Preference Experiment

In order to study the aesthetic preferences of individuals in terms of wood color, the authors explored the preference for red sandalwood and wenge wood of different hues and lightness values through a combination of an eye movement technique and subjective evaluation. The experimental results showed that: (1) sex factors had a significant effect on the eye movement indexes in a modern aesthetic preference experiment; (2) the preferences of the subjects varied slightly with different wood types but in a lower range; and (3) the effective eye movement indexes in this study were fixation duration, number of fixations, and number of last-sampling positions; in addition, there were differences in the effective eye movement indicators in different experiments. The subjects preferred a low lightness value or color of the chair.

Summary This is an attempt at examining Zygmunt Krasiński’s opinions and preferences with regard to the fine arts, a theme many critics believed to be missing from his writings. While putting things right, this article looks at the issues involved in his artistic choices, for example, what works or artists attracted his attention, in general, and to the point of him actually drawing on them in his own work or provoking him to some response (critical, approving, emotional, etc.). Furthermore, the article tries to explore the reasons and circumstances which may account for Krasiński’s interest in a given painting, print, or sculpture. It may have been the work’s theme as in the case of his ekphrasis of Ary Scheffer’s Dante and Virgil Encountering the Shades of Francesca and Paolo Di Rimini, where literary tradition provided the impulse, or the mode of its execution, or the personal ties with its author, or, finally, some other factors, like a current vogue or simply Krasiński’s individual sensitivity. The ultimate aim of all these inquiries is to outline Krasiński’s relationship with the arts (beaux arts) in the context of the aesthetic preferences of the epoch.

Video Lectures

The purpose of this study was to detect mind-wandering experienced by pre-service teachers during a video learning lecture on physics. The lecture was videotaped and consisted of a live lecture in a classroom. The lecture was about Gauss's law on physics. We investigated whether oculomotor data and eye movements could be used as a marker to indicate the learner’s mind-wandering. Each data was collected in a study in which 24 pre-service teachers (16 females and 8 males) reported mind-wandering experience through self-caught method while learning physics video lecture during 30 minutes. A Tobii Pro Spectrum (sampling rate: 300 Hz) was used to capture their eye-gaze during learning Gauss's law through a course video. After watching the video lecture, we interviewed pre-service teachers about their mind-wandering experience. We first used the self-caught method to capture the mind-wandering timing of pre-service teachers while learning from video lectures. We detected more accurate mind-wandering segments by comparing fixation duration and saccade count. We investigated two types of oculomotor data (blink count, pupil size) and nine eye movements (average peak velocity of saccades; maximum peak velocity of saccades; standard deviation of peak velocity of saccades; average amplitude of saccades; maximum amplitude of saccades; total amplitude of saccades; saccade count/s; fixation duration; fixation dispersion). The result was that the blink count could not be used as a marker for mind-wandering during learning video lectures among them (oculomotor data and eye movements), unlike previous literatures. Based on the results of this study, we identified elements that can be used as mind-wandering markers while learning from video lectures that are similar to real classes, among the oculomotor data and eye movement mentioned in previous literatures. Additionally, we found that most participants focused on past thoughts and felt unpleasant after experiencing mind-wandering through interview analysis.

The debate over the aesthetic pleasingness of the golden section is still ongoing, over 100 years after Fechner's pioneering investigations. The present study attempts to advance the debate by investigating the role of context in determining which rectangular proportions are preferred. Participants were shown three different ranges of proportions in three different orders. The order of presentation of ranges influenced aesthetic preferences most when the first range presented contained relatively “thin” rectangles. However, when the first range presented contained relatively “thick” rectangles, or had the golden section as its mid-point, then the most preferred proportion was in the vicinity of the golden section. These results are discussed in relation to the current controversy concerning the aesthetic significance of the golden section.

Eye movement data were collected and analyzed from 16 participants while they read text from a computer screen. Several text presentation formats were compared, including sentences as part of a full paragraph, sentences presented one by one, sentences presented in chunks of at most 30 characters at a predefined rate, and line-by-line presentation fitting the width of the computer screen. The goal of the experiment was to study how these different text presentation modes affect eye movement metrics (fixation duration, fixations per minute, regressions, etc.). One-way repeated measures ANOVA revealed that differences in presentation format have a significant effect on fixation duration, number of fixations per minute, and number of regressions.

DOI: https://doi.org/10.14746/ikps.2018.22.10 The aim of the study was to determine whether the age of the audience of the exhibition influences the assessment of aesthetic preferences of artistic products made up by people with visual impairment. The research was conducted to give an answer if there are differences in the preferences of different categories of artworks created by artists who are blind or low vision. The research consisted in the evaluation of raised-line drawings, photographs, sculptures and the tactile picturebook. These artistic products were presented in the art gallery. The assessments were made on a 5-point scale, where the respondents indicated how much they liked the artworks they were watching. In the study participated 118 people, including 80 children and 38 adults. It turned out that age and type of art had an interactive impact on the aesthetic assessment. Age differences in aesthetic preference werefound in reference to drawings and picture books. The visual art created by people with sight impairment was evaluated very positively.

