Projects for Visually Challenged
Liquid Level Identifier
A compact product named liquid level identifier which helps the visually impaired people to know the liquid level while pouring into a cup. Many products are available in the market and those are expensive. Everybody cannot afford to buy them. This is a cost effective liquid level identifier which is affordable.
This is very useful for visually challenged people to identify the level of the liquid in the glass when they are filling the glass with the liquid. It consists of two levels, one level indicates half full and second level indicates the end level. When the liquid reaches the first level it gives a long buzz, when it reaches the top it gives a continuous buzz, indicating that the glass is full of liquid.

CURRENCY COLOR IDENTIFIER
Now a days, in this materialistic world, money became the most important thing to common man. The daily life of man starts and ends with money. People can identify denomination by seeing the currency notes but in the case of visually challenged people one of the major problems is identifying the ‘denomination of currency’. So, it would be beneficial for them if they have a device with them to identify the Indian currency note denomination. The device should give the output through voice so that they can easily hear the value of currency. This device Color Identifier for Currency (CICC)’ serves this purpose. It consists of a color sensor to identify the color of paper, an array of LEDs and Light Dependent Resistors to extract the dimensions of note, a micro controller and an audio sub-system that announces the denomination.

BRAILLE MATH TRAINER
Braille Math Trainer is a smart device that can be used by visually challenged people for learning arithmetic calculations on a calculator. It can also be used to train the visually challenged to learn mathematical tables on their own. The numeric keypad in the ordinary calculators is replaced by a Braille keypad to make the visually challenged children identify and use the numbers easily. A voice output is given out in their own regional language, for the inputs given and the output obtained from the calculator. An embedded microcontroller performs all the arithmetic operations and controls the Braille keypad. A text to speech engine gives voice output. An audio amplifier is used to enhance the strength of the audio signals from text to speech converter.

‘Third Eye for Elderly and Visually Challenged Persons’ to seek out their belongings.
Fruit Identifier is a training device which helps the visually challenged people to learn the names of the objects like fruits. The Fruit Identifier helps the trainers of the blind students as they can show the shape of the fruit and give the name of the fruit by audio output.

GEOMETRIC SHAPE IDENTIFIER
The Geometrical Shape Identifier is a training device specially developed for visually challenged children to identify different geometrical shapes like circle, triangle, cube, sphere, etc. This Geometrical Shape Identifier is also useful for mentally challenged children also. The Geometric Shape Identifier is useful for both mentally challenged and visually challenged children. But the way they learn geometrical shapes using this Geometric Shape Identifier differs. The mentally challenged child select one of the geometrical shapes observes it and presses it. The system announces the name of the geometrical shape. By repeating the process many times the children can identify geometrical shapes. The visually challenged child feels a selected geometrical shape, feels it and presses it. The system announces the name of the geometric shape. By repeating this process many times the visually challenged children can identify geometrical shape

The visually challenged and elderly persons find it very difficult to identify the names of the medicines along with their usage. They always depend on their attendants for this purpose. Furthermore, it is very important for them to remember their daily dosage of medicine and take right medicine at right time. The choice of medicines is very confusing for them and in India; most of the elderly people depend on color, size and shape of the drug for their identification, which may mislead them and they make take a wrong medicine which is dangerous to their lives. So, there is a need for a system that helps the blind and elderly people in taking the right medicine at right time without depending on any one. This project aims at developing an intelligent system that provides audio messages of the names and purpose of the medicines. Also, it will be equipped with an alarm system that would alert the user as soon as it is the time for them to take medicines

RFID BASED NAVIGATION SYSTEM
The project “RFID Based Navigation System for the Visually Challenged” considers the problem of the visually challenged to identify a location and to navigate from one place to another, thereby enabling them to lead a normal life without assistance from others. In this navigation system, we are using RFID technology. With the combination of RFID transponder tags and reader, required locations are identified. The transponder tag ID is processed by Basic Stamp Microcontroller and a corresponding pre-recorded voice message is played by the voice recording and play-back IC

The biggest problem faced by the visually challenged people is to find their path from a given source to a destination by avoiding all the obstacles in their path way. However, some of the young visually challenged people does not like to be recognized as visually challenged persons .This project “Smart Belt” is a helping aid for the visually challenged to detect the obstacles along their path, without using a stick in hand so that they can disguise their disabilities.
