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.

Speech is the best means of communication between two people but speech disabled people cannot express their views to others which irritates and disappoints them. In order to serve their basic needs, a device called “Talking Box” is designed as a helping hand. Talking Box is a device that provides effective method of communication for the speech disabled. In this, the basic needs of a person are pre recorded in the switches present on the device. So by pressing the switches the person can convey his needs to other people. An IC APR9600 is employed for this purpose. The basic function of IC is to pre record the message and playback. A speech disabled person tries hard to convey his message in sign language. In order to understand his feelings the other person must know the language. From this a system has been developed that would help him in conveying his message. This project includes the proposed solution and its working. This system is implemented by using simple hardware called “Talking Box”.

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.

The main objective of this project is to guide the visually challenged. In this project digital compass is used for direction sensing and GPS for location identification. Obstacle sensing is obtained by using long range ultrasonic distance sensor and human identification is done by using PIR sensor, for voice output APR9600 is used. All these components are interfaced to PIC microcontroller. Visually impaired people are many in number and they encounter a lot of problems in doing their routine work. The major problems of the visually challenged are identifying obstacles and location information. There are several E-Sticks available for the visually challenged, but those can detect the obstacle only, which is not a complete solution for the basic problems of the visually challenged. To overcome the disadvantages of the E-Stick, this Smart Jacket has been developed which includes features such as guiding the persons in their desired direction and location identification through voice output, detection of humans through buzzer and detection of obstacles through a vibrator.
Obstacle/human detection and voice navigation for visually challenged
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.

Independent mobility is crucial for development of physical, cognitive, communicative and social skill for physically impaired people and the elderly people. Thus the electric powered wheel chairs are more popular in such circumstances. The Project “Versatile Wheel Chair” enables both the physically impaired and elderly people to move independently. The multiple means of control of Wheel Chair are more flexible to use in any conditions and can be controlled according to the user. The versatile wheel chair can be controlled by three devices, Joystick, IR sensors and Tilt sensors. The user can use the joystick to control the wheel chair. Joystick can be moved by applying a very little amount of force, by means of hands. So the elderly who are unable to move the Wheel Chair manually, can easily control the Wheel chair by a means of Joystick. In some cases, the physically challenged and the elderly people may not have sufficient strength to control the Wheel Chair by means of Joystick. In such cases the Tilt sensors are used in order to move the Wheel Chair. In this case there is no necessity of applying force, by moving the head to certain angle the wheel chair can be controlled. As there is no need of joy stick while moving in regularly used places, a pair of IR sensors are used to move the wheel chair along a pre-defined path.

Visually challenged children do not have visual access to the world. More often this is done through verbal descriptions and presentation of tactile models and graphics. The project “Learning Aids for the Visually Challenged” incorporates a tactile graphic system to identify the shape of a structure. While maps of continents and countries, city maps and building layouts are the most obvious uses for tactile graphics, the educational potential hidden in raised lines and textures goes far beyond such displays. Geometric figures, cross sections of single cells and of whole living organisms, machines, graphs and diagrams of everyday objects, plants and animals etc can be made accessible to the blind students through these tactile graphic learning aids. However, there are limitations to tactile images because they need excessive labelling and it may be difficult for the hands to locate and relate all the features of the image. So, there is a need for putting an audio signal together with the tactile image. So, audio messages are juxtaposed with the tactile graphics in this project to teach the blind children

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

Lot of research is going on to study the behaviour and to increase the learning abilities of mentally challenged children. Depending on the way the mentally challenged children learn things, they are categorized into groups such as visual learners, auditory learners, reading /writing preference learners, kinaesthetic learners. This paper integrates all the learning abilities of mentally challenged children and proposed a new scheme to make them learn alphabets and numbers. This method provides both entertainment and exercise for their brains. The proposed device consists of a reference 7×5 LED matrix displays, a touch screen to write, and audio system. An alphabet or number will be displayed on the reference LED matrix display by observing which the child tries to write the shape on touch screen display. If the child writes correct shape then the system gives an applause, if not it says “Try again”, so the child try to do it repeatedly until he/she gets an applause. This system increases the concentration levels and co- ordination of the child.

According to census 2001, it is estimated that over 21 million people in India are suffering from one or the other kind of disability. This is equivalent to 2.1% of the total population. Of all the disabilities, the mentally challenged children are nearly 10.3%. This is quite a huge percentage. The Snoezelen therapy is now effectively being used for the development of the mentally challenged. The mentally challenged children cannot communicate with others comfortably. They may get into depression when they are alone and often feel disturbed and cannot come out of this state by themselves. One way to get them out of their depression is to provide them some entertainment in the form of music or by providing some colours appear in front of them.
This project “VOICE ACTIVATED SNOEZELEN BUBBLE TUBE (VASBT)” is useful for the mentally challenged children. The bubble tube also provides multisensory stimulation and provides soothing to the people who are suffering from dementia. The Snoezelen therapy is now being used for curing the people suffering from autism and other developmental disorders such as dementia and brain injuries. In voice activated Snoezelen bubble tube, the led’s will dance according to the music
and also produce colour spectrum. This concept is being used in many fields such as schools, hospitals and in many places. Ultimately the voice activated Snoezelen bubble tube will be useful and provides entertainment to every person. The voice activated Snoezelen bubble tube will be a very useful product and as this is developed taking economic factors into consideration, it is cost effective and is affordable to everyone

‘Third Eye for Elderly and Visually Challenged Persons’ to seek out their belongings.
Many mentally challenged people grow physically but they cannot perform many simple actions like walking as normal individuals do. This is because the neural cells in the brain of such people are not developed as in the case of normal human beings. So their legs are weak and they cannot move their legs even to stand on their feet. So training is required to make them walk on their own. The training process is painful and boring for them so they show reluctance in taking training. The most challenging aspect in designing “GAIT TRAINING SYSTEM” for the mentally challenged people is to motivate them to walk by playing music. This inspires them to take a move without any support or motivation.