In this article, we attempted to examine the issue of the existence of differences in eye move-ment of school-age students as they solve tasks of different difficulty levels in the sciences and natural sciences (computer science, mathematics, physics, biology). Categories of the task’s difficulty level were established on the basis of two types of criteria: subjective (an evaluation made by the subjects) and behavioural (connected to the correctness of their solution). The relationships of these criteria with the visual activity parameters, which were considered to be indicators of mental effort, were identified. An analysis of the data obtained enabled the observation of discrepancies in categorizing difficulties of the tasks on the basis of subjective and behavioural criteria. A significant and strong correlation was noticed between task difficulty level, determined by the percentage of correct answers, and the fixation parameters, although such a relationship with the blink parameters was not found. There was no correlation of the activity of the eye movement parameters, considered to be mental effort indicators, with a student’s opinion about the task’s difficulty level. On the basis of the investigations made, it can be stated that the fixation duration average can be taken as an index of the difficulty level of the task being solved.

The development of freeway construction and the increasing coverage of the road network have led to increasing requirements for guide signs. This article investigated drivers’ visual cognition pattern regarding exit guide signs on freeway interchanges. A static visual cognition experiment with 32 participants was carried out. The route information volume (four levels) and destination information volume (seven levels) were selected as the variables. An eye-tracking system was utilized to record drivers’ eye movement indicators, such as eye movement time, saccade frequency, seek time, and fixation duration. The results indicated that the eye movement time, saccade frequency, and seek time are highly correlated with information volume and increase significantly with the increases in information volume; although the fixation duration has no correlation with information volume, the fixation duration value, saccade frequency, and seek time of destination information are significantly higher than those of route information, and the destination information fulfills a stronger guiding function during the driver’s trip. The corresponding threshold values of destination information are 5, 5, 4, and 3 under the four levels of route information, and the threshold value of route information is 3.

Background. The upper lip-nose complex contributes significantly to the concept of symmetry and proportion of the face. A study of the morphology and aesthetic preferences of the lip-nose complex will provide a database that will serve as a guide for reconstruction. Subjects and Methods. Hundred Nigerian children participated in this study. Demographic data and standard photographs of the philtral column and nostrils were obtained. Sixty volunteers were recruited to evaluate the photographs. Each volunteer was asked to rank the photographs based on their aesthetic preference. Results. The morphology of the philtral columns was classified into four groups: (1) triangular, (2) concave, (3) flat, and (4) parallel. The nostril shape was also classified into four groups: (1) triangular, (2) round, (3) teardrop, and (4) rectangular. In both genders, the triangular shape of philtral column was the most common. There are significant age differences in the aesthetic rankings of philtral columns and nostril shapes. Conclusion. Our study establishes the basal values for the morphometric and aesthetic parameters of the lip-nose complex of 5- and 6-year-old children in Nigeria. We hope our results and reconstructive surgery will intersect at a point to treat disfigurements of the philtrum and nostrils successfully.

Aesthetic Preferences

One of the greatest challenges in product development is creating a form that is aesthetically attractive to an intended market audience. Market research tools, such as consumer surveys, are well established for functional product features, but aesthetic preferences are as varied as the people that respond to them. Additionally, and possibly even more challenging, user feedback requires objective measurement and quantification of aesthetics and aesthetic preference. The common methods for quantifying aesthetics present respondents with metric scales over dimensions with abstract semantic labels like “strong” and “sexy.” Even if researchers choose the correct semantics to test, and even if respondents accurately record their responses on these semantic scales, the results on the semantic scales must be translated back into a product shape, where the designer must take the consumers’ numerical scores for a set of semantics and translate that into a form which consumers will find desirable. This translation presents a potential gap in understanding between the supply and demand sides of the marketplace. This gap between designer and user can be closed through objective methods to understand and quantify aesthetic preferences because the designer would have concrete directions to use as a foundation for development of the product form. Additionally, the quantification of aesthetic preference could be used by the designer as evidence to support certain product forms when engineering and manufacturing decisions are made that might adversely affect the aesthetics of the product form. This paper demonstrates how the qualitative attribute, form, cannot only be represented quantitatively, but also how customer preferences can be estimated as utility functions over the aesthetic space, so that new higher utility product forms can be proposed and explored. To do so, the form is summarized with underlying latent form characteristics, and these underlying characteristics are specified to be attributes in a utility function. Consumer surveys, created using design of experiments, are then used to capture an individual’s preference for the indicated attributes and thus the form. Once preference is summarized in the utility function, the utility function can be used as the basis for form generation and modification or design verification.
