OVERVIEW

WHAT IS ULTRACANE WORKING SWITCHING AND RANGE SELECTION FEATURES OF ULTRACANE ADVANTAGES LIMITATIONS

INTRODUCTION

Ultra cane was invented by three professors

Professor Deborah Whittington Dr Dean Waters Professor Brian HoyleThere are about 12 million visually impaired

or blind people in this world

WHAT IS ULTRACANE

An intelligent tool for blind with AI techniques

The Ultracane is a new electronic mobility aid for visually-impaired people

The ultra cane used to be known as the “Bat cane”

because bats navigate in total darkness using “echolation”.

PRINCIPLE

Ultrasonic sensors transmit ultrasonic waves from its sensor head and again receives the ultrasonic waves reflected from an object.

By measuring the length of time from the transmission to reception of the sonic wave, it detects the position of the object

WORKING

UltraCane consists of a special handle containing an ultrasound radar system to detect objects and obstacles

The handle features a hand-grip with two yellow feedback buttons on the upper surface

UltraCane is switched on, the two buttons

will vibrate as obstacles are detected.

The button nearest the front of the handle will vibrate when obstacles are detected by the sensor facing forwards

button nearest the back of the handle will vibrate when obstacles are detected by the sensor facing upwards. The vibration rate of the buttons increases as you move closer to obstacles.

Brain works at a subconscious level and accepts information from the three main senses - sight, hearing and touch.

For someone with vision impairment, the brain has two sources of information available to it: hearing and touch.

So they can building up a spatial map and becoming aware of your surroundings and any dangers

Working with brain

SWITCHING AND

RANGE SELECTION

The switch has three positions: Off, On (for short range) On (for long range)

overheadsensordetects objects approximately 1.5 metres or 5 feet from the handle of the caneFor two ranges it will be same

forwardsensorThe forward sensor covers two ranges

It will detect obstacles within approximately 4 metres / 13 feet in the forward direction

For Long Range

I forwardsensor t will detect obstacles within approximately 2.1 metres / 7 feet in the forward direction

For Short Range

Features

It is suitable for both left and right handed peopleIt is a good cane technique with the cane hand centred with the wrist as the primary pivot point.

The sensors will then face correctly upwards and forwards

they feel objects in their environment through the cane's vibrations

ADVANTAGES

carbon graphite collapsible cane is reflective and lightweight

easy to use, just switch it on and go works on two rechargeable AA batteries,

so its running costs are low Switchable between “near” or “far”

settings, so the Ultra Cane can detect objects 2m or 4m away to suit the environment you are in.

LIMITATIONS

The UltraCane will not detect objects within 30 cm / 12 inches of the sensors.

It is not possible for the UltraCane to detect drops in ground level

Heavy rain will stop your UltraCane from working properly and should be avoided.

CONCLUSION

It’s a revolution towards the blindness Very few people are aware of this cane

and the real pride comes when every blind person is benefited from this.

The main idea behind this paper is to contribute our service to the blind society and helping them with the little knowledge that we have.
