The first every smartphone in 1994 Smartphones today, 19 years later

In 1994, IBM debuted what was considered to be the first ever smartphone.  It could take phone calls, emails, and even take notes. Since then, a proliferation of smartphones have popped up over the world, giving choices to consumers while continuing to innovate the technologies behind the smartphone. One thing that has made the smartphone such a great device to play games is the accelerometer.  It is an engineering marvel; a device that can detect the direction you’re holding the phone in such a compact device.

Creative Applications

  1. How does a “traditional” accelerometer work?
  2. Watch the video for the parts of a smartphone accelerator.  What does each part represent in the the “traditional” accelerometer?
  3. Using capacitors and current, explain how smartphone accelerometers work.
