The document introduces the Generic Open Terminal API (gotapi) and Web-Device API, which provides a framework for accessing web-based device APIs via smartphones, supporting various apps and devices. It emphasizes the role of gotapi in enabling communication between web applications and external devices, ensuring security and management functions. Additionally, it outlines use cases in automotive and healthcare sectors, illustrating the potential for creating an open ecosystem through incremental plugin additions.

- 2. Ø Framework to access Web based Device APIs with Smartphones (OS- independent, Proven to work on Android and iOS) Ø Device APIs support Web, native, and hybrid Apps ü With Web-Device API, one will have access (using standard browsers) to external device data Ø GotAPI Source Code: ü NTT DOCOMO contributed GotAPI project as “Device Connect”, October 2014 https://github.com/DeviceConnect/DeviceConnect ü It is already capable of supporting various devices (See the URL for the supported devices) ü Latest specification link: GotAPI & Web-Device API Introduction http://technical.openmobilealliance.org/Technical/technical-information/release-program/current-releases/generic-open-terminal- api-framework-1-0
- 3. GotAPI – Device API with Smartphone (Purpose) Camera Smart Light Glasses Internet Web Apps/URL Browser GotAPI Device APIs Device APIs : Plug-Ins IEEE 11073 (Data Format Standard) Ø GotAPI provides a common adaptation layer between the devices and the applications that consolidates all common functions like security, authorization and management policies for all plug-ins Ø GotAPI passes the end device(s) data to Browser and Web-based Applications. Ø Acts as a bridge between Web APPs and Device APIs Ø Provides access control to Device APIs (Devices) Ø Device APIs expose data to web applications The Device APIs are the mediators between the GotAPI and external devices
- 4. Ø Head-Unit takes on the same function as a Smartphone, connecting Device APIs (Plug-ins) through GotAPI to Web applications Ø Head-Unit will now communicate with end devices such as: ü tire pressure sensor, brakes, Oxygen level reader, and OBD Web Apps/URL Browser GotAPI Extension Plug-In Extension Plug-In Extension Plug-In Device APIs Oxygen level reader Extension Plug-In BrakesTire Pressure Device APIs: Internet On-Board Diagnostics (OBD) GotAPI-Device APIs with Automotive Head Unit
- 5. Ø Host Device (Smartphone) will act as a companion to the External Device Ø One typical use case is to provide an in-vehicle infotainment (IVI) in a Head-Unit with functionalities and contents in driver’s Smartphone. Host Device: Smartphone (e.g. in driver’s pocket) External Device: Head Unit/In-Vehicle Infotainment (IVI) Request Response Web App Remote API Content Files Driver’s profile etc. Navigation Web App with Driver’s Personalization GotAPI Simplified Flows Interaction between Smartphone and Head-Unit
- 6. GotAPI & Device API – Heart Rate Monitor (Example) 1. Heart Rate Monitor (HRM) pairs with its Device API through Bluetooth 2. App/User request to access the HRM is received by the GotAPI Auth Server 3. GotAPI Auth Server authorizes access to the HRM 4. App/User requests the reading of the heart rate from the HRM 5. The heart rate reading is relayed by the Device API through the GotAPI Server to the App/User HRM GotAPI Server Device API/ Plug-In App/User Bluetooth GotAPI Auth Server 1 4 2 3 5
- 7. Ø GotAPI provides a common adaptation layer between the devices and the applications that consolidates all common functions like security, authorization and management policies for all plug-ins Ø With GotAPI & Device API we can create an open and independent eco-system for any vertical application ü We can incrementally build our Device API portfolio by adding plug- ins on top of the GotAPI framework Ø Some use cases of GotAPI and Device API include: ü Linking Internet with In-Vehicle environment for Automotive Telematics ü Linking healthcare devices with web-based applications/services Summary

Web technology Plug-Ins External devices • GotAPI Server loosely couples apps and Plug-ins (i.e., external devices) • Adding new Plug-Ins extends the features and ext. devices • Plug-Ins can be freely provided by device vendors & 3rd parties any time via app markets • Apps to access services provided by Plug-Ins using web technologies, e.g., HTTP REST, JSON, etc. • Standardized APIs and proprietary APIs can be freely implemented in Plug-Ins. • Enabling apps running in browsers to access external devices consistently across any OS • Currently no way for web programmers to develop apps for external devices Help the APP Developer • to deal with fragmented technologies and lack of open standards • to manage different vendors and device customization Flexible architecture Cross platform technology Abstract the complexity for App Developers GotAPI/Device API solution Smartphone GotAPI/Device Solution Advantages
