PULS8 is a shared musical experience for the deaf and hearing. Currently, musical experiences (concerts, mp3 players, instruments) are created exclusively for the hearing. Our solution is a system for listening, creating, and sharing that is inclusive of the hearing and non-hearing to form a shared musical experience. The PULS8 system enhances how deaf individuals traditionally experience sound to create a new musical movement.
PULS8 was created in collaboration with Christy Yang and Ian Dowling at the Art Center College of Design

To demonstrate a range of vibrational tones, we hacked devices ranging from cellphones to game controllers. After studying different motors we realized that we needed more articulate forms of haptic feedback.
A fundamental design consideration was to make the PULS8 necklace fashionable enough to wear. We designed the necklace to look and feel like jewelry, while remaining analogous to how people rest their headphones as a fashion statement. The haptic necklace is best experienced when contacted directly. It fits nicely underneath any top, to be revealed only when the listener decides to share it.
"The Steam Controller is built around a new generation of super-precise haptic feedback, employing dual linear resonant actuators. These small, strong, weighted electro-magnets are attached to each of the dual trackpads. They are capable of delivering a wide range of force and vibration, allowing precise control over frequency, amplitude, and direction of movement."
PULS8 utilizes linear resonant actuators to transpose music into physical vibrations. While this feedback is useful for haptic videogame controllers and subwoofers, it is adaptable to create hi-fidelity listening experiences. These actuators are small subwoofers that act as tactile transducers. The transducers relay the sensation of sound transmitted directly to the human body by physical contact, rather than by traditional sound waves that are heard through the ears.
After considering full body haptic experiences, the necklace was most effective in balancing an authentic haptic experience while managing a low-profile. A key challenge in designing a necklace is to avoid making it feel like a collar. The two halves come together to power the necklace on and begins to search for the PULS8 app via bluetooth.
The haptic necklace creates the resonance one feels when at a concert. PULS8 is driven by the rising popularity of bass music to create a shared experience between hearing and deaf individuals. Acoustic bass is felt through the chest and reverberates throughout the body. With the PULS8 necklace, the deaf and hearing feel music's beat and rhythm together.
