Yves wants this phone to deliver a good physical experience to the user and therefore paid special attention to design elements such as the phone’s weight, its balance, the ways the keys feel when pressed, and the various materials and textures used.

As part of the engineering process, we were tasked to ensure that the keys had a very satisfying sound and feel. The gentle, crisp mechanical ‘click’ the user feels and hears when pressing the keys is the result of exploring many different techniques, as well as extensive tuning and fine-tuning the chosen route. The drawings shown here are part of the mechanism underneath the keys that has helped us achieve this.
