Designing a mobile collaborative system for navigating and reviewing oil industry cad models

Publication . Noronha, Hildegardo; Campos, Pedro; Jorge, Joaquim; Araújo, Bruno de; Soares, Luciano; Raposo, Alberto

In this paper, we describe an industrial experience with the creation of a new product for collaboratively navigating and reviewing 3D engineering models, applied to the oil industry. Together with professional oil industry engineers from a large oil company, a team of HCI researchers per formed task analysis and storyboards, designed, imple mented and qualitatively evaluated a prototype that com bines the power of mobility brought by tablets with new navigation modes that employ every sensor present in the tablet to deliver a better experience. The system was the target of a qualitative assessment made by architects and oil industry engineering experts. Lessons learned are valuable, both in terms of performance and experience design, issues that necessarily arise when creating new collaborative vir tual reality systems

On the usage of different work analysis methods for collaborative review of large scale 3D CAD models

Publication . Campos, Pedro; Noronha, Hildegardo

Human work interaction design is an emerging discipline that aims to encourage empirical studies and conceptualizations of the interaction among humans, their variegated social contexts and the technology they use both with in and across these contexts. In this paper we describe and elaborate around the usage of different work analysis methods in a complex, real world work do main: collaborative review of large-scale 3D engineering models. The analysis is based on (i) input from experts in the oil platform engineering field, (ii) pre vious and related work and (iii) application of different methods considering the recent advances in technology. We conclude that hierarchical task analysis was not effective in obtaining a clear, common vision about the work domain. Sto ryboarding was the most useful technique as it allowed discovering novelty fac tors that differentiate the solution and improve the usability of the product, thereby supporting the human work at offshore engineering design and review sessions.

Interactive installations: tales from the trenches

Publication . Campos, Pedro; Campos, Miguel; Jorge, Joaquim A.

Breakthrough innovation can be interpreted as research translated in to products that the market accepts. The process of market translation of several products developed by WowSystems, a Portuguese company specialized in novel interaction paradigms, is explained in this paper as a case study shedding some light into how innovation centers can better promote innovation, in the form of well-succeeded products. We describe two paradigmatic “tales from the trenches” and conclude with some guidelines that were outlined on the basis of more than three years delivering fifty interactive installations.

A multimodal tablet-based interface for designing and reviewing 3D engineering models

Publication . Campos, Pedro; Noronha, Hildegardo

The usage of multimodal user interfaces has revolutionized many different activities. However, most of the interactive technologies deployed in real world engineering contexts are still difficult to use, especially when engineering teams need to collaboratively visualize and review large-scale 3D CAD (Computer-Aided Design) models. This is the case of the oil platform industry, which necessarily involves the review and manipulation of large CAD models. In this paper we present a novel solution, based on multitouch and accelerometer input, which was designed and evaluated in close cooperation with researchers and engineers of a large oil industry company. We evaluated two different conditions: using multitouch-only input and using multitouch coupled with accelerometer-based input. Statistical analysis of quantitative data suggests that the second condition is faster and less error-prone than simply using multitouch-only input. Additionally, qualitative data showed that users perceive the multitouch-only interface as being more accurate, but more difficult to understand and use.

Harnessing virtuality in the real world: a transversal approach

Publication . Noronha, Hildegardo José Quintal; Campos, Pedro Filipe Pereira

This thesis explores a range of Virtual Reality-related technologies in order to solve problems and expand the State-of-the-Art in the fields of Remote Collaboration, Virtual Reality, and Ocean Awareness. It also explores and harnesses the power of supporting technologies, mostly, the Internet-of-Things. The line that separates our lives from Virtuality is becoming more and more blurred. With the rapid expansion of Virtual Reality, new problems arise, both from a technical and theoretical point-of-view. This thesis explores Virtual Reality from a low-level, ”cold metal” side - such as tracking - and a high-level, ”warm feelings” side - such as emo tions. With Virtuality in mind, this thesis tries to improve Remote Collaboration based on a real-world problem of working engineers that need to cooperate in real-time en gineering endeavors while not being present in the same physical space. It explores Gamification and a mix of Augmented and Virtual Reality to improve the experience quality of remote working. Finally, this thesis takes an approach to Ocean Awareness with the help of holography, green building, and the Internet-of-Things in order to build public displays that rely on data that is collected from the marine fauna, transport it, and display it in near-real-time. This thesis also presents and discusses a set of lessons learned during these ex periments and outlines a set of design recommendations for these contexts. It has a direct impact on the industries that depend on remote collaboration as well as indus tries that need novel ways to persuade users such as ocean awareness and human well-being and improves the State-of-the-Art in Virtual Reality
