Scents may influence the perceived comfort of an environment. There are only a few studies conducted on the relationship between scent and comfort in aircraft cabin.

The goal of this research is to explore whether relationships between scents and perceived comfort can be found for passengers in an aircraft cabin.

276 participants joined an experiment in a Boeing 737 fuselage. The participants were divided into nine groups and each joined a session for 60 minutes with the exposure to different scents. The effect of the odor was measured by a set of questionnaires at the beginning and at the end of the session. Results of questionnaires were analyzed regarding the effects on the completion time, of the type of scents, of the intensity of the scent and on gender.

Significant differences were found at the beginning and at the end of the experiment regarding comfort and emotion, but sometimes no relations could be established. this website The influence of different scents on comfort/discomfort varied and changed over time. However, in all scenarios, participant' scores on emotion decreased. Additionally, the added scents influenced the linearity between the changes in comfort and discomfort.

Smell could influence the perceived comfort/discomfort of aircraft passengers over time, and different types of smells have different effects on passengers. The preferences on scents are diverse, which highlights the need for personalization in aircraft cabin design.

Aircraft seat manufacturers are making efforts to reduce seat weight while continuously increasing seating comfort.

To verify if seats with an optimally pre-shaped foam support could improve seating comfort while reducing seat weight.

The optimally pre-shaped surface was obtained from a synthesis of 95% of individually optimized compressed seat pan surfaces of a target population. Two new seats were proposed with two different cushions, one slightly softer and the other harder. Nineteen differently sized volunteers tested the two new seats and an existing seat randomly. After an assessment of initial discomfort, participants were instructed to watch a TV series for 50 minutes. A same questionnaire was used to assess both initial and longer-term discomfort. Contact forces and pressure distribution were analysed as well in-chair movements (ICM) during sitting.

The two new seats exhibited lower shear, lower peak pressure and larger contact area on the seat pan as well lower number of ICM during the 50 minutes sitting. They also had lower initial overall discomfort, though significant differences between the seats were not found after the long sitting.

Properly pre-shaped surface could be used as foam support to reduce the amount of foam while reducing seating discomfort.

Aircraft seating comfort has a significant impact on passenger on-board experience. Its assessment requires the adoption of well-designed strategies for data collection as well as appropriate data analysis methods in order to obtain accurate and reliable results.

This paper focuses on the assessment of aircraft seating comfort based on subjective comfort responses collected during laboratory experiments and taking into account seat features and passenger characteristics.

The subjective comfort evaluations have been analyzed using a model-based approach to investigate the relationship between overall seating comfort and specific seat/user characteristics.

The results show that the overall seating comfort perception is significantly influenced by the thickness of the seat pan, the backrest position (upright or reclined), the age of the passenger and the passenger perception of being comfortably supported at the lumbar region.

The adopted model-based approach allows the analysis of subjective seating comfort data taking into account their ordinal nature as well as the dependency between evaluations provided by the same subject.

The number of smartphone users is immense. People can do ever more with a smartphone. Smartphones are used everywhere, including in bed and on the sofa. The awkward postures taken in these situations affect comfort and discomfort. In designing a bed, it might be useful to know which position is comfortable for smartphone use on a bed.

The objective was to define the most comfortable trunk angle for smartphone use on a bed.

To study comfort and discomfort, 52 participants were asked to use the smartphone on a bed. The trunk angle of this bed was adjusted to 6 positions from flat to upright and for each angle the comfort and discomfort was recorded.

The results showed that the participants prefer a trunk angle range around 120 and 142 degrees. At the best trunk angle 29% of the participants felt comfort in the legs, 25% in the upper back and 16% in the shoulders. However, in this position 36% also mentioned discomfort in the lower back and 24 % in the neck.

For smartphone use a bed is preferable which enables a trunk angle of around 120-140 degrees. For the legs this is comfortable. However, for the neck and upper back the problem of discomfort still needs attention.

Cabin research is mostly based on passenger reports. However, it is also important to consider the perceptions of flight attendants as onboard service providers, since they can convey a complementary view shedding light on important aspects related to passenger experience.

This study seeks to analyze flight-attendants' perception regarding passengers' inflight activities and experience.

Twenty-eight flight attendants were interviewed on more than twenty-three inflight activities that were extracted from a brainstorming session. A survey was designed based on these activities and was distributed to flight attendants.

Overall, flight attendants perceived the activities 'resting/relaxing', 'sleeping' and 'using the restroom' for comfort as the most important activities to passengers, while activities 'talking to neighbors' and 'thinking and observing' were the least important ones. Interesting was the fact that flight attendants scored satisfaction of some activities higher then passengers.

Flight attendants had a similar idea on importance of activities of passengers, but they valued some activities as more satisfactory.
