Human Factors Pack
The Human Factors Pack brings all the necessary tools and interfaces to measure and analyze a driver’s behavior: head movements, eye movements, breathing, heart rate, physio measurements, video recordings, connection to virtual reality systems (Oculus, HTC…)
Engineers can evaluate the driver’s performance and behaviour and carry out studies on fatigue, drowsiness, hypovigilance, effect of drugs, driving under the influence… All without putting in danger the driver and other road users.
The Human Factors Pack is also widely used to describe the user interfaces of vehicles: does the HUD naturally fall before the eyes? How does the user get appropriated with the suggested man to machine interface? Do the eyes leave the road less often, is the driver paying more attention, does the honk not induce too much stress…
Used in the very beggining, the Pack, therefore, makes it possible to decide whether or not to go on with the developpement of any particular concept of the HMI. When used a bit later in the cycle, in the verification phase, the Pack validates and assures that the results are well in line with the specifications: with the new interface, that the driver keeps his eyes on the road 10% more than at the beginning…
Among the many benefits of the Pack are:
- Native Support: The Human Factors Pack provides native support for different types of hardware, interfaces and manufacturers: Oculus, Vive, TrackIR, SmartEye, UDP, ANT… More details can be found in the links below.
- Synchronization: A natural synchronization of measurements and images with the rest of the simulation. Engineers and scientists don’t waste time by manually synchronizing different software, or manipulating different file formats that are or not compatible together.
- Serenity: The engineer has no development to maintain or do over time. In case of a problem, they are no doubts about his own developments. This helps pin down the source of the problems and be more effective. On the other hand, the maintenance of the Pack is no longer within its purview. Finally, if new hardware is to be supported, AVSimulation’s research and development team is responsible and takes care of the change.
- Opening: If hardware or interface is not available, the Human Factors Pack has a Software Development Kit (SDK) connected with the said hardware. Do not hesitate to contact our commercial team of engineers. You might not know that the support for your hardware may already be available or that we can advise you on the best way to do it or to have it done.
AVSimulation, once again saves you time thanks thanks to our knowledges. SCANeR platform is efficient, accurate, reliable and representative. This is a all in one Pack.
Ergonomics and IHM
The purpose of this type of application is to assure that the driver is using the vehicle effectively. It’s as much about the information as it is about how you access it. A typical example : Head-up aiming systems and virtual image placement. The simulation unables you to emphezise very quickly, adjust the position, collect feedback and change the amount of information displayed. In some cases, it is possible to carry out semi-functional tests. Those can then validate the dynamic behavior of the HMI from a visual point of view, the relevance of the information displayed etc. In ergonomics and HMI, we often use sensors to track the head, eyes, fingers of experimenters… A synchronized recording of the driver and the simulation is usually done. In other cases, we will use means of virtual reality or virtual reality mixes. When it comes to studying the driver under stress, the previous measurements are supplemented with physiological measurements synchronized, too, to the simulation.
Driver fatigue, drowsiness, hypo, alertivness, effects of drugs and alcohol
The means used for the study of the driver during this types of studies are very much the same. Usually, we will follow the physiological data, the head and eyes the movement and all the experimentation will be recorded in order to be played and analyzed.
Infrastructure and transport studies
The goal is to make sure that all the Human Factors Pack resources are used in order to confirm that the signs on the ground, the lines, the arrangement of entries and exits of the highway do not cause a problem of understanding. Those decisions can be made in time by the driver without putting in danger other users of the road.
|Physiological||The Physio feature is used to interact with electrophysiological devices.|
|Video||The Video feature allows to record video stream coming from video cameras.|
|Eye Tracker||The aim of this features is to synchronize an eye tracker system with SCANeR studio simulation environment|
|Head Tracker||The aim of the Head Tracker feature is to interface with position tracking devices that can be used, for example, to position the view point used by the Visual feature depending on the driver’s real head position/orientation.|
|Head Mounted Display (HMD)||The Head Mounted Display feature is used to interface an HMD device, like Oculus and HTC Vive.|
|Augmented Reality||The Augmented Reality feature provides a full set of function for Augmented Reality applications to allow fusion between real images acquired from a camera and synthetic images. It includes the tools to set-up the complete solution, from stereo camera calibration to the final rendering display.|
