Industry 4.0 application scenarios, based on the use of Augmented Reality (AR) in combination with wearable devices like Smart Glasses or Head-Mounted Displays (HMD), offer construction companies several opportunities to better deal with the complexity of the construction environment. Despite the given maturity of AR technology, tools or methods to estimate the costs and benefits associated wit...

In this paper, a spatial coherent remote driving system was designed and implemented to operate a telexistence backhoe over a wireless network. Accordingly, we developed a 6 degrees of Freedom (DOF) slave robot that can mimic the human upper body movement; a cockpit with motion tracking system and a Head Mounted Display (HMD) where the operator was provided with a HD720p ultra low latency video...

Different solutions are used on driving simulators to provide visual feedback. In this study, we investigated the influence of projection technology and field of view on drivers‟ performance in a slalom driving task. We tested a head mounted display against a curved projection system on our CyberMotion simulator, based on an anthropomorphic robot arm. The results showed that drivers performed s...

Mobile Augmented Reality (AR) applications are typically deployed either on head mounted displays (HMD) or handheld displays (HHD). This paper explores novel interaction techniques for a combined HHD-HMD hybrid system that builds on the strengths of each type of device. We use the HMD for viewing AR content and a touch screen HHD for interacting with the content. A prototype system was develope...

Efficient motion intent communication is necessary for safe and collaborative work environments with collocated humans and robots. Humans efficiently communicate their motion intent to other humans through gestures, gaze, and social cues. However, robots often have difficulty efficiently communicating their motion intent to humans via these methods. Many existing methods for robot motion intent...

The ability to manipulate objects is fundamental to most virtual reality (VR) applications. A multitude of metaphors have been developed to facilitate object selection and manipulation [1], including virtual hand [2], which remains by far the most popular technique in this category. The utility of the virtual hand depends on the user’s ability to see it. Unfortunately, ensuring this is not alwa...

Concerns about potentially harmful effects on the visual system due to the use of head mounted displays (HMDs) in general, and stereoscopic systems in particular, have been raised in the literature. Most of the concerns were based on studies measuring visual function changes following short-term use of HMDs. This study measured functional changes in binocular vision, accommodation, and resoluti...

Research has shown that spatial disorientation often occurs when pilots transition between real-world visual cues and head-down attitude instruments. Recent studies investigating the opto-kinetic cervical reflex (OKCR) indicate that when pilots transition between these two types of visual cues, they are also transitioning between frames of reference. Limited research has been conducted investig...

The spatio-temporal characteristics of the human visual system vary widely across the visual field. Recently, we have developed a display capable of simulating arbitrary visual fields on high-resolution natural videos in real time by means of a gaze-contingent spatio-temporal filtering [1]. While such a system can also be a useful tool for psychophysical research, our main motivation is to deve...

to increase the degree of detail, mitigate glares and enhance the visibility of the scene in both bright and dim lighting conditions. The proposed operator and its real-time implementation are specially aimed as an aid system for visually impaired people who struggle to manage themselves in environments where illumination is not uniform or changes rapidly. This aid device processes in real-time...
