Building a Haptic Dimension: The Science Behind the Taction Transporter

Haptic motors are finding applications in gaming, music, VR/AR, and therapeutic/wellness. The Transporter is a patented transducer that delivers faster more accurate bass and is designed to work with the main audio driver in headphones. It subtly vibrates against the user’s skin to produce an extra dimension that can be described as a high-fidelity extension. Silmon J. Biggs and John Steinberg, the two masterminds behind Taction Technology share the story of this development. This article was originally published in audioXpress, January 2023.
