SketchSim: Interactive Simulation of Ink Brushstrokes

Published in Workshop of Undergraduate Work (WUW) at SIBGRAPI'08, 2008

The simulation of ink and brushes, one of these instruments, is the object of study of this paper. Several techniques are discussed and implemented in an interactive artistic tool, called SketchSim. Artists have used this tool as part of a brief qualitative analysis, which is also discussed in this paper.

Touching the depths: introducing tabletop interaction to reservoir engineering

Published in ACM International Conference on Interactive Tabletops and Surfaces (ITS'10), 2010

Modern reservoir engineering is dependent on 3D visualization tools. However, tools used in this domain are not fully aligned with the reservoir engineer's interactive needs, and do not address fundamental user issues, such as collaboration. We base our work on a set of observations of reservoir engineers, and their unique interactive tasks and needs. We present insightful knowledge of the domain, and follow with a prototype for an interactive reservoir visualization system, on the Microsoft Surface.

Designing snakey: a tangible user interface supporting well path planning

Published in IFIP Conference on Human-Computer Interaction (INTERACT'11), 2011

We present our ongoing design of Snakey, a tangible user interface (TUI) dedicated to the field of reservoir geosciences and engineering. Our design of Snakey emphasizes intuitive manipulation and interaction with 3D curves, common to underground well path exploration and planning. Snakey is not designed to replace the traditional CAD reservoir well path planning tools, but rather to augment them with tangible and collaborative interaction, facilitating spatial exploration during the multi-stage planning processes involved in well path design.

Seamless mixed reality tracking in tabletop reservoir engineering interaction

Published in Proceedings of the International Working Conference on Advanced Visual Interfaces (AVI'12), 2012

In this paper we present a novel mixed reality tracking system for collaborative tabletop applications that uses decorative markers and embedded application markers to create a continuous and seamless tracking space for mobile devices. Users can view and interact with mixed reality datasets on their mobile device, such as a tablet or smartphone, from distances both far and very near to the tabletop.

Watchboard: curated microblogging for the enterprise

Published in CHI'14 Extended Abstracts on Human Factors in Computing Systems, 2014

Traditional microblogging in the enterprise is known to increase work environment awareness, but is also coupled with information overload and privacy issues. We address these challenges by introducing the concept of curated microblogging, which proposes the addition of social curation and access control to such platforms. We also present Watchboard, a prototype tool incorporating these ideas, and discuss highlights of a preliminary user study delineating crucial factors of the proposed concept.

Deciding when and how to move HPC jobs to the cloud

Published in IEEE Computer, 2015

Now used for high-performance computing applications, the cloud presents a challenge for users who must decide, based on efficiency and cost-effectiveness, when and how to run jobs on cloud-based resources versus when to use on-premise clusters. The authors propose a decision-support system to help make these determinations.

Medstory: unlocking the qualitative power of medical narratives

Published in Workshop on Visual Analytics in Healthcare (VAHC'17), 2017

Medical narratives are a qualitatively-rich component of medical records with limited visualization support. In this work we propose a text-centered approach for medical narrative visualization to better support their complexity, based on design goals derived from the literature and a formative study.

Doccurate: A Curation-Based Approach for Clinical Text Visualization

Published in IEEE transactions on Visualization and Computer Graphics (TVCG) (VAST’18), 2018

In this work we present Doccurate, a novel system embodying a curation-based approach for the visualization of large clinical text datasets. Our approach offers automation auditing and customizability to physicians while also preserving and extensively linking to the original text. We discuss findings of a formal qualitative evaluation conducted with 6 domain experts, shedding light onto physicians’ information needs, perceived strengths and limitations of automated tools, and the importance of customization while balancing efficiency. We also present use case scenarios to showcase Doccurate’s envisioned usage in practice.

DataQuilt: Extracting Visual Elements from Images to Craft Pictorial Visualizations

Published in Proceedings of the 2020 CHI Conference on Human Factors in Computing Systems (CHI'20), 2020

We present DataQuilt, a novel system that enables visualization authors to iteratively design pictorial visualizations as collages. Real images (e.g., paintings, photographs, sketches) act as both inspiration and as a resource of visual elements that can be mapped to data.

A Teaching Language for Building Object Detection Models

Published in Proceedings of the 2020 ACM Designing Interactive Systems Conference (DIS'20), 2020

Object detection models rely on deep networks that offer model builders limited agency over model construction, refinement and maintenance. We propose and assess an expressive teaching language for specifying object detectors which includes constructs such as concepts and relationships. We identified language building blocks and articulated design goals for creating interactive experiences in teaching object detection.
