BACKGROUND Prolonged time of computer use increased the prevalence of ocular problems including eyestrain, tired eyes, irritation, redness, blurred vision, and double vision, collectively referred to as computer vision syndrome. Approximately 70 percent of computer users have vision-related problems. To design the effective screen intervention for preventing or improving computer vision syndrome, we must understand the effective interfaces of computer-based intervention (CBI). OBJECTIVE In this study, we aim to explore the interface elements of computer-based intervention for computer vision syndrome to set design guidelines based on pros/cons of each interface element. METHODS We conducted iterative user study to achieve our research goal. First, we conducted workshop to evaluate overall interface elements that are included in the previous systems for computer vision syndrome (N=7). Second, we designed and deployed our prototype LiquidEye with the multiple interface options to the users in the wild (N=11). Participants used LiquidEye for 14 days and during these period, we collected participants’ daily log (N=680). Also, we conducted pre and post survey and post-hoc interviews to explore how each interface element affects system acceptability. RESULTS We have collected 19 interface elements for designing intervention system for CVS from the workshop, then, deployed our first prototype LiquidEye. After deployment of LiquidEye, we conducted multiple regression analysis with the user data log to analyze significant elements affecting user participation of the LiquidEye. The significant elements include instruction page of eye rest strategy (P<.05), goal setting of resting period (P<.01), compliment page after user complete the resting (P<.0.001), middle-size popup window(P<.05), and symptom-like visual affect that alarms eye resting time (P<.0.005). CONCLUSIONS We suggest design implications to consider when designing CBI for computer vision syndrome. The sophisticated design of the customizing interface can make it possible for users to use the system more interactively which results in higher engagement and management of eye condition. There are important technical challenges still to address, but given the fact that this study has been able to sort out various factors related to computer-based intervention, it is expected to contribute greatly to the research of various CBI designs in the future.

Background Prolonged time of computer use increases the prevalence of ocular problems, including eye strain, tired eyes, irritation, redness, blurred vision, and double vision, which are collectively referred to as computer vision syndrome (CVS). Approximately 70% of computer users have vision-related problems. For these reasons, properly designed interventions for users with CVS are required. To design an effective screen intervention for preventing or improving CVS, we must understand the effective interfaces of computer-based interventions. Objective In this study, we aimed to explore the interface elements of computer-based interventions for CVS to set design guidelines based on the pros and cons of each interface element. Methods We conducted an iterative user study to achieve our research objective. First, we conducted a workshop to evaluate the overall interface elements that were included in previous systems for CVS (n=7). Through the workshop, participants evaluated existing interface elements. Based on the evaluation results, we eliminated the elements that negatively affect intervention outcomes. Second, we designed our prototype system LiquidEye that includes multiple interface options (n=11). Interface options included interface elements that were positively evaluated in the workshop study. Lastly, we deployed LiquidEye in the real world to see how the included elements affected the intervention outcomes. Participants used LiquidEye for 14 days, and during this period, we collected participants’ daily logs (n=680). Additionally, we conducted prestudy and poststudy surveys, and poststudy interviews to explore how each interface element affects participation in the system. Results User data logs collected from the 14 days of deployment were analyzed with multiple regression analysis to explore the interface elements affecting user participation in the intervention (LiquidEye). Statistically significant elements were the instruction page of the eye resting strategy (P=.01), goal setting of the resting period (P=.009), compliment feedback after completing resting (P<.001), a mid-size popup window (P=.02), and CVS symptom-like effects (P=.004). Conclusions Based on the study results, we suggested design implications to consider when designing computer-based interventions for CVS. The sophisticated design of the customization interface can make it possible for users to use the system more interactively, which can result in higher engagement in managing eye conditions. There are important technical challenges that still need to be addressed, but given the fact that this study was able to clarify the various factors related to computer-based interventions, the findings are expected to contribute greatly to the research of various computer-based intervention designs in the future.

