I obtained my PhD in 1997 on studying electroweak physics with the DEPHI detector at the LEP e+e- collider. During these years, my activity was entirely devoted to data analysis. But considering particle physics requires contribution in different fields, I devoted the following 5 years to design and built a silicon strip detector for the STAR experiment at the RHIC heavy ion collider. And then I dipped back to data analysis with the STAR data to study thermo-hydro-dynamics of quantum chromodynamics (often called quark gluon plasma study). Since 2006, I have joined the group in Strasbourg who pioneered the usage of CMOS pixel sensor for tracking charged particles bringing unprecedented performances in this domain. We are now involved in several upgrades of running experiments: STAR at RHIC, ALICE at LHC, BES III at BEPC and in developments for future accelerators: ILC, CLIC, SuperB, and FAIR. Also we explore how this device may bring "new eyes" to other sciences by detecting single photons, X-rays, electrons, protons or ions. My lecture intends to provide an overview of all activities involved by tracking and vertexing with a special emphasis on the description of detection systems and not only detection techniques. We will explore the strategy of several experiments, discover their detectors and the algorithm that allows to transform series of electronics signals into intelligible objects like tracks and vertex. Our conclusion will focus on the performances obtained by present systems and expected by future ones.
