Making a prototype that works, that pleases and that finds its place among the consumers' habits, also requires a clever product design strategy.

And when we talk about design, even if we immediately imagine the aesthetic contours and the beautiful finish of a product, we also include ergonomic design. A good product is a product that does not need an instruction manual: it is designed for the user, it must be easy to use, it must be quick to learn, in other words, the experience must be "user friendly".

Even if it works perfectly, the best product in the world can quickly turn into a failure if it is not attractive enough for the public, if it lacks responsiveness or is not well thought out enough and its use is complex.

Fortunately, today, access to subsidies for the development of a prototype is relatively easy. The first phase of development consists in the realization of a model which will allow to validate the design of the product, its look and its ergonomics, to then turn to the realization of a final version which includes the electronics and the integrated hardware.
