Gesture-based Distribution Modrator Tool

This tool allows the user to use a touch screen device and finger gestures to dynamically create or modify a 3D probabiliy distribution.

Input/Output

Input Parameters:

  • (Optional) Width, height, and matrix representing overall probability distribution map

Output Parameters:

  • Mastrix representing newly created or modified probability distribution map

Functions to be implemented

  • Create test application with OpenTK (OpenGL for C#).
  • Interface components:
    • Interface to specify width and height for new probability distribution map.
    • Networking component to communicate to central repository.
    • Button to contact central repository to load current probability distribution map.
    • Button to save distribution map to central repository.
    • Interface to load probability distribution map from a file.
    • Interface to save probability distribution map to a file.
    • Button to view probability distribution in 3D (read-only).
  • Implement generating 3D surface based on probability distribution map.
  • Implement colormap on 3D surface.
  • (Optional) Overlay terrain map on top of probability distribution map.
  • Implement 2D navigation gestures (two-finger gestures)
    • Zoom in (two fingers going opposite directions moving away from each other)
    • Zoom out (two fingers going opposite directions moving closer to each other)
    • Pan (two fingers going the same directions in parellal)
  • Implement 3D navigation gestures (two-finger gestures)
    • Rotate left (one finger fixed, other finger moving circularly counter-clockwise)
    • Rotate right (one finger fixed, other finger moving circularly clockwise)
    • Rotate up (one finger fixed, other finger moving toward first finger vertically)
    • Rotate down (one finger fixed, other finger moving away from first finger vertically)
  • Implement 2D modification gestures (one-finger gestures)
    • Raise hill (clockwise circular motion)
    • Flatten hill (counter-clockwise circular motion)
    • Delete (cross)
    • Un-do (straight down)
    • Re-do (straight up)
  • Gesture Recognition:
    • First detect one-finger or two-finger gesture.
    • Certain gestures only work with certain views.
    • 2D navigation gestures just compute and classify.
    • 3D navigation gestures just compute and classify.
    • 2D modification gestures use k-nn to learn
      • Build training interface
      • Raise hill add Gaussian distribution. First circle defines Gaussian shape (3 standard deviation)
      • Flatten hill substract Gaussian distribution. First circle defines Gaussian shape (3 standard deviation)
      • Delete, first stroke in the cross defines bounding box.

Current To Do List

  • Play with sample touch screen test app
  • Code up gesture recognition (training and classification)
  • Code up a quick prototype DistMod GUI (with openGL)
