Flight attendants had a similar idea on importance of activities of passengers, but they valued some activities as more satisfactory.
The Human-Centered Design methodology advocates VR prototyping, as an effective tool to evaluate concepts in a cost-efficient, time-saving way. It is the question of whether it works in the development of a product intended to increase privacy while flying.

The current study aims at the application of virtual reality on the evaluation of a new privacy bubble called PRIVA for the passenger cabin.

An interactive VR was created and aligned with the HTC VIVE headset. 40 participants took part in the experiment as well as in the post-experiment survey.

The concept was in overall, desirable as it was perceived to be more private, comfortable, satisfactory, effective, and appealing to participants compared to the current seat experiences. https://www.selleckchem.com/products/ms-l6.html It was also perceived as more satisfactory with regards to the activities.

The VR was effective, although there are limitations, the product seems promising and should be developed further.

More and more people choose to travel by high-speed railway. The seats in these vehicles are an important contact point and comfort of the seat cushions needs attention.

The aim of this study is to choose among three seat cushions, the one that creates most comfort for a high-speed train.

Twelve healthy volunteers were selected to participate in the experiment. Three different surface shape models of high-speed railway seat cushions were used. The Seat Pressure Distribution Index (SPD%) was calculated and analysed. A 7-point Likert scale questionnaire was applied for subjective evaluation.

The evaluation is based on subjective and objective data. The results showed that the front protruding cushion made the pressure distribution more even, while the flat cushion had the smallest SPD% and the static pressure was most evenly distributed. This knowledge was beneficial for the design of comfortable high-speed railway seat cushions.

The contrast between a bright computer screen and a dark ambient environment may influence comfort of the users, especially on their eyes.

The objective of this research is to identify the optimal desktop lighting for the comfortable use of the computer screen in a dark environment.

An experiment was designed where seven illumination setups were introduced for the users to perform their leisure tasks on a computer screen. Fifteen healthy subjects participated in the experiments. During each session, durations of the eye blinks, fixations and saccades of the user were recorded by an eye tracker. His/her neck and trunk movements were recorded by a motion tracking system as well. The comfort/discomfort questionnaire, localized postural discomfort questionnaire, NASA task load index and computer user questionnaire were used to record the overall comfort/discomfort, the local perceived physical discomfort, the cognitive workload, and general/eye health problems, respectively.

Subjective and objective measurement results indicated that users felt more comfortable with high intensity warm lights using a computer screen. We also identified that the eye fixation durations, as well as the scores of two questions in the computer user questionnaire, have significant negative correlations with comfort. On the other side, the durations of blinks and the scores of three questions in the computer user questionnaire, were significantly correlated with discomfort.

The warm (3000K) and high intensity (1500 lux) light reduced the visual and cognitive fatigue of the user and therefore improve the comfort of the user during the use of a computer screen.

A robust rail seat comfort assessment can inform the GB rail industry when procuring new seats and identify areas for comfort improvement in the refurbishment of existing seats, improving the customer experience.

To take a multifactorial approach to measuring comfort and to create a robust seat comfort assessment method for the GB rail industry.

Seat comfort assessment scores were developed by identifying seat dimensions (e.g. Seat height, seat width, seat depth), seat pad thickness and hardness requirements, seat accessories and seat attractiveness components. Scores for each seat feature were verified by conducting a fitting trial and asking 7 participants to rank dimensions through a range of adjustment. The combined scoring of features was verified by asking 14 participants to rank seats in three configurations (<minimum comfort; minimum comfort;>minimum comfort). The seat comfort dimensions scores were then validated by ranking seven existing rail seats using the assessment method and comparing the ranks with subjective comfort ranks of 12 participants.

The validation testing resulted in a moderate positive correlation, indicating an alignment between the seat comfort assessment method and subjective comfort scores.

A multifactorial seat comfort assessment has been shown to be a good indicator of passenger seat comfort.

Aircraft passengers' physical activity levels are often limited during flight for extended periods of time, which can have serious impact on health, comfort, and passenger experience. However, several factors, such as limited personal space and social factors, can make movement difficult.

The study aimed to identify participant behaviour and postures during medium to long-haul flights and their effect on location and severity of physical discomfort. This work investigated how aircraft passengers' comfort ratings changed over time and explored the association between postures and comfort ratings during flight. The study also explored the association between performing in-flight exercises and factors limiting participants' abilities to complete these exercises.

Twenty-nine participants sat in an aircraft simulated cabin for 180 minutes and periodically performed in-seat exercises. They also completed a questionnaire providing data on demographic information, self-reported discomfort scores for multiple areas of the body, which types of exercises participants performed, and qualitative comments about discomfort.
