Real-Time Hand Pose Recognition Based on a Neural Network Using Microsoft Kinect

2013

The Microsoft Kinect sensor is largely used to detect and recognize body gestures and layout with enough reliability, accuracy and precision in a quite simple way. However, the pretty low resolution of the optical sensors does not allow the device to detect gestures of body parts, such as the fingers of a hand, with the same straightforwardness. Given the clear application of this technology to the field of the user interaction within immersive multimedia environments, there is the actual need to have a reliable and effective method to detect the pose of some body parts. In this paper we propose a method based on a neural network to detect in real time the hand pose, to recognize whether it…

Multimodal virtual navigation of a cultural heritage site: The medieval ceiling of Steri in Palermo

2009

The advance of information technology has enabled in recent years new fruition scenarios for cultural heritage sites. Multidisciplinary approaches integrate survey techniques with multimodal interfaces to allow enhanced fruition for larger group of users. In this paper we propose a multimodal interface to a virtual representation of a medieval ceiling, built in the XIV century, which covers the “Sala Magna” of Steri, the historical headquarters of the University of Palermo, in Italy. This research deals with the definition of a process for the integration of surveying techniques, modelling processes and communication technologies for the documentation of such artifacts. This is a two-stage …

A Pipeline for the Implementation of Immersive Experience in Cultural Heritage Sites in Sicily

2022

Modern digital technologies allow potentially to explore Cultural Heritage sites in immersive virtual environments. This is surely an advantage for the users that can better experiment and understand a specific site, also before a real visit. This specific approach has gained increasing attention during the extreme conditions of the recent COVID-19 pandemic. In this work, we present the processes that lead to the implementation of an immersive app for different kinds of low and high cost devices, which have been attained in the context of the 3dLab-Sicilia project. 3dLab-Sicilia’s main objective is to sponsor the creation, development, and validation of a sustainable infrastructure that int…

The ALSWEB Framework: A Web-based Framework for the Linguistic Atlas of Sicily Project

2011

In this work the ALSWEB framework is presented. The ALSWEB is a virtual linguistic laboratory for linguistic research developed as a web application. The purpose of the framework is to model the entire process regarding the different steps of data acquisition, data transformation, information acquisition from different data and research hypotheses verification in the ALS (Linguistic Atlas of Sicily) project. The nature of the ALS research involves different type of data. The socio-linguistic researcher that is the main actor of the proposed framework has to acquire information in many formats: multimedia data, audio data, question-answer (textual) from particular questionnaires. In this wor…

ARCHEOLOGIA VIRTUALE A SEPPANNIBALE: LA RESTITUZIONE 3D DELLA CHIESA

2011

Virtual Reality applications, such as 3D modelling for exemple, has lately joined research, first with popular teaching role by realizing ideal reconstructions of monuments, cities, landscapes and so on, and only quite recently with the aim of increasing knowledge. Computer Graphics integrated methodologies represent, particularly in archaeology, architecture and field drawing, an update of traditional studies on ancient monuments.

Cognitive rehabilitation of schizophrenia through NeuroVr training.

2013

Cognitive difficulties are prevalent in people with diagnosis of schizophrenia and are associated with poor long-term functioning. In particular, memory, selective, divided and sustained attention and executive functions are altered by this disease. We used a Virtual Reality environment (developed via the NeuroVr2.0 software) for the rehabilitation of shifting, sustained attention and action planning functions using tasks reminiscent of daily life tasks. Test and retest showed significant differences in the assessed cognitive dimensions.

Virtual reality environments to rehabilitation attention deficits in schizophrenic patients

2016

Abstract. Cognitive dysfunction is a core feature of schizophrenia. Patients with schizophrenia shown perform poorly on tasks that require vigilance or sustained attention. Patients with more pronounced attention deficits are least likely to acquire skills in psychosocial programs as the attention problems makes it difficult for them to process the information given in groups, and they may not be able to sustain attention for the session duration. The study aimed to develop a Virtual Reality cognitive training to improve the selective, divide and sustained attention. Specifically, we developed, via the NeuroVr 2.0 software, three different virtual environments with the hierarchical sequence…
