We present the first observation of stochastic resonance (SR) in the human brain's visual processing area. The novel experimental protocol is to stimulate the right eye with a subthreshold periodic optical signal and the left eye with a noisy one. The stimuli bypass sensory organs and are mixed in the visual cortex. With many noise sources present in the brain, higher brain functions, e.g., per...

This work presents a system for providing ubiquitous visual information to actors in a virtual studio, blue screen, or other mixed reality environment. The Scanning Mirror Projector (ScaMP) system uses steerable projection and head pose estimation to form a new type of ever-present display that projects visual information of a virtual world to the gaze direction of the user. This system allows ...

A retrospective study was made of 314 consecutive cases of traumatic hyphaema in a mixed urban and rural Scottish population. Secondary haemorrhage occurred in 4.1% of cases and was not associated with a worsening of final visual acuity. There were no identifiable risk factors for secondary haemorrhage. Poor visual outcome was in most cases attributable to retinal pathology. The use of antifibr...

∗ This work is supported by National Project and Tsinghua Science Research Foundation. Abstract− In this paper, a visual VHDL integrated design environment VIDE for high level design is presented. In VIDE, there are several graphical and textual mixed design entry tools (VDES) and a graphical objectoriented debugger (VDBG). VDES consists of several diagram editors and a visual text editor, whil...

METHODS A retrospective study on medical records of patients who had undergone macular hole surgery under local anesthesia. Funduscopic examination of macular hole had been performed and all other diseases with deterioration of visual acuity eliminated. Surgery was performed under retrobulbar local anesthesia, using 2 ml of 2% lidocaine mixed with 3 ml bupivacaine in one syringe. Vitreous tampo...

background: along with the rapid growth of technology its related tools such as computer, monitors and video display terminals (vdts) grow as well. based on the studies, the most common complaint reported is of the vdt users. methods: this study attempts to design a proper tool to assess the visual fatigue of the vdt users. first draft of the questionnaire was prepared after a thorough study on...

purpose : to compare visual quality in patients receiving alcon acrysof restor multifocal versus acrysof sa60at monofocal intraocular lenses (iol) methods : in this interventional study, patients with senile cataract undergoing surgery were enrolled. the age of the patients ranged between 40 and 85 years, and their potential preoperative vision was 20/30 or better. in all patients phacoemulsifi...

PURPOSE To investigate visual field changes after vitrectomy for macular diseases in glaucomatous eyes. METHODS A retrospective review of 54 eyes from 54 patients with glaucoma, who underwent vitrectomy for epiretinal membrane (ERM; 42 eyes) or macular hole (MH; 12 eyes). Standard automated perimetry (Humphrey visual field 24-2 program) was performed and analyzed preoperatively and twice post...

abstractthe aim of intercultural translation is to communicate. communication is acted via verbal as well as visual means. the interaction of verbal and visual means of communication makes a set of complex situations which demand special attention in translation. one context in which the interaction of visual and verbal elements gets vital importance is children’s picture books. color is an int...
