Uncovering the roles of complexity and expertise in memorizing tactical movements from videos with coach's pointing gestures and guided gaze

Background Improving the acquisition of complex tactical knowledge through video presentations has attracted considerable attention. Previous research has aimed to facilitate learning by structuring videos including pointing gestures and guided gaze. However, it is debatable whether these cues actually contribute to improved performance in the context of tactical learning for players with varying levels of expertise. Objectives The present study examined the moderating roles of content complexity and expertise level on recall scores, mental effort, and visual attention while watching videos involving coach's pointing gestures and guided gaze, as well as videos with no cues. Methods One hundred sixty novice and expert basketball learners were randomly divided into four groups: (i) simple content + no-cues, (ii) simple content + gesture/gaze, (iii) more complex content + no-cues, and (iv) more complex content + gesture/cues. They were instructed to learn the evolution of a tactical scene described by the coach, rate their mental effort invested during the learning phase, and reproduce the learned tactical scene. Results and conclusions The results showed that regardless of the complexity of the content, novices achieved better recall performance and higher visual attention in the gesture/gaze condition than in the no-cues condition. However, the results showed that experts benefited equally from both conditions when the content was simple, whereas they benefited more from the gesture/gaze condition when the content was more complex. The results showed that the effectiveness of videos involving pointing gestures and guided gaze depends on the content complexity and the expertise level.

Visual attention predictive model of built colonial heritage based on visual behaviour and subjective evaluation

Although physiological measurements, subjective evaluation and other methods have been applied to visual attention research, architects still lack a systematic quantitative classification method when assessing the visual attention to built colonial heritage. This study aimed to investigate the relationship between people’s visual behaviour and subjective evaluation when observing built colonial heritage and to construct a prediction model based on eye-movement metrics and subjective evaluation indicators to distinguish the visual attention to built colonial heritage. This study recorded data from 54 participants while observing five scenes of built colonial heritage, and the results showed that participants had different visual behaviours and subjective evaluations when viewing built colonial heritage in different scenes. And visual attention to built colonial heritage was negatively correlated with the average saccades peak velocity and average saccades amplitude and positively correlated with the average pupil diameter; visual attention was correlated with 12 subjective evaluation indicators. The eye-movement metrics and subjective evaluation indicators with correlation to visual attention were used as input variables to construct a prediction model of visual attention to built colonial heritage based on the BP neural network. Different built colonial heritage’s low, middle and high visual attention were identified with high accuracy (74.46%). This quantitative method can help architects to measure the visual attention to built colonial heritage to develop conservation and renewal strategies.

Visual Perception and Attentional Skills in School-age Children: A Cross-Sectional Study of Reading Proficiency in the Hearing Impaired.

Auditory impairment is one of the common sensory deficits that occur in humans. Hearing loss affects students' ability to communicate and read, which eventually causes social and scholastic stigma. Reading relies heavily on phonics as well as visual attention. Students with normal hearing read by transforming phonic sounds into words. Hearing impaired has little to no phonic ability, making them visual readers who rely on visual cues while reading. Present study sought to investigate factors that affect reading skills in hearing-impaired children. A cross-sectional study was conducted in hearing- and hearing-impaired schools of Ludhiana, Punjab, India. After vision screening among all students, sixty students were enrolled via convenient sampling. Higher order of visual perception, attention, and reading ability was investigated. A total of 60 students were evaluated (30 hearing impaired and 30 age-matched hearing). The hearing group was statistically better than the hearing impaired (p = 0.001), Hearing impaired were better in visual attention (p = 0.001), whereas a correlation was found between reading ability and visual perception, attention skill of hearing- and hearing-impaired students (r = 0.80, P = 0.001). Present study concludes that hearing-impaired students exhibit issues with visual-motor integration, visual-spatial relationships, and visual sequential memory. Higher visual attention was demonstrated by hearing-impaired students. The results of the current investigation revealed a correlation between visual perception and attention skills and reading competency. Thus, the present study demands that the newly enrolled hearing-impaired students must undergo a thorough ocular evaluation.

