About

Graduated in Systems and Informatics Engineering at Minho University in 1998. During his PhD he researched in the area of 3D reconstruction from Images divided between Philips Research, Eindhoven, and Minho University, until he concluded in 2006.

He worked in the industry in the field of interactive systems, until he joined FEUP as Invited Assistant Professor in 2009, in the Department of Informatics Engineering (FEUP), to teach and research in the areas of Computer Graphics, Interaction and Game design and development.

He is a collaborator at INESC TEC/INESC Porto since 2011. Currently he is also the director of the Multimedia Masters of University of Porto, and responsible by the Graphics, Interaction and Gaming (GIG) Lab at DEI/FEUP.

Design and Evaluation of Travel and Orientation Techniques for Desk VR

2022 IEEE CONFERENCE ON VIRTUAL REALITY AND 3D USER INTERFACES (VR 2022)

Abstract
Typical VR interactions can be tiring, including standing up, walking, and mid-air gestures. Such interactions result in decreased comfort and session duration compared with traditional non-VR interfaces, which may, in turn, reduce productivity. Nevertheless, current approaches often neglect this aspect, making the VR experience not as promising as it can be. As we see it, desk VR experiences provide the convenience and comfort of a desktop experience and the benefits of VR immersion, being a good compromise between the overall experience and ergonomics. In this work, we explore navigation techniques targeted at desk VR users, using both controllers and a large multi-touch surface. We address travel and orientation techniques independently, considering only continuous approaches for travel as these are better suited for exploration and both continuous and discrete approaches for orientation. Results revealed advantages for a continuous controller-based travel method and a trend for a dragging-based orientation technique. Also, we identified possible trends towards task focus affecting overall cybersickness symptomatology.

Immersive Multimodal and Procedurally-Assisted Creation of VR Environments

Abstract
We present VR Designer, a tool for expediting the creation 3D scenes inside VR. It uses controllers and voice commands to create and manipulate primitives and objects imported from openly available repositories. We use modifiers to accelerate repetitive tasks, resorting to procedural content creation techniques to automate the workflow. The tool allows non-expert users to quickly create scenes for contexts such as training or education. We also conducted a user study to validate VR Designer.

Immersive Adventure Games Development using 360-degree video

Authors
Pinho, F; Nóbrega, R; Rodrigues, R;

Publication
International Conference on Graphics and Interaction, ICGI 2021, Porto, Portugal, November 4-5, 2021

Abstract
Immersive Interactive 360° videos, experienced through Head-Mounted Displays (HMD), constitute a particular case of VR applications for which it is relatively easy to record content nowadays, and that can be explored as a game format. We therefore explore the idea of using live action 360° videos as the basis for immersive adventure games. In particular, we explore possible interactions in immersive adventure games based on 360° videos, in terms of game elements and mechanics, and the player's interface with those. To support this, we developed a browser-based framework for creating such games, and conducted a user study with a game created specifically for that purpose. The results obtained indicate a high level of satisfaction with the chosen control schemes and game mechanics, and suggest that the framework can be used to create this kind of experience.

Point Cloud Interaction and Manipulation in Virtual Reality

Authors
Garrido, D; Rodrigues, R; de Sousa, AA; Jacob, J; Silva, DC;

AIVR 2021: The 5th International Conference on Artificial Intelligence and Virtual Reality, Kumamoto, Japan, July 23 - 25, 2021

Abstract
The use of virtual reality technologies for data visualization and analysis has been an emerging topic of research in the past years. However, one type of data has been left neglected, the point cloud. While some strides have been made in the visualization and analysis of point clouds in immersive environments, these have yet to be used for direct manipulation interactions. It is hypothesized that as with other types of data, bringing direct interactions and 3D visualization to point clouds may increase the ease of performing basic handling tasks. An immersive application for virtual reality HMDs was developed in Unity to help research this hypothesis. It is capable of parsing classified point cloud files with extracted objects and representing them in a virtual environment. Several editing tools were also developed, designed with the HMD controllers in mind. The end result allows the user to perform basic transformative tasks to the point cloud with an ease of use and intuitive feeling unmatched by the traditional desktop-based tools. © 2021 Owner/Author.
