With ongoing integration of various systems in the Vehicle, the usage of display unit is increasing day-by day. The necessity to access data, stored on a remote system, via a human machine interface (HMI) is growing and also the need for developing a Graphical User Interface (GUI) in an efficient manner. The customer/user request to view or browse the system via display is becoming more complex and it is very annoying for the customer/user to wait for a system reaction on his input to the local system for a longer time. With the above limitations we would need to develop the GUI for quick turnaround with high quality. In this paper we are about to discuss on the Model View Controller (MVC) architecture, platform based approach, modular approach based on Core - Server for GUI development, auto code generation, behavioral model simulation, reusable packages and various tools that are used in development of GUI. The selection process of GUI tools is now turning to be vital during the development phase.

Towards developing of advanced driver specific active/passive safety systems it is important to be able to continuously evaluate driving performance variations. These variations are best captured when evaluated against similar driving patterns or maneuvers. Hence, accurate maneuver recognition in the preliminary stage is vital for the evaluation of driving performance. Rather than using simulated or fixed test track data, it is important to collect and analyze on-road real-traffic naturalistic driving data to account for all possible driving variations in different maneuvers. Towards this, massive free style naturalistic driving data corpora are being collected. Human transcription of these massive corpora is not only a tedious task, but also subjective and hence prone to errors/inconsistencies which can be due to multiple transcribers as well as lack of enough training/instructions. These human transcription errors can potentially hinder the development of algorithms for advanced safety systems, and lead to performance degradations.

Abstract A human thermal comfort, which has been a subject of extensive research, is a principal objective of the climate control systems. Applying the results of research studies to practical problems requires quantitative information of the thermal environment parameters, such as the solar radiation. A photovoltaic-cell based sensor is commonly used in the automotive climate control systems for the measurement of solar radiation information. The erroneous information from the sensors can cause thermal discomfort. The erroneous measurement from sensors can be due to physical or environmental parameters. Shading of a solar sensor due to opaque vehicle body elements is one such environmental parameter that is known to give incorrect measurement. Analytical method that uses fundamental geometric principles is proposed to determine whether sensor is shaded, for a known location of the sun and for a given geometry of the vehicle passenger compartment. A corrective action to measured data when sensor is shaded that ensures thermal comfort is also presented.

As information and entertainment to and from the vehicle (Telematics) become more prolific it is critical to increase our understanding of how the driver understands and uses Telematics functions. Equally critical is how those functions impact the driver. The papers in this technical paper collection will address these issues.

This Information Report contains a definition of road vehicle hands-free operation. This definition applies to driver inputs to a wireless communications device used for person-to-person wireless communications while driving. This report applies to both original equipment manufacturers’ and aftermarket devices. The definition does not apply to outputs, e.g., visual or haptic feedback, from a communication system or device, regardless of the modality of human-machine interface. It also does not apply to parallel or redundant manual control operating modes.

Abstract Driver behavior is one of the most important factors in safe mobility. In general, various driver maneuvers can be determined from acceleration of the vehicle. Physically, the acceleration and brake can be detected with longitudinal acceleration while turning and lane change can be detected with lateral acceleration. Normally, IMU (inertia measurement unit) has been designated to get these data. However, the IMU is not convenience to install in the vehicles especially as aftermarket parts. Nowadays, navigation system technologies have been much improved, both on availability and accuracy with combination of multiple navigation satellite systems. Normally, it's called Multi-GNSS (multiple global navigation satellite system). In particular, the satellite navigation systems available in this work are GPS, GLONASS, and QZSS. With decimeter precision and the update rate scale up to 10-Hz, the GNSS can be a viable alternative for driver behavior detection. In previous studies, it was found that dangerous behaviors such as aggressive lane change required decimeter accuracy from GNSS.

This SAE Aerospace Recommended Practice (ARP) includes the minimum human factors requirements and recommendations for the flight deck display of data linked Aeronautical Information (AI), specifically Notices to Airmen (NOTAMs). The goal of human factors is to make it easy for users to do things right and hard to do them wrong. The guidance in this ARP supports this goal by defining minimum requirements and recommendations that focus on the text and potential graphics for NOTAMs as well as the human’s interaction with these on the flight deck. In this ARP “flight deck” includes both single pilot flight decks as well as multi-pilot flight decks. The FAA defines NOTAMs as any information concerning the establishment, condition, or change in any component of, or hazard to, the National Airspace System. ICAO Annex 15 defines a NOTAM as “a notice distributed by means of telecommunication containing information concerning the establishment, condition, or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to personnel concerned with flight operations.”
