We called it a Spedometer. So, we designed a wireless data link to send the info from your foot to a wristwatch and then to the internet. I studied History, Electrical Engineering and Computer Science in college. I've always liked to do electrical experiments and build devices with electricity. I find that electrical engineering is a lot like plumbing.
Water flows through pipes and electricity flows through wires.
One of my first experiments was to build a light bulb. The next was to build a hot dog cooker, then my first radio. I'm hoping that we get to invent a lot of sensors that will be able to communicate with watches, computers, bikes, TV's, video games and more. Running a business is hard work, and just having a good idea does not guarantee success. It takes a lot of hours and a lot of hard work and an idea you believe in.
