2. Overview About Me Why The Goals What Exists What I wanted Gestures 101 Demo
3. About Me
4. About Me Joel Lord Development Manager Javascript junkie, technology enthusiast, IoT hobbyist. Macadamian http://www.macadamian.com Twitter: @joel__lord Github: github.com/joellord
5. Stereotypes I have never fought a polar bear with my bare hands
6. Stereotypes My yard last April
7. Why ?
8. Why •  Worked with Nodebots for a while now •  Wanted to explore other possibilities of NodeJs •  Because controlling a robot with a Kinect is pretty cool
9. The Goals
10. The Goals •  Needed a way to use events to tell the robot to perform an action •  Gestures seemed the best way to achieve this
11. What currently exists
12. What current exists Basic Nodebot Stack •  NodeJs (https://nodejs.org/) •  Socket.io (http://socket.io/) •  Johnny-Five (http://johnny-five.io/)
13. What current exists node-openni •  Connects the Kinect to NodeJs using OpenNI •  Very basic event for almost everything •  No gestures !
14. What I needed
15. What I Needed •  Support for a full “skeleton” •  Support for gestures
16. What I Needed
17. Gestures 101
18. Gestures 101 The Basics •  Is the initial condition met? •  Is the condition still met? •  Is the final condition met?
19. Gestures 101 What do I need for gestures? •  A skeleton with an event when it changes •  Know the position of the COM •  Have a “base unit”
20. Gestures 101 Introducing kinect-gestures •  Gesture detection using a base class •  Tracks the skeleton for an initial condition •  Checks every 100ms to see if the condition is still met •  If the final condition is met, trigger an event •  Other classes are used to define the actual gestures
21. Robocalypse Demo Let’s look at some code !
22. Next few steps •  Return a more friendly coordinate system for skeleton •  Add more information to the returned •  Add more gestures (jump, wave, kick)
23. Questions?
