The next frontier in mobile computing: Your skin, biology, and the brain in the body
Have you ever considered your skin?
1858 1865
Consider the skin as a material…
Consider the skin as a material…
Self-repairing
Consider the skin as a material…
Smart membranes
Consider the skin as a material…
Quick drying
What your skin is really made of…
What your skin is really made of…
The nervous system to feel…
And so how you know…
Soft touches
Your body in space
Body positioning
Pain
Healing pain
Healing pain
Healing pain
Temperatures
The autonomic nervous system
The brain in the body
Touches every inch of skin to regulate how we feel and survive
Directly affects every
organ including the heart and lungs,
digestion and fertility
Computing the brain in the body
Challenges to Body Computing: ! 1: Body locations vary in data quality ! 2: Comfort and fit dictate if computers are worn ! 3: Weather conditions change quickly ! 4: Motion artifacts affect the skin interface ! 5: Sampling frequency drives data analytics ! 6: The meaning of data requires sensor fusion
! Toward understanding what the data means for overall health and performance
Challenge #1: Body locations vary In data quality for what’s measured
Challenge #1: Body locations vary
Challenge #1: Body locations vary
Hairy and Glabrous skin
Depth of nerves vasculature, and glands
Challenge #1: Body locations vary
Challenge #2: Comfort and fit Determine whether computers will be worn
Challenge #2: Comfort and fit
Comfort affects data quality
Challenge #2: Comfort and fit We’ve seen wrists vary 1 cm in one hour
Dictate what we look like
#2: Comfort and fit
Challenge #2: Comfort and fit
Tailored to fit
Challenge #3: Weather Conditions Change quickly across and within days
Challenge #3: Weather Patterns
Humidity
Temperature
Challenge #3: Weather Patterns
Humidity and temperature
Rain versus dry spells
As from inside to outside or outside to inside
Clothing
Clothing
Challenge #3: Weather Patterns
Humidity and temperature
Rain versus dry spells
As from inside to outside or outside to inside
Clothing
Less clothing
Challenge #3: Weather Patterns
Humidity and temperature
Rain versus dry spells
As from inside to outside or outside to inside
Clothing
Clothing
Inside versus Outside
Challenge #4: Motion artifacts From the skin interface and the resulting data
Where to put sensors
Consider degrees and g-forces
And the absence thereof
Challenge #2: Comfort and fit
Even for small movements
Challenge #5: Sampling Frequency Determines which data drives the analytics
EEG at 1000+ Hz
Motion at 20 Hz
Skin conductance at 10 Hz
Steps at 3 Hz
Heart rate at 2 Hz
Cortisol at 1/1000 Hz
Challenge #6: The meaning of data Requires sensor fusion across data streams
Challenge #6: The meaning of data Requires sensor fusion across data streams
Not all data is created equal
Do steps help to lose weight?
Are you getting good sleep?
How much is too much stress?
How places affect us
When to best manage stress
The effects of multimedia
Computing the brain in the body
Challenges to Body Computing: ! 1: Body locations vary in data quality ! 2: Comfort and fit dictate if computers are worn ! 3: Weather conditions change quickly ! 4: Motion artifacts affect the skin interface ! 5: Sampling frequency drives data analytics ! 6: The meaning of data requires sensor fusion
! Toward understanding what the data means for overall health and performance
When does health turn
into disease?
The skin = Your body and brain
! The skin doesn’t just make us look good, it directly impacts how we feel every day
! Our skin carries continuous, measurable data
about the state of our body and brain
! Body technologies need to directly address the new challenges to find meaning from the many data streams for overall health
