Electromagnetic pulse massage mimics the current signal of human nerve fibers by conducting a weak current to the deeper layers of the skin, which makes the muscle fibers contract and imitates massage techniques such as pounding and kneading, thus achieving a relaxing effect on the cervical spine. Wearing stability of such products largely affects the effectiveness and comfort of massage. This paper aims to investigate the wearing stability and influencing factors of electromagnetic pulse neck massagers. Three representative neck massagers were used for testing, and subjective ratings of fit were collected from 58 participants (29 males, 29females), along with measurements of wearing slipping distance and neck dimensions. The results showed that females wore the neck massager significantly more loosely than males and had a longer slipping distance of 10.256mm. Moreover, the correlation analysis indicated that the wearing fit was strongly correlated with Middle Neck Width (MNW), moderately correlated with Middle Neck Girth (MNG), weakly correlated with Root Neck Girth (RNG) and Front Neck Length (FNL), which was a guideline for the design of size and grading for neck massages.

With the development of communication technology and network, museum websites have become an important way for people to appreciate cultural relics and understand the urban culture. The museum website is the forerunner of the physical museum, and the usability of the website greatly affects the user’s experience. To systematically study the influencing factors of museum website usability, this paper used the Analytic Hierarchy Process (AHP) to construct a museum website usability evaluation system, and took the Foshan Museum website as the research object, using the classic usability testing method to evaluate the website usability, collected objective performance indicators, behavioral data, and subjective evaluations of participants. A total of 10 university graduate students participated in this experiment. The experimental results showed that the current website of Foshan Museum had problems such as confusion of information structure and lack of key information. The hierarchical structure of the website was optimized using the Hierarchical Task Analysis (HTA) method. Finally, the usability test was repeated, and the improvement of the website usability was verified through data analysis. This study also draws some general conclusions, which provide some reference value for the same type of website optimization in the future.

Head acupoint massage products imitate human massage techniques, and act on acupuncture points on the head by means of inflating, squeezing, vibrating, and heating to promote blood circulation in the head, relieve fatigue and prevent diseases. The fit of such products to the head greatly affects the effectiveness and comfort of the massage. In order to design head acupoint massage products suitable for Chinese head shape and improve the adaptation performance of product massage structure and head acupoints, this paper studies a 3D digital head-shaped platform with complete head acupoint distribution and conducts dynamic analysis of fitting fit. Firstly, the 5th, 50th and 95th percentile 3D digital head shapes of 5 types of Chinese standard head shapes were reconstructed. Secondly, 3D distribution models of 7 meridians and 78 acupoints were established on the head shape according to the theory of traditional Chinese medicine. Finally, a head-mounted massage product module was analyzed the adaptability of acupoint matching. The problems of a head acupoint massage product were analyzed by virtual wearing in the 3D digital head-shaped platform, and the head massage product was optimized. The results showed that the inner surface of the optimized product could fit well with the head, and the acupoint massage position was accurate.

Deceit often occurs in questionnaire surveys, which leads to the misreporting of data and poor reliability. The purpose of this study is to explore whether eye-tracking could contribute to the detection of deception in questionnaire surveys, and whether the eye behaviors that appeared in instructed lying still exist in spontaneous lying. Two studies were conducted to explore eye movement behaviors in instructed and spontaneous lying conditions. The results showed that pupil size and fixation behaviors are both reliable indicators to detect lies in questionnaire surveys. Blink and saccade behaviors do not seem to predict deception. Deception resulted in increased pupil size, fixation count and duration. Meanwhile, respondents focused on different areas of the questionnaire when lying versus telling the truth. Furthermore, in the actual deception situation, the linear support vector machine (SVM) deception classifier achieved an accuracy of 74.09%. In sum, this study indicates the eye-tracking signatures of lying are not restricted to instructed deception, demonstrates the potential of using eye-tracking to detect deception in questionnaire surveys, and contributes to the questionnaire surveys of sensitive issues.
