hi friends,this is my first post.
i'm going to do my final year project based on eye movement analysis using matlab.
i need interface a hardware material holding up laser with the matlab software and it should move also based on my head movements. can you give any suggestions for me to start and finish it well...

 

So you want to aim a laser based on a person's eye position? (As opposed to using a laser to determine eye position, which sounds dangerous.)

 

How are you determining eye movement?

Where will laser be mounted?

Head movement could be determined by accelerometer.

 

Head movement could be determined by accelerometer.

I don't think that's entirely true. An accelerometer can't determine rotation in the horizontal plane (yaw, on an airplane). Motion, yes, but not absolute position. I think.

But anyway I think the OP wants to follow only the eye position, not the head position. Hard to tell.

 

In his first post he states "and also based on my head movements". Hence, the accelerometer should detect movement. I agree it wouldn't detect absolute position but relative position could be tracked in software.

 

our eye movement is observed by placing a camera near our eye and processing work may be done using image acquition toolbox of matlab

 

I can't help with any of that, except to help define the needs.

Are you planning to hold the head fixed, so that the camera can be fixed on the pupil? If the camera must track the eyes as they move with the head, that will be a very complex assembly. Perhaps a facial recognition app can determine head position, but then you would still need to determine eye position.

And the laser; will it be mounted on a tripod or such, with 2 axes of movement? That should be a relatively easy aspect of the project.

 

I suspect the OP is woefully unprepared for such a project.

 

Perhaps not eye movement, but helmet, or other head gear device can be servo'd to the laser position drivers. Then a 'bulls eye' sighting marking can be used by the wearer to position the helmet on the object that needs to be blasted by laser light.

 

Take a gander at the "Eyewriter" project. It has a website: http://www.eyewriter.org/ and many DIY references as well http://lmgtfy.com/?q=eyewriter. I was trying to get a feel from the OP as to where he was headed and his skill level.

Head or eyes?

Are you sure you have clear idea of what you intend to design?

The rest of us certainly are not.
Happy New Year!

take a look at these... i was planned something like this...

 

okay friends,i'm intend to my final year project in wireless or matlab based processing along with embedded...can anyone suggest me any ideas...please...

 

Do you believe that your proposed project meets the requirements? If your teacher is aware of that linked project, will you get credit for reverse engineering what was already done there? I think it would be a challenging project if you start with nothing, but it will be far easier (too easy?) to copy that existing project.

 

ya i'm really interested to start with nothing as you said... so only i'm searching for new ideas..pealse guide me
