Process

Throughout the development of this project, we underwent multiple iterations and refined our approach to improving the final outcome. How the project worked was that we created a grid with four UWB(Ultrawide Band) chips placed in the corner of the room and send signals to the handheld chip. The handheld chip will send the location data to the Arduino Nano according to its position in the grid. The motor and the eye in the P5 controlled by the Arduino Nano will move according to the received location data. Our process can be broken down into three key parts.

I. Stay There: Phone

The first part involved the production of the 'cell phone' device. We first laser-cut and 3D-printed the phone shell and installed the UWB receiver chip for positioning in the phone. However, during the exhibition, we encountered issues with the UWB signal reception which resulted in us having to repeatedly disassemble the phone and reset the chip to reconnect the signal. Despite this setback, we resolved the issue and ensured the device functioned as intended.

Additionally, we designed our screen cover to have a message saying "Welcome Home! The connection between the mobile device and the smart home server has failed, " indicating that the phone shouldn't be communicating with anything in the room. However, the phone is actually communicating with our 'smart home'. By this, we want to let audiences feel a sense of being unsecured but being told that they are safe.
