The objective of this thesis was to build a smart mirror system which would show information to the users while also reflecting their own image. For building the mirror, a monitor was used along with a Raspberry Pi system and a two-way acrylic mirror. The Raspberry Pi is connected to the monitor through an HDMI cable and the mirror is acting as a layer in front of the mirror for showing the information displayed on the monitor while reflecting the images. The software of the mirror was developed using ElectronJS, a JavaScript library for building desktop applications. As a result, the mirror was built, and the software was developed. They were assembled together to act as a real mirror.
