Description
Create a Scratch block-based program using the AI “Human Body” extension in a creative and engaging way, in order to draw on a screen without the need for a traditional mouse or touchscreen.
Instructions
  • Connect to the https://ai.thestempedia.com and create a teacher & students accounts.
  • Import the extensions ‘Human Body Detection’,’ Pen’,’ Text to Speech’.
  • Add the ‘Pencil’ Sprite from the library and create 7 sprites (‘write’, ‘clear’, ‘black’, ‘red’, ‘blue’, ‘green’, ‘pink’).
  • Write commands to check what happens when the ‘pencil’ sprite touches one of the other sprites.
  • Write commands to enable the camera to recognize Hand Pose and move the pencil to the x and y coordinates of your index finger.
  • Change costume at the end of the roll.
  • Add sound effects.
