Level 1 - Driver Assistance

Goal

When drivers face heavy traffic, finding an alternate route can be stressful and difficult, especially if using a phone or navigation system. My system addresses this by suggesting potential re-routes while allowing users to adjust them according to their preferences. For instance, if the system suggests highways but the driver prefers to avoid them, they can choose a more suitable route.

Design

The design focuses on efficiently notifying drivers of heavy traffic and suggesting alternate routes. Traditional navigation systems require manual input, which is unsafe. My system uses voice assistance and a small screen on the windshield to display hazard icons and faster route options. Drivers can navigate these options using the up and down arrows on the steering wheel, with an automated voice reading each option. A confirmation message on the windshield will inform the driver of the current route status.

Plan to Specify Gap

My design bridges the gap between ‘Plan’ and ‘Specify’ by allowing the car to verbally provide route options and enabling drivers to select them using steering wheel buttons. This ensures safety by eliminating the need to manually search for routes.

Supporting the Gulf of Evaluation

Perceiving the State of Interaction
The system displays a progress bar showing the new route loading and a checkmark once re-routing is complete.

Interpreting the State of Interaction
A small label on the windshield confirms the new route, indicating it has successfully re-routed to avoid traffic.

Evaluating the Outcome
Users can see and hear that their route has been updated, confirming the system's response to traffic.

Situation Awareness

The car enhances situational awareness by displaying route information on the windshield, allowing the driver to switch routes without looking away from the road. Traffic issues are addressed verbally, and the driver can use the steering wheel to choose alternate routes. After selecting a route, the car confirms the choice and informs the driver of the new route duration.
