Have you ever thought of getting your workout recorded by your iPod?? Well now it is possible. Everyone knows that our iPods reacts to flips and respond to the games we are playing. This is done with the help of an accelerometer. The accelerometer is a very important part of the iPod. It makes use of electric current, silicon mass and silicon springs.
When these elements are put together, the gaming experience is simply awesome. The working of these elements go as such, fluctuation in the electric currents is caused by the measurement of the position of the silicon mass by the spring. When there is a variation in the current the LCD screen receives a different signal. This then sends a signal to the iPod to adjust the game.
This technology is what is used in the Nike- iPod. It helps one keep track of the workout done and receive updates on the distance covered, calories burnt and so on.
