Project Title: Enhancing Driver Safety through Steering Wheel Switch (SWS) Design - Volvo EX90

Goal:

The goal of this project was to enhance driver safety by preventing drivers from attempting to interact with the non-touch screen behind the steering wheel in the new Volvo EX90. This issue arose after the implementation of two new screens in the car, one of which was a touch screen resembling the Tesla design.

Process:

To address this safety concern, the UX research team conducted prototype testing at Volvo's headquarters in Gothenburg, Sweden. The testing took place in the Open Innovation Arena within the R&D section.

• Prototype Testing:

  • Participants: Approximately 30 individuals from various departments, including finance, legal, and other non-technical areas, were involved.

  • Prototype Description: Participants were given a prototype of the Volvo EX90, unaware of the specific focus of the test.

  • Testing Scenario: Participants were asked to interact with the prototype as they would with a real vehicle.

  • SWS Design: A new button labeled "OK" was added to the steering wheel switch (SWS).

  • Testing Duration: The testing was conducted over three days.

Insight:

The introduction of the "OK" button on the steering wheel switch effectively redirected users from attempting to interact with the non-touch screen behind the steering wheel.

Result:

The outcome of the testing was overwhelmingly positive. Nearly all participants instinctively pressed the "OK" button when prompted, indicating a successful design intervention.

Benchmark:

• The benchmark for success was set at a high standard, aiming for a significant reduction in attempts to interact with the non-touch screen.

• The introduction of the "OK" button on the steering wheel switch exceeded expectations, demonstrating its effectiveness in preventing driver distraction and maintaining Volvo's commitment to safety.
