SDKs
❖ Android Wear & Apple Watch:
❖ SDK released
❖ Full applications
❖ Microsoft Band:
❖ SDK Preview
❖ Only pushing notifications
❖ Reading sensor data

12.
Design choices
❖ Avoid prompting to use phone
❖ Avoid keyboard input
❖ Short battery life
❖ Sensors (capturing – passive/active)
❖ Small screen of device (wearable)
❖ Different interactions (voice, one tab, …)

Lessons Learned

32.
Wearables challenges
❖ Wearables are costly (as you need a smartphone)
❖ minimum 300 USD combines purchase
❖ New technology (SDK new and still evolving)
❖ When no internet, low battery, …
❖ Privacy, Security and Compliance challenges

33.
Interesting to combine with APEX
❖ REST Webservices
❖ JSON in the database
❖ Native code language of smartphone / wearable
