A quantitative assessment of intraspecific morphological variation in Gahagan bifaces from the southern Caddo area and central Texas
2019
This investigation aggregates intact or reconstructed Gahagan bifaces from the southern Caddo area and central Texas to test the hypothesis that Gahagan biface morphology differs between the regions. The Gahagan bifaces (n = 102) were scanned, then analysed using a novel landmarking protocol and the tools of geometric morphometrics. Results provide a preview of the significant differences in Gahagan biface morphology expressed between the southern Caddo area and central Texas regions. The size discrepancy represents an inversion of current theoretical constructs that posit a decrease in tool size thought to articulate with an increase in distance from the raw material source. It is posited …
Sieci społecznościowe w ukraińskiej edukacji: blaski i cienie
2018
W artykule przedstawiono koncepcyjne podstawy bezpieczeństwa w zakresie korzystania z sieci społecznościowych w edukacji na Ukrainie. Potwierdzono stanowisko, że tylko z wystarczającym stopniem kształcenia w tym wymiarze, edukacja nabywa nieprzerwanej formy i może skutecznie pełnić funkcję rozwoju aktualnych wartości dla narodu ukraińskiego i innych nacji. Podkreślono ideę potencjalnego wpływu sieci społecznych jako innowacyjnego narzędzia edukacyjnego wpływającego bezpośrednio lub pośrednio na bezpieczeństwo humanitarne państwa ukraińskiego. Wykazano, że wpływ ten jest spowodowany szybkim i dyskretnym rozpowszechnianiem informacji za pośrednictwem sieci społecznościowych, realizowanym zaró…
Lessons Learned Using Theory of Mind Methods to Investigate User Social Awareness in Virtual Role-Play
2009
Theory of mind (ToM) methods were used to investigate children’s interpretations of the social and emotional states of synthetic pedagogical characters, focusing on children’s cognitive and affective empathic responses to characters in bullying scenarios and their social awareness and understanding of the characters’ situations. Although cognitive approaches typically do not consider user social awareness and emotional understanding and their roles in interaction, this is critical for our research on empathic engagement. We present a novel approach focusing on story and character comprehension using concepts from ToM methods to understand children’s interpretations of characters within virt…
Sustainable Value Co-Production and Co-Creation in Virtual Reality: An Exploratory Research on Business-to-Business Interactions
2022
The objective of this study is to identify the environment for business interactions in virtual reality in the value co-production and co-creation process and to understand how such an environment enables the sustainable development of co-creational activities. This paper takes the concepts of value co-production and co-creation and presence and the Actors, Resources, and Activities Model as conceptual references for the exploration of interactions in virtual reality. Using ten in-depth interviews with senior managers, this paper takes an exploratory case analysis perspective. Results show how the sense of presence—level of immersion to which a medium that produces seemingly accurate repres…
A Hybrid Virtual-Augmented Serious Game to Improve Driving Safety Awareness
2018
The use of 3D virtual content and Augmented Reality (AR) in certain applications allows designing tools and serious games that are more attractive to the potential users. Focusing on the area of learning and education, these technologies can be adapted to the requirements of the application that needs to be developed, to the available devices on which they are expected to run and also to the learning content. However, in most applications only a single interaction paradigm and a single visualization mode is used, restricting the potential benefits of the system. In this paper, we propose a software application designed to improve driving safety awareness and learning for both adults and chi…
Multi-Control Virtual Reality Driving Simulator
2019
Immersive technologies (virtual and augmented reality) started gaining a lot of ground over the past few years initially in the video game industry, followed by simulators and finally integrated into many other classic applications. This paper aims to analyze how users respond to using new controlling devices in a scene designed as a driving simulator (race car track). The landscape and the controls are specifically tailored for interactions within immersive environments. In order to understand the capabilities of the experimental application and evaluate the new controls, several tests were conducted. The results are presented from a user experience perspective, emphasizing qualities, side…
Towards a SDN-based architecture for analyzing network traffic in cloud computing infrastructures
2015
Currently, network traffic monitoring tools do not fit well in the monitoring of cloud computing infrastructures. These tools are not integrated with the control plane of the cloud computing stack. This lack of integration causes a deficiency in the handling of the re-usage of IP addresses along virtual machines, a lack of adaption and reaction on highly frequent topology changes, and a lack of accuracy in the metrics gathered for the networking traffic flowing along the cloud infrastructure. The main contribution of this paper is to provide a novel SDN-based architecture to carry out the monitoring of network traffic in cloud infrastructures. The architecture in based on the integration be…
Psychological Influence of Double-Bind Situations in Human-Agent Interaction
2007
This paper presents a new approach to integrate artificial intelligence in virtual environments. The system presented deals in a separated way the visualization and intelligence modules, applying in this last case a distributed approach (multi-agent systems) so that scalable applications may be built. Therefore, it is necessary to define agent architectures that allow agents to be integrated in the VW. Thus, a designer is abstracted from the peculiarities of interacting with a virtual environment. There is a first prototype of the framework using JADE as the supporting multi-agent systems platform.
Virtualization of Remote Devices and Services in Residential Networks
2009
Lately solutions for remote access for residential services have been proposed. However, these solutions require modifications to the service controllers. In addition, remote access adds complexity to the client application. We propose here a solution for decoupling remote access from the client itself with an entity that creates virtual instances of remote services in a local network. Thereby, clients will be able to discover the virtual instance and use it. Moreover, client applications do not need to distinguish between local and remote services hence reducing complexity.
Evaluating the user experience of omnidirectional VR walking simulators
2020
Abstract Omnidirectional treadmills (ODTs) have been traditionally proposed as a promising solution for users’ navigation in large-scale virtual environments. These mechanical devices enable users to perform locomotive motion with 360-deg freedom, while keeping their position fixed in the physical world. However, most locomotion approaches based on omnidirectional treadmills have presented either high acquisition or maintenance costs, being the capabilities of the general public, or a limited reliability. In this paper, we present a comparative usability and acceptance study with real users evaluating the two most common approaches for the development of this type of Virtual Reality (VR) wa…
