Nowadays, most methods of illusion garment evaluation are based on the subjective evaluation of experienced practitioners, which consumes time and the results are too subjective to be accurate enough. It is necessary to explore a method that can quantify professional experience into objective indicators to evaluate the sensory comfort of the optical illusion skirt quickly and accurately. The purpose of this paper is to propose a method to objectively evaluate the sensory comfort of optical illusion skirt patterns by combining texture feature extraction and prediction model construction.

Firstly, 10 optical illusion sample skirts are produced, and 10 experimental images are collected for each sample skirt. Then a Likert five-level evaluation scale is designed to obtain the sensory comfort level of each skirt through the questionnaire survey. Synchronously, the coarseness, contrast, directionality, line-likeness, regularity and roughness of the sample image are calculated based on Tamura texture feature algorithm, and the mean, contrast and entropy are extracted of the image transformed by Gabor wavelet. Both are set as objective parameters. Two final indicators T1 and T2 are refined from the objective parameters previously obtained to construct the predictive model of the subjective comfort of the visual illusion skirt. The linear regression model and the MLP neural network model are constructed.

Results show that the accuracy of the linear regression model is 92%, and prediction accuracy of the MLP neural network model is 97.9%. It is feasible to use Tamura texture features, Gabor wavelet transform and MLP neural network methods to objectively predict the sensory comfort of visual illusion skirt images.

Compared with the existing uncertain and non-reproducible subjective evaluation of optical illusion clothing based on experienced experts. The main advantage of the authors' method is that this method can objectively obtain evaluation parameters, quickly and accurately obtain evaluation grades without repeated evaluation by experienced experts. It is a method of objectively quantifying the experience of experts.

When designing a performance involving people and mobile robots, the required functions and shape of the robot must be considered. However, it can be difficult to account for all of the requirements. The purpose of this paper is to discuss a mobile robot in the shape of a ball that is used in theatrical performances.

The paper proposes a mobile robot that can give the audience the optical illusion of the unique movements of a sphere by mounting a spherical light-emitting diode (LED) display on a high-agility wheeled robot.

It was found that movements that are difficult to implement with existing mechanisms can nonetheless be visualized through the use of light.

The paper proposes the concept of using pseudo-physical movements in performances with robots. The authors built a robot that visually reproduces the movements of a rolling sphere and is capable of faster movements and easier position estimations in comparison with previous spherical robots.

Presents the scientific methodology from the enlarged cybernetical perspective that recognizes the anisotropy of time, the probabilistic character of natural laws, and the entry that the incomplete determinism in Nature opens to the occurrence of innovation, growth, organization, teleology communication, control, contest and freedom. The new tier to the methodological edifice that cybernetics provides stands on the earlier tiers, which go back to the Ionians (c. 500 BC). However, the new insights reveal flaws in the earlier tiers, and their removal strengthens the entire edifice. The new concepts of teleological activity and contest allow the clear demarcation of the military sciences as those whose subject matter is teleological activity involving contest. The paramount question “what ought to be done”, outside the empirical realm, is embraced by the scientific methodology. It also embraces the cognitive sciences that ask how the human mind is able to discover, and how the sequence of discoveries might converge to a true description of reality.

This study aims to test the effectiveness of a training intervention based on the psychology of perception, delivered to young Italian workers and employees, with low education, hired with an apprenticeship contract and involved in a compulsory training course (duration 32 h; the training intervention reported in the paper covers the first 8 h) whose aim was to let them develop such relational competencies as communication and cooperation with others.

By making use of optical-geometric illusions and ambiguous figures, participants were accompanied through a training intervention with the dual purpose of undermining their naive certainties about why they see what they see and increasing their awareness of how the perceptual processes work. At the beginning of the intervention, at the end of the 32 h (that is, after about a month) and after about one year from the end of the course, participants were administered a questionnaire to monitor the results of the training course by measuring their “perception awareness”.

“Perception awareness” increased from the beginning to the end of the course and still scored higher after one year. “Perception awareness” was positively related to communication and cooperation.

Although the literature is full of training courses delivered to improve communication and cooperation with others, little research has been carried out on perception-based training interventions delivered to young adults with low education hired with an apprenticeship contract for which this kind of training is compulsory.

This paper aims to suggest that individuals are either consciously or non‐consciously aware of the left‐right (forward/backward) orientation of numeric digits. The purpose of the studies is to demonstrate that the “directionality” (left‐ or right‐facing nature) of numerals, and the resultant eye movement bias that this directionality creates may affect the degree to which consumers attend to, or focus upon, the various digits in a price. The degree of attention paid to these digits will, in turn, impact consumers' price‐encoding strategies. It is argued that the use of left (right)‐facing digits may increase (decrease) the likelihood that consumers will employ a truncation (i.e. rounding down) price‐encoding strategy.

The paper contains two experiments. In Experiment 1, subjects were exposed to one of four ads containing regular and sale prices. The prices were placed at opposite ends of the Mueller‐Lyer illusion, with the prices substituting for the “extraneous stimuli” (i.e. inward‐ or outward‐facing wings) in the illusion. In Experiment 2, subjects were exposed to one of six ads containing a sale price only.

In Experiment 1, digit “directionality” was found to cause eye movement bias, which resulted in distorted physical distance perceptions. In Experiment 2, digit directionality was found to impact price‐rounding behavior.

It is suggested that perceived digit‐directionality creates eye movement bias, and that eye movement bias may impact the manner in which price digits are recalled and encoded. Eye movement bias can be inferred from the results of Experiment 1, but it is not directly measured. It is suggested that future research efforts might employ eye‐tracking measures to more directly confirm that this perceptual bias does indeed occur.

The findings have important implications for the marketing practitioner, because they demonstrate that the use of particular digit combinations can result in a price being perceived as greater or less than its actual value.

In presenting the concept of “digit‐directionality”, the paper offers an entirely new rubric in which to examine matters pertaining to numerical cognition.

Properly conceived, conducted and interpreted, motivation research can be an extremely powerful management tool, designed to help the manufacturer or advertiser to sell more goods. Its aim is to expose the market situation, explain it and suggest courses of action which will lead to desired changes. It is a way of looking at a problem rather than a collection of specialist techniques and is strictly practical. Hence it can be used alongside other market research tools for the solution of marketing problems and can be applied to a wide range of business activities. Much of its development has been in the advertising field but it can also help in the formulation of production policy, solving packaging problems and marketing operations. It is examined here in all these contexts. The idea of motivation research, the reasons for its use and the techniques by which to apply it are discussed, as well as the pitfalls that are likely to occur. New and imaginary case studies are used throughout to illustrate points. A review of the subject literature is included.

This chapter explores the multiple levels of authenticity involved in son et lumière and projection mapping. Light shows are increasingly staged at historic sites, using monumental buildings as canvases. The use of light allows the buildings to communicate, giving them a performative, additional dimension, generating multiplicity, where the same architectural structure or place is encountered simultaneously in both its light and physical forms. The effect is hyperreal, transforming buildings into simulacra, versions of distorted reality, where no original exists. As the building appears to move, the mind simultaneously informs the viewer that it is static, evoking a co-created tourist experience. Light shows, arguably staged by “imagineers”, reflect the increasing move toward the spectacle essential for creative and experience economies.
