E&I PROJECTS ABSTRACT FOR INSTRUMENTATION,Assisting blind persons using gsm and gps
1. Assisting Blind Persons using GPS and
GSM
Blindness is the condition of lacking visual perception due to physiological
or neurological factors.
Various scales have been developed to describe the extent of vision loss and
define blindness. Total blindness is the complete lack of form and visual
light perception and is clinically recorded as NLP, an abbreviation for "no
light perception."[1] Blindness is frequently used to describe severe visual
impairment with residual vision. Those described as having only light
perception have no more sight than the ability to tell light from dark and the
general direction of a light source.
Many people with serious visual impairments can travel independently,
using a wide range of tools and techniques. Orientation and mobility
specialists are professionals who are specifically trained to teach people with
visual impairments how to travel safely, confidently, and independently in
the home and the community. These professionals can also help blind people
to practice travelling on specific routes which they may use often, such as
the route from one's house to a convenience store. Becoming familiar with
an environment or route can make it much easier for a blind person to
navigate successfully.
Traditional Tools such as the white cane with a red tip - the international
symbol of blindness - may also be used to improve mobility. A long cane is
used to extend the user's range of touch sensation. It is usually swung in a
2. low sweeping motion, across the intended path of travel, to detect obstacles.
However, techniques for cane travel can vary depending on the user and/or
the situation. Some visually impaired persons do not carry these kinds of
canes, opting instead for the shorter, lighter identification (ID) cane. Still
others require a support cane. The choice depends on the individual's vision,
motivation, and other factors.
Proposed Idea:
Our idea is to assist blind people using GPS and GSM mobility aid. We can
construct a embedded unit which can assist blind people by giving
intimation to the family members about the persons location periodically.
This can also be done incase of any obstacles detection.
Operation:
The user will carry a embedded unit which comprises of a obstacle
and vibration sensor. When a obstacle is detected the microcontroller gets
the present position using GPS and sends that information to a remote
mobile phone as an SMS Message.. So that the family members can know
the exact position of the blind person. The unit has an option to send this
information periodically so that, the family members can track the blind
person’s movement.

4. Power Supply
Provides +5VDC and +12VDC power supply for the IC’s and the sensors for
its proper operation
Dspi30F4013 Microcontroller
Microchip's newest dsPIC® Digital Signal Controller (DSC) and PIC24
MCUs offer the performance speed of 40 million instructions per second
(MIPS), selfprogramming capabilities via Flash memory and industrial and
extended temperature ranges. This IC severs as a CPU for the whole system.
Ultrasonic Sensor
Obstacle sensor (ultrasonic Sensors) is used to detect any obstacles in
the path converts that into electrical signal and it is connected to the dsPIC
Microcontroller.
Vibration Sensor
Vibration sensor is used to detect any Vibrations and converts that
into electrical signal and it is connected to the dsPIC Microcontroller.
GPS Receiver
ProGin SR-92 is a low-power, ultra-high performance, easy to use GPS
smart antenna module based on SiRF’s third generation single chip. Its low
power consumption and high performance enables the adoption of handheld
applications. The slim design allows SR-92 to be placed on top side of the
housing to have best GPS signal reception. The 5-pin I/O interface is then
connected to the main board with either connector or wire soldering.
GSM Mobile (Nokia 3310)
A Nokia 3310 mobile is used as a GSM modem and is used to send
SMS Messages to the remotely located Monitoring unit.