The association between visual attention and body movement-controlled video games, balance and mobility in older adults

BackgroundBody movement-controlled video games involving physical motion and visual attention may have the potential to train both abilities simultaneously. Our purpose was to determine the associations between performance in these games and visual attention, balance and mobility in a group of older adults. The long-term goal is to identify the optimal type of interactive games with regards to training potential.MethodsFifty healthy adults aged 65+ years participated in this cross-sectional study. Visual attention was measured with static and dynamic versions of a useful field of view (UFV) and a multiple object tracking (MOT) test. Balance was measured with a force plate in bi-pedal quiet stance test (QST) and one-legged stance (OLST). Gait variability and walking speed were assessed with the Five Meter Walk Test (5MWT). Four Microsoft™ Xbox® 360 Kinect™ interactive video games were chosen based on the apparent levels of visual attention demand.ResultsVisual attention (UFV and MOT) was significantly associated with performance in Xbox® Kinect™ games that appeared to have a high visual attention demand (p < 0.05), while there was minimal or no significant association with games with apparent low visual attention demand. Balance and mobility show correlations with visual attention, and with Xbox games.ConclusionThe results suggest that there are relationships between visual attention, balance, mobility and Xbox® Kinect™ game performance. Since different Xbox® games were associated with different balance, mobility and visual attention scores, a variety of such games, rather than a single game, may be most effective for training for falls prevention.

Changes in visual attentional behavior in complex regional pain syndrome: A preliminary study.

The purpose of the present study was to investigate the visual attentional behavior towards a pain-affected area and face/body images using eye tracking in complex regional pain syndrome (CRPS) patients. Moreover, we investigated the relationship between visual attentional behavior and clinical symptoms. Eight female patients with CRPS type 1 in their upper limbs and 8 healthy adult women participated in this study. First, the participants were asked to watch videoclips in a relaxed manner (Videoclip 1 featured young adults who introduced themselves; Videoclip 2 featured young adults touching the hand of the other person sitting across from them with their hand.) Eye movement data were tracked with eye-tracking glasses. In video clip 1, the fixation duration (FD) and fixation count (FC) on faces tended to be lower in CRPS patients than in healthy controls. This tendency was found in patients with low body cognitive distortions. In video clip 2, CRPS patients displayed significantly lower FD and FC on the unaffected hand while watching a video of the unaffected hand being touched compared with healthy controls. Moreover, patients with low body cognitive distortion displayed significantly longer FD on the affected hand. Some CRPS patients differed in visual attentional behavior toward the face and body compared with healthy controls. In addition, our findings suggest that patients with lower body cognitive distortion may have a high visual attention for the affected hand, while patients with higher distortion may be neglecting the affected hand.

To Fit In or to Stand out? An Eye-Tracking Study Investigating Online Banner Effectiveness in a Media Multitasking Context

Online advertising banners are often subject to banner blindness, meaning that people avoid looking at them. The current study examines whether web surfing while watching television, a form of media multitasking, influences how people respond to online ad banners. The experimental study examines whether people respond differently to an online ad banner which thematically fits with the website content (i.e., banner congruity) and which is animated (i.e., banner animation), taking into account the relevance between media tasks (whether the content of the television program and the website are related). Individuals’ cognitive (visual attention paid to the banner, measured by eye-tracking technology) and attitudinal (online banner irritation) advertising responses are measured as dependent variables. The results indicate that during media multitasking with high task relevance, higher visual attention was obtained for an incongruent (versus congruent) ad banner. When task relevance was low, no such differences were found. This two-way interaction effect was not significant for banner irritation. Further, a significant three-way interaction with task relevance, banner congruity, and banner animation was found on banner irritation but not on visual attention. Concretely, the lowest levels of banner irritation were obtained for a congruent, animated banner in a media multitasking context with high task relevance.

Sleep quality and cortical amyloid-β deposition in postmenopausal women of the Kronos early estrogen prevention study.

Hormone therapy improves sleep in menopausal women and recent data suggest that transdermal 17β-estradiol may reduce the accumulation of cortical amyloid-β. However, how menopausal hormone therapies modify the associations of amyloid-β accumulation with sleep quality is not known. In this study, associations of sleep quality with cortical amyloid-β deposition and cognitive function were assessed in a subset of women who had participated in the Kronos early estrogen prevention study. It was a randomized, placebo-controlled trial in which recently menopausal women (age, 42-58; 5-36 months past menopause) were randomized to (1) oral conjugated equine estrogen (n = 19); (2) transdermal 17β-estradiol (tE2, n = 21); (3) placebo pills and patch (n = 32) for 4 years. Global sleep quality score was calculated using Pittsburgh sleep quality index, cortical amyloid-β deposition was measured with Pittsburgh compound-B positron emission tomography standard uptake value ratio and cognitive function was assessed in four cognitive domains 3 years after completion of trial treatments. Lower global sleep quality score (i.e., better sleep quality) correlated with lower cortical Pittsburgh compound-B standard uptake value ratio only in the tE2 group (r = 0.45, P = 0.047). Better global sleep quality also correlated with higher visual attention and executive function scores in the tE2 group (r = -0.54, P = 0.02) and in the oral conjugated equine estrogen group (r = -0.65, P = 0.005). Menopausal hormone therapies may influence the effects of sleep on cognitive function, specifically, visual attention and executive function. There also appears to be a complex relationship between sleep, menopausal hormone therapies, cortical amyloid-β accumulation and cognitive function, and tE2 formulation may modify the relationship between sleep and amyloid-β accumulation.

