Goal
The driver's goal is to successfully find a parking spot and parallel park. The parallel parking action should be easy to execute in a short amount of time.
Gulf of Execution
The car will provide an alert when it locates a parallel parking spot. This alert will ask if the driver would like to park in that spot. Once the driver accepts this parking spot, the interface will provide a diagram for how the car will parallel park in the spot. It will ask the driver to manually put the car in reverse, which will start a sound signifying that the car is beginning to park. While the car is moving into the spot, the driver can follow along by watching the diagram and observing the backup camera to ensure that it is parking safely. Through the alert, the diagram, and the sound, the interface is supporting the Gulf of Execution through using mental models and signifiers to show the user how to parallel park.
Gulf of Evaluation
In order to support the Gulf of Evaluation, the car will use feedback to indicate to the driver the success of the parking job. This feedback will come in the form of an alert, which pops up on the screen after the car has finished parking. The feedback will either say “Success” or “Try again”, along with providing the reason why the driver should try parking again. To provide feedback, the car will first perceive the current state of the car by using sensors to determine how close the car is to the curb and surrounding cars. It will then calculate the distance and determine if the car is safely parked and out of the way of incoming traffic. Finally, it will give the alert to the driver to provide feedback on the success of the parking job.
Situation Awareness
Our car interface features a detailed view of the car’s surroundings including cars passing by and other objects in proximity. While the driver is interacting with the interface, they can see the rest of the activity happening around the car, which will alert them of any threats to collision on the other side of the car. Parallel parking can be a dangerous activity since the car must spend time in the way of passing vehicles. The 360 degree visualization in the interface prevents the driver from being unaware of tier blind sides while in a vulnerable position. Also, the display will read the captions for the action to the driver while they park in order to let them know the state of the system. If an error occurs, there will be beeping, and once the parking is successful, there will be an upbeat chime.
