Finger Art Grace Li, Sean Liu Project Checkoff Checklist Gesture Detection – Sean Video Capture Module • Output color from camera • Create filter module over video frame to identify brush end points • Display camera output as a video mode (if time permits) Center of Mass Module • Calculate overall center of mass of brush • Calculate two centers of mass of brush • Display center of mass on screen (if time permits) • Average centers of mass over last 8 calculations Velocity Module • Create circular buffer for last 32 centers of mass • Update total distance between points Intention Module • Create a color palette • Identify if user is absorbing paint or placing paint • Use button to detect when user is putting brush to canvas • Use circular motion to detect when user is putting brush to canvas (if time permits) • Use flashing LED to detect if user wants to put brush to canvas (if time permits) Game Module (if time permits) • Paint Paint Revolution – system outputs a paint pattern and user has to attempt to paint pattern (if time permits)Paint Genesis – Grace Saturation Module • Create internal counter • Output +/- 1 sel_saturation Color Generator • Store current color (15 bits) and saturation (3 bits) • Modify color based on new saturation values • Additional bits for saturation (if time permits) Brush Generator • Create simple brush blobs • Create complex brush blobs (if time permits) • Create additional brush types based on velocity (if time permits) • Calculate three equidistant points between centers of mass Painter Module • Read ZBT for current color and saturation • Create new pixel color • Write new pixel color to ZBT ZBT • Store 18-bits per pixel – 15 bits of color, 3 bits of saturation • Be able to alternate between reading and writing at 80 MHz • Read 5 pixels ahead • Additional bits for saturation (if time permits) Display Module • Generate 800x600 display signals • Fetch color at 40 MHz • Show position of brush ends Game Module (if time permits) • Paint Paint Revolution – system outputs a paint pattern and user has to attempt to paint pattern (if time
