“…This is in line with similar studies that found neck pain to be a common symptom among computer users, ranging from 19% to 70% ( 11 – 13 , 28 , 29 ). Touch screen devices, according to Kargar et al, necessitate more hand and head movements, resulting in arm/neck pain ( 30 ). Another study found that 68% of participants experienced musculoskeletal pain as a result of using touch screens, with neck pain and upper shoulder pain reported at 84.6% and 65.4 %, respectively, due to unnatural sitting positions without adequate back support ( 31 ).…”

Repetitive prolonged use of digital devices without regular breaks has detrimental effects on ocular health and quality of vision. Individuals with chronic eye problems and refractive errors are at higher risk of developing digital eye strain (DES). Correction of refractive errors, adopting healthy practices will reduce its risk. The survey examined the effect of prolonged lockdown on the development and increased severity of digital eye strain (DES) symptoms among the general population. An online survey was conducted in March 2020 on social media platforms in Jordan. Data from 1,460 responders were analyzed. About half of the respondents were between 30–49 years, 28.4% were retired, 21% had chronic systemic illness, and 23% reported chronic eye problems. A rise in the use of digital devices during lockdown was reported by 957 participants, with 33% of them used digital devices more than 4 h a day. The most common symptoms before and during lockdown were headache and neck / shoulder pain have the highest associations (X2 = 280.0, 271.3, df = 4, p < 0.001 respectively). Female gender, existence of chronic eye problems and systemic diseases, and duration of using digital devices were found to be statistically significant factors associated with increasing severity of eye symptoms during lockdown. Not taking enough regular breaks from digital devices showed significant association with blurred vision at distance and near (X2 = 13.03, 10.74, df = 4, P = 0.011, 0.03, respectively). People with chronic eye problems and increased time using devices during lockdown developed new eye complaints three times more than before the lockdown and males were two times more likely than females to have more severe eye symptoms.

Purpose: the study examined the effect of prolonged lockdown on the development and increased severity of digital eye strain (DES) symptoms among the general population. Methods: An online survey was conducted in March 2020 on social media platforms in Jordan. The questionnaire consisted of questions related to demographic characteristics, past medical and ocular history, frequency of using digital devices before and during lockdown, and the emergence and severity of DES symptoms.Results: Data from 1,460 responders were analyzed. About half of the respondents were between 30- 49 years, 28.4 % were retired, 21% had chronic systemic illness, and 23% reported chronic eye problems. A rise in the use of digital devices during lockdown was reported by 957 participants, with 33% of them used digital devices more than 4 hours a day. The most common symptoms before and during lockdown were neck and shoulder pain, which revealed the most significant association (X2 201.61, p 0.000). Female gender, existence of chronic eye problems and systemic diseases, and duration of using digital devices were found to be statistically significant factors associated with increasing severity of eye symptoms during lockdown. Regarding developing new eye complaints during the lockdown, only taking regular breaks was not significant (p 0.336). People with chronic eye problems and increased time using devices during lockdown developed new eye complaints three times more than before the lockdown and males were two times more likely than females to have more severe eye symptoms.Conclusion: The majority of the population developed new DES symptoms due to the lockdown. Public awareness of healthy practices and ergonomic use of digital devices is recommended.

“…Varying response times of the touch display and the keyboard, possibly also differences of input and output delays that may originate in the manner of implementation, including the toolkits being used, may have an impact here. In addition, there are human factors to consider (46), and these may for example be related to differences in posture between using a keyboard or a touch interface when interacting with the app (47), or a user's perception of tactile effects when using the different input methods (46,48). For the test order, with average latency values decreasing with each additional test, it seems sensible to conclude that faster response times may be due to increasing practice.…”

ObjectiveTo determine whether a framework-based approach for mobile apps is appropriate for the implementation of psychological testing, and equivalent to established methods.MethodsApple's ResearchKit was used for implementing native implicit association test methods (IAT), and an exemplary app was developed to examine users' implicit attitudes toward overweight or thin individuals. For comparison, a web-based IAT app, based on code provided by Project Implicit, was used. Adult volunteers were asked to test both versions on an iPad with touch as well as keyboard input (altogether four tests per participant, random order). Latency values were recorded and used to calculate parameters relevant to the implicit setting. Measurements were analyzed with respect to app type and input method, as well as test order (ANOVA and χ2 tests).ResultsFifty-one datasets were acquired (female, n = 21; male, n = 30, average age 35 ± 4.66 years). Test order and combination of app type and input method influenced the latency values significantly (both P<0.001). This was not mirrored for the D scores or average number of errors vs. app type combined with input method (D scores: P = 0.66; number of errors: P = 0.733) or test order (D scores: P = 0.096; number of errors: P = 0.85). Post-hoc power analysis of the linear ANOVA showed 0.8 by f2=0.25, with α = 0.05 and 4 predictors.ConclusionsThe results suggest that a native mobile implementation of the IAT may be comparable to established implementations. The validity of the acquired measurements seems to depend on the properties of the chosen test rather than the specifics of the chosen platform or input method.
