Another DataVis Resource: This time by Google

Monday, March 22nd, 2010

Google now offers a Public Data Explorer. This is another progressing Google Labs Project that looks quite usable yet. The datasets include, among others, minimum wage in europe, world development indicators etc.

Such public data visualizations are good examples of what can be achieved by information visualization. Such as, this small and easy created visual comparision of Agricultural land between the World and Austria lets users quickly examine that Austria’s agriculture is decreasing while the world’s one is still rising.

But have a look for yourself and create your own visualizations. :)

Collection of iPhone and iPad Templates

Sunday, February 7th, 2010

Smashing Magazine recently presented 50 free UI-and-web-design wireframing kits.

Here I present an excerpt, namely parts of the collection of iPhone & iPad templates and resource links that are really useful to create nice (low-fid) prototypes, advertisement pictures, fake-screenshots or whatever you would like: ipad_GUI_PSD by Teehan (www.teehanlax.com) 2010

Thoughts about data visualization

Tuesday, January 26th, 2010

UX User Experience & Interaction Design are two of the most important issues when facing the current use of our World Wide Web. Though, most scientists and developers forget, that the Semantic Web and therefore also the Internet-Data’s Understanding is strongly connected with UE.

Within my future thoughts and projects I will be approaching the Semantic Web from more of a Interaction-Design or respectively user-focussed perspective. So obviously there are many interesting viewpoints to be taken into account when dealin with this wide-ranging issue.

The first question I stated was what are the different ways to look at this topic; here is a short answer to it:

  • Statistical perspective (what is the data?/how does the data look like?)
  • Computer Science perspective (hot to implement data visualization and interaction possibilities?)
  • HCI perspective (how do users interact with data?)
  • Graphic Design perspective (how can data be appealing?)
  • another perspective?

Notes:

To begin with, I would like to use this post to note down a very incomplete listof professionals, conferences, symposia and institutes (which I may update from time to time), that are besides the obwvious ones, dealing with this topic somehow:

Catchphrases, Quotes & other thoughts:

concept of … highly adaptable … up-scaling views …

“Students shall choose projects with high societal payoffs, researchers have to employ the updated science 2.0 strategies, developers have to focus on genuine user needs”

Eventually, one of our best hopes for the future is that a large and connected group of people can change the world!”

Concept: Let us think of what should be achieved by 2020 and do something about it!

Skitour Boesenstein (Rottenmanner Tauern)

Sunday, January 17th, 2010

This weekend we have been to the Small Bösenstein (2395m) within the Niedere Tauern. Though there is not much snow these days in Styria, is was a nice skitouring day. Let me share some impressions with you:

Which Visualizationcomponent for which dataset?

Friday, May 1st, 2009

worlde_jq_blogWhile I am working on many projects dealing with information visualization, I would like to share a good online ressource about this research topic: IBM’s online visualization research site “MANYEYES“.

Finding the right way to view your data is as much an art as a science. The visualizations provided on Many Eyes range from the ordinary to the experimental. We’re deliberately providing a wide array of possibilities since this is an experimental site—and expect to see more soon!

Their featured visualization types include: Network Diagrams, Word Clouds (also links to Wordle), Word Trees, Treemaps, but also the more standard ones as Bubble Charts, Piecharts and histograms, World Maps etc.

Reading through the information given to a specific visualization type (and component) you also find information about for which dataset is it best chosen. => Datasets, such as: unstructured text, proportions, hierarchical structures, continuous change, relationships etc.

Have fun trying some of them out!

HomoZappiens & Digital Immigrants

Saturday, November 8th, 2008

Dear readers,

thank you for reading my blog and I hope you did not wonder why I did not write for a longer time! Due to some work schedules and a sports-accident, I did not finish any blogpost about sports- and webscience-research-news. However, today I write again and would like to introduce two kind of funny terms I thought about while I was describing the difference between Wikipedia and Google to my father:

Most of us are “digital aborigins” and not “digital immigrants” as my parents for instance are. Therefore some terms are quite obvious clearer for us than maybe some relatives and/or aquaintances or even friends. There we may sometimes take sth. for granted but forget, that this knowledge is not as explicit as we thought it to be.

Therefore I would just like to remind you again of thinking sometimes in another perspective and thinking how others would perceive a situation. Some things will straighten out. ;)

CMS-Recommendation: Drupal

Tuesday, April 22nd, 2008

Drupal Logo from official site Today I read about Google Summer of Code (GSoC) for this year (2008). In a nutshell, this is a program which brings students and mentors within the area of Open Source Development together, worldwide.

As for the last years, Google is investing millions of dollars to finance open source development projects of all diiferent kinds; – and this year, 21 Drupal project fellowships have been selected to be granted. So what is Drupal?

Drupal” is not only a publishing content management system but also a steadily evolving base for web-platforms with a big community as driving power. The core is advancing rapidly, so OpenId and new import/export possibilities, many semantic and social network features are becoming part of both the core api as well as system-modules, which can be easily plugged in / integrated later on…

Here you can look up the list of financed Drupal projects within the Google Summer of Code 2008.

Widgetizing your Website

Sunday, September 30th, 2007

Symbolic picture of Usability A new version of Wordpress (Version 2.3) is out now. There are several changes such as security fixes etc. – but the most appealing one is the possibility of widgetizing your sidebar.

After updating/installing (which was as easy as always) the new version you have a new option within the “Presentation”-Tab that is called “Widgets”. Within you have the possibility to add widgets to your sidebar. Notice, that some pesonalized themes have to be extended by adding the functions.php to your theme-folder and additionally add the following code to your sidebar.php within your theme-folder:

<?php
/* Widgetized sidebar, if you have the plugin installed. */
if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar() ) :
?>
<?php /* some addition stuff ...*/ ?>
<?php endif; ?>

Apart from the fact that the tagloud widget has become a standard feature within Wordpress (v.23), you can also add more widget plugins by uploading new plugins/widgets to your plugins-folder and activating them. Then simply drag and drop those you would like to show within your sidebar.

I recommend seeing the official list of WordPress Widgets.

Some few widgets that are worth mentioning are:
