A gaze estimation system is one of the communication methods for severely disabled people who cannot perform gestures and speech. We previously developed an eye tracking method using a compact and light electrooculogram (EOG) signal, but its accuracy is not very high. In the present study, we conducted experiments to investigate the EOG component strongly correlated with the change of eye movem...

Fluoroquinolones (FQs) are extensively used in bacterial keratitis and other intraocular infections. Since eye is constantly exposed to light, incidence of ocular phototoxicity due to commonly used FQs is of great interest for their safe use. Phototoxicity of commonly used FQs (ciprofloxacin, lomefloxacin, pefloxacin, ofloxacin, sparfloxacin and gatifloxacin), has been evaluated by using HET-CA...

Abstract Background: Children suffering from cancer frequently use complementary and alternative medicine (CAM). Most of people do not disclose using CAM to their physicians as they fear to be blamed or prohibited using them. Some of these products may interfere with the conventional remedies. The aim of this study was to investigate the frequency and characteristics of CAM ...

An experiment was conducted on the effect of a prototype see-thru head-mounted display (HMD) on visuo-motor adaptation. When wearing video seethru HMDs in augmented reality systems, subjects see the world around them through a pair of head-mounted video cameras. The study looked at the effects of sensory rearrangement caused by a HMD design that displaces the user’s “virtual” eye position forwa...

We describe the pattern of fixations of subjects looking at figurative and abstract paintings from different artists (Molina, Mondrian, Rembrandt, della Francesca) and at modified versions in which different aspects of these art pieces were altered with simple digital manipulations. We show that the fixations of the subjects followed some general common principles (e.g., being attracted to sali...

We propose a compact design of see-through near-eye display that is dedicated to presbyopia. Our solution is characterized by a plano-convex waveguide, which is essentially an integration of a corrective lens and two volume holograms. Its design rules are set forth in detail, followed by the results and discussion regarding the diffraction efficiency, field of view, modulation transfer function...

background: this study was done to assess the use of traditional/complementary and alternative medicine (tm/cam) during pregnancy and the reasons behind it from the mother’s perspective. materials and methods: in a cross-sectional study, 919 pregnant mothers attending at prenatal care units of governmental health centers recruited through a multistage sampling and completed a self-report questi...

background: multiple sclerosis (ms) is an unpredictable neurological disease leading to severe disability in young adults.  the  majority of ms patients  use  complementary and     alternative medicine  (cam)  as adjunct  to conventional  therapies.  this study  aimed  to  investigate the prevalence  of cam utilization among  iranian patients with ms and their attitude  toward the cam usage. me...
