Smart Stick for the blind

The Challenge: 

The Question: 

How can we create a device that blind people use to navigate their environment confidently?

The Solution: 

There are few products in the market and DIY solutions in the web. For now, we eleminate this idea.

Channels: 

Idea is about helping blind people about the outside world’s obsticles. Smart stick should have a simcard for navigation (GPRS) communication with friends, family and hospitals. Smart stick should have accelometre sensor to sense the obstickles in streets and roads. It should be used with earphone. It should converts envori- ments conditions to sound via APPs or API’s of google Maps. Normal people could use it too, it can be designed as 2 peaces (modular) People without disabilities can take the top part from the stick and put it in their bags (with earphones)

 

What are the main aspects of this project?

Our goal is to help the blind people. Our perspective is to find a way to eleminate the difficulties they face everyday.

 

How to?

We can
- use a eyeglasses with earphones - headsets and eye bandages
- blind smart sticks

Techonolgy out there
- infrared sensors
- Arduino + 3 ultrasound sensors+ buzzer +motor - Another chipset + RFID + ultrasound sensor

 

Project Halo:

- Rigid frame (I used a round embroidery frame)
- Female headers (for the sensors)
- Ultrasonic Rangefinders (Parallax Ping Rangefinders) - Wire (Wires with male and female leads are conve-nient)
- Glue
- Twist ties to tidy up wiring
- Soldering station
- Male headers (for creating a bridge to feed 5v and ground
- RJ-45-Term Screw Terminal (2) - RJ-45 Cable

- Marker

Motor Modules:

- Vibration Motors (5) - Motot, VIB,3V/60mA, 7500RPM

- Grid-Style PC Board
- Male header pins
- Motor "shroud" (to prevent things getting sucked into the motor)

Haptic Headband:

- Headband
- Sewing Kit
- 5 Motor Modules
- Wire (Wires with male and female leads are conve-nient)
- Safety Pins
- Female headers
- Soldering station
- RJ-45-Term Screw Terminal (2) - RJ-45 Cable
- Marker

 

Wiring the Microcontroller:

- Arduino Mega 2560

- Wire (Wires with male and female leads are conve- nient)

- 5 LEDs
- Darlington IC - ULN 2803A - 2 port screw terminal
- 9v battery
- 5v regulator

 

Building the Software:

- USB cable
- PC (for editing code and downloading to Arduino)
- Arduino
- Arduino development environment (www.arduino.cc) - Source Code, modified Ping.h library

XploR cane

The 'XploR' mobility cane was developed at Birming- ham City University
It uses a camera and built-in sensors to scan for faces in a crowd

If it recognises a face the cane vibrates and guides user with audio cues
Sensors work up to 32ft (10 metres) and faces are stored on an SD card

Is this a sort of benchmarking?

Very interesting, @wave . But there is something I do not understand: it seems you are going through similar projects done in the past and making a list of them. What's next? Do you want to modify and improve them? To make some and have visually impaired people in your own city try them?
