An Exploratory Haptic Music Experience
Sonohaptics is a wearable device that enhances the music experience for music lovers, hard-of-hearing people, and curious individuals who have the desire to try unusual haptic-music sensations.
Team members: Mariana Tamashiro, Purnendu, Rona Sadan
Context: Graduate project - Haptic interfaces
Tools used: Arduino IDE, Adobe Illustrator, Laser cutter machine
Advisor: Dr. Daniel Leithinger
Pressure waving pneumatic design process
We designed two waist straps made of six pneumatic pouches each, and one back strap. The straps and pouches were made of TPU coated Nylon fabric, heat-sealed with pieces of baking sheets.
+First step: Iterating on different pouches patterns with trash bags.
+Second step: Prototyping the chosen pattern from the Nylon fabric. We used the laser cutter to cut both the straps and the baking sheet patterns. The straps are 28in width X 3in height, divided into two separate sides of 13 in each (we left one inch in the middle for wiring).
We have inserted 4 tubes for each one of the pouches and connected the fifth tube to the upper part of the vest so it will blow air on the neck and will enhance goosebumps sensation.

We placed 8 vibration motor to simulate the bass sensation when the music is being played.
The vest design
We had three iterations of the vest, implementing rapid prototyping techniques.

Iteration no.1: a vest with trash bags
Iteration no.2: a vest with cloth
Iteration no.3: a vest with TPU, nylon, and fabric
