Apple has been granted a patent (number 9,644,983) for “simplified audio navigation instructions” that hints at future features for its Maps app for macOS and iOS and perhaps tweaks to CarPlay.
Compatible with the iPhone 5 and later models, CarPlay provides a simplified way to use your iPhone interface on a car’s touch screen, giving users access to Siri voice controls, as well as Apple Maps, Apple Music, Phone, Messages, and a variety of third party apps.
According to Apple’s patent, a mobile device can be configured to provide simplified audio navigation instructions that can provide a reduced set of audio navigation instructions so that the audio instructions are only presented to the user when the user wishes to or needs to hear the instructions.
You can enable the simplified audio navigation instructions or they can be enabled automatically. The instructions can be configured with rules for when to present audio navigation instructions. For example, the rules can specify that audio navigation instructions are to be provided for complex road segments, a user defined portion of a route, or specified road types, among other criteria. The mobile device can be configured with exceptions to the rules such that audio navigation instructions can be presented when the user has, for example, deviated from a defined route.
Of course, Apple files for — and is granted — lots of patents by the U.S. Patent & Trademark Office. Many are for inventions that never see the light of day. However, you never can tell which ones will materialize in a real product.
