An input device including a keyboard having a plurality of key assemblies, each of at least a subset of the key assemblies including a key cap having a top surface configured to be contacted by an input object, a key base disposed underneath the key cap and including a capacitive sensor, and a deformable dielectric disposed between the key cap and the key base. A camera setup point 606, which is a setup point of the virtual camera 609, is settled so that the camera setup point 606 approaches a camera chasing point 604 settled to the rear of a position 602 on a line which passes through the position 602 of the object 601 and parallel with a moving direction of the object, from a camera setup point 606 obtained at least in the last calculation. The intraplantar pin has a shank which is intended to be implanted in the cavity of the implant and a transmucosa connection head lying above the implant.
