Smart glove

Recently more & more hearing impaired people started using sign language. There are about 70 million people in the whole World that are not able to speak (dumb). A dumb person makes communication with other people using their motion of the hand or expressions. . Sign language helps the dumb people to make communication like normal people. The sign language translator which has been already developed uses a glove fitted with sensors that can interpret the 16 English letters in American Sign Language (ASL). Accelerometers and flex sensors are used in this system which increases its overall cost. We proposed a solution as a prototype called as “smart glove-for speech impaired people” which will translate sign language into text. It will help dump and deaf people to express their thoughts in more convenient way. As a sign language we have used traditional finger movements with contact switch wrapped around the user’s fingers. An IR transmitter receiver pair, HT12E and HT12D IC and, Arduino (Micro Controller) board helps transmitting data to PC. Moreover, use of contact switches reduces the system’s overall cost.

Keywords: - Arduino, HT12E IC & HT12D IC, IR transmitter receiver, contact switch.

Smart glove

  1. 1. By:- Sapna Patil SANDIP POLYTECHNIC,NASHIK DEPARTMENT OF COMPUTER ENGINEERING PROJECT PRESENTATION ON ‘Smart glove - for speech impaired’
  2. 2. INDEX  Introduction  Existing system  Proposed system  Scope of the project  Data flow diagram  materials  Advantages  Limitations  Future work  Conclusion
  3. 3. INTRODUCTION What is Sign Language ?? Communicating language used primarily by deaf people. Uses different medium such as hands, face, or eyes rather than vocal tract or ears for communication purpose. Sign language is used by deaf & dumb people. Smart glove will be used to translate sign language into text. In sign language signs are used to communicate. Our system is aimed at maximum recognition of gesture without any training. This makes the system usable at public places where there is no room for long training sessions. Communication using sign language
  4. 4. REASON BEHIND MAKING THIS SOFTWARE..?  There are similar types of gadget which already exist but there are various drawbacks in them.  The glove which we are going to develop will translate sign language to facilitate conversation between speech and hearing impaired people and those are not conversant with sign language.
  5. 5. EXISTING SYSTEM ●Since beginning in 2003, the Microsoft Imagine Cup has tasked students the world over with developing technology aimed at solving real-world problems. ●Students were asked to build their project around a specific Millennium Development Goal (MDG). ●However, with sign language varying greatly around the world, the users can teach the system new gestures and modify existing ones.
  6. 6. PROPOSED SYSTEM  The sign language translator that we are going to developed uses a glove fitted with sensors that can interpret the 16 English letters in Indian Sign Language.  The glove uses IR transmitter receiver, RF transmitter, Encoder Decoder IC three dimensions to gather data on each finger’s position and the hand’s motion to differentiate the letters.
  7. 7. SCOPE OF THE PROJECT  Speechless people will be able to communicate with normal people.  Speechless people will be able to communicate with Speechless people as well as deaf people.  Safety is one of the highest priorities for this translator. The translator is carefully to not expose the user to any current from the circuit.

  14. 14.  HARDWARE REQUIREMENT:  512MB RAM  40 GB Hard Disk  IR transmitter receiver  Encode Decoder IC  Contact Switches  LED  Single Stand Wire  Arduino Board  SOFTWARE REQUIREMENT  Visual Studio 2005 / 08 / 10  VB.net framework 2.0 & above  Operating System: XP service 2 and above  IMPLEMENTATION REQUIREMENTS :  Monitor  Glove  EXTERNAL REQUIREMENTS :  Battery
  15. 15. ADVANTAGES  It requires fewer components so its cost is low.  Small in size: Due to small size we can place its hardware on our hand easily.  Light weight.  Flexible to users.  Easy to operate: Anyone can operate it easily.  Real time translation.
  16. 16. LIMITATION Range up to 100m only. Facial expressions are not considered.
  17. 17. FUTURE WORK This project did not focus on facial expressions although it is well known that facial expressions convey important part of sign-languages. This system can be implemented in many application areas examples include accessing government websites whereby no video clip for deaf and mute is available or filling out forms online whereby no interpreter may be present to help.
  18. 18. CONCLUSION This technology could mean a new way for about 70 million people with hearing and speech impairment to verbally communicate and connect to people around them. This project aims to lower the communication gap between the deaf or mute community and the normal world.
