how many sensors?
let’s sum them up...
2 microphones2 camerasaccelerometergyroscopecompassproximityambient lightpressurebattery temperature
= TOT 11
...plus the software based sensors!
orientationstep countertilt ……= 26 listed in official doc*
*actually lot more defined by manufacturers
what are sensors for?
microphone: call
accelerometer: orientation
proximity: turn off the screen
…
repurposing!
microphone: call >>> Shazam, send messages without any connectivity, ...
accelerometer: orientation >>> gaming, step, tilt, user activity, ...
proximity: turn off the screen >>> air gesture recognition, ...
“Exaptation: A character previously shaped by natural selection for a particular function, is coopted for a new use”Gould & Vrba 1982
a little digression: exaptation
heart tracking
“A smartphone may be able to measure your heart and breathing rates, even if you’re not directly touching it”
MIT’s Media Lab 2015

problem? device fragmentation
● android operating system
● screen size
● CPU & GPU
● sensor prevalence and performances
several kinds of fragmentation
sensor prevalences
sensor performances
● battery consumption
● sampling rate
● accuracy
● wake-up / non-wake-up
● batching mode
WhatsApp uses proximity sensor when playing a voice message, in order to decide if play message with loud speaker or ear-speaker.
simple and yet...the solution does not work well on all Android devices! (no selection pressure)
case study: whatsapp & proximity sensor
Material design: visual design and interaction fragmentation
Android Compatibility programme: compatibilities issues
next future...Chip manufacturing: hardware fragmentation
efforts to solve fragmentation

everyone should give it a look!

test your device here:
loads of tech in our hands.loads of potentials.but what about interactions?how do all these interfaces impact to human behavior?who leads the conversation?
interfaces as transparent as none
creates safe - natural - multimodaluser experiences
