Despite its round and simple appearance, the Wave Ball is a product of high level technology. Several sensors combined with powerful software/hardware allow the ball to produce and increase waves with full control on wave frequency and amplitude.

Wave Creation and control
As a result of the upward thrust created by the ball, a first wave is spread in the pool. Once reflected against the wall of the pool, the wave comes back to the ball where it will be amplified. A computer system computes the right impulsion time in order to increase (or decrease) the waves.
The wave ball’s electronics allow it to compute the exact moment when the wave will return from the wall and to predict when a pulse has to be given. The wave motion is then reinforced each time a wave comes back to the ball. The amplitude will then grow until it reaches the desired amplitude level.
The wave ball principle is the same as when someone is pushing you on a swing. If the person pushes you at the right moment, the amplitude of the movement will increase, even if the force with which they are pushing is weak. In contrast, if they do not push at the right moment, and is a little bit off the phase, the movement will stop growing and then decrease.
Wave Amplitude Control Mechanism
The more the Wave Ball transmits its energy to the water, the more the height of the wave increases. So, if we want to control the amplitude of the waves, we have to control the energy that is transferred from the Wave Ball to the water.
The transfer of energy is possible only if the movement of the ball is shifted from the movement of the wave. The Wave Ball, to be efficient, has to anticipate its movement against the one of the waves. The shift between the Wave Ball movement and the wave movement is called the phase difference. It is measured in degrees (°). The ball can give more or less energy by adapting the phase difference between its movement and the wave.
