SeeMe is a collaborative physical-digital tree, positioned in an elementary school classroom, that helps pupils at 4th to 6th grade reflect the emotional experiences they are experiencing in the virtual space, by expressing them in the physical world through colors and sounds. The students report about positive and empowering experiences or negative and offensive experiences through a dedicated app, on the time after school. The data is being sent to the tree in the classroom which processes the ratio of experiences reported in the previous day, so that positive experiences are expressed as green lights and negative experiences are expressed as red lights.
When the students arrive to class in the morning, they can press a button on the bottom of the tree that updates and displays the lights on the tree according to the reports ratio. In addition the students can get closer to the tree to hear sentences that are relevant to the class situation in the virtual space as reflected on the tree. SeeMe encourages dialogue among the children, and between the children and the teacher about the feelings and emotions that arise as a result of using the network, in order to help affected children deal with the vulnerability they experienced using dialogue and sharing.
How does it work?
The technology is based on ESP8266 microcontroller, which operates a speaker and an individually addressable LED strip so that each LED bulb is colored and flashes according to the type of report it reflects. In order to be update, the microcontroller sends an HTTP request to a web server in the cloud, which retrieves and processes all new reports relevant to the specific class from a MongoDB database (using authentication), and returns as a response an index of the sound file to be played and a color array according to the number of LEDs in the controller. A web application developed in React detects and allows children to report from their phones to a web server in the cloud using an appropriate HTTP request.
