Inspiration
First of all we would like to pay glowing tribute to the Language Movement martyrs who sacrificed their lives for the mother tongue in 1952.
What is it ?
Touchless introduces a new way of interacting with the computers by means of object tracking through webcams for Bengali character writing.
Here data is inserted for writing purpose using webcam without use of keyboard or on-screen keyboard by mouse.
Tracking Process
Capturing video using aforge .net
From the tracking environment it first detect the red colored object and mark it with a rectangle using EuclideanColorFiltering.
Getting (x , y) coordinate of the rectangle and putting pixel at that point on a white panel.
So finally we get 33*30 pixel bitmap image which is ready for neural network input.
TESTING
In this phase we will test the network by giving some patterns. We match it with every trained pattern and find out the pattern that gives highest match and lowest match also.
Limitations
Due to brightness and contrast sometimes webcam can hardly detect the expected color.
Because of the similarity of tracking environment background color and object color the writing panel gets unexpected pixels.
Future plan
Add facility for writing for both Bangla and English
Add facility to make the software capable of running without the help of keyboard and mouse.
Adding printing capabilities of written text.
