The idea behind SoundOfMotion started from hybrid cars. Well, the problem of their silent engines. We decided to create an electronic sound simulator which could produce a realistic simulation of motion with a sound and be customized with different sound themes.

We quickly realized that not only hybrid cars pose a silent problem. Bicycles are silent too. Though, they pose a lesser danger for pedestrians than hybrid cars but put cyclists at a disadvantage on busy streets. After all, in traffic, people rely not only on vision, but subconsciously, on hearing too. We didn't want to add more noise, so we decided to make it sound - distinctly unusual yet noticeable through the traffic noise.

One of the challenges was to create a highly sensitive, accurate, yet simple motion sensor. Traditional spoke-attached sensors take at least one full 360 degrees revolution of a wheel to detect motion. For reliable sound simulation, it was just not good enough. You don't want to hear a breaking sound 5 seconds after you stop. Thus, we invented new technology to measure as little as 1 degree of wheel motion, about 360 times more accurately than traditional cycling sensors.

Finally, we settled on a mobile phone as a computing device. Why? Because everybody has one! As a result we created the first Mobile Bicycle Computer - VeloComputer ^TM, which is highly accurate, feature- rich and sound.

While we continue enhancing VeloComputer ^TM for mobile devices, we are also working on sound simulation and safety devices for hybrid, electric, fuel cell and other alternative vehicles, helping make our planet greener and our streets safer.
