slide-6
SLIDE 6

Control your game

without

keyboard or mouse

Instead: using movement, special objects

  • r other visual techniques

WebCam based games are unique, because you can:

slide-7
SLIDE 7

DEMO

Replacing traditional input devices

  • Click on flying object
  • Buttons-like interactive areas
  • Scrollbars-like interactive areas
slide-8
SLIDE 8

DEMO

Results of interaction

  • Draw on top of camera view
  • Manipulate WebCam output
  • Change external visualisation

Based on computer vision library

OpenCV

SLIDE 12 ./CvGames debug

DEMO

Debugging camera data

  • Analysing current frame
  • Comparing 2 frames
  • Comparing history of input data
slide-13
SLIDE 13

Precision and noise

It is all about the light

  • Recognising color/shape vs changes
  • Low light, white balance, shadows

Webcam not mainstream

  • Fun to learn OpenCV via games but...
  • Versus: Kinect, wii, PS move
  • Responsive in all environments
slide-17
SLIDE 17

Controlled environment

  • Example: Advertise in a conference
  • Close to light source, solid background
  • Visuals/games specific to the audience
slide-18
SLIDE 18

It is still the game

  • Make it fun: scores, challenges, levels...
  • Guide the player: intro video, reminders
  • Balance: Usable vs unique
slide-19
SLIDE 19

WHAT HOW WHEN

WebCam as motion input device OpenCV for retrieval and analysis of each frame Own the light, keep it fun, use as advertisement
