Description of the Prototype:

The prototype consists of a translucent TPO foil, which works as a touch interface. On the back of this foil, a printed mask is applied with symbols corresponding to the desired buttons. These symbols are printed in a way that is not visible when there is no back light. When the light source is activated, the symbols will be revealed, thereby revealing the buttons to the user.

This creates a dynamic interface, where button symbols are visible only when needed, providing a seamless surface, without symbols when the light is off - hide-until-lit effect.

Advantages:

• Hide-until-lit: The surface remains clean and without visible symbols when the light is off, providing an elegant and minimalist aesthetic to the vehicle interior.
• Dynamic Interface: Button symbols appear only when the light source is on, making the interface more dynamic.
• Seamless: By replacing physical buttons with this dynamic button interface, we eliminate the spaces between physical buttons, providing a smoother and integrated surface.
• Customization: The printed mask can be easily customized to display different sets of symbols, allowing greater design flexibility and adaptation to user preferences or vehicle requirements.
