Good Chime
Use case
The user will encounter various waypoints on their route and may need to adjust their path accordingly. These sounds indicate that a user has taken the correct action. They will occur at the end of an interaction when the user receives information about navigation, obstacles, danger, or trip arrival.
System feedback
Short chime:
When a user completes actions needed to avoid obstacles or navigate, they will hear a stereo harp sound to indicate that they were successful, and no further immediate action is required. This chime lasts for 2 seconds.
Long chime:
As a user arrives at their destination, a stereo harp sound will play to indicate that they have arrived at their final destination, and the navigation instructions are complete. This chime lasts for 8 seconds.
Sound files

Good chime in action
Imagine you are traveling to a coffee shop and hear the sound of a trash can on your left with a vibration in your right wrist steering you away from the obstacle. Upon moving, you hear a “short chime” that lets you know you’ve avoided the obstacle. A moment later, you hear that you are approaching your destination at your “11 O’ Clock”. You turn your body slightly to the left and move forward. As you reach the door, you hear a longer harp sound letting you know you have arrived at your destination.
User requirements

Input system requirements
Identify objects
Various sensors are used to detect objects. The system will uses a combination of computer vision, virtual tags, and crowd sourced data to identify object details like size, location and type. Objects may include obstacles, points of interest or on-demand info.
Direction + distance
Sensors detect the direction and measure the angle and distance between the user and the detected obstacle to ensure the obstacle is no longer in the user’s projected path.
This information is also used to ensure the user is heading down the correct path when following navigation instructions.
Location
Location and camera imagery is used to ensure the user is at the final destination before indicating that the user has arrived at their final destination.
This information is also used to ensure the user successfully completes the task such as crossing the street, taking the correct turn, and making progress toward their final destination.
