Augmented dinner

  1. 1. Augmented Dinner Steve Bottelbergs Mathias Raets Pieter Vanderlinden
  2. 2. What?• Original idea: Augmented Cook – Not very useful• New idea: Augmented Dinner – Augmented reality application – Motivate children to eat healthy food – Important: kids shouldn’t notice that they are being pushed into eating vegetables
  3. 3. How?• Augmented Dinner – Make children eat vegetables by making it fun! – Introducing an augmented reality game – Starring our superhero: Metaioman!
  4. 4. How?• Detect food on a plate – Parent’s responsibility to make it healthy – How to detect the plate: • Two methods: - Image Processing (blob detection) - Markers – How to detect the food: • Blob detection
  5. 5. Image Processing• Need a division between the food• Calculate the longest uninterrupted line in the image to find the centre of the plate• Use center and radius of the plate to search for blobs• Problems: – Food cannot be placed arbitrarily – Heavy influence of environmental lighting
  6. 6. Image Processing
  7. 7. Markers• Place markers left/right of the plate• Estimate center and radius of the plate by using the markers• Problems: – Finding decent markers – Plate should be placed exactly between markers (placemat)• Advantages: – No white space on plate needed – Less influence of lighting
  8. 8. Markers
  9. 9. Blob Detection• How we improved blob detection – Averaging – Compensate hand occlusions – Normalization of the averaged Image
  10. 10. Augmented Reality• Using MetaioSDK• Biggest issue: finding decent markers – Should be stable on most conditions (lighting, reflections, …)• Initial idea: – Project game on edge of plate – Problems: • Game objects detected as blobs • Positioning of game objects • Objects deformed by slope of edges • Occlusions when eating
  11. 11. Augmented Reality• Solution: – Project game above plate
  12. 12. Game• Goal: create a fun game that children WANT to play• Appealing to children: – Superhero – Sounds – Animations – Humor
  13. 13. Setup
  14. 14. Questions?