Evaluating users\u2019 experiences of electronic prescribing systems in relation to patient safety: a mixed methods study

BackgroundUser interface (UI) design features such as screen layout, density of information, and use of colour may affect the usability of electronic prescribing (EP) systems, with usability problems previously associated with medication errors. To identify how to improve existing systems, our aim was to explore prescribers’ perspectives of UI features of a commercially available EP system, and how these may affect patient safety.MethodsTwo studies were conducted, each including ten participants prescribing a penicillin for a test patient with a penicillin allergy. In study 1, eye-gaze tracking was used as a means to explore visual attention and behaviour during prescribing, followed by a self-reported EP system usability scale. In study 2, a think-aloud method and semi-structured interview were applied to explore participants’ thoughts and views on prescribing, with a focus on UI design and patient safety.ResultsStudy 1 showed high visual attention toward information on allergies and patient information, allergy pop-up alerts, and medication order review and confirmation, with less visual attention on adding medication. The system’s usability was rated ‘below average’. In study 2, participants highlighted EP design features and workflow, including screen layout and information overload as being important for patient safety, benefits of EP systems such as keeping a record of relevant information, and suggestions for improvement in relation to system design (colour, fonts, customization) and patient interaction.ConclusionsSpecific UI design factors were identified that may improve the usability and/or safety of EP systems. It is suggested that eye-gaze tracking and think-aloud methods are used in future experimental research in this area. Limitations include the small sample size; further work should include similar studies on other EP systems.

Drivers’ gap acceptance behaviours at intersections: A driving simulator study to understand the impact of mobile phone visual-manual interactions

Mobile phone use is often considered to be the main source of distraction on the road. Gap acceptance at intersections is a frequent and complex driving task that requires high visual attention from drivers. This study aims to investigate the effect of mobile phone use on the gap acceptance manoeuvre at intersections. Different mobile phone use positions, intersection type, gap size and driver characteristics were considered in the study. A total of 41 licenced drivers drove in an advanced driving simulator in three phone use conditions: baseline (no phone use), using the phone under the steering wheel (covert) and using the phone above the steering wheel (overt). Drivers drove the simulator three times and experienced two intersection types (straight-forward vs. left-turn) and two gap sizes (4 s vs. 7 s) during each drive. A parametric accelerated failure time (AFT) duration model was developed to evaluate the intersection crossing completion time of drivers. The results showed no significant difference of gap acceptance behaviours between the two phone use positions. The distraction task did not affect drivers’ gap acceptance decision, but it increased the crossing completion time by over 10 % compared to baseline. Besides, drivers behaved conservatively at intersections while using a mobile phone, such as adopting a larger deceleration, waiting a longer time, and mainting a larger distance to the front vehicle, etc. However, these compensational behaviours were not helpful in improving the intersection traffic situation regarding both safety and efficiency. Intersection type and gap size were both significant factors of gap acceptance decision and crossing completion time. Additionally, younger drivers were more likely to accept a gap than older drivers, and female drivers spent longer time to cross the intersection than males.

Role of vergence eye movements in the visual recognition of long time duration.

