For the goal of designing a wearable low vision aid, aspects of both head-mounted display (HMD) design and performance evaluation were integrated into a single study of scanning ability. A head-mounted version of a novel retinal light scanning display known as the virtual retinal display was fabricated for this study. A remote head CCD (charge coupled device) attached approximately at the user’...

The head-mounted display (HMD) is a popular form of virtual display, due to its ability to immerse users visually in virtual environments (VEs). Unfortunately, the user’s virtual experience is compromised by the narrow field of view (FOV) it affords, which is less than half that of normal human vision. This paper explores a solution to some of the problems caused by the narrow FOV, by amplifyin...

Among the most critical issues in the design of immersive virtual environments are those that deal with the problem of technologically induced intersensory conict and one of the results, sensorimotor adaptation. An experiment was conducted to support the design of a prototype see-through, head-mounted display (HMD). When wearing video see-through HMDs in augmented reality systems, subjects see...

Virtual reality (VR) systems are used in a variety of applications within industry, education, public and domestic settings. Research assessing reported symptoms and side effects of using VR systems indicates that these factors combine to influence user experiences of virtual reality induced symptoms and effects (VRISE). Three experiments were conducted to assess prevalence and severity of sick...

Augmented reality (AR) is a technology in which a user’s view of the real world is enhanced or augmented with additional information generated from a computer model. In order to have a working AR system, the see-through display system must be calibrated so that the graphics is properly rendered. The optical see-through systems present an additional challenge because we do not have access to the...

Hardware-based malware detectors (HMDs) are a key emerging technology to build trustworthy computing platforms, especially mobile platforms. Quantifying the efficacy of HMDs against malicious adversaries is thus an important problem. The challenge lies in that real-world malware typically adapts to defenses, evades being run in experimental settings, and hides behind benign applications. Thus, ...

We propose a scheme to recover the eye-contact between multiple users in Shared Mixed Reality Space. The eye-contact in a collaborating mixed reality space is lost as the side effect of wearing head-mounted displays (HMDs). We developed a method to synthesize 3D facial video in order to recover eye-contact which was lost by an HMD. Our method can synthesize facial video with arbitrary posture a...

Augmented Reality (AR) is a technology that merges real-world images with computer-generated virtual objects, superimposes the virtual objects upon the real world, and exhibits them in the view of the users. Mechanical maintenance and repair tasks in industrial environments are prospective domains for AR applications. In this paper a prototype of AR system for training and assisting in maintain...

Augmented Reality is not yet widely used. Even though existing for several decades and said to have the potential to provide an ideal, efficient and intuitive way of presenting information. This is because the realization of such Augmented Reality systems requires to solve many principal problems from various areas. Much progress has been made in solving problems of core technologies, which ena...

In this paper, a finishing system with a mounted abrasive tool is proposed for finishing of metallic molds. The shape of the mounted abrasive tool is a ball-end type. When a metallic mold with curved surface is polished, the orientation of the mounted abrasive tool is not only fixed but also its revolution is locked. The motion of the mounted abrasive tool is feedforwardly controlled based on a...
