Aggressiveness attributed to violent video game play is typically studied as a function of the content features of the game. However, can interface features of the game also affect aggression? Guided by the General Aggression Model (GAM), we examine the controller type (gun replica vs. mouse) and screen size (large vs. small) as key technological aspects that may affect the state aggression of ...

Visual display systems using fixed screens, including Immersive Projection Technology (IPT) displays, have a merit that they can provide a stable world against the user’s head motion. In spite of this merit, such display systems have not been used for “telexistence in real worlds”, which requires accurate stereoscopic view of live video image. We have proposed a method to realize a lived-video-...

computers are used everywhere from home to work these days, thus the effects on the visual system will be more noticeable every day. problems associated with computer usage are generally known as the computer vision syndrome (cvs).these problems include eye fatigue, irritation ,redness , blurred vision and dry eye. all of these problems have adverse effects on individuals in the long term and r...

Compared to collocated interaction, videoconferencing disrupts the ability to use gaze and gestures to mediate interaction, direct reactions to specific people, and provide a sense of presence for the satellite (i.e., remote) participant. We developed a kinetic videoconferencing proxy with a swiveling display screen to indicate which direction that the satellite participant was looking. Our goa...

There are a number of challenges for researchers in the area of window and screen space management: (1) many systems have been proposed, but little study on people’s window interaction habits exists, (2) users of emerging display systems have different properties and needs than users of single-display systems, yet users might also interact with several different types of systems, and (3) evalua...

Currently available screen and retinal head mounted displays have insufficient field of view to fully exploit many virtual and augmented reality applications. Screen based displays suffer from weight and size restrictions as the image sources, electronics, and viewing optics need to be head mounted. Retinal displays need only the scanning and optical delivery components to be head mounted, but ...

A recent advancement was achieved in the integration and miniaturization of a binocular head-worn projection display (HWPD) conceived for fully mobile users. The devised display, referred to as Mobile HWPD (M-HWPD), offers see-through capability through custom-designed, light-weight projection optics and an integrated commercial-off-the-shelf (COTS) retro-reflective screen to display full color...

OBJECTIVE The purpose of this study was to determine soft-copy image display preferences of brightness, latitude, and detail contrast for neonatal chest computed radiography to establish a baseline for future work on low-dose imaging. CONCLUSION Observers preferred brighter images with higher detail contrast and narrow to middle latitude for soft-copy display compared with the typical screen-...

We report an electro-optic image shifter to enhance the resolution of display devices with a Pancharatnam-Berry phase deflector (PBD). The switching time of our PBD is less than 1 ms. Through synchronizing and computational factorization, we are able to double the display resolution for reducing the screen door effect. Such a thin and lightweight PBD image shifter can be easily integrated into ...

Large high-resolution displays combine the images of multiple smaller display devices to form one large display area. A total resolution that can easily comprise several hundred megapixels makes them suited for the visualization of data sets that could not be perceived entirely on desktop PCs or laptops due to their size. At the same time, user collaboration benefits from an extended screen are...
