the internet and get news feeds. The temperature interfaced on the circuit is used to display temperature and
display it on the mirror fitted display. Thus we demonstrate a futuristic IOT smart mirror with news and
temperature display.

26. Speaking System for Mute People Using Hand Gestures
It is very difficult for mute people to convey their message to regular people. Since regular people are not
trained on hand sign language, the communication becomes very difficult. In emergency or other times when
a mute person travelling or among new people communication with nearby people or conveying a message
becomes very difficult. Here we propose a smart speaking system that help mute people in conveying their
message to regular people using hand motions and gestures. The system makes use of a hand motion reading
system equipped with motion and flex sensors along with a speaker unit. This system is powered by a battery
powered circuitry to run it. A raspberry pi is used for processing the data and operating the system. The
system consists of around 10 stored messages like “need help”, “where is the toilet/washroom” and so on that
help mute people convey basic messages. The system reads persons hand motions for different variations of
hand movement. It also consists of a trigger sensor in order to indate that the person wishes to activate the
system and speak something. This ensures the system does not speak when the person is just involuntarily
making hand motions. The raspberry pi processor constantly receives input sensor values and then processes
it. Now it searches for matching messages for the set of sensor values. Once it is found in memory this
messages is retrieved and is spoken out using text to speech processing through the interfaced speaker. Thus
we have a fully functional smart speaking system to help mute people communicate with regular people using
a simple wearable system.

27. Smart E Glasses for Voltage Measurement
Here we propose smart glasses for electrical works for easy voltage measurement while working. Usually
while testing/troubleshooting electrical works/PCB the person faces issues while placing probes on 2 points
and looking at the multimeter at the exact time. This consumes a lot of time as well leads to faulty/improper
measurements. To solve this issue we propose to integrate voltage display through the user’s glasses for a
virtual voltage display while troubleshooting/ testing the system. We use a raspberry pi based circuit for
processing and displaying output. The glass frame is made using a smartly constructed miniature frame. The
frame is constructed to fit a mini display along with circuitry and the display lens used for desired reflection
on the glass frame. The system is fabricated so as to fit easily on a person’s ears and enable the person to view
the circuitry along with voltage measured. The circuit consists of a voltage measurement circuit that is
integrated to the glass in order to get the voltage inputs to the raspberry pi display. Thus we have an efficient
voltage measurement display using raspberry pi.
