3 Part I, OS of Everything in IoT

4 Internet of Things Part I. OS of Everything in IoT Internet uses Things Internet Things use Internet??? 4

5 Internet of Things Part I. OS of Everything in IoT Q) Why do you want to use Internet? A) If I know when my master is coming, I can make room temperature more comfortable for my master. It will make my master happier. 5

6 Internet of Things Part I. OS of Everything in IoT Q) How do you know when he is coming? A) It depends. My master is usually coming home by his car. I may guess his arrival time, if I know when he is parking his car at home. 6

7 Internet of Things Part I. OS of Everything in IoT Q) If your master goes out after parking,... A) In the estimated time, if my master isn t coming home, I will send message to him. Air-conditioner: I started to make room temperature." He can stop me or let me know his arrival by replying message. Master: I will be home at 4:00pm." 7

8 Internet of Things Part I. OS of Everything in IoT The more utilizations of Internet, the smarter services by IoT devices Things use Internet 8

9 What s needed in the things? Part I. OS of Everything in IoT Open platform, allowing to add new IoT service app which provides more personalized service and make the device much smarter Application framework / API Service App IoT Open Platform Utilize the information from Internet of Things Provide smart service and add more value to device - Personalized service - Context-aware service Internet 9

10 Another way? Part I. OS of Everything in IoT Device provides only the pre-defined interface to the connected. Service app is running on the other device or cloud which can provide the more personalized service. Device App Service App [w/o AppFW] Provide the pre-defined interface HUB IoT Open Platform Internet 10
