OCAD University , formerly the Ontario College of Art and Design, is a public university whose campus is located in Toronto, Ontario, Canada. The school is within the Grange Park neighbourhood, and adjacent to the Art Gallery of Ontario. The school is Canada's largest and oldest educational institution for art and design. OCAD U offers courses through the Faculties of Art, Design, Liberal Arts and science, and alternative programs. The enabling legislation is Ontario College of Art and Design University Act, 2002.

From financial statistics to nutritional values, we are frequently exposed to quantitative information expressed in measures of either extreme magnitudes or unfamiliar units, or both. A common practice used to comprehend such complex measures is to relate, re-express, and compare them through visual depictions using magnitudes and units that are easier to grasp. Through this practice, we create a new graphic composition that we refer to as a concrete scale. To the best of our knowledge, there are no design guidelines that exist for concrete scales despite their common use in communication, educational, and decision-making settings. We attempt to fill this void by introducing a novel framework that would serve as a practical guide for their analysis and design. Informed by a thorough analysis of graphic compositions involving complex measures and an extensive literature review of scale cognition mechanisms, our framework outlines the design space of various measure relations-specifically relations involving the re-expression of complex measures to more familiar concepts-and their visual representations as graphic compositions. © 2013 IEEE.

Many datasets, such as scientific literature collections, contain multiple heterogeneous facets which derive implicit relations, as well as explicit relational references between data items. The exploration of this data is challenging not only because of large data scales but also the complexity of resource structures and semantics. In this paper, we present PivotSlice, an interactive visualization technique which provides efficient faceted browsing as well as flexible capabilities to discover data relationships. With the metaphor of direct manipulation, PivotSlice allows the user to visually and logically construct a series of dynamic queries over the data, based on a multi-focus and multi-scale tabular view that subdivides the entire dataset into several meaningful parts with customized semantics. PivotSlice further facilitates the visual exploration and sensemaking process through features including live search and integration of online data, graphical interaction histories and smoothly animated visual state transitions. We evaluated PivotSlice through a qualitative lab study with university researchers and report the findings from our observations and interviews. We also demonstrate the effectiveness of PivotSlice using a scenario of exploring a repository of information visualization literature. © 1995-2012 IEEE.

Interiors: Design, Architecture, Culture | Year: 2012

This article considers a number of recent art and architectural projects that seek to promote "natural" effects in interior spaces at the level of physiological response. Rather than introducing natural objects or materials into the interior, or visually representing nature, these works mobilize environmental controls (temperature, lighting, humidity, etc.) toward the production of affective atmospheres. Exploring the relationship between nature and artifice in this work, this article also draws a parallel between contemporary effects-based architecture and the sensationalist architecture of late eighteenth-century France, and proposes that these recent and historical attempts to stage "nature" as effect in the designed interior might open up new avenues for thinking through the place of nature in culture today. © Berg 2012.

In this commentary the author poses the question: can the "curb-cut" phenomenon (a phenomenon holding that innovations motivated by a desire to address the challenges faced by persons with disabilities benefit the broader majority) be scaled to help address our society's greatest global challenges? The article describes an international initiative that leverages the World Wide Web to address the economic exclusion of people with disabilities and maps out how this may help to address the broader issues of our current markets, education, employment, and financial systems. © 2014 John Wiley & Sons, Ltd.

Visual representations of time-series are useful for tasks such as identifying trends, patterns and anomalies in the data. Many techniques have been devised to make these visual representations more scalable, enabling the simultaneous display of multiple variables, as well as the multi-scale display of time-series of very high resolution or that span long time periods. There has been comparatively little research on how to support the more elaborate tasks associated with the exploratory visual analysis of timeseries, e.g., visualizing derived values, identifying correlations, or discovering anomalies beyond obvious outliers. Such tasks typically require deriving new time-series from the original data, trying different functions and parameters in an iterative manner. We introduce a novel visualization technique called ChronoLenses, aimed at supporting users in such exploratory tasks. ChronoLenses perform on-the-fly transformation of the data points in their focus area, tightly integrating visual analysis with user actions, and enabling the progressive construction of advanced visual analysis pipelines. © 2011 IEEE.
