One of the most significant developments in cockpit technology over the past several years is the emergence of a new cockpit architecture that uses cursor control devices and keyboards for interaction with individual and shared displays. This architecture has allowed for the design of cockpit interfaces with many advantages compared to traditional designs. However, there are a number of challenges associated with these new cockpits that should be addressed so that pilots will be able to take full advantage of the performance improvements available from the new designs. This thesis describes three of the major challenges associated with the new architecture: supporting awareness, assisting interruption recovery, and mitigating interaction conflicts. It also describes the analysis process used to identify these challenges and proposes an interface augmentation with the potential to address them. The proposed design uses visualizations of the history of operator interactions with the interface to provide cues to the pilots about where each of them has been (and is currently) interacting. This interaction data includes both visual (sourced from a gaze tracking system) and input (from the keyboard or cursor control device) information, and was communicated on the interface using dynamic borders around the relevant areas of the interface. This augmentation aimed to address the three identified challenges by providing pilots with: improved awareness of each other’s actions, visual cues of where they were working prior to an interruption and what has changed since, and clear indications of where each is working to allow them to avoid conflicts. A two-stage evaluation process was used to determine the utility of the interface concept in a cockpit context by developing a non-interactive video prototype and showing it to pilots. The results of the evaluation indicated that the design has sufficient potential to warrant further study, as evaluation in higher fidelity environments would help provide further evidence of its potential utility for live cockpit operations. Therefore, future work should include the development and evaluation of a fully interactive prototype for live cockpit operations, as well as further examination of the design concept’s potential for use as a training tool.

Three flight simulator experiments examined how a health monitoring system may aid pilots in detecting flight control faults. The first experiment introduced an unexpected fault in the flight control system during an approach to a fictitious airport. The second experiment used a factorial design of (1) presence ?? notof a Fault Meter display and (2) presence ?? not ?? an Alerting System, which could have one or two phased alerts. In half the runs, a fault was triggered at some point, and pilot response was recorded. The next experiment comprised one flight in which pilots were given a false alarm by these systems, testing for automation bias. No consistent pilot response was found to the faults, with pilots sometimes successfully landing the aircraft, sometimes immediately or eventually initiating a go-around, and sometimes loosing aircraft control and crashing. The pilots were not able to identify the fault in 11% of the cases. Tunnel tracking error increased following the faults and the false alarm, suggesting it may be both a manifestation of attempts to diagnose a fault and a cue to pilots of a problem. Finally, the triggering of a false alarm showed the existence of automation bias induced after a small number of interactions with the HMS.

Os motoristas de ônibus apresentam problemas de saúde física e psicológica decorrentes da exposição a fatores relacionados com a organização do trabalho e com a própria configuração do ônibus, mais especificamente da cabine, onde realizam suas atividades. Os projetos das cabines dos ônibus e do seu cockpit, interface através da qual o motorista envia comandos para o ônibus, normalmente desconsideram a opinião do motorista e a relação entre produto/usuário/contexto de uso real, fundamental para garantir um projeto de interface adequado, segundo os conceitos de ergonomia e design. Assim, esta pesquisa tem como objetivo estudar e determinar as demandas dos motoristas de transporte rodoviário e urbano de passageiros com relação aos cockpits de ônibus, a fim de propor melhorias considerando as características da tarefa e a opinião dos motoristas com relação ao seu conforto e desempenho. Participaram do estudo duas empresas de transporte de passageiros, uma rodoviária e outra urbana. A metodologia foi estruturada em três fases. A primeira (Pré-análise) teve como objetivo conhecer os cockpits dos ônibus, entender os requisitos considerados na compra de novos veículos e evidenciar as condições do cockpit que atuam na dirigibilidade do veículo. A segunda fase (Análise) consistiu em investigar a percepção dos motoristas com relação aos cockpits dos ônibus, realizado observação in loco, filmagens, entrevistas, questionário e dinâmica do protótipo de papel Na terceira fase (Pós-análise) foi realizada a triangulação dos dados para identificar os fatores de conforto mais relevantes e a comparação dos resultados dos dois grupos de motoristas. Os resultados da dinâmica convergiram com aqueles das entrevistas e questionários evidenciando que, em geral, os motoristas tendem a manter os comandos nos locais em que se acostumaram, modificando somente o posicionamento daqueles que não atendem suas necessidades de forma satisfatória. A principal demanda dos motoristas de transporte rodoviário está vinculada ao posicionamento do comando do ar-condicionado no cockpit e às condições de conforto térmico na cabine. Os motoristas de transporte urbano de passageiros, por outro lado, desejam o reposicionamento do comando do itinerário para um local de fácil alcance e visibilidade quando em sedestação. Esses também relataram desconforto térmico relacionando com a inexistência do dispositivo da ventarola, uma vez que a maioria dos veículos da frota não dispõe de ar-condicionado. Os dois grupos de motoristas indicaram a necessidade de melhorar a visibilidade do painel de instrumentos que, por vezes, é dificultado pelo mau posicionamento do volante. Além disso, os dois grupos de motoristas consideraram o espaço interno da cabine, o ruído, bem como o conforto do banco, características a serem melhoradas. / Bus drivers have physical and psychological health problems due to exposure to factors related to work organization and the configuration of the bus, specifically the cabin, where they carry out their activities.

