Sad Box
In Future City, due to the flexible and transformative nature of the space, areas are in close contact with each other, which sometimes can become problematic when using a single space for different activities. That is, when adjacent to the workplace of the laboratory where the focus is needed, other team members form a meeting, keeping in mind the loudness of the meeting becomes crucial. The Future City Lab team designed and implemented the “Sad Box” to solve this problem. This box helps (
) the meeting members to keep their volume at optimum levels so as not to disturb other activities.
How does Sad Box work?
Sad box has a sound sensor. When the volume goes above the expectation’s limit, it expresses its sadness.
There is a microcontroller inside the sad box that adjusts the timing of the sound sensor and the light.
