Marker Detection

This paper presents a novel mobile serious game, "Space Vision", which uses a hidden-object mechanic with fiducial marker detection to gamify a clinical test of visual acuity - a key marker of childhood eye disease. For Space Vision to become a credible clinical tool that can facilitate the screening and home-monitoring of children's visual acuity, it must be able to sustain player engagement over the extended durations required to detect vision abnormalities. Hence, we pay particular attention to developing effective game characters - a crucial aspect of children's game design. Using an early prototype with 13 school children (aged 5-6 years), we investigate player experiences through a series of evaluation sessions, involving a single one-to-one observational playtest, semi-structured interview, and ideation activity with each child. Thematic analysis of our session video recordings, written observations, and ideation artefacts, found that future game iterations must: increase resonance between players and game characters by providing aesthetic and behavioural customisation, embrace more anthropomorphic styling, better imbue narratives pertaining to children's life scripts, and feature fantasy character powers as a form of self-expression. Meanwhile, greater physical device support and digital incentivisation of body posture and head position are key to improving the reliability of the visual acuity measurement.

Point To Point

Purpose: Development of valid and reliable outcome tools to document social approaches to aphasia therapy and to determine best practice is imperative. The aim of this study is to determine whether the Conversational Interaction Coding Form (CICF; Pimentel & Algeo, 2009) can be applied reliably to the natural conversation of individuals with aphasia in a group setting. Method: Eleven graduate students participated in this study. During a 90-minute training session, participants reviewed and practiced coding with the CICF. Then participants independently completed the CICF using video recordings of individuals with non-fluent and fluent aphasia participating in an aphasia group. Interobserver reliability was computed using matrices representative of the point-to-point agreement or disagreement between each participant's coding and the authors' coding for each measure. Interobserver reliability was defined as 80% or better agreement for each measure. Results: On the whole, the CICF was not applied reliably to the natural conversation of individuals with aphasia in a group setting. Conclusion: In an extensive review of the turns that had high disagreement across participants, the poor reliability was attributed to inadequate rules and definitions and inexperienced coders. Further research is needed to improve the reliability of this potentially useful clinical tool.

The Impact

AimTo assess the impact of deprivation on diabetic retinopathy presentation and related treatment interventions, as observed within the UK hospital eye service.MethodsThis is a multicentre, national diabetic retinopathy database study with anonymised data extraction across 22 centres from an electronic medical record system. The following were the inclusion criteria: all patients with diabetes and a recorded, structured diabetic retinopathy grade. The minimum data set included, for baseline, age and Index of Multiple Deprivation, based on residential postcode; and for all time points, visual acuity, ETDRS grading of retinopathy and maculopathy, and interventions (laser, intravitreal therapies and surgery). The main  outcome measures were (1) visual acuity and binocular visual state, and (2) presence of sight-threatening complications and need for early treatment.Results79 775 patients met the inclusion criteria. Deprivation was associated with later presentation in patients with diabetic eye disease: the OR of being sight-impaired at entry into the hospital eye service (defined as 6/18 to better than 3/60 in the better seeing eye) was 1.29 (95% CI 1.20 to 1.39) for the most deprived decile vs 0.77 (95% CI 0.70 to 0.86) for the least deprived decile; the OR for being severely sight-impaired (3/60 or worse in the better seeing eye) was 1.17 (95% CI 0.90 to 1.55) for the most deprived decile vs 0.88 (95% CI 0.61 to 1.27) for the least deprived decile (reference=fifth decile in all cases). There is also variation in sight-threatening complications at presentation and treatment undertaken: the least deprived deciles had lower chance of having a tractional retinal detachment (OR=0.48 and 0.58 for deciles 9 and 10, 95% CI 0.24 to 0.90 and 0.29 to 1.09, respectively); in terms of accessing treatment, the rate of having a vitrectomy was lowest in the most deprived cohort (OR=0.34, 95% CI 0.19 to 0.58).ConclusionsThis large real-world study suggests that first presentation at a hospital eye clinic with visual loss or sight-threatening diabetic eye disease is associated with deprivation. These initial hospital visits represent the first opportunities to receive treatment and to formally engage with support services. Such patients are more likely to be sight-impaired or severely sight-impaired at presentation, and may need additional resources to engage with the hospital eye services over complex treatment schedules.

