Abstract This study investigates the legibility of China’s high-speed railway map through eye-tracking measurement. The information searching process was identified by conducting: (1) Scoping stage – a user performance test and interview to inform the design of the eye-tracking study; (2) In-depth stage – an eye-tracking study. A number of visual design problems with the map have been identified. This research explores user-centered design map solutions and provides detailed design guidance for transit maps. It also demonstrates that eye-tracking is an effective method of evaluating the design quality of a transit map as it can identify design limitations and user needs.

Insight Into

Experience shows that the reliability of large turbogenerators depends substantially on the quality of detail design, particularly the quality of the mechanical design. In addition to the design problems common to all high-speed rotating machinery, the mechanical design of generators must take account of certain electrical requirements. This paper gives an insight into the detail mechanical design of large turbogenerators paying particular attention to the interaction of electrical requirements on the mechanical design.

Indonesia tourism develop significantly. However, foreign tourist development in Indonesia is still fluctuating. The Indonesian government is optimizing the website in order to increase the number of tourists. The website plays a significant role in many aspects of tourism, especially in information search and decision-making behaviors. Information quality, service quality, and design quality are components that construct destination website quality confirmation. Destination website quality confirmation, destination website satisfaction, and willingness to visit are three major elements for researchers in examining how tourists decide to visit tourism destination via tourism website. The purpose of this research is to analyze the correlation between the qualities of the destination website and destination website satisfaction and the subsequent effects on willingness to visit a tourism destination in Indonesia. The research collected in three cities in Indonesia, namely, Batam, Jakarta, and Denpasar. The methodology is by examining 500 foreign tourists who already have used the wonderful Indonesia website. Demographic characteristics include sex, age, education, job, and nationality. The research employs 22 question items. The data were analyzed by using structural equation modeling (SEM). The results show that information quality has the greatest impact on destination website quality confirmation. In addition, the destination website quality confirmation influences website satisfaction. Finally, by this satisfaction, the tourist decides to visit the destination. This study contributes to the academia, government, and industry to more fully understand what tourists need before they decide to travel..

Psychological Well Being

Using the “user-centered” design perspective and the construct of design “humanization” as theoretical underpinnings, this field study verified the role of “objective” design quality of residential facilities for the elderly in the prediction of “subjective” users’ psychological responses. A sample of over-65-year-old adults (N = 114) was recruited in eleven residential facilities, which differed for the degree of “objective” design humanization (rated on the basis of a design expert assessment). Participants had to fill in a questionnaire including measures of both specific perceived environmental qualities (spatial-physical and social-relational) and more general psychological responses (such as residential satisfaction and psychological well-being). Outcomes revealed that older residents living in high-humanization structures show higher scores of residential satisfaction, psychological well-being and perceived environmental qualities than those living in low-humanization structures. Moreover, significant correlations emerged between specific perceived environmental qualities of the facility and general psychological outcomes. These results confirm the importance of design features for supporting elders’ needs and fostering their quality of life.

The purpose of this article is to propose 4 dimensions for consideration in hearing aid fittings and 4 tests to evaluate those dimensions. The 4 dimensions and tests are (a) working memory, evaluated by the Revised Speech Perception in Noise test (Bilger, Nuetzel, & Rabinowitz, 1984); (b) performance in noise, evaluated by the Quick Speech in Noise test (QSIN; Killion, Niquette, Gudmundsen, Revit, & Banerjee, 2004); (c) acceptance of noise, evaluated by the Acceptable Noise Level test (ANL; Nabelek, Tucker, & Letowski, 1991); and (d) performance versus perception, evaluated by the Perceptual–Performance test (PPT; Saunders & Cienkowski, 2002). The authors discuss the 4 dimensions and tests in the context of improving the quality of hearing aid fittings.

The harmonic reducer, with its advantages of high precision, low noise, light weight, and high speed ratio, has been widely used in aerospace solar wing deployment mechanisms, antenna pointing mechanisms, robot joints, and other precision transmission fields. Accurately predicting the performance of the harmonic reducer under various application conditions is of great significance to the high reliability and long life of the harmonic reducer. In this paper, a set of automatic harmonic reducer performance test systems is designed. By using the CANOpen bus interface to control the servo motor as the drive motor, through accurately controlling the motor speed and rotation angle, collecting the angle, torque, and current in real time, the life cycle test of space harmonic reducer was carried out in high vacuum and low temperature environment on the ground. Then, the collected data were automatically analyzed and calculated. The test data of the transmission accuracy, backlash, and transmission efficiency of the space harmonic reducer were obtained. It is proven by experiments that the performance data of the harmonic reducer in space work can be more accurately obtained by using the test system mentioned in this paper, which is convenient for further research on related lubricating materials.

Experiments on mechanical deformable vocal folds replicas are important in physical studies of human voice production to understand the underlying fluid–structure interaction. At current date, most experiments are performed for constant initial conditions with respect to structural as well as geometrical features. Varying those conditions requires manual intervention, which might affect reproducibility and hence the quality of experimental results. In this work, a setup is described which allows setting elastic and geometrical initial conditions in an automated way for a deformable vocal fold replica. High-speed imaging is integrated in the setup in order to decorrelate elastic and geometrical features. This way, reproducible, accurate and systematic measurements can be performed for prescribed initial conditions of glottal area, mean upstream pressure and vocal fold elasticity. Moreover, quantification of geometrical features during auto-oscillation is shown to contribute to the experimental characterization and understanding.

The concept of transporting medical products by drone is gaining a lot of interest amongst the medical and logistics communities. Such innovation has generated several questions, a key one being the potential effects of flight on the stability of medical products. The aims of this study were to quantify the vibration present within drone flight, study its effect on the quality of the medical insulin through live flight trials, and compare the effects of vibration from drone flight with traditional road transport. Three trials took place in which insulin ampoules and mock blood stocks were transported to site and flown using industry standard packaging by a fixed-wing or a multi-copter drone. Triaxial vibration measurements were acquired, both in-flight and during road transit, from which overall levels and frequency spectra were derived. British Pharmacopeia quality tests were undertaken in which the UV spectra of the flown insulin samples were compared to controls of known turbidity. In-flight vibration levels in both the drone types exceeded road induced levels by up to a factor of three, and predominant vibration occurred at significantly higher frequencies. Flown samples gave clear insulin solutions that met the British Pharmacopoeia specification, and no aggregation of insulin was detected.
