Introduction And Objective
Finding a misplaced object is a tough task for
everyone and it is still tougher for blind or visually
impaired people who have little knowledge
about their surroundings.
Enabling Blind/visually impaired people to get
easy access to their frequently misplaced/lost
objects.

Previous work
Stick n find---Recently developed
mobile based application
Fetch ---- A research paper published in late 90s
It was the first in this Area

Motivation
Our project is inspired by the previous two works.
And we also received valuable inputs from a blind person whom we
interviewed at the beginning of the project.
Minutes of the Interview:
1) Mobile app better than separate device.
2) very frequently gets annoyed, if he cant find objects( 5 to 6 times a
day)
3) And he would feel comfortable if the device have an audio input
and talk back facility.

Difference? What is the need to implement something similar!!
Previous works did not target blind people i.e their application was
suited for general public but not blind/visually impaired.
We made use of swipe functions , to make it more user friendly for
them.

Tag functioning
Any query from mobile app is received by Bluetooth module and
then sent to micro-controller.
Microcontroller processes the query and activates the buzzer
accordingly.
Until the tag is searched for, it stays in the standby mode.

RFDUINO
Found a microcontroller that has an inbuilt
Bluetooth module and which is very small.
The RFduino has a Nordic 32 bit ARM Cortex-M0
processor. It still runs the same, simple Arduino
code the UNO runs also run on the RFduino.
It has a wireless module incorporating Nordic’s
nRF51822 SoC.
