PROGRESS
This week I have continued adding components to the circuit, and will post pictures of the progress as soon as I get the chance. I have been working on how the sensors will be placed on the glove, and sewing the sleeves that will hold some of them in place. I have also been working on the programming code that I will need to make this project work. The programming is very tedious and repetetive, you have to test and try, test and try, etc. What I am doing is obtaining the sensor output on the LCD screen, and then using that value to make if statements for the final code. In the end, if the conditions for the if statements are met, then it will produce the programmed output, which in my case will be a letter of the alphabet.
This is a brief example of one of my statements.
if((pointer>190) && (pointer<230) && (middle>260) && (ring<340))
{
LCD_Custom_out(2, 8, “C “);
}
This letter C will only be output on the LCD screen if the conditions next to the if statements are met. If the sensor on the pointer finger shows a value between 190 and 230, the middle finger sensor shows greater than 260, and the ring finger sensor shows less than 340, then the LCD will show the letter C. The actual code is more involved, but this simple example should help one to understand the process in determining the correct gesture being signed by the user.
