Objective: The main purpose of this study is to evaluate the visual angle and ambient illumination effects on visual fatigue and performances while viewing from a projected screen for 40 minutes. Methods: Visual angle (16, 24 and 48 min arc of Chinese character height) and ambient illumination (200 and 750 lux) were the independent variables in this study. Change in critical flicker frequency (...

In multimodal integration and sensorimotor transformation areas of posterior parietal cortex (PPC), neural responses often appear encoded in spatial reference frames that are intermediate to the intrinsic sensory reference frames, e.g., eye-centred for visual or head-centred for auditory stimulation. Many sensory responses in these areas are also modulated by direction of gaze. We demonstrate t...

Reciprocal shading for mixed reality aims to integrate virtual objects into real environments in a way that they are in the ideal case indistinguishable from real objects. It is therefore an attractive technology for architectural visualizations, product visualizations and for cultural heritage sites, where virtual objects should be seamlessly merged with real ones. Due to the improved performa...

This paper distinguishes between parallel and integrated mixed methods research approaches. Barriers to integrated mixed methods approaches in gerontological research are discussed and critiqued. The author presents examples of mixed methods gerontological research to illustrate approaches to data integration at the levels of data analysis, interpretation, and research reporting. As a summary o...

Mixed noise expulsion from characteristic images is a testing errand since the noise dispersion normally does not have a parametric model and has an overwhelming tail. One sort of the mixed noise is Additive White Gaussian Noise (AWGN) coupled with Impulse Noise (IN).However, first catch the region of IN pixels and afterward evacuate the mixed noise. On the other hand, such techniques have a te...