When viewing dichoptic stimuli in long time duration, visual percepts are always the alternation between the left and right eye inputs, while not the combination. This is known as binocular rivalry. An efficient coding theory reported that binocular visual inputs can be combined into binocular summation (S+) and difference (S-) channels in V1 brain area. In this study, we used specially designed stimuli as the previous study, in which monocular inputs caused ambiguous percepts, but S+ and S- channels had unambiguous percepts. We aim to investigate whether the visual percepts alter between S+ and S- channels in long time duration and whether vergence eye movements are involved in the process. To do so, the stimuli were presented in 300-s time duration in a trial, and a binocular eye tracker was used to record eye information. Participants' real-time behavioral responses about the visual percepts and binocular information were recorded simultaneously. The results show there are perceptual flips between S+ and S- channels in both central and long time viewing conditions. More importantly, in central vision there are vergence eye movements before perceptual flips, suggesting the involvement of high level visual attention; the time of a perceptual flip from S+ is shorter than that of a flip from S-, which might be due to different involvements of visual attention, indicating a bias of feedback connection from higher brain areas for visual attention to S+ channel. Since S+ and S- dominated signals can be carried by different types of binocular neurons, our results provide new insights into high level visual attention and binocular neurons in V1 brain area by using specially designed dichoptic stimuli and eye vergence as measuring tools.

Microsaccades Distinguish Looking From Seeing.

Understanding our visual world requires both looking and seeing. Dissociation of these processes can result in the phenomenon of inattentional blindness or ‘looking without seeing‘. Concomitant errors in applied settings can be serious, and even deadly. Current visual data analysis cannot differentiate between just ‘looking‘ and actual processing of visual information, i.e., ‘seeing‘. Differentiation may be possible through the examination of microsaccades; the involuntary, smallmagnitude saccadic eye movements that occur during processed visual fixation. Recent work has suggested that microsaccades are post-attentional biosignals, potentially modulated by task. Specifically, microsaccade rates decrease with increased mental task demand, and increase with growing visual task difficulty. Such findings imply that there are fundamental differences in microsaccadic activity between visual and nonvisual tasks. To evaluate this proposition, we used a high-speed eye tracker to record participants in looking for differences between two images or, doing mental arithmetic, or both tasks in combination. Results showed that microsaccade rate was significantly increased in conditions that require high visual attention, and decreased in conditions that require less visual attention. The results support microsaccadic rate reflecting visual attention, and level of visual information processing. A measure that reflects to what extent and how an operator is processing visual information represents a critical step for the application of sophisticated visual assessment to real world tasks.

How Does the Attitude to Sustainable Food Influence the Perception of Customers at the Point of Sale? - an Eye-Tracking Study

Sustainability is a growing megatrend in our society entailing an increasing importance of sustainable consumption. Consumers associate sustainable products with ecological and regional production including a high credibility. In order to take advantage of this trend manufacturers of sustainable foods must communicate the sustainability of their products via packaging and displays at the point of sale. The objective of this article is to examine how the design of display elements succeeds in conveying sustainability for a new organic juice. In addition, the perception of individual design elements of sustainable products is determined. To this end, a field study was carried out in a supermarket combining eye-tracking technology with a survey of 32 customers. At the entrance, customers were asked to buy a variety of the newly introduced Emslander organic juice, and then participate in the survey. The results demonstrate that customers with a positive attitude towards sustainable food fixate individual display elements referring to sustainability components for longer and remember product features better. Hence, the positive attitude towards sustainable food results in a higher visual attention at the point of sale. These findings provide recommendations for the design of the display.

Parallel learning processes of a visuomotor adaptation task in a changing environment.

During the control of reaching movements, a key contribution of the visual system is the localization of relevant environmental targets. In motor adaptation processes, the visual evaluation of effector motor behavior enables learning from errors, which demands continuous visual attentional focus. However, most current adaptation paradigms include static targets; therefore, when a learning situation develops in a highly variable environment and there is a double demand for visual resources (environment and motor performance), the evolution of learning processes is unknown. In order to understand how learning processes evolve in a variable environment, a video game task was designed in which subjects were asked to manage a 60° counterclockwise-rotated cursor to capture descending targets with initially unpredictable trajectories. During the task, the cursor and eye movements were recorded to dissect visuomotor coordination. We observed that the pursuit of the targets conditioned a predominant and continuous visual inspection of the environment instead of the rotated cursor. As learning progressed, subjects exhibited a linear reduction in directional error and selected a motor strategy based on the degree of reward, which improved the performance. These results suggest that when the environment demands high visual attention, error-based and reinforced motor learning processes are implemented simultaneously, thus enabling efficient predictive behavior.

