2. Problem
 A large number of people in our country are visually impaired.
 Lack of technological support.
 Specially for people of lower middle class or lower class there is lack of
support.
 No smart devices are currently available in market for blind people.
 If available they are costly and not affordable for a huge number of people.
 People are afraid of complex use of technology

3. Solution
 Spark eye- our smart glass for blind people. It helps a person to walk smoothly
in streets or home . It helps them by guiding in local language. Anyone can set
the voice commands in his favorite local language and move.
 The device is easy to use and required a very little amount to produce that
anyone would love to have it.
 It works on a rechargeable battery and it takes ½ hours for full charge.
 The device guide a person to move front , to wait someone in front, to move
right, to move left etc.
 The glass looks like an ordinary glass with smart features.

4. Methodology
Some theoretical and technical methods are followed to develop
this system. First of all to design the glass a proper design was
imagined and painted which sets at someone's eyes comfortably.
Use of ultrasonic vision for obstacle detection. Ultrasonic can
detect obstacle up to a specific distance. Ultrasonic sensor we
have used here can detect up to 2 cm to 400 cm. It is programmed
in a way that it will start giving alert of obstacles between a
moderate gap from user to obstacle. Microcontroller and other
circuit elements are designed compactly so that it won’t harm the
user. For charging the battery there is a separate port. There is
3.5 mm headphone jack for user to connect his headphone with
the device.

9. Controller Design & Implementation
 We have used atmega328 IC with arduino microcontroller board. We have
used audio module for voice navigation and ultrasonic sensor for obstacle
detection.
 Power supply used 12 volt. We have connected and powered the circuit using
LED acid battery.

10. Unique Selling Point
 We have developed this product for greater benefit of humankind. We have
no motive to sell it and making profit.
 Public’s satisfaction is our profit.
 So far no such device is available in local market.
 In global market it is available with higher price.

11. Business Model
 Production Cost :
900 taka
 Marketing and promotion :
1000-2000 taka per month
 Selling Cost:
700 taka (For 100 piece production)
