In recent years, the perception and use of the car has evolved greatly in response to a growing need for mobility of different customers. Currently, a significant number of drivers spend more and more time inside their vehicles, and due to this fact, the interior of cars has become a new living space in which the human-machine interface (HMI) is becoming increasingly important. Thus, the HMI embedded in vehicles is a response to users' needs by offering among other features, the control commands of the vehicles, systems to aid the driver and multimedia services. The major automakers, attentive to this trend, have been releasing new models of vehicles on which the HMI has its place of prominence. This work mainly aims to present some examples of recent innovations in HMI and also draw a survey of the horizons and boundaries of HMI in the future.
