    Gulam got a reaction from dpharris in Project f-Spell: Now you can type even without Keyboard!   
    It all started with an aim of improving communication between speech & hearing impaired and normal people. But it has now almost become an alternative input device for any computing device!
     
    So what is it all about? It's a cyber glove that recognizes sign language gestures and convert them into ASCII. Voila! We can throw away our keyboards and start using this glove. Right? After all, our keyboard does the same thing.
     
    Don't try too hard to visualize this peculiar device! This is how it will be!!
     

    And Technically it will be something like this
     
    And more technically the flow of data will be like this

     
     
    Got a overall picture? Okay. Let's see how this is implemented. The sensor boards which are mounted on the finger tips is a custom PCB (see attachements schema_acc_board.png & pcb_footprint_acc_board.pdf) which houses the accelerometer (in our case MMA7361L). Those accelerometers will be connected MSP430 Launchpad and Launchpad will then be connected to Bluetooth Module as shown below. (BT boosterpack from iTeadStudio is used here)
     

     
    Wondering why not all axes of accelerometers are utilized? Well we have to do some trade-off between resolution and no. of ADC channels available :-( 
     
    That's all. Find the code as attachment (code.zip)
     
    Here are few pics of the setup & output...
     
     
     



     
    Attempts have been made to miniaturize the whole setup into one glove. The FET Debugger is not able to recognize the custom board. But I'm not sure whether the problem is with Schema or PCB footprint.  I've attached the unverified schema and footprint also with this post. Interested are welcome to give a try! If you come up with a better design you are welcome to share it with me at any time ;-)

    @Gulam This is cool. Thank you for sharing!
    Are you looking at accelerometer patterns. How do you know what letter to select?
