This device is designed to provide with a greater advantage producing voice based announcement for the users i.e., the user gets the voice which pronounces his need as and when it is required.

“Speech” and “gestures” are the expressions, which are mostly used in communication between human beings. Learning of their use begins with the first years of life. In human communication, the use of speech and gestures is completely coordinated. Machine gesture and sign language recognition is about recognition of gestures and sign language using gloves.

A number of hardware techniques are used for gathering information about body positioning; typically either image-based (using cameras, moving lights etc.) or device-based (using instrumented gloves, position trackers etc.), although hybrids are beginning to come about. However, getting the data is only the first step. The second step, that of Recognizing the sign or gesture once it has been captured is much more challenging, especially in a Continuous stream. In fact currently, this is the focus of the research.

An embedded system is some combination of computer hardware and software, with either fixed or programmable capabilities, that is specifically designed for a particular kind of application device.

Embedded systems do a very specific task, they cannot be programmed to do different things.

Microcontrollers are widely used in embedded systems

products. Microcontroller is a programmable device.

The Intel 8052 is, single chip microcontroller (µC) which

was developed by Intel in 1980 for use in embedded

systems.

Keil software

Keil compiler is a software used where the machine language code is written and compiled. After compilation, the machine source code is converted into hex code which is to be dumped into the microcontroller for further processing. Keil compiler also supports C language code.

Automatic Controlling through Speech and Gestures

Easy to install and use.
