Driver Assistive system based on Spatial Audio Rendering and Auralization

Modern roads are increasingly complex environments requiring drivers to process vast amounts of information. Existing driver-assist systems predominantly rely on visual and haptic feedback, diverting the driver’s attention from the road and increasing cognitive load. The proposed project introduces a driver-assist technology leveraging spatial audio rendering technology. This system delivers real-time auralization and auditory feedback to the drivers through binaural speakers mounted on the driver’s seat headrest. By using data from built-in cameras, LiDARs, RADARs, and other sensors, the system creates a spatial soundscape to alert the driver of surrounding road traffic-vehicles, pedestrians, bicycles, motorbikes, and other road objects by rendering spatial audio cues. Unlike traditional driver-assist systems, which rely on visual and haptic feedback, this system minimizes the need for visual focus on dashboards, enabling the driver to remain attentive to the road. This proposal outlines the technical components, algorithms, methods, and necessity for this technology, along with a detailed flowchart of the process.
The proposed system will:
• Enable drivers to localize road users aurally, such as vehicles, pedestrians, and bicycles.
• Provide non-intrusive alerts that reduce dependency on visual or haptic feedback.
• Enhance road safety by improving driver reaction time and situational awareness.

Objectives

- Detect and classify all relevant road users (vehicles, pedestrians, bicycles)
- Provide real-time spatial audio feedback via headrest speakers.
- Prioritize alerts based on proximity and collision risk.
- Minimizes distractions by eliminating the need for visual displays or physical feedback
- Aligns with natural human auditory capabilities, improving reaction times
- Offers a seamless, immersive experience, making road navigation safer and less stressful
