“I grew up in an environment of hearing people who had a relationship with sound and emotions that I never fully understand because I could not experience it first-hand,”with the emotichair it was like “feeling the emotions (of the music) dance across my skin” Ellen Hibbard, deaf from birth

Design research revelation
Empathy happened when I volunteered and served this community without having only research facts in my mind. Design for ability
Final Scope
Immerse technology that expands the sound perception through tactile feedback. Applicable to both, leisure and daily activities
Vibrates with sound Easy to use Easy to clean Waterproof Accessible Portable Fast setting up Adjustable Cost effective
Inspiration
“The organs in which animal electricity acts above all others, and by which it is distributed throughout the whole body, are the nerves, and the most important organ of secretion is the brain� Christoph Heinrich Plaff
Our brain gives meaning to all inputs
Ideation Vibsens generates vibratorial mapping, the brain receives this patterns through dermatones on the skin and ads meaning

Function
3 motors vibrate against the skin according to app input. Motors reach two different dermatomes regions (C7 and C9) Over-molded rubber protects skin allowing smooth pressure
Function Test
Vibratory mapping testing
Arduino coding: bass, melody and pitch perception
Test 1
22 mm. (0.8”)
Test 2
50 mm. (1.9”)
Test 3
8 mm. (3.14”)
3 motors on a 20 mm width bracelet allow a cleaner pattern recognition
Increased immersion
through multiple added locations
Form - size Sizes: S, M and L Necessary to ensure correct positioning of the motors 2 cm width, 1.4 cm height Size S: 20 cm length Size M: 23 cm length Size L: 26 cm length