Geocaching is a multiplayer outdoor sports game. There is a lack of extensive research on this game, and there is a need for more academic research on this game and its application to other contexts worldwide. There are about 5 million people participating in the geocaching game in 220 different countries worldwide. The geocaching game is interesting because the players create it. The players’ role in game design increases its value in human-centred design research. Digital games are a prevalent form of entertainment in which the purpose of the design is to engage the players. This case study was carried out with 52 Finnish geocachers as an Internet survey. The purpose of this conceptual analysis is to investigate how the geocaching sports game might inform game design by looking at player experiences, devices, and techniques that support problem solving within complex environments. Specifically, this analysis presents a brief overview of the geocaching sports game, its role in popular adventure game design, and an analysis of the underlying players’ experiences and enjoyment as a structure to be used in game design.

(1) Background: To evaluate the characteristics of fluorescein breakup patterns (FBUPs) among patients with dry eye disease (DED) and efficacy of FBUPs as a diagnostic test for DED subgroups. (2) Methods: The study enrolled 449 patients with DED. FBUPs were categorized as follows: area break (AB), line break (LB), spot break (SB), dimple break (DB), and random break (RB). Schirmer value, fluorescein breakup time (FBUT), keratoconjunctival score, DED subgroups and subjective symptoms were examined. (3) Results: LB patients presented with short FBUT and high keratoconjunctival score. AB patients presented with short FBUT, high cornea and keratoconjunctival scores. SB patients were young with short FBUT. DB patients exhibited low keratoconjunctival score. RB patients were young, with long FBUT and low keratoconjunctival scores. Among DED subgroups, LB and AB constituted 74.7% of aqueous-deficiency dry eye (ADDE). SB and DB constituted 42.4% of short FBUT dry eye (short FBUT-DE). Post-test probabilities and positive likelihood ratios for ADDE were 58.7% and 1.63, respectively; those for short FBUT-DE were 46.3% and 2.02, respectively. Patients with SB and AB exhibited significantly severe subjective symptoms than other FBUPs. (4) Conclusions: FBUPs are associated with both objective findings and symptoms of DED and may be a clinical tool for identification of DED subgroups.

PurposeTo determine the prevalence of amblyopia and its association with refraction in Chinese preschool children.MethodsThe Yuhuatai Pediatric Eye Disease Study, a cross-sectional, population-based study, was conducted in children aged 36–48 months in Yuhuatai District, Nanjing, China, in 2015. Visual acuity was measured in 1695 eligible children.ResultsOf the 1695 subjects, manifested amblyopia was detected in 25 children (1.47%, 95% CI 0.90% to 2.05%), including 11 and 14 with bilateral and unilateral amblyopia, respectively. Amblyopia prevalence did not differ by gender (p=0.77). Significant refractive errors were found in 22 (88.0%) of children with amblyopia, and strabismus was found in 6 (24.0%) children with amblyopia. In multivariate analysis, amblyopia was significantly associated with hyperopia (≥+2.00 dioptres (D); OR 8.81, 95% CI 3.27 to 23.69, p<0.0001), astigmatism (≥2.00 D; OR 17.90, 95% CI 6.78 to 47.21, p<0.0001) and anisometropia (≥2.00 D; OR 5.87, 95% CI 1.52 to 22.77, p<0.05).ConclusionsThe prevalence of amblyopia in children 36–48 months old in Eastern China was 1.47%. The refractive error is a major risk factor for amblyopia.

AbstractThe results of orbital decompression for thyroid eye disease are presented in a cohort of 33 patients. It was performed by an external Patterson approach in 21 individuals and in 13 by an endonasal endoscopic approach. The endoscopic approach was entirely comparable in respect of improvement in axial proptosis, giving a mean improvement of 4.4 mm as compared with a mean of 3.8 mm for the external approach, and produced a demonstrable improvement in visual acuity and perception of colour in three individuals, where this was compromised, and was associated with fewer complications.

Beliefs And Attitudes

AbstractDespite the end of colonialism, Zimbabwean rural school teachers still find themselves trapped in the colonial pedagogic practices that undervalue the importance of rural school children's experiential knowledge in science. This article explores the beliefs and attitudes of rural primary teachers towards incorporating Indigenous knowledge and Indigenous teaching practices in science education. A case study of 10 teachers in a rural school in Zimbabwe was conducted using the observation method which was complimented with a semi-structured interview. Twenty video recordings were carried out while the teachers were conducting science lessons. Classroom interactions and communications were vividly captured and analysed, while interviews were conducted after observations to capture explanatory details that may not have been apparent during video recordings. Inductive data analysis focusing on themes relating to teachers' views and practices yielded rich and informative details. Findings indicate that teachers are reluctant to integrate Indigenous knowledge and teaching techniques as pedagogical tools. The attitudes are a result of systemic and institutional expectations on teachers.
