IEEE PROJECTS BASED ON EMBEDDED SYSTEMS-HAND HESTURE SPEECH RECOGNITION/HAND HESTURE HOME AUTOMATION

HandTalk: Assistive Technology for the DUMB

(AMERICAN SIGN LANGUAGE)

Summary:One of the many areas in which embedded systems show great promise is assistive technologies, which address the special needs of those with impairments. This article presents HandTalk, a "smart glove" that can recognize basic hand gestures and convert them into speech using low-cost, commercial off-the-shelf (COTS) components. A low-cost, portable gesture-to-speech glove prototype demonstrates that embedded systems don't have to be expensive to be effective.

HandTalk: Assistive Technology for the Dumb

Technology has always been of great help to the disabled and given them a helping hand to allow them to live a normal and healthy life like others. we have come up with a novel idea of a glove named Handtalk that will convert hand movements into text and allow the deaf to express themselves better.

The Handtalk glove needs to be worn on the hand by the deaf or mute person and depending on the variation of movement, the device will convert it intelligently into text and display it on a nearby computer for the other person to comprehend it easily.

The Handtalk glove senses the movements through the flex sensors pads which detect the different patterns of motion and the way the finger curls. The device can sense carefully each resistance and each movement made by the hand. Currently the device can convert only few words, but depending on the success of this device few more additional words may be added later onto this expressive system.

The Gestures can be converted to voice by using a text to voice convertor softwares in the computer.

The heart of the system will be the PIC Microcontroller which is responsible for converting the hand movement signals to the corresponding codes which is further converted into text by the computer.  

Flexible Bend Sensors

The Flex Sensor is a unique component that changes resistance when bent. An un flexed sensor has a nominal resistance of 10,000 ohms (10 K). As the flex sensor is bent the resistance gradually increases. When the sensor is bent at 90 degrees its resistance will range between 30-40 K ohms.

The flex sensor may be bent greater that 360 degrees depending upon the radius of the curve. Operating temperature is -45F to 125F.

The sensor measures 1/4 inch wide, 4 1/2 inches long and only .019 inches thick!
