1. INTRODUCTION
With the advancements in technology, the living has also
evolved. CRT TVs have been replaced by Smart TVs. Smart
watches have taken place of regular watches. Similarly,
smart phones have taken over classic mobile phones. The
expensive 3D mirrors made in foreign countries are limited
to use in public locale only. The biggest drawback of these
mirrors is the cost required to built them and it does not
provide enough penetration rate. The degree of integration
between the home automation and smart mirrors is very
less. The insufficient relevance of functions is also one of the
main problems faced in the smart mirror. These problems
are overcome by designing a Raspberry Pi based Smart
Mirror. The Smart Mirror is based on the principles of
unidirectional mirror imaging with added technique like
speech recognition. The entire system communicates
through the Internet not only to make the system work but
also make the smart home come to life. The content is
structured as follows: Section II describes the Literature
Survey, at to how the previous models were studied, Section
III describes the components required and their
functionality. In the Section IV, the detailed explanation of
the diagrams is given. Section V describes the methods that
are used to implement the proposed system. In Section VI
the implementation diagrams along with the phases are
shown. The paper is then concluded in the Section VII.

of this model is that the device is in continuous search of
nearby Bluetooth enabled devices which consumes more
power. Users without mobile phones can’t access the smart
mirror. Implementation and Customization of a Smart Mirror
[6] in IEEE paper was proposed in November 2017 by Ivette
Cristina, Rodrigo Salmon, Rosario, Alfredo Padilla. The smart
mirror’s important features include Voice interaction, face
recognition, personalized user information. The is based on
modern filtering techniques such as collaborative filtering
and content based filtering. Languages used are CSS, HTML,
and JavaScript. The only drawback is that it uses Raspberry
Pi 3 which does not have a PoE slot for wired internet
connection. IoT based Smart Mirror using Raspberry Pi[7] in
IEEE paper was proposed in 2018 Conference proceedings of
IJERT by Lakshmi NM, MS, P, . The mirror consists of all the
basic features like display date and time, news, weather etc.
The additional feature included in this mirror is thief
detection module which is a used to capture some malicious
act in the house. To display the temperature DHT22 sensor is
connected to GPIO pins of Raspberry Pi which is not
necessary because the weather detection module has the
same concept.

5. METHODOLOGY
Our project is divided mainly into four phases. As per the
scope of work, the project is bifurcated as follows.
The power supply here is used to power on the
raspberry pi for the boot purpose.
The LCD screen for displaying the visual output.
The window wooden frame for the support.
Microphone is used for taking the voice input from
the end user(s).
Raspberry is used for all the processing required.
Ethernet cable for fast internet connectivity and for
making use of the cloud services.
Speaker for giving the output in the form of voice.
1. Designing the system.
2. Configuring the Raspberry Pi.
3. Programming the Display Screen.
4. Fabrication.
Designing the system - Dimension – Our system's first and
foremost phase was the dimension. The dimension of the
mirror was decided by the LCD screen we used in this model.
As we used an LCD screen, we need a mirror slightly bigger
than the screen and which could reflect as well as see
through.
Flowchart
Construction of the Frame – The frame was necessary to be
built to contain the electronic components as well as the
mirror. A wooden frame of just the right size was built. The
wooden frame helps keep the system steady and provides
durability to the mirror as well as protects it from physical
damage. Similarly, by hiding the electronic components
behind the frame gives it a premium finish and the
components are saved from physical contact. The material of
the Mirror – To find a bi-directional mirror was difficult in
the first attempt. Since the mirror wasn't readily available,
we ordered a custom bi-directional mirror from a local glass
hardware shop.
Configuring the Raspberry Pi - Using SD card formatter,
format the SD card. Once the SD card is formatted install the
image file for OS and then extract this zip file using 7zip
software. The next step is to download the etcher software to
make the OS by transferring the image file into the software
and directly store this file in the memory card.
Programming the Display Screen - Display of time, date,
weather, news on the mirror is using Python language. The
use of a mobile application is to provide a personalized and
customized view of the mirror. The is designed using HTML,
CSS, and JavaScript.
Fabrication - Frame - This phase involves creating the
actual apparatus to contain the mirror and its electronics.
We started off by using a compound miter saw to cut four
pieces which were then joined together with wood screws to
form a box. Next, four pieces of wooden trim (with
accompanying corner blocks) were hand-nailed to the outer
edge of the frame with 2” finishing nails. Once installed, the
trim overlapped the inner edge of our frame by 1⁄2” so as to
prevent the glass from falling forward. Bi-Directional Mirror
- Next, we needed to install our actual mirror. With the
overlapping trim mentioned above, it was a straightforward
installation, involving us easing the glass gently into the
frame itself and securing it with two wooden blocks screwed
in behind the mirror itself. The glass is now essentially

In this figure, the flowchart of the model is given, here the
basic interaction with voice is shown. Users can give
instructions to the system to view a list of commands that
are available. Then, they can give commands via voice
instructions provided. Thus, the flow chart helps to
understand the system better

sandwiched between these blocks in the rear and the
overlapped trim in the front. Components - The final step of
the fabrication phase was to install the suite of electronics
that power the mirror. First, we mounted the display
monitor by laying it against the glass and screwing in two
blocks (one on its top, the other along the bottom) to hold it
in place. Next, we used to mount the Raspberry Pi on the
glass and proceeded to hook up the necessary cabling.
Finally, we installed our power bar by using its built-in
screw mounts to secure it to the bottom piece of the frame.
Phase 2

module along with phase 1 implementation.
In phase 2 the weather module, the holidays' module and the
compliments module were also added.
Weather Module
Fig. 5.1 Screenshot of phase 1 describing news, clock &
calendar
In this phase, the only modules that were perfectly
implemented were the news and the clock modules.
The clock module used the raspberry pi's local variables i.e
the system configuration variables in order to determine the
current time and date which in turn help in the fetching of
the current news for the news module.
Fig. 5.3 Screenshot of weather module.
The news module showed the news from various parts of the
desired location, which can also be customized to be
country-specific.
The weather module also used the locale variables for
fetching the current weather. The current weather
depending on the date and time is shown.
In our case, the news was fetched from different news sites
as shown in the above screenshot

Holiday’s Module
The news module shows the current news depending on the
date and time and also it is location specific.
In addition to all these things a dynamic photo changing
module was also added in order to display dynamic pictures
after a certain interval of time.
6. CONCLUSION
The final product of this project is a framework that has
different modules, among which identify the functions of the
calendar, weather, news, alerts. The smart mirror we build in
our project implements all of the functions mentioned above.
In addition, it has features for news recommendation and
interaction by voice commands, these two features seek to
provide a more sophisticated user experience and allow a
natural interaction between the mirror and the user. Smart
Mirror saves time and makes it easier to access information.
It allows users to see relevant information effortlessly. In
future, this mirror can be improved by adding an interactive
touch screen and theft detection feature.
