2. who am i
• a open source user, learnt to use Unix on VAX
11/780 running 4.3BSD
• did several weird works: recently example,
figuring out how iPhone 5s DVFS and thermal
management work
• involved a bit in Android stuff at the company I
am working for
3. Outline
• Introduction to Android Wear
• What know about smartwatch/bands and other
things such as iOS HealthKit
• What can we anticipate in near feature
4. Android Wear
• Android’s extension for wearable computing, currently,
specifically for smart watches
• possible merge with Google Glass
• possible unified notifications with other Android new
extensions (TV and Auto)
• Android Wear Developer Preview in March, 2014
• Formally introduced in the keynote of Google I/O 2014
• a session named “Android Wear: The developer's perspective”
in Google I/O 2014
7. Current Android Wear
• Current SDK after Google I/O
• voice enabled, wearable apps, data exchanging and synchronization
• It’s kinda disappointed
• peripheral/auxiliary to your Android phone
• there are some inspiring bands/smartwatches already
• NO HealthKit like framework available (yet), Google Fit is not there (yet)
• to me, a guy watched Science Ninja Team Gatchaman (科學⼩小飛俠/科學
忍者隊), that’s kinda lack of imagination
• Hopefully, future Android Wear releases will be much better
10. Some bands and smart
watch
• Bands: Nike+ FuelBand, Jawbone UP24, and
FitBit Force
• Smartwatches: Pebble Steel, Omate TrueSmart,
Casio Sports Gear STB-1000, Meta Watch
11. “Bird go” (バード‧ゴー, ⽕火⿃鳥功)
Gesture and voice command could enable transform/
change
12. –Alan C. Kay
“The best way to predict the future is to
invent it”
http://en.wikipedia.org/wiki/Alan_Kay
13. digital watch and sci-fi
• 2001: A Space Odyssey
• Arthur C. Clarke, Stanley Kubrick
• inspirations of many AI and other researches
• “In 1970, the first digital wristwatch with an LED display
was mass-produced. Called the Pulsar, and produced
by the Hamilton Watch Company, this watch was hinted
at two years prior when the same company created a
prototype digital watch for Kubrick's 2001: A Space
Odyssey.” http://en.wikipedia.org/wiki/Digital_clock
14. Isaac Asimov’s world fair article
• there is a world fair in
1964 (50 years ago)
• Isaac Asimov wrote
an article for the New
York Times. He
predicted what the
world world be now in
50 years
15. • If you interested in knowing
more about sci-fi and
computer/computer scientist,
this book is a good starting
point

20. Samsung Simband
• Simband sensors
• PPG: photo sensing
• green and red light at difference wavelength
• pulse, blood concentration: e.g., blood oxygen
levels
• bio-impedance
• heart rate, blood flow, respiration,
• Galvanic Skin Response (GSR)
• body temperature
• ECG
• two parts and a loop
• measure the rate and regularity of a wear’s
heart beats
• PPG+ECG: blood pressure
• And more common ones, e.g., gyroscope

21. iOS 8 HearthKit
• no complete public documentation is available yet
• What available are WWDC slide decks
• Introduction to Health Kit
• Accessories
• accessories with built-in HealthKit support
• Heart rate monitor, glucose sensor, blood
pressure monitor, health thermometer
22.
23. Health Kit: a framework
• A framework to enable sharing between health & apps
• what are health and fitness apps?
• Statistical Analysis (Graphs, Trends)
• Enter Information
• Application from Health Providers
• what does HealthKit to
• creating data
• saving data
• querying/retrieving data
24. • Unit conversion
• HKUnit and HKQuantity
• Data: HKObjectType & HKObject
• Saving & Query:
• HKStoreStore, HKQuery
29. What are done automatically
• Get information from built-in sensors
• Pedometer (step counter) data -
> distance
• activity recognition
• connecting with some BLE devices
• Heart rate monitor
• glucose sensor
• blood pressure monitor
• health thermometer
30.
31. Connecting wearable with
Android/iOS devices
• Android Wear
• Android 4.3/Google Play Services/Bluetooth, for now
• HealthKit
• not limited
• built-in Bluetooth Low Energy (BLE) support for certain devices
• BLE+GATT
• ExternalAccessory framework, CoreBluetooth, USB, and Wi-Fi
can be used if appropriate
33. Wearable
• should not be limited to watches and glasses
• in the Science Ninja Team Gatchaman, e.g.,
special clothes
• in case you don’t know, clothes (hey, that’s
wearable) are also a topic with long history and
extensive literature
• you know more and more hardware is getting
more intelligent because of software
36. Q&A of the Google I/O
Android Wear talk
• Or say, why some people are excited enough
• Google Play Services: 4.3 or later
• 30 seconds timeout on home screen
• gyroscope or other sensors on wearable, collect on the wearable and send to your phone
• switch between app: use voice
• your voice commands see documentation
• voice time series, record memo. CODEC problem. stream the bytes to the phones.
• directly connect to internet? NO full http stack on the wearable (yet)
• no speaker on the two devices
• voice commands are not the same with Google Glass's
• AOSP, open source part? AOSP --> AOSP, Google Play Service <--- proprietary
