Thumbs down to my idea? :(

I had an idea about accelerometers in my mind for a long time which was about determining the position by double integrating the acceleration.

This idea came too many times when I had to walk from my college to PGI chowk to get my bus. I used to think that we can fit an accelerometer in one of our shoes & as we walk it keeps on telling a uC instantaneous acceleration which can be doubly integrated either by hardware of software to find the position. this would be dead reckoning. Yeah I know that there's gonna be a lot of inaccuracy involved in this...

Today I was browsing the analog's website when I saw this on their website: Accelerometers Fantasy and Reality This doc provides some concepts which are classified on the basis of their realizability. "My" concept was also listed there... and haaaa, it was on the dreamland list of concepts. :(

Too bad for me especially when I have got an accelerometer from somewhere... Now I'm gonna scrap this concept & start thinking of something new with this tiny MEMS miracle...

By the way, the accelerometer I got is square shaped & has got a number 22290 engraved on it, with a symbol of analog on it (op-amp in a box). Searched too much on Internet but I cant find its damn datasheet! There are datasheets for its lookalike accelerometers like AD22286, but no luck for me till now...

OMG

I can't imagine more humiliation of the English language than this guy showed:
