Android Wear and the Future of Smartwatch
- 1. Android Wear and the Future of Smartwatch koan-sin tan freedom@computer.org COSCUP, July 19, 2014, Taipei
- 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 • “Out of Their Minds”, http:// cs.nyu.edu/shasha/ outofmind.html, http:// www.amazon.com/Out-their- Minds-Discoveries-Scientists/ dp/0387982698
- 17. How to read this Doraemon watch
- 18. a time stopper • Do you call this a watch?
- 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 http://www.samsung.com/us/globalinnovation/innovation_areas/#digital-health http://www.pcmag.com/article2/0,2817,2458663,00.asp
- 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
- 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
- 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
- 32. we are often limited by current form factors Cover of Byte Apr, 1981 issue
- 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
- 34. –Douglas Adams "so amazingly primitive that they still think digital watches are a pretty neat idea.”
- 35. backup slide
- 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
