Abstract: A navigation system is configured to generate a sequence of driving instructions for directing a driver of a vehicle from a current location to a final destination. The navigation system is configured to capture sensor data that reflects the field of view of the driver and to identify objects in that field of view. The navigation system then customizes the driving instructions to reference specific objects, thereby generating context-specific driving instructions. The navigation system is also configured to identify particular objects upon which the driver is focused, and to generate context-specific driving instructions relative to such objects of focus. The navigation system may also provide correction information to the driver upon determining that the driver has incorrectly focused on a different object than an object referenced in a context-specific driving instruction.

Abstract: One embodiment of the present invention sets forth a technique for detecting when a user is not being attentive based on eye convergence. The technique includes determining a first distance from the user to a first object. The first distance may be determined using a depth sensor. The technique further includes determining a first vergence angle associated with a left eye of the user and determining a second vergence angle associated with a right eye of the user. The technique further includes determining a first eye convergence distance based on the first vergence angle, the second vergence angle, and an interocular distance between the left eye and the right eye. The technique further includes comparing the first distance to the first eye convergence distance to generate a first result. An inattention alert may be generated based on the first result.