The second phase (Analysis) was to investigate the drivers' perception regarding the cockpits of the buses through in loco observation, filming, interviews, questionnaire and paper prototype dynamics In the third phase (Post-analysis) the triangulation of the data was performed to identify the most relevant comfort factors and the results of the two groups of drivers were compared. The results of the dynamics converged with those of the interviews and questionnaires showing that, in general, drivers tend to keep the controls in the places they have become used to, modifying only the positioning of those who do not meet their needs. The main demand of road transport drivers is linked to the positioning of the air conditioning control in the cockpit and the conditions of thermal comfort in the cabin. Passenger urban transport drivers, on the other hand, want the itinerary Command relocate to a location within easy reach and visibility when in the sitting position. They also reported thermal discomfort relating to the absence of ventarola device, since most vehicle do not have air conditioning. The two groups of drivers indicated the need to improve the visibility of the instrument panel which is sometimes hampered by poor steering positioning. In addition, the two groups of drivers considered the interior space of the cabin, the noise as well as the comfort of the seat, features to be improved.

In the event of an onboard emergency, air transport pilots are remarkably adept at safely landing their aircraft. However, the tasks of selecting an alternate landing site and developing a safe path to land are very difficult in the high workload, high stress environment of a cockpit during an emergency. The purpose of this research was to develop an automated path planning aid which would assist the pilot in the completion of these tasks. A prototype was developed to test this concept experimentally. The experiment was also intended to gather further information about how pilots think about and accomplish this task as well as the best ways to assist them. In order to better understand the priorities and processes pilots use when dealing with emergency planning, a survey of airline pilots was conducted. The results of this survey highlighted the fact that each emergency is unique and has its own set of factors which are critically important. One factor which is important in many emergencies is the need to land quickly. The survey responses indicated that one of the most important characteristics of a useful tool is that it should provide pertinent information in an easy to use manner, and should not divert too much attention from their other tasks. A number of design goals drove the development of the prototype aid. First, the aid was to work within current aircraft, without requiring substantial redesign on the cockpit. Second, the aid was to help improve pilots' performance without increasing their workload. Finally, the aid was designed to assist pilots in obtaining and processing critical information which influences the site selection and path development tasks. One variation of the aid included a filter dial which allowed pilots to quickly reduce the number of options considered, another variation of the aid did not include such a dial. These two variations of the aid were tested in order to assess the impact of the addition of the filter dial to the system. Though many of the results did not prove to be statistically significant, they suggest that the addition of a filter dial improved the quality of the selected landing site; however, it also increased the time required for the selection. The results were obtained in both familiar and unfamiliar emergencies. The dial was shown to improve the time to complete the task in the case of unfamiliar emergencies. The experiment also compared an optimal ranking system to a non-optimal system, for which results showed no significant difference between the two. This may imply that while pilots did not tend to over rely on the ranking system, under-reliance may need to be addressed by training and a better understanding of the factors which impact the rankings. The participants found that the aid facilitates quick and easy access to critical information. The aid was also useful for processing this information by filtering out options which were inappropriate for a given scenario through the use of the filter dial. The participants also made recommendations about possible improvements which could be made to the system such as better filter settings which are more similar to the way that pilots think about their options.