In the eye of the beholder? An eye-tracking experiment on emergent leadership in team interactions

Integrating evolutionary signaling theory with a social attention approach, we argue that individuals possess a fast, automated mechanism for detecting leadership signals in fellow humans that is reflected in higher visual attention toward emergent leaders compared to non-leaders. To test this notion, we first videotaped meetings of project teams and collected leadership ratings for the team members from three rating sources. Second, we provided 18 naïve observers with 42 brief, muted video clips of the team meetings and analyzed their eye gazing patterns. Observers gazed at emergent leaders more often, and for an average longer duration, than at non-leaders. Gender effects occurred such that male emergent leaders received a higher number of fixations than female emergent leaders. Non-verbal behavior analysis indicated that emergent leaders showed a higher amount of active gestures and less passive facial expressions than non-leaders. We discuss theoretical and methodological directions for emergent leadership research in teams.

Attention modulates specific motor cortical circuits recruited by transcranial magnetic stimulation

Skilled performance and acquisition is dependent upon afferent input to motor cortex. The present study used short-latency afferent inhibition (SAI) to probe how manipulation of sensory afference by attention affects different circuits projecting to pyramidal tract neurons in motor cortex. SAI was assessed in the first dorsal interosseous muscle while participants performed a low or high attention-demanding visual detection task. SAI was evoked by preceding a suprathreshold transcranial magnetic stimulus with electrical stimulation of the median nerve at the wrist. To isolate different afferent intracortical circuits in motor cortex SAI was evoked using either posterior–anterior (PA) or anterior–posterior (PA) monophasic current. In an independent sample, somatosensory processing during the same attention-demanding visual detection tasks was assessed using somatosensory-evoked potentials (SEP) elicited by median nerve stimulation. SAI elicited by AP TMS was reduced under high compared to low visual attention demands. SAI elicited by PA TMS was not affected by visual attention demands. SEPs revealed that the high visual attention load reduced the fronto-central P20-N30 but not the contralateral parietal N20-P25 SEP component. P20-N30 reduction confirmed that the visual attention task altered sensory afference. The current results offer further support that PA and AP TMS recruit different neuronal circuits. AP circuits may be one substrate by which cognitive strategies shape sensorimotor processing during skilled movement by altering sensory processing in premotor areas.

An eye tracking index for the salience estimation in visual stimuli.

Every day we face visual stimuli able to catch our attention, but this aspect becomes crucial if the visual material has the purpose to spread a message aimed at engaging the observer. In this framework, a worthy aspect is how to measure the "visual engagement" produced by visual stimuli exposure. To this purpose, in the present study, employing the eye tracking technique, an index of visual attention (VA) has been proposed, and applied to pictures belonging to antismoking public service announcements, so to investigate the saliency of health-promoting messages in a young sample. The VA index is a non-dimensional index, defined as the ratio between the percentage of the total time spent fixating an area of interest (AOI) weighted on the total time the picture is showed on the screen, and the percentage of the area occupied by the AOI weighted on the total dimension of the picture. It could be predicted that AOI reporting higher VA values will be the ones having more saliency. Three antismoking Public Service Announcements (PSAs) images have been selected for the study and for each of them were identified: i) "picture" (such as a young man with a sarcastic expression depicted while smoking a cigarette, or the image of a lady who underwent a tracheotomy) and ii) "writing" (text of the antismoking message) AOIs. Main results of the analysis revealed that writing AOIs obtained statistically significant higher VA values than visual AOIs (p=0.03), but these held true only for an ineffective PSA, probably because the text was not perceived as pertinent with the surrounding image. On the other hand, an effective PSA obtained higher VA values in response to visual than writing AOIs observation (p=0.02). The VA index appears therefore to represent a useful tool to measure the saliency of visual stimuli elements.

Influences of Visual Attention and Reading Time on Children and Adults

ABSTRACTThis study investigates the relationship between visual attention and reading time using a mobile electroencephalography device. The mobile electroencephalography device uses a single channel dry sensor, which easily measures participants’ attention in the real-world reading environment. The results reveal that age significantly influences visual attention and reading time. Adults’ visual attention and reading time are superior to those of children; furthermore, the visual attention and reading time of adults are positively correlated, indicating that the executive function of attention and reading time increases with age. Regarding gender differences, boys’ visual attention is superior to that of girls, whereas female adults exhibit higher visual attention than male adults. Moreover, multimedia picture books substantially enhance boys’ visual attention, whereas girls exhibit low visual attention. This result indicates that multimedia picture books with sound, light, and animation effects are more appealing to boys and thus enhance boys’ attention.

