“…After the moving path, the participants were encouraged to move around the virtual prototypes using a finger mouse for better observation if needed. The participants rated four dimensions of customer impressions (luxuriousness, comfort, harmoniousness, and controllability) for each virtual prototype using the modified magnitude estimation rating ranging from 0 to 100 (Han et al, 1999;Yun et al, 2003). The anchors for the rating scales are exemplified in Figure 3.…”

This study aims to develop an effective and efficient method of analyzing user impressions of a product using virtual prototyping. A method to analyze the relationship between user impressions and design elements of a product using virtual prototyping was proposed, and then the method was applied to the case study of automobile interior design. Thirty-two participants in the experiment evaluated 32 different virtual prototypes of automobile interiors generated from the combination of 17 design elements. The results of the case study showed that user impressions can be well explained by design elements. Physically large design elements, such as the shapes of frontal area, center fascia, door trim, and steering wheel, were critical areas of automobile interior design. The proposed method is expected to be an effective and efficient alternative for industrial practitioners to analyze user impressions of design alternatives at the early stage of the design process.

“…The free-modulus magnitude estimation method was used, which is widely used in psychophysics to evaluate human sensation to a physical stimulus (Han, Song, & Kwahk, 1999). The subjects numerically estimated their feelings of discomfort for a given posture without any standard stimulus and a corresponding number or verbal anchor.…”

“…Before conducting the main experiment, a pretest was conducted to familiarize the subject with the ratio judgment tasks and to screen out those who lacked the ability to perform ratio judgment. In this study, "numeric estimation" and "line production" were used in the pretest, because of their wide usage and practical ease (Han et al, 1999). To determine whether the subject had the ability to perform ratio judgments, simple linear regression analyses were performed on two sets of logarithmically transformed stimuli and responses data obtained during the pretest.…”

Many Korean workers are exposed to repetitive or prolonged poor working postures, which are closely related with pains or symptoms of musculoskeletal disorders. Poor working postures in Korea were reviewed and an observational method to assess the postural load was developed. A computer-based postural workload evaluation system based on a macro-postural classification scheme was developed. The macro-postural classification is based on the perceived discomforts for various joint motions. On the basis of the perceived discomfort, postural stress levels for the postures at each joint were also defined in a ratio scale to the standing neutral posture. A neural network approach was used to predict the whole-body postural stresses from the body joint motions. A computerbased postural stress evaluation system was designed to automate the procedure for analyzing postures and enhance the usability and practical applicability.

“…First, the magnitude estimation ability of participants, which is shown in Han et al (1999), was confirmed by a preliminary experiment that estimates the number as a line length and the line length as a number. Whether or not the estimating ability was evaluated by evaluating whether the 95% confidence interval of the regression equation after the logarithmic conversion of the line length and the number includes 1.…”

“…In this experiment, heaviness of the box was evaluated by modulus method based on weight value of reference box. This method can be used when the difference between the reference stimulus and the test stimulus is not large (Han et al, 1999). In this experiment, the reference stimulus was selected as a 198g box which did not change the weight of medium size among the nine boxes.…”

This study analyzed the preference according to the weight and size of the product in order to understand how the size-weight illusion occurred in the affect dimension. For this purpose, 54 students in their twenties who have proved their size estimation ability participated in the preference evaluation experiment on the various weights and sizes of cookie products. The cookie products, for which heaviness is considered positive, used in this experiment were well known to be sold in three paper boxes. In this experiment, nine kinds of cookie boxes were prepared by combining three sizes and three weight levels of this product. The participants evaluated the perceived heaviness of the cookie box by the modulus method and evaluated the preference of the weight with the 11-points semantic differential scale. As a result of the study, among the boxes with the same weight ones of small size is significantly heavier, and among the boxes with the same size ones of heavy weight is significantly heavier. This result mean that the size-weight illusion of the object heaviness was found to be the same in this study. Likewise, preference were similar, but this study found that it did not increase more than certain weight. That is, there was a limit to the preferred weight for one size cookie box.
