    Visual data analysis facilitates human-data interaction by highlighting patterns, anomalies and alert conditions in reporting views...tables of data ready for human consumption. Visual data analysis enables data to be interpreted holistically by exposing contextually meanful attributes of the data set such as patterns, trends, structure, and exceptions. Visual data analysis may build upon prior logical processing via mathematical formulas, artificial intelligence or other automated mechanisms for analysis and improving data quality. Strictly speaking, visual data analysis primarily focuses on visual presentation of tabular views ready for human consumption.

2010 Horizon Report » Four to Five Years: Visual Data Analysis - 0 views

  • Visual data analysis blends highly advanced computational methods with sophisticated graphics engines to tap the extraordinary ability of humans to see patterns and structure in even the most complex visual presentations.
  • Data collection and compilation is no longer the tedious, manual process it once was, and tools to analyze, interpret, and display data are increasingly sophisticated, and their use routine in many disciplines.
  • In advanced research settings, scientists and others studying massively complex systems generate mountains of data, and have developed a wide variety of new tools and techniques to allow those data to be interpreted holistically, and to expose meaningful patterns and structure, trends and exceptions, and more.
  • ...8 more annotations...
  • Researchers that work with data sets from experiments or simulations, such as computational fluid dynamics, astrophysics, climate study, or medicine draw on techniques from the study of visualization, data mining, and statistics to create useful ways to investigate and understand what they have found.
  • The blending of these disciplines has given rise to the new field of visual data analysis, which is not only characterized by its focus on making use of the pattern matching skills that seem to be hard-wired into the human brain, but also in the way in which it facilitates the work of teams working in concert to tease out meaning from complex sets of information.
  • it possible for almost anyone with an analytical bent to easily interpret all sorts of data
  • Many are free or very inexpensive, bringing the ability to engage in rich visual interpretation to virtually anyone.
  • Online services such as Many Eyes, Wordle, Flowing Data, and Gapminder accept uploaded data and allow the user to configure the output to varying degrees.
  • By manipulating variables, or simply seeing them change over time (as Gapminder has done so famously) if patterns exist (or if they don’t), that fact is easily discoverable.
  • The promise for teaching and learning is further afield, but because of the intuitive ways in which it can expose complex relationships to even the uninitiated, there is tremendous opportunity to integrate visual data analysis into undergraduate research, even in survey courses.
  • Visual data analysis may help expand our understanding of learning itself. Learning is one of the most complex of social processes, with a myriad of variables interacting in highly complex ways, making it an ideal focus for the search for patterns.

Visual Data Analysis, Scientific Computing - 0 views

  • Visual Data Analysis (VDA) tool packages are powerful software tools that allow the development of complex solutions to visualize and analyze data.
  • The imaging features of a VDA package are often the most tangible aspect of the tool, but the overall effectiveness of a package is really based on its data manipulation and analysis capabilities.
  • A robust and flexible VDA tool should contain a broad range of mathematical, statistical and data manipulation capabilities, which are seamlessly tied to the visualization components through a high-level array-based scripting language.
  • ...5 more annotations...
  • Support for popular formats (XML, CDF, HDF, binary, ASCII, TIF) should be included in the base product, and services for customized data handlers should be available through the provider.
  • There are several factors that determine or impact performance, including use of pre-built data manipulation functions, limitations on data set size, parallelization, supported data types, and performance of the package's algorithms.
  • In general, the best performers will be the packages that support a broad range of data types, thus minimizing impact on memory requirements; support parallelization technology such as OpenMP; and have kernels optimized for visual data analysis.
  • Various techniques, solutions, and products are available on the market to visually analyze data, but few offer a full spectrum of visualization capabilities coupled with sufficient complementary analytical functionality.
  • In conclusion, a careful evaluation of key VDA tool characteristics, with the end solution in mind, should factor into the selection process to include the combined functionality, reliability, scalability, performance and portability of a VDA tool.

Visual Business Intelligence - Microsoft Excel's Idea of Visual Data Analysis - 0 views

  • No software product is used more than Microsoft Excel for the analysis and presentation of quantitative data.
  • Nevertheless, it is fair to say that you can use Excel to present data effectively, but within severe limits, and only if you’re willing to work around its problems.
  • To say it can be used for visual data analysis, however, is a stretch that exceeds its reach. To date, Excel is at best an infant in the world of visual data analysis, barely able to roll over.

