“…Recent research has found that the interference of continuous flicker can reduce users' visual fatigue via peripheral vision (Zhao et al, 2021). This inhibition effect persisted when the visual flicker was task-irrelevant and out of attentional focus, but disappeared when the visual flicker was moved from the central field to the periphery (Yuan et al, 2021). Similarly, studies have shown that users' visual fatigue can be reduced by changing the frequency of dynamic flickers (Sato et al, 2021).…”

PurposeThe implementation of interaction design concepts to facilitate communication between users and shopping websites has gained increasing attention in recent years. Mouse hover is a vital interaction method for users to access shopping sites and significantly impacts their decision-making experience. A well-designed mouse hover function can effectively enhance the user's search performance and improve the user experience. The purpose of this study is to investigate whether the dynamic prompt designs at the hover position and the degree of feedback transparency may affect the user's task performance and personal feelings when operating the hover function on the shopping website.Design/methodology/approachThe study employed two independent variables in the experiments: dynamic prompt and background transparency of hover feedback. A between-subject design of 2 (single flicker and continuous flicker) × 3 (transparency at 0%, 25%, and 50%) was adopted in the experiment. A total of 60 participants were invited to participate in the experiment using the purposive sampling method. Participants were asked to complete four operation tasks, and the time of each was recorded. They were then asked to complete the system usability scale (SUS) questionnaire and conduct subjective evaluations before they were briefly interviewed.FindingsThe generated results revealed that: (1) In the interaction with a shopping website, the degree of background transparency of hover feedback affected the participants' task performance. (2) The effect of a single flicker had significantly higher subjective evaluation results regarding the degree of rationality compared with a continuous flicker. (3) The participants' perceptions of the information clarity were affected when the background transparency of hover feedback was 50%. (4) The effect of a continuous flicker was better than that of a single flicker when the background transparency of hover feedback was 25%. The participants' attraction to a continuous flicker was significantly higher than that of a single flicker. Nonetheless, when the degree of background transparency was at 0% or 50%, the results were the opposite.Originality/valueThe findings generated from the research can be a reference for the development of hover operation in the user interface design for shopping websites.

“…The present study was the first consecutive case comparison study designed to investigate the kinetic pupillary changes of eyes with HM. In our research, the fixation red light of the Pentacam system flickered at 3.0 Hz, which could induce measurable pupillary oscillations (Miller and Thompson, 1978;Naber et al, 2013;Yuan et al, 2021). Additionally, there was a timespan of 6-8 s for redlight fixation preparation before the scanning onset, which meant the switch on of the blue light illumination.…”

“…Thus, it can be speculated that the Pentacam system could imitate the process of PLR. One of the major strengths of Pentacam is that it is a high-resolution system with a minimum resolution of 5 µm on Scheimpflug images, which is more accurate than known pupillometers (Bergamin and Kardon, 2002;Naber et al, 2013;Vartanian et al, 2015;Yuan et al, 2021).…”

PurposeTo compare if the kinetic pupillary changes differs between high myopia (HM) and low/moderate myopia by Pentacam.SettingChinese People’s Liberation Army (PLA) General Hospital, Beijing, China.DesignComparative study.MethodsIn this cross-sectional retrospective study, 44 eyes of 44 patients were recruited in the Refractive Surgery Center of Chinese PLA General Hospital. Eyes were divided into two groups according to the refractive error: low/moderate myopia (22 eyes; −2.99 ± 1.09 D) and HM (22 eyes, −12.93 ± 3.44 D). At the beginning of the experiment, we made trials of scanning one false pupil by Pentacam. All patients underwent the Pentacam examination three times. Pupillary diameters (PD) during the scan process and other parameters were measured using the Pentacam. Coefficient variations of PD (CV) during the different scanning periods were analyzed comparatively between the two groups.ResultsPentacam once time output 25 Scheimpflug images, with 13 ones during the period from 1st to 1.5th s and 12 ones during the period from 2.5th to 3rd s after the scanning onset. For the spatial order on all the 25 meridians, 13 Scheimpflug images came out when the Pentacam rotated from 60° to 153°meridians and the remaining 12 Scheimpflug images from 161° to 245° meridians. Among pupillary parameters, no statistical significance existed in PD25, PD13, and PD12 (pupil diameter’s mean from all, former 13 and remaining 12 of 25 Scheimpflug images, respectively) (P > 0.05) between the two groups. However, there were statistically significant differences in CV25 and CV13 (coefficient variation of the pupil diameters from all and former 13 of 25 images, respectively) (P < 0.001), with no statistical significance in CV12 (coefficient variation of the pupil diameters from remaining 12 of 25 images) between both groups.ConclusionTwenty-five Scheimpflug images on Pentacam had the temporal and the spatial orders. CV in eyes with HM was lower than that in eyes with low/moderate myopia in a certain period of the Pentacam scan. Kinetic pupillary size in HM changed more slowly than that in low/moderate myopia during some scanning period analogous to the phasic response of the pupil reflex.

“…Gavriysky (1991) found that simply requiring a button press to light flashes prompted less initial constriction and increased the onset latency of the resulting light reflex, and inhibition of light reflex amplitude is also found when light probes are delivered during a difficult (subtract 7), compared to a simple (add 1), mental arithmetic task (Steinhauer et al, 2000). The response to flickering light is also inhibited during presentation of multisensory stimuli (Yuan et al, 2021). Using pharmacological agents to selectively inactivate the sphincter or dilator muscles, Steinhauer et al (2015) conclude that modulation of the light reflex during difficult cognitive processing is mediated by parasympathetic inhibition, which decreases sphincter constriction, increasing pupil diameter.…”

A variety of psychological and physical phenomena elicit variations in the diameter of pupil of the eye. Changes in pupil size are mediated by the relative activation of the sphincter pupillae muscle (decrease pupil diameter) and the dilator pupillae muscle (increase pupil diameter), innervated by the parasympathetic and sympathetic branches, respectively, of the autonomic nervous system. The current guidelines are intended to inform and guide psychophysiological research involving pupil measurement by (1) summarizing important aspects concerning the physiology of the pupil, (2) providing methodological and data‐analytic guidelines and recommendations, and (3) briefly reviewing psychological phenomena that modulate pupillary reactivity. Because of the increased ease and tractability of pupil measurement, the goal of these guidelines is to promote accurate recording, analysis, and reporting of pupillary data in psychophysiological research.
