13. ANCSとAndroid Wear

14. ANCSって何？
Apple Notification Center Service (ANCS)
ANCSの目的は、BLEを通してiOSと接続されたアクセサリに、iOS
で発生する様々なNotificationを通知する仕組み
ANCSのデザイン3原則
- Simplicity(簡潔的)
- Efficiency(効率的)
- Scalability(スケーラビリティ)

15. Android Wearって何？
Small, powerful devices, worn on the body. Useful information when you
need it most. Intelligent answers to spoken questions. Tools to help reach
fitness goals. Your key to a multiscreen world.
- 体に装着した、小さくパワフルなデバイス群。
- あなたがより情報を必要とする時の便利な情報。
- 音声での質問にこたえるインテリジェントな応答。
- フィットネスの成功を手助けするツール。
- マルチスクリーンワールドへのキー。