Computer Vision Syndrome is the new nomenclature to the visual, ocular, and systemic symptoms arising due to the long time and improper working on the computer. Computer Vision Syndrome is a repetitive strain disorder as defined by the American Optometric. With progressive increase in the usage of computers, the term Repeated Stress Injury has found a place in contemporary medical science. The ocular complaints experienced by computer users typically include eyestrain, eye fatigue, burning sensations, irritation, redness, blurred vision, and dry eyes, among others. This group of symptoms is called Asthenopia. The incidence of Computer Vision Syndrome is as high as 50% to 90% among the employees of computer occupation. The causes for the inefficiencies and the visual symptoms are a combination of individual visual problems and poor office ergonomics. Material & Methods: In this clinical study on CVS, 60 patients were registered from Shalakya tantra OPD, and all of them completed the treatment. In Group A, 30 patients were prescribed Abhijeet Taila for Pratimarsha Nasya and in Group B, 30 patients were prescribed Haritaki Modak tablets internally and Abhijeet Taila for Pratimarsha Nasya. Results: In total, 20% and 33.33% patients got completely cured in Group A and B respectively. Discussion: Both the drugs were effective in managing the condition, but it was observed they were more effective when given together. Multi-centric studies with larger sample size on the same drugs should be carried out to evaluate the effect of the drugs and, also so that the observations can be noted well and can be better suggested.

In the present era, the full computerization of a country is necessary for the progress. The present era can be defined as “Computer Age”. It has seems that the work at the computer is very intensive & most tiring therefore countries like Germany has included computer operational work in the list of the 40 most harmful trades for the health & restricted work at the computer should not exceed 50% of the working time. In the developing countries like India where the remuneration for the work is far from satisfactory & the young generation is aspiring for more material gains which necessitate them to work overtime or have part-time jobs in addition to their legitimate work. This situation adds up to the works with the computer which badly affects their health. Computer Vision Syndrome (CVS) is the complex of eye and vision problems related to near work which are experienced during or related to computer use. CVS is characterized by visual symptoms which result from interaction with a computer display or its environment. In most cases, symptoms occur because the visual demands of the task exceed the visual abilities of the individual to comfortably perform the task. In CVS following Signs & Symptoms occurs.they are Presence of excessive debris & mucous strands in the tear film., Reduced or absence of marginal tear strip.Lusterless ocular surface - xerosis.,Lid Dry & Rough touch. And Symptoms are Itching, Burning sensation, Blurred vision, Dryness of eyes, Redness of eyes, Pricking Pain. , Foreign body Sensation, Difficulty in opening & closing the lids.For the study, we have taken Triphala Ghrita Tarpan for 7 days in three consecutive months for 30 patients in treated group and in controlled group eye exercises given like palming, eye movements for 7days in three consecutive months for 30 patients.The results are very much satisfactory in the treated group as compared to the controlled group.The details will be given in detail in full research paper.

Computer vision syndrome (CVS) is a set of visual, ocular, and musculoskeletal symptoms that result from long-term computer use. These symptoms include eyestrain, dry eyes, burning, pain, redness, blurred vision, etc, which increase with the duration of computer use. Currently, with the closure of schools and universities due to the continued COVID19 pandemic many universities have taken the process of online education courses and the use of mobile phones, tablets، computer monitors and e-readers is increasing day by day. CVS not only reduces study and learning quality and productivity of the students, but it also has a high economic burden by increasing musculoskeletal injuries and ophthalmologist visits due to visual and ocular symptoms. With the expansion of online education programs, it is necessary for students to be aware of these complications, as well as to teach them appropriate strategies to control and prevent these harmful effects of computers.

As mobile robots experience increased commercialization, development of intuitive interfaces for human-robot interaction gains paramount importance to promote pervasive adoption of such robots in society. Although smart devices may be useful to operate robots, prior research has not fully investigated the appropriateness of various interaction elements (e.g., touch, gestures, sensors, etc.) to render an effective human-robot interface. This paper provides overviews of a mobile manipulator and a tablet-based application to operate the mobile manipulator. In particular, a mobile manipulator is designed to navigate an obstacle course and to pick and place objects around the course, all under the control of a human operator who uses a tablet-based application. The tablet application provides the user live videos that are captured and streamed by a camera onboard the robot and an overhead camera. In addition, to remotely operate the mobile manipulator, the tablet application provides the user a menu of four interface element options, including, virtual buttons, virtual joysticks, touchscreen gesture, and tilting the device. To evaluate the intuitiveness of the four interface elements for operating the mobile manipulator, a user study is conducted in which participants’ performance is monitored as they operate the mobile manipulator using the designed interfaces. The analysis of the user study shows that the tablet-based application allows even non-experienced users to operate the mobile manipulator without the need for extensive training.
