Introduction

  1. Statement of Purpose

Please provide a brief description of your project. List the goals and objectives of your project and explain why this project is useful for the problem your group want to solve or functions that make your project unique.

Although walking is a great method of transportation, there are many dangerous situations a handicapped traveller may come across in their journey. Currently, a vast majority of the blind utilize white canes to gain a sense of their surroundings – we think we can use technology to do better than the white cane. We aim to design and create a light and affordable device which uses ultrasonic sensors to aid the visually impaired in their daily travels. 

      2.  Background Research

Please provide details on the background research your group has done for your project. Explain what drives you to work on this project and/or why this project is important. Also include discussions on any similar projects your group have looked at in coming up with your project. How is your proposed project different or similar to those your group have looked at.

We will use an Arduino along with multiple ultrasonic sensors (SEN136B5B) to create a "sound map" of the surrounding environment within a radius of 4 meters. Using information from this sound map, vibrations of different intensities will be transmitted to the user giving the user ample time to respond to the situation.

Design Details

  1. Block Diagram / Flow Chart

Provide a simple block diagram of your hardware design. A block diagram is a schematic graphic that shows the interactions between different components in a hardware or software system. If appropriate, please also include a flow chart showing the steps your design needs to go through to function. The online program draw.io is a great tool to create polished block diagrams and flow charts. Likewise Microsoft's visio is also a great program to create block diagrams and flow charts.

      2.  System Overview

Provide descriptions to your block diagram and flow chart. State the purpose of each block.

Parts

  • Arduino
  • Ultrasonic Sensors (SEN136B5B)
  • Vibration Motors
  • Wires
  • Breadboard

Possible Challenges

  • finding the right amount of ultrasonic sensors to cover the determined area without cancelling each other out
  • interfacing multiple sensors and motors with the arduino

References

List all references you used in your proposal. This is important, you do not want to be blamed for plagiarism. IEEE citation format is highly recommended. You can use citethisforme.com's IEEE citation generator to painlessly generate your references in this style.

One thing I'm confused about your idea is how this project is any better than a white cane. Blind people have managed to walk around without problem for centuries now, how does your project improve the situation for blind people exactly?

We think this is a bit more versatile than a white cane. Most of the time a white cane is used to detect obstacles within 1 -  2 m directly in front of the user. This will allow the user to have a 360 degrees feed on their surroundings, and be able to respond to possible threats without having to check physically with a white cane.

Gotcha, sounds interesting. I can't wait to see the finished product!

How many sensors are you planning on using? I think it would be cool to get 5-6 and have a full 360 degree coverage like you mentioned in your comment above, especially if you can mount your project to a shirt or jacket. Project approved.

Cool idea!  I like the feature of creating a 3D map of your surroundings using multiple US sensors.
