Creating Augmented Reality Apps with RubyMotion

Augmented Reality (AR) is the new cool. But did you know you could write AR apps (and games!) using Ruby(Motion, that is)? Come and escape normal boring reality with us, as we create a native AR app using RubyMotion.

3. Why RubyMotion?
4. Why RubyMotion? Because it’s Ruby, duh.
5. But it’s mobile *native* development, so why not use…
10. Why Not…
11. Why Not… • I’ve used it
12. Why Not… • I’ve used it • Syntax is ugly and hard to read
13. Why Not… • I’ve used it • Syntax is ugly and hard to read • It’s the old, uncool language
14. Why Not…
15. Why Not… • Language has been evolving *very* fast
16. Why Not… • Language has been evolving *very* fast • Every new version (5 so far) breaks backward compatibility
17. Why Not… • Language has been evolving *very* fast • Every new version (5 so far) breaks backward compatibility • although last release was better
18. Why Not… • Language has been evolving *very* fast • Every new version (5 so far) breaks backward compatibility • although last release was better • 5 years they’ve managed to raise the language to a level of complexity that rivals the much older Java
19. Why Not… • Language has been evolving *very* fast • Every new version (5 so far) breaks backward compatibility • although last release was better • 5 years they’ve managed to raise the language to a level of complexity that rivals the much older Java • That’s not a compliment
20. Why Not… • Language has been evolving *very* fast • Every new version (5 so far) breaks backward compatibility • although last release was better • 5 years they’ve managed to raise the language to a level of complexity that rivals the much older Java • That’s not a compliment • I will say the syntax is nicer than ObjC
21. Why Not…
22. Why Not… • I’m sorry
23. Why Not… • I’m sorry • No, I’m not that sorry
24. Why Not… • I’m sorry • No, I’m not that sorry • I really hate Javascript
25. Why Not… • I’m sorry • No, I’m not that sorry • I really hate Javascript • And it’s not really native, so there’s that
26. Why Not… • I’m sorry • No, I’m not that sorry • I really hate Javascript • And it’s not really native, so there’s that • Besides, every mobile app you really hate was probably created with Javascript

34. Why did I chose RubyMotion? WIMBY Wells In My Back Yard wimby.ca
35. Tried Objective C
36. Tried Objective C Still disliked it
37. Tried Objective C Still disliked it Context Switch was brutal

40. Difficult
41. Difficult ‣ Lack of *good*, *deep* examples
42. Difficult ‣ Lack of *good*, *deep* examples ‣ Constant need to translate from Objective C
43. Difficult ‣ Lack of *good*, *deep* examples ‣ Constant need to translate from Objective C ‣ And now from Swift examples to figure stuff out

45. Why not teach?
46. I love teaching, but..
47. I love teaching, but.. Live teaching is exhausting
48. What about online? And WNDX School was born

50. But the AR, Lori… Where’s the Augmented Reality we were promised?
51. New cool APIs like ARKit Apple WWDC
55. Need to create new AR examples!
56. Start Somewhere
57. Augmented Reality Hello World
58. LIVE CODING ALERT
59. LIVE CODING ALERT
60. Augmented Reality Hello World
61. Other tutorials like Ray Wenderlich
62. Places Of Interest
63. POI Code

65. If you don’t find this example compelling
66. If you don’t find this example compelling • Make it your own.
67. If you don’t find this example compelling • Make it your own. • Don’t need to use Google data or get a Google API key
68. If you don’t find this example compelling • Make it your own. • Don’t need to use Google data or get a Google API key
69. If you don’t find this example compelling • Make it your own. • Don’t need to use Google data or get a Google API key • Check your local government (civic, state, or federal) Open Data.
70. If you don’t find this example compelling • Make it your own. • Don’t need to use Google data or get a Google API key • Check your local government (civic, state, or federal) Open Data. • Download some data with precise GPS locations, and go crazy
71. How about a real example?
73. How about a game?
74. How about a game?

83. But there’s a twist to this story
84. I lied
85. Not me
86. Well sort of
87. Well sort of I helped
88. My Intern built these apps
89. First year Comp Sci
90. First year Comp Sci • Derek
91. First year Comp Sci • Derek • Done a little web programming
92. First year Comp Sci • Derek • Done a little web programming • Learned Java in 1st year
93. How does a first year student do this?
94. 1. Learn Ruby
95. 2. Choose Your Own Adventure
96. 2. Choose Your Own Adventure He chose ARKit And a game
97. 3. Reviewed all the MiM videos
98. I did help
99. Amir helped, too
100. So why tell you all that.
101. Not enough diverse apps out there
102. More diverse app creators needed
103. More diverse app creators needed • To see the problems others don’t see
104. More diverse app creators needed • To see the problems others don’t see • To create the apps to solve those problems
105. WNDX School is here to help you To help you, Ruby Developers, get those app ideas out of your heads and into the App Store.
106. So do me a favour, and get out there and build YOUR app!
107. So do me a favour, and get out there and build YOUR app! Or help someone build an app to solve THEIR problem.
