Speed kills! In 1830 people thought, your brain stops working travelling more than 20 mph. And anyone going at more than 30 mph would have all air sucked out of them and would suffocate to death.

Regular Users don’t Rule the Tech!

Today's Smart Home solutions are

not good enough for a mainstream

market. These solutions are well

suited to early adopters, but have so

far failed to attract mainstream

buyers. (see VisionMobile “The Smart

Home Landscape 2015”)

Use SmartHome Plug-In via SSE and REST API

• List of Things via HTTP Get http://localhost:9998/rest/things

• Server Sent Events (SSE)http://localhost:9998/rest/events

• Helps to check what’s possible and what’s going on

• Player

• Unique ID is always location

• Relevant data is separated into components (channels)

Minecraft Bindingfor Eclipse SmartHome• Integrating Devices

into Eclipse SmartHome

1. Create OSGi skeleton

2. Edit identifiers and parameters

3. Add binding logic

4. Export and deploy

5. Test

Businesses are coming to realize that attracting developers is the fastest route to innovation. Moreover, attracting developers means attracting external investment, which finances innovation and expansion.

MYTHS OF TYPICAL DEVELOPER / BORN TO CODE

Innovation Prosumer: Consumer and Producer

Millions and millions of dollars are being spent to attract developers: The millions of dollars in developer marketing efforts serve one purpose: to persuade developers to use a specific platform, network, tool or API set to generate innovations and to reach more consumers. In short: Developers consume an Platform, API, etc. and produce something based on it.

Some Consumers turn into Developers to solve their needs.
