Task

To design several algorithms for the synthesis, encoding, and transmission of haptics (low-frequency vibrations) and pneumatics in car seats. The haptic signals are derived from the car entertainment audio and improve the sense of comfort for the driver and passengers.

Challanges

• The designed algorithms must be computationally efficient to fit within the constraints of the car entertainment DSP system.
• The algorithms must encode haptics and pneumatics efficiently to meet the data storage constraints of the car entertainment system.
• The project had tight delivery deadlines, as multiple partners were involved.

How we helped

• Creation and testing of novel haptic generation algorithms.
• Design of a new data compression scheme capable of encoding multiple channels of haptic and pneumatic information efficiently.
• Creation of reference designs in Python, AudioWeaver, and C-code.
• Porting some of the algorithms to an iOS app for customer-facing demonstration (Swift, C, and AudioKit).

Results

We advanced the technology and intellectual property of our client, Aurasens, who licenses their solutions to an OEM automobile equipment manufacturer and a well-known premium German car manufacturer. The technology that we helped create will be enbedded in cars produced from 2025.
