Abstract. In the context of automotive, Human Systems Interactions Design is a great challenge, taking into account the road safety issues and the complexity of the driving task under high time constraint. To support this task, existing on-board systems display mainly visual messages, forcing the drivers to move their eyes away from the road. This paper presents an overview of studies related to drivers' perception and cognition when this information is displayed on the windshield (Head-Up Display or HUD), as it can be a solution to reduce the duration and frequency drivers look away from the traffic scene. Nevertheless, HUD might have also shortcomings raising new critical contexts, which are discussed. The Augmented Reality (AR) concept is also presented, as this solution can bear HUD potential drawbacks such as the risk of occluding relevant objects of traffic as well as phenomena like perception tunneling and cognitive capture.

Infracentimetric cervical lymph node metastasis is a factor of poor prognosis, and may represent a different, more aggressive lymphatic process. We suggest complete neck dissection by the surgeon and meticulous analysis by the pathologist, the results of which guide complementary therapy. Close surveillance of recurrence is also recommended.
