We perceive in different ways

· User-sensitive · Empathic · Universal

Something in common: Brain & Senses

Function + Pleasure + Dignity + Esteem + Aesthetics


Assumptions

Audience who: · Misses information and entertainment · Tends to lack motivation · Technology improves inclusion reality · Universal objects decrease frustration · Growing wellness market provides more leisure choices

Project aims

Conceptualization of a device that Universally supports a leisure activity

Emoti-Chair

(Full-body vibrator reacts to frequency of notes)

Ryerson University’s Centre for Learning Technologies,Toronto (Media artists, musicians, computer scientists, psychologists and human-computer interaction specialists) · Melody, bass and volume through touch-based and visual experiences


“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


How to reach a larger surface?


Closure mechanism exploration


Final shape

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


Styles


Use Textured buttons, tactile recognition of functions Vibration intensity