During flight missions, fighter pilots are in general exposed to vast amounts of stress including mild hypoxia, vibrations, high accelerations, and thermal discomfort. It is interesting to predict potential risks with a certain mission or flight case due to these stresses to increase safety for fighter pilots. The most predominant risk is typically thermal discomfort which can lead to serious health concerns. Extensive exposure to high or low temperature in combination with a demanding work situation weakens the physical and mental state of the pilot and can eventually lead to life-threatening conditions. One method to estimate the physical and mental state of a person is to measure the body core temperature. The body core temperature cannot be measured continuously during flight and needs to be estimated by using for instance a human thermoregulatory model. In this study, a model of the human thermoregulatory system and the cockpit environment is developed. Current thermoregulatory models are not customized for fighter pilots but a model developed by Fiala et al. in 2001, which has previously shown good performance in both cold and warm environments as well as for various activation levels for the studied person, is used as a theoretical foundation. Clothing layers are implemented in the model corresponding to clothes used by pilots in the Swedish air force flying the fighter aircraft Gripen E in warm outside conditions. Cooling garments and air conditioning systems as well as avionics, canopy, and cockpit air are included in the model to get a realistic description of the cockpit environment. Input to the model is a flight case containing data with altitude and velocity of the fighter during a mission. human heat transfer; body temperature regulation; physiological model;cooling garment; cockpit modeling

Approved for public release; distribution is unlimited / This thesis investigates the problems in current naval aircraft cockpits as perceived by fleet naval aviators who are students at the U.S. Naval Aviation Safety School. A critical incident questionnaire provides data that examines the deficiencies of an individual aircraft. These individual aircraft deficiencies are then categorized into twelve major deficiency categories which are common to ore than one aircraft. Various recommendations are made concerning standards, specifications, cockpit research and cockpit design. / http://archive.org/details/pilotreportedhum00dani / Commander, United States Navy

Construction equipment such as wheel loaders and dumpers are constantly getting updated with new technology when it comes to performance and fuel consumption. But the interior in the cockpit has not been exposed to any dramatic changes for decades. A modernized cockpit gives the driver a more modern feel of driving a highly technological machine, while at the same time enables for personalization. This thesis work presents a new way of improving the look and feel for displaying relevant information and also relaying information to both the driver of the machine and spectators outside. It includes a way of rerouting CAN-bus signals from a construction machine and displaying it on a tablet. The core idea with the solution is to make it as modular as possible to further improve and be able to use it in any machine available at Volvo's disposal. With this in mind, any machine could use the same software, the same hardware and still be able to fully utilize all the features that have been implemented from the thesis work. The idea and implementational results are designed as partly embedded and partly towards user interface.

<p>Today’s automobile cockpit is filled with different buttons and screen-based displays giving input and relaying information in a complex human-machine system. Following in the footsteps of the early 1970s flight industry, this thesis work focused on creating a complete glass cockpit concept in the automobile.</p><p>Our automobile glass cockpit consists of three displays. A touch screen based centre console with an interface that we took part in creating during the spring of 2006. Parallel to this ongoing master thesis, a head-up display was installed by a group of students and we had the opportunity of giving input regarding the design of the graphical interface.</p><p>The third display, a LCD, replaces the main instruments displaying speed, RPM, fuel level, engine temperature etc. Together with ideas on an extended allocation of functions to the area on and around the steering wheel, creating a dynamic mode based interface replacing today’s static main instruments was the focus of this project.</p><p>After conducting a thorough theoretical study, a large number of ideas were put to the test and incorporated in concept sketches. Paper sketches ranging from detailed features to all-embracing concepts combined with interviews and brainstorming sessions converged into a number of computer sketches made in an image processing software. The computer sketches was easily displayed in the cockpit environment and instantly evaluated. Some parts were discarded and some incorporated in new, modified, ideas leading to a final concept solution.</p><p>After the design part was concluded, the new graphical interface was given functionality with the help of a programming software. As was the case with the computer sketches, the functionality of the interface could be quickly evaluated and modified. With the help of a custom-made application our interface could be integrated with the simulator software and fully implemented in the automobile cockpit at the university simulator facilities.</p><p>Using a custom made scenario, the interface underwent a minor, informal evaluation. A number of potential users were invited to the VR-laboratory and introduced to the new concept. After driving a pre-determined route and familiarizing themselves with the interface, their thoughts on screen-based solutions in general and the interface itself was gathered. In addition, we ourselves performed an evaluation of the interface based on the theoretical study.</p>
