Interfacing between digital assistant applications and navigation applications

A computer program product comprising one or more non-transitory computer-readable storage media having program instructions collectively stored on the one or more computer-readable storage media, the program instructions executable to:

• receive an input audio signal detected by a sensor of a client device while a display of the client device is rendering a viewport of a navigation application, the viewport displaying a first reference frame corresponding to a first geographic region;
• identify, based on the input audio signal, a request and a referential word;
• determine that the identified referential word is classified as a distal word;
• in response to determining that the referential word is classified as the distal word, identify a subset of point locations corresponding to a second geographic region that is currently outside the viewport of the navigation application;
• identify, based on the request, a specific point location from the identified subset of point locations;
• and
• cause the navigation application to display the specific point location within a second reference frame corresponding to the second geographic region.

A system comprising:

• a processor, a computer-readable memory, one or more computer-readable storage media, and program instructions collectively stored on the one or more computer-readable storage media, the program instructions executable to:
• receive an input audio signal detected by a sensor of a client device while a display of the client device is rendering a viewport of a navigation application, the viewport displaying a first reference frame corresponding to a first geographic region;
• identify, based on the input audio signal, a request and a referential word;
• determine that the identified referential word is classified as a distal word;
• in response to determining that the referential word is classified as the distal word, identify a subset of point locations corresponding to a second geographic region that is currently outside the viewport of the navigation application;
• identify, based on the request, a specific point location from the identified subset of point locations;
• and
• cause the navigation application to display the specific point location within a second reference frame corresponding to the second geographic region.
