The Scanner-Display system, called SCAD, is a device for communicating between computers and pictures. In its present form it can accept transparencies, measure the transmission at various points on the transparency, and convert this to a digital number. It can also accept digital data and produce pictures from it. The device is a transducer between digital computers and pictures. SCAD can be o...

Quantitative assessment is made of using two display techniques, providing two different levels of depth perception, in conjunction with a haptic device for manipulating 3D objects in virtual environments. The two display techniques are 2D display, and interactive 3D stereoscopic virtual holography display on a zSpace tablet. Experiments were conducted, by several users of different ages and co...

This paper starts by examining the issues related to integrating real and virtual objects in a virtual reality environment. In particular it discusses the problems of occlusion, shadows and specular reflections. As an alternative to immersive virtual reality, this paper considers existing 3-D display technologies . It then discusses the limitations of these approaches and presents a thought exp...

Millions of people worldwide need glasses or contact lenses to see or read properly. We introduce a computational display technology that predistorts the presented content for an observer, so that the target image is perceived without the need for eyewear. By designing optics in concert with prefiltering algorithms, the proposed display architecture achieves significantly higher resolution and ...

Owing to the limited spatio-temporal resolution of display devices, dynamic holographic three-dimensional displays suffer from a critical trade-off between the display size and the visual angle. Here we show a projection-type holographic three-dimensional display, in which a digitally designed holographic optical element and a digital holographic projection technique are combined to increase bo...

A preliminary study was conducted to investigate the use of visual flow cues as an aid to ground and vertical drift awareness during helicopter flight and targeting while using night vision goggles (NVG's). Three displays were compared: 1) NVG display: simulated NVG image of cockpit and external environment; 2) Overlay display: NVG image with an overlay of a flow cue field and a surrounding wir...

Ultimately, a display device should be capable of reproducing the visual effects that are produced by reality. In this paper we introduce an autostereoscopic display that uses a scalable array of digital light projectors and a projection screen augmented with microlenses to simulate a light field for a given three-dimensional scene. Physical objects emit or reflect light in all directions to cr...

Haptic devices are applied as masters to provide force displays for telemedicinal robots. Gravity compensation has been proven be crucial the accuracy and capability of displays, which critical haptic assist operators. Therefore, existing method suffers from an unsatisfactory effect, a complex implementation, low efficiency. In this paper, approach combining active passive gravity is proposed i...

Introduction An important part of color reproduction is the rendering of colors onto display devices [1], where the colors may be spot colors (e.g., tints) or the colors of a digitized photograph. Display devices, such as monitors and printers, are capable of showing only a subset of all perceivable colors; this subset is called the device color gamut. Colors subjected to a reproduction system ...
