OBJECTIVE Annual diabetic eye screening has been implemented in England since 2008. This study aimed to estimate changes in the detection of retinopathy in the first 4 years of the program. RESEARCH DESIGN AND METHODS Participants included 32,340 patients with type 2 diabetes resident in three London boroughs with one or more screening records between 2008 and 2011. Data for 87,570 digital im...

In modern societies people tend to spend more time in front of computer screens than outdoors. Along with an increasing degree of realism displayed in digital environments, simulated weather appears more and more realistic and more often implemented in digital environments. Research has found that the actual weather influences behavior and mood. In this paper we experimentally examine the effec...

Introduction: Floaters, or particles that appear to float in the visual field, are often subjective complaints cause disruptive sensations vision. Eye strain, which is a common symptom associated with prolonged use of digital screens, can lead other disorders. However, there limited research examining relationship between eye strain and floaters. This study aimed evaluate eyestrain occurrence f...

This paper describes the Facilitation Tool, a tool built to untangle two problems that we find in current Group Decision Support Systems. If we want to allow facilitators manage such systems with success, then a planning functionality more detailed than the currently available is necessary. We also found very limited support to remote facilitation. Several notions concerning decision-making and...

Movers and Shakers is a tablet-based serious game that explores how subversive game design can foster meaningful conversational conflict beyond outside the game’s digital screens. This twoplayer strategy puzzle was developed at the Singapore-MIT GAMBIT Game Lab and is used as a research tool to explore novel challenges in multiplayer serious games. The project provides insights into the afforda...

Phase errors introduced in the object beam of a digital hologram degrade the image quality of the object. We present computer simulations showing the effect of multiple planes of phase errors in the propagation path. By using a nonlinear optimization technique to maximize sharpness metrics, we show results that account for aberrations in multiple planes and correct anisoplanatic blur. This pape...

Nevertheless, in many of the institutions that have already introduced digital acquisition techniques, the working methods have remained essentially conventional. Cassettes are still used, although they now contain storage screens rather than screen-film combinations. The image is still assessed as a (laser) film on a lightbox. In fact, the complete working routine has not changed significantly...
