A 3D Telepresence system allows users to interact with each other in a virtual, mixed, or augmented reality (VR, MR, AR) environment, creating shared space for collaboration and communication. There are two main methods representing within these environments. Users can be represented either as point cloud reconstruction-based avatars that resemble physical user virtual character-based controlled by tracking the users' body motion. This work compares both techniques identify differences...

When two or more users attempt to collaborate in the same space with Augmented Reality, they often encounter conflicting intentions regarding occupation of working area and self-positioning around such without mutual interference. Reality is a powerful tool for communicating ideas during co-assisting task that requires multi-disciplinary expertise. To relax constraint physical co-location, we propose concept Duplicated where digital copy 3D region interest users' environment reconstructed...

Flight simulators with a physical mock-up are dependent on the aircraft type and have high costs. In order to overcome cost issues, generic virtual reality flight simulator is designed. Virtual buttons used without make independent of type. The classic hand metaphor employed interact objects. This paper examines hand-button interaction in where no haptic feed-back provided. effect collision volume button during determined. It concluded that change within design limits, does not significant...

When users create hand-drawn annotations in Virtual Reality they often reach their physical limits terms of precision, especially if the region to be annotated is small. One intuitive solution employs magnification beyond natural scale. However, scaling whole environment results wrong assumptions about coherence between and virtual space. In this paper, we introduce Mag-noramas, a novel interaction method for selecting extracting interest that user can subsequently scale transform inside Our...

Intensive care units (ICUs) that host patients infected by the SARS-CoV-2 Coronavirus are separated from other units. In regular ICU ward rounds, a number of experts different medical areas and expertise present to discuss situation patient. However, this procedure is contrasting COVID-19 measures such as reduced contact personnel traffic. project, we demonstrate system for mixed reality (MR) teleconsultation support wards (ARTEKMED). Through ARTEKMED, remote can join local 3D reconstructed...

Visuo-haptic augmented reality systems enable users to see and touch digital information that is embedded in the real world. PHANToM haptic devices are often employed provide feedback. Precise co-location of computer-generated graphics stylus necessary a realistic user experience. Previous work has focused on calibration procedures compensate non-linear position error caused by inaccuracies joint angle sensors. In this article we present more complete procedure additionally compensates for...

Current Augmented Reality navigation applications for pedestrians usually do not visualize tracking errors. However, uncertainties can accumulate so that the user is presented with a distorted impression of accuracy. To increase awareness users about potential imperfections at given time, we alter visualization system. We developed four and error concepts used controlled Mixed environment to conduct pilot study. found that, while has improve AR systems, it difficult find suitable...

Marker-based optical outside-in tracking is a mature and robust technology used by many AR, VR motion capture applications. However, in small environments the cameras are often difficult to install. An example scenario ergonomic studies car manufacturing, where of worker needs be tracked spaces such as trunk car. In this paper, we describe how extend volume small, cluttered using flexible wireless form unmodified mobile phones that can quickly installed. Since those not synchronized with...

Current teleconsultation solutions for preclinical emergencies can transmit knowledge from a remote expert to local paramedic using audio and 2D video channels. Such technology lacks precision efficiency medical diagnostic tasks, visual feedback is often missing between participants. We investigate mixed reality 3D solution use, which provides reconstruction of the scene expert, displayed in Virtual Reality. A join virtually as an Augmented Reality avatar. The annotate guide paramedics...

Medical teleconsultation was among the initial use cases for early telepresence research projects since medical treatment often requires timely intervention by highly specialized experts. When remote experts support interventions, a holistic view of surgical site can increase situation awareness and improve team communication. A possible solution is concept immersive telepresence, where users virtually join operating theater that transmitted based on real-time reconstruction local site....

Enabling collaborative telepresence in healthcare, especially surgical procedures, presents a critical challenge. The decompressive craniotomy procedure stands out as particularly complex and time-sensitive. current teleconsultation approach relies on 2D color cameras, often offering only fixed view limited visual capabilities between experts surgeons. However, can be addressed with Mixed Reality immersive technology to potentially enable better consultation of the procedure. We conducted an...

AR systems have been developed for many years now, ranging from consisting of a single sensor and output device to with multitude sensors and/or devices. With the increasing complexity setup, handling different as well necessary calibrations registrations increases accordingly. A much needed (yet missing) area augmented reality applications is support system engineers when they set up maintain an by providing visual guides giving immediate feedback on current quality their calibration...

We describe a mobile augmented reality application that is based on 3D snapshotting using multiple photographs. Optical square markers provide the anchor for reconstructed virtual objects in scene. A novel approach pixel flow highly improves tracking performance. This dual also allows new single-button user interface metaphor moving The development of AR viewer was accompanied by studies confirming chosen approach.

Low-cost mobile mixed reality solutions for head tracking, as well tracking of interaction targets, can be enhanced by multiple inertial measurement units (IMUs). Since microelectro-mechanical systems (MEMS) were introduced, IMUs have become smaller, they need less power and cost less. Yet, any sensor, produce sensor error mitigate the accuracy system. This is particularly case low-cost IMUs. In this poster, we investigate whether joint use three reduce overall error. We present a solution...

In this paper, we propose a solution to ease registrational tasks on users and keep them motivated during long lasting procedures using gamification elements. Augmented Reality (AR) technology appears in many different hardware setups ranging from mobile applications full scale room tracking constructions. Many of which contain non-rigid sensors that require re-registrational maintenance preserve satisfactory capabilities. While important for functioning setup, these can become tiring over...
