1. A user interface system comprising:
- a display device comprising rows of pixels; and
a detection device for detecting an actuation member, the detection device covering the rows of pixels of the display device, the detection device comprising;
rows of photon sensors separated by dielectric transparent strips, each of the dielectric transparent strips covering at least one of the rows of pixels; and
a plurality of lenses, each of the lenses at least partially covering one of the rows of photon sensors, and each of the lenses having a central portion which only covers at least one pixel of one of the rows of pixels,wherein each of the lenses comprises a non-planar surface comprising said central portion,wherein, for each of the lenses, a surface area of an orthogonal projection of the central portion on a plane containing the rows of the photon sensors is greater than or equal to 50% of a surface area of an orthogonal projection of a non-planar surface on said plane, andwherein the lenses are separated from one another by an opaque material.
