Transcript

1. confidential not for distribution A Full Stack 2015 Toronto presentation by Joel Lord Robocalypse: Controlling Nodebots with Kinect gestures
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. We’re hiring ! http://www.macadamian.com/careers
6. Houston… We’ve got a problem.
7. Why ?
8. Why •  Worked with Nodebots for a while now
9. Why •  Worked with Nodebots for a while now •  Wanted to explore other possibilities of NodeJs
10. 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
11. The Goals
12. The Goals •  Needed a way to use events to tell the robot to perform an action •  Gestures seemed the best way to achieve this
13. The Goals •  Needed a way to use events to tell the robot to perform an action •  Gestures seemed the best way to achieve this
14. What currently exists
15. What current exists Basic Nodebot Stack •  NodeJs (https://nodejs.org/)
16. What current exists Basic Nodebot Stack •  NodeJs (https://nodejs.org/) •  Socket.io (http://socket.io/)
17. What current exists Basic Nodebot Stack •  NodeJs (https://nodejs.org/) •  Socket.io (http://socket.io/) •  Johnny-Five (http://johnny-five.io/)
18. What current exists node-openni •  Connects the Kinect to NodeJs using OpenNI
19. What current exists node-openni •  Connects the Kinect to NodeJs using OpenNI •  Very basic event for almost everything
20. What current exists node-openni •  Connects the Kinect to NodeJs using OpenNI •  Very basic event for almost everything •  No gestures !
21. What I needed
22. What I Needed •  Support for gestures
23. What I Needed •  Support for gestures •  Support for a full “skeleton”
24. Gestures 101
25. Gestures 101 The Basics •  Is the initial condition met?
26. Gestures 101 The Basics •  Is the initial condition met? •  Is the condition still met?
27. Gestures 101 The Basics •  Is the initial condition met? •  Is the condition still met? •  Is the final condition met?
28. Gestures 101 What do I need for gestures? •  A skeleton with an event when it changes
29. Gestures 101 What do I need for gestures? •  A skeleton with an event when it changes •  Know the position of the COM
30. 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”
31. Gestures 101 Introducing kinect-gestures •  Gesture detection using a base class
32. Gestures 101 Introducing kinect-gestures •  Gesture detection using a base class •  Tracks the skeleton for an initial condition
33. 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
34. 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
35. 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
36. Robocalypse Demo Let’s look at some code !
37. Next few steps •  Return a more friendly coordinate system for skeleton •  Add more information to the returned •  Add more gestures (jump, wave, kick)
38. Questions?
