Activity summary
In this activity, we used the "Sound Canvas" experiment, which is a simple drawing tool that works through both sight and sound. In the first half of the session, each student was provided with an iPad with the experiment running on it. Students had about 10-15 minutes to try the app and make drawings with their fingertips. In the second half of the session, students were invited to use the Promethean board and try drawing on the large screen.
Goals
Observe and compare the interactions between the small screen devices e.g. tablets and large screen devices e.g. Promethean Board
Observe students response to audio feedback
Learn more about visual and 2D interactions that are accompanied by a sound
Notes from the session
Teachers had to use activate "Guided Access" on the iPads to block certain areas on the interface and prevent students from accidentally touching different controls or links
Adding sound as a supporting stimulus seemed helpful in most cases
More than one teacher asked if we could change colors or sounds which wasn’t possible with Sound Canvas
Some students wanted to use their wrists or entire hands to interact, not just fingers, which we weren’t able to accommodate
Students weren’t able to use both hands at the same time
Most students were able to maintain contact with the touch surface long enough to emulate drag and drop function
We observed one student who remained engaged regardless of whether the sound was on or off. We didn’t try this with most of the students.
One of the teachers suggested adding light to this demo to make it more engaging for students
Notes for C2LC design
Option to turn the sound on/off is very important
Option to change the color of the lines
Option to change the thickness of the lines by pressure
Option for multiple pointers, so individual students can use both hands or multiple students could collaborate at the same time.
Option to quickly save and export images
Option to insert images so students can draw on top of the images and educators can use this as a tracing activity
Option to zoom in/out of canvas
