Arduino board

The Arduino is an open source platform

It is made up of a microcontroller and an IDE (Integrated Development Environment)

Introduced in 2005

Can be programmed

Used to create electronic platforms

Product Applications

Flying

Track• Pilots

breathing + Heart rate

• Pressure + Oxygen in the cockpit

Current Systems Colour Detecting ArduinoExamples

Uses and RGB LED to Detect Colours

Colour detector is help up against the coloured screens

Displays values

Made from an Arduino, an RGB LED, a resistor and photocell

This colour sensor works by placing different colour cards on top of three coloured LED’s

The matching LED lights up for example if a red card is placed over the LED’s, only the red LED will light up

Made from LED’s phototransistors, resistors and an Arduino

Current systems

Product Challenges

How the blind person will interact with the device

Finding it to use it

How to put the device on charge

These are all challenges we will address through ideation sketches and research into new technology

Systems already in place tohelp the blind when crossing▶ Textured Floor ▶ Spinning Toggle

Not all crossings have a green and red man so the sensor will need to be long

distance

TechnologyParts Required

Wave shield for sound output

▶ Is a modular circuit board that sits on top of the Arduino board

▶ It can play up to 22KHz, 12bit uncompressed audio files of any length

▶ It's low cost

▶ has an on-board DAC, filter and op-amp for high quality output

▶ Volume can be controlled using a thumbwheel potentiometer

Colour sensor for detecting colours

▶ R,G,B data is in true 8-bit RGB format

▶ RGB colour data and lx can be output simultaneously

▶ Three different output modes

▶ Wide operating temperature range

▶ Simple instruction set consisting of only 5 commands

▶ Reading time: 620ms (milliseconds) Vibration Motor

▶ Indicates the wearer when a status has changed

▶ Moving parts are protected within housing

▶ Has a 2 - 3.6V operating range

Justifications / reasons

Interesting and Challenging

One in five people aged 75 and over are living with sight loss.

One in two people aged 90 and over are living with sight loss.

Nearly two-thirds of people living with sight loss are women.

Adults with learning disabilities are 10 times more likely to be blind or partially sighted than the general population.

Initial Idea The system is physically

contained within a wristband - looks similar to a watch

When the user places his/her wrist in front of the crossing screen it will detect when the green man appears and then vibrate (Output)

Can make a noise (Output) when the colour is detected

Another idea was to integrate the colour sensor with a “blind pole/cane” and make a built in Arduino system within the cane

Bracelet Ideas

Possible watch stylization

Discreet

Comfortable
