The development part was split to 2 parts.

Our part was to design the whole exhibition space, interface and the functionality behind the surface to make sure all the in coming data were visualized perfectly. The other part taken part by JNOME was to develop the hardware and software to collect all data from 50 different devices, store it to cloud, and send send it back to the local machine which operates the UI, which also required developing 16 raspberry pi modules to analyze the location of each device.

Each sensor kept sending data every 1 second. Sensors were connected to the gateway via Bluetooth, to upload data over network. Software designed using vvvv had access to the network, to receive fresh data uploaded on the server. We located 16 gateways and 20/50 sensors all over the map to constantly collect data of the certain room. Other 30/50 sensors were worn by volunteers to visualize real-time data. Gateway had a function to identify the nearest gateway of each sensor. We used this function to visualize how people move from one possition to the other.
