Educ-AR: A tool for assist the creation of augmented reality content for education

The article presents a software tool that provides an easy way to creates augmented reality presentations. This tool allows the user to authoring his own presentation without a help of a programmer. The tool is supported by a web portal that provides the account creation and a database to storage the presentations created by the users.

Interperception on Shared Virtual Environments

In this work we introduces the concept of interdimensional virtual environments and proposes to it creation an architecture based on the client-server model. Our architecture allows the users with different resources sharing the same environment in a transparent way, same that users are connected by a different graphical interfaces. This interdimensionality provides by the system is possible thanks to the use of a component in the serving side that if put in charge to carry through, when necessary, the transformation of the messages of a dimension for another one, removing or adding indispensable information to the different customers of the system

Development of a low cost dataglove based on arduino for virtual reality applications

This article describes the first steps on the development of a low cost dataglove based on the Arduino Uno microprocessor. The glove is designed for use in virtual reality systems and is integrated into a suite of applications. This article also presents a set of preliminary results obtained with the glove and discuss about the use of the glove to control a video game application for rehabilitation of stroke patients.

A path editor for virtual museum guides

In this work we propose a tool for path generation of animated beings (devices as robots, and humans) in a virtual environment. The focus of this application is the creation and edition of this path for guided tour in virtual museum. To validate this approach we present a virtual exhibition were a virtual guide following the generated path and conduces the virtual visitors in the museum.

GTMV: Virtual museum authoring systems

In this work we propose a system that has joined the multi-user system paradigm and the easy-to-use authoring tools for the development of virtual museums through the Web. Our system provides an interface for authoring and another interface for navigation. The authoring interface is used by the curator and has tools for building and editing museums. The navigator interface is used by visitors to interact with the museum including its objects and other users.

PHYS.IO: Wearable hand tracking device

This paper describes the development of a human computer interface focused in detect hand movements and gestures and apply this data into a 3D environment, all this running based on an Android mobile device.

Indirect group interaction in interpeceptives virtual environments

This paper proposes a component that can capture a variety of user movements and use that to create information and interaction with computational applications, like electronic games and Interactive Digital TV Programs in a pervasive approach. Some techniques and systems get information from the user, like thoughts and actions, to provide extra functionality but that is done for one user at each time. The component proposed here bases itself on observing the user, thus it is able to detect his thoughts and feelings based on his actions, providing ways for users to interact seamlessly and for the system to change its outputs and states based on whatever the users are doing. Besides that, systems might be created to support multiple inputs from groups of users providing a whole new range of outputs. The events generated through these users observation are referred here as Indirect Group Interaction.

ITV-telearch an architecture for enabling device telecontrol and sensor data access over IDTV systems

Our work provides the specification and implementation of a communication mechanism between broadcast content viewers and interaction devices or sensors placed on the scenario of a live video show. This solution was designed using middleware based architecture and interconnects the devices and sensors of a broadcast program environment in a device network. By using the proposed architecture, the viewers will be able to see the real world interaction devices and control them through interactive applications using specific APIs to each broadcast system. So this approach is able to manage the devices in the network despite of the physical layer used to communicate, allowing them to communicate to each other and to be controlled by external applications. Afterwards, by using the architecture, we can allow viewers to control or access data from entities which compound the network through distributed communication processes and control applications. In order to validate our work we present a test scenario where a mobile robot with a set of sensors is added to our architecture and controlled by the viewers.

Virtual multiverse: Interperception in multiple virtual universes

In this paper we propose a design and implementation of a collaborative virtual environment that supports virtual multiverse. With this, we are creating an infra-structure that allows the insertion of all possible and imaginable virtual worlds, allowing the coexistence of these different virtual worlds in a same application. On this system, the users can visit many different words using a same avatar.

The H-N2N framework: towards providing interperception in massive applications

We propose a framework with a flexible architecture that have been designed and implemented for collaborative interaction of users, to be applied in massive applications through the Web. We introduce the concept of interperception and use technologies as massive virtual environments and teleoperation for the creation of environments (mixing virtual and real ones) in order to promote accessibility and transparency in the interaction between people, and between people and animate devices (such as robots) through the Web. Experiments with massive games, with interactive applications in digital television, with users and robots interacting in virtual and real versions of museums and cultural centers are presented to validate our proposal.
