Learn About Wearables and Java

Do you want to learn more about wearable tech? At the next OTN Virtual Technology Summit, Java Evangelist Gerrit Grunwald shows you what you can do with wearable tech and Java. What’s a wearable?  A miniature electronic device worn under, with or on top of clothing. What are the requirements? A small size, smart power management, and connectivity. Its use is limited only by your imagination. What do you want to measure? Location? Temperature? Heart rate? Java Heartrate code

Currently, it is hard to combine wearable products, because there is no single standard. At the moment, you can only buy specialized systems such as motion trackers and GPS watches. But why not use existing cheap technology to build your own wearable Java-powered device? Using Java allows you to use your existing skills, build infrastructure, and testing tools. 

Grunwald's project uses an Odroid-W board in combination with a heart rate sensor, a GPS sensor and a BMP180 to track the heart rate and location of a runner. The battery-powered device measures the data and publishes it via MQTT to different clients such as Java(FX)-based desktop clients and a smartwatch the runner can wear. Attend this session and get some ideas of what you can do with Java and wearable devices, and learn why Java is great for this space. 

Virtual Technology Summits (VTS) are interactive, online events, sponsored by the Oracle Technology Network (OTN). VTSs are free, but you must register:

Americas - February 11th - 9am to 12:30pm PT  REGISTER

EMEA – 25 February  - 9:00 to 13:00 BST  REGISTER

APAC – 4 March  –  9:30 to 13:30 IST  REGISTER

Each OTN VTS features four technical tracks, each with a unique focus on specific tools, technologies, and tips: Java, Database, Middleware and Systems. Registration allows you to attend any session on any track. We'll kick off the VTS with Java Community Update by Tori Wieldt. There will be places to hang out and meet other attendees between sessions. Please join us!

Software Development in Turkey

What technologies are hot in Turkey? How do you get more women to speak at conferences. Turkish Project Manager Nilay Yener discusses GDG Fest Istanbul and GDG Fest Women. She describes the strategies she used to get more women to attend and speak at GDG Fest Woman. Leran more at GDG DevFestW

We're always adding more videos to the YouTube/Java channel.

IoT: Wearables!

Wearables are a subset of the Internet of Things that has gained a lot of attention. Wearables can monitor your infant's heartrate, open your front door, or warn you when someone's trying to hack your enterprise network. From Devoxx UK to Oracle OpenWorld to Devoxx4kids, everyone seems to be doing something with wearables. 

In this video, John McLear introduces the NFC Ring. It can be used to unlock doors, mobile phones, transfer information and link people. The software for developers is open source, so get coding!

If you are coming to JavaOne or Oracle OpenWorld, join us for Dress Code 2.0, a wearables meetup. Put on your best wearables gear and come hang out with the Oracle Applications User Experience team and friends at the OTN Lounge. We'll discuss the finer points of use cases, APIs, integrations, UX design, and fashion and style considerations for wearable tech development. There will be gifts for attendees sporting wearable tech, while supplies last.

What: Dress Code 2.0: A Wearables Meetup

When: Tuesday, 30-September-2014, 4-6 PM

Where: OTN Lounge at Oracle OpenWorld
