, and
• causing, by the uncaught exception handler, the application to be restarted as the foreground process.

A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a virtual reality (AR) wearable device, cause the AR wearable device to perform operations comprising:

• registering an uncaught exception handler;
• invoking a pass-through application as a background process, the pass-through application comprising an on-resume procedure;
• invoking an application as a foreground process;
• in response to detecting the application is unresponsive,
• invoking the on-resume procedure to switch the pass-through application as the foreground process from the background process, and
• causing, by the on-resume procedure, the application to be restarted as the foreground process and the pass-through application to be switched as the background process from the foreground process;
• and
• in response to an exception without an exception handler,
• invoking the uncaught exception handler as the foreground process,
• causing, by the uncaught exception handler, a process associated with the application to be terminated, and
• causing, by the uncaught exception handler, the application to be restarted as the foreground process.