The role of neurometabolites in emotional processing

ObjectiveTo investigate how brain metabolites, especially glutamate and glutamate to glutamine ratio of pgACC modulate the neural response within these areas and how this affects their function during emotion facial expression matching task.MethodsSeventy healthy volunteers underwent magnetic resonance spectroscopy (MRS) and task functional magnetic resonance imaging (fMRI) in 7 Tesla scanner. PgACC MRS data were obtained using STEAM sequence and analyzed using LCModel.Angry, fearful, and happy facial expressions were presented in an affect-matching block where one of the two facial expressions presented matched the target facial expression. The control condition was form matching. Data were preprocessed and analyzed in SPM 8.ResultsGlutamate to Creatine ratio measured in pgACC positively correlated with BOLD response in the right DLPFC during negative emotional perception (FWE = 0.05) Glutamate to glutamine ratio indicating on-off mechanisms in pgACC positively correlated with BOLD responses in FFA extending to cerebellum cluster (FWE &lt; 0.05).ConclusionThis study indicate that pgACC, baseline metabolism predicts neural response to emotional processing. We conclude that individuals with higher glutamate ratios, an excitatory neurotransmitter, in pgACC during rest might have a better coping mechanism to potential danger indicated by perception of angry or afraid faces.The higher glutamate to glutamine ratio in pgACC indicates a higher turnover of excitatory metabolite glutamate. This mechanism is associated with higher emotional response in fusiform area and cerebellum suggesting higher visual attention towards negative emotions.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Attention Modulates TMS-Locked Alpha Oscillations in the Visual Cortex.

Cortical oscillations, such as 8-12 Hz alpha-band activity, are thought to subserve gating of information processing in the human brain. While most of the supporting evidence is correlational, causal evidence comes from attempts to externally drive ("entrain") these oscillations by transcranial magnetic stimulation (TMS). Indeed, the frequency profile of TMS-evoked potentials (TEPs) closely resembles that of oscillations spontaneously emerging in the same brain region. However, it is unclear whether TMS-locked and spontaneous oscillations are produced by the same neuronal mechanisms. If so, they should react in a similar manner to top-down modulation by endogenous attention. To test this prediction, we assessed the alpha-like EEG response to TMS of the visual cortex during periods of high and low visual attention while participants attended to either the visual or auditory modality in a cross-modal attention task. We observed a TMS-locked local oscillatory alpha response lasting several cycles after TMS (but not after sham stimulation). Importantly, TMS-locked alpha power was suppressed during deployment of visual relative to auditory attention, mirroring spontaneous alpha amplitudes. In addition, the early N40 TEP component, located at the stimulation site, was amplified by visual attention. The extent of attentional modulation for both TMS-locked alpha power and N40 amplitude did depend, with opposite sign, on the individual ability to modulate spontaneous alpha power at the stimulation site. We therefore argue that TMS-locked and spontaneous oscillations are of common neurophysiological origin, whereas the N40 TEP component may serve as an index of current cortical excitability at the time of stimulation.

Vision-related problems among the workers engaged in jewellery manufacturing

Background:American Optometric Association defines Computer Vision Syndrome (CVS) as “complex of eye and vision problems related to near work which are experienced during or related to computer use.” This happens when visual demand of the tasks exceeds the visual ability of the users. Even though problems were initially attributed to computer-related activities subsequently similar problems are also reported while carrying any near point task. Jewellery manufacturing activities involves precision designs, setting the tiny metals and stones which requires high visual attention and mental concentration and are often near point task. It is therefore expected that the workers engaged in jewellery manufacturing may also experience symptoms like CVS.Aim:Keeping the above in mind, this study was taken up (1) To identify the prevalence of symptoms like CVS among the workers of the jewellery manufacturing and compare the same with the workers working at computer workstation and (2) To ascertain whether such symptoms have any permanent vision-related problems.Setting and Design:Case control study.Materials and Methods:The study was carried out in Zaveri Bazaar region and at an IT-enabled organization in Mumbai. The study involved the identification of symptoms of CVS using a questionnaire of Eye Strain Journal, opthalmological check-ups and measurement of Spontaneous Eye Blink rate. The data obtained from the jewellery manufacturing was compared with the data of the subjects engaged in computer work and with the data available in the literature.Statistical Analysis:A comparative inferential statistics was used.Results and Conclusion:Results showed that visual demands of the task carried out in jewellery manufacturing were much higher than that of carried out in computer-related work.
