Traces in movement
Drawing between the real and the virtual thanks to characters and objects brought to life by body movement


In this activity, students can use the movement of their character (Sprite) to leave a visible trace: the moving character leaves a trail in the virtual environment, creating a shape or an abstract drawing, depending on what you are trying to do. This activity can be a continuation of Bodies in motion between the real and the virtual, or it can be the starting point for other explorations, for example repeating or reproducing the traces you created with body movements.
This activity was developed starting from the Scratch online platform designed by LifeLong Kindergarten at MIT Media Lab (Boston) , which scintillae has been in dialogue with since it opened.

The continuous interaction and exchange created between the real and the virtual worlds emphasize an idea of the digital that is not alienating, but one which favors and supports the relationship between the child and the surrounding world. The interconnection between different fields of knowledge and school subjects becomes fundamental and generative in the creation of new knowledge and in promoting and supporting the research processes of children.

from designing to sharing
This section is a guide for adults to orient and support children’s and young people’s projects. The children’s hypotheses, starting from some initial questions, will be verified and deepened during the activity.
Questions to start with:
Can you play with movement?
What happened in the trailer you saw?
How do you think this happened in the trailer you saw?
What inspired your drawing?
How can you use the sprite trail (for example: drawing, writing or using virtual space in an unusual way)?
What happens by changing the size of the sprite?
What happens if the sprite rotates as it moves?
What changes when the movement is slower or changes in intensity?
How does the trail of the sprite change with respect to the movement perceived by the webcam?
What combinations of speed and sensitivity interested you most and why?
What difficulties did you encounter? What strategies did you use to solve them?
What happens if you move away from the computer webcam?
What happens if you use an object to move the sprites?
What is the relationship between the position of your body in real space and the position of the sprites in their virtual space?
How did the Scratch environment change your initial design?
Tip:
In this project, we use some blocks from the Scratch < Video Sensing >. These blocks activate your computer’s webcam and allow you to use motion to activate and animate sprites in Scratch.
/ in the first case (post-it), you need to “touch” the sprite to activate it, always maintaining this connection in order to guide and move it in the Scratch space.
/ in the second case (leaf), you need to “touch” the sprite to activate it, but unlike the first sprite, it will move away as soon as it perceives a movement.
