Signal Information

The vehicle signal Vehicle.Occupant.Row1.Middle.MidEyeGaze is a Branch.

UUID

Each vehicle signal is identified by a Universally Unique Identifier (UUID)

The UUID for Vehicle.Occupant.Row1.Middle.MidEyeGaze is c98236d5f2a25794977a3f1e25495345

Children

This vehicle signal is a branch or structure and thus has sub-pages:

  • Vehicle.Occupant.Row1.Middle.MidEyeGaze.Azimuth (Mid eye azimuth gaze (right-hand rule) on vehicle sprung mass Z-axis as defined by ISO 23150:2023 0 = Driver looking forward. Positive values = Driver looking at something on the left side of driver. Negative values = Driver looking at something on the right side of driver.)
  • Vehicle.Occupant.Row1.Middle.MidEyeGaze.Elevation (Elevation to observed object measured as angle between vehicle sprung mass XY-plane as defined by ISO 23150:2023 at driver mid eye position and object. 0 = Driver looking at something at same height as mid eye position. Positive values = Driver looking at something above mid eye position. Negative values = Driver looking at something below mid eye position.)