How Privacy Vanishes Online, a Bit at a Time - NYTimes.com - 0 views

  •  
    Data that is innocuous or is it? Excellent article from the New York Times on Privacy. "In a class project at the Massachusetts Institute of Technology that received some attention last year, Carter Jernigan and Behram Mistree analyzed more than 4,000 Facebook profiles of students, including links to friends who said they were gay. The pair was able to predict, with 78 percent accuracy, whether a profile belonged to a gay male. So far, this type of powerful data mining, which relies on sophisticated statistical correlations, is mostly in the realm of university researchers, not identity thieves and marketers. But the F.T.C. is worried that rules to protect privacy have not kept up with technology. The agency is convening on Wednesday the third of three workshops on the issue. "

Augmented Reality choosing Utility over Gimmick | Hello Mobile! The Interactive Mediums... - 0 views

  • Shortly after reading that Augmented Reality was the hot-topic at this years International CTIA Wireless conference , I caught an NY Times piece on AR’s tie in to portable real estate listings. Upon reading, I was quickly convinced that mobile augmented reality can reshape tourism, real estate and travel and is already beginning to.  From there I began pondering how it could be applied successfully to other industries such as retail. Clearly the opportunity is there. Industry reports say that mobile handset integration will make a significant impact on Augmented Reality and catapult the industry size to over $350MM. Secondly, It is a technology that when done well can add incredible levels of utility to a mobile device.  So far the mobile AR concept is simple, add live data population (metadata) to what you are already looking at through your mobile devices camera, or respond to an image capture with data. Whether it is a real estate listing, a state monument, or an important location in relevance to the Beatles’ history.  Once you point your camera, the information pops up right over it on your screen. Given the opportunity & usefulness it seems like a wise choice for companies to adopt early. However, companies looking for ROI must enter this arena with the intention to offer utility & improve the lives of their customers, not just give them a fun gimmicky display of a new technology (see Fanta, or Coke Zero).  While some say this technology is going to be quickly “overhyped and abused” many will find new and innovative ways to increase convenience in consumer’s lives, in turn for brand allegiance. Big box store IKEA is already testing out a future augmented reality catalogue showcasing building instructions. It’d be even better if you could use the pictures of your own home from your mobile device to find out while in store what that red chesterfield would look like in your living room. As for grocery innovation, imagine walking into the canned beans section of your local supermarket on a hunt for the lowest sodium beans. With an application dedicated to healthy eating, you could potentially point your camera at the entire beans category and it could point you directly to the can with the lowest amount of sodium. Recipes would be a simple way to innovate & add useful data. Perhaps Mixology could help you think of drink recipes before hosting a party while you are shopping at the liquor store, all you would have to do is point your camera at a bottle of vanilla infused vodka and presto! Whatever the use, AR is quickly becoming a respected medium and one of the most advanced marketing utility tools. As for other industries that can quickly be transformed the ones that come to mind are transportation, greeting cards, restaurants, and cinema. Those who adopt and integrate into their mobile strategies early will win customers & gain big shares of the opportunity, while those who sleep on this will likely get outshined by their competitors.

The Next Wave of AR: Exploring Social Augmented Experiences at Where 2.0 | Ug... - 0 views

  • 1) “Augmenting the map as interface: AR and Locative Narratives” - Jeremy Hight *Map augmentation of the historic route 66 can house an essay contest and publication globally but as embedded within that map augmentation instead of books or even web sites. * A place on a map can be a graphic index and database to save and collect the writing of that place with a graphic or textual search index. *One can pop immersive visualizations of abandoned or lost buildings from map location in shared software and collectively augment (imagine channels within the lost core of detroit where one is memories and accounts tagged within parts in the immersive visualization while another is of poems and stories written by people moved by the place and its semiotics and story). *The news stand is to be the map. *New forms of literature will be born of mapping, spaces,augmentation and new tools
  • “With the exotic mixed realities envisioned by futurists and science fiction writers seemingly around the corner, it is time to move beyond questions of technical feasibility to consider the value and impact of turning reality inside out for everyday social settings and experiences. Thanks to the inherently social nature of augmented reality, we can be sure the value and impact of many augmented experiences depends in large part on how effectively they integrate with the social dimensions of real-world settings, in real time.”
  • I will have the awesome privilege, on our Where 2.0 panel, of showcasing ARWave.   We will  premier the ARWave demo which shows how ARWave has accomplished the basics of geolocating data on Wave Federation Protocol (and real time collaboration on this geolocated data).  If you’re interested in the ARWave project join the Mailing list, FAQ are here, and have a peek at the current state of development at Google Code, and the specification for an AR Blip.  We also have Waves for the project hosted on Google Wave.  You can join the general discussion here, and the technical side here.

  • “The possibility exists to take a part of an area and overlay a dystopia, a utopia, multiples of each of these, or even recreations of previous incarnations in the past. Writing and publication thus cannot only be of place, and form(s), but of selected augmentations of icons, streets, buildings and related texts on top of the map. These spaces can be built in real time and can be turned on and off as channels of augmentation that over time illustrate many faces of place in its present, past, possible futures,etc. with texts within these alternate spaces as commentary, as fused aesthetic analysis, or simply creative writing relevant to these charged and hybrid spaces.”
  • “Layar has a killer browser already,  ARWave would add social features. They can keep their “walled garden” of data and still join the federation of open data too ” (Thomas Wrobel) Yup, that is the cool part of federation – you can have your cake and eat it too! Sophia Parafina and I will be organizing a discussion session on ARWave and Federation at WhereCamp, right after Where 2.0, April 3rd and 4th, and Dan Peterson who is in leading the federation effort for Google Wave will join us. The diagrams below illustrate how ARWave and federation can revolutionize the way we share our augmented realities.
