thesis visualization

using textexture.com, thanks to a tip from Bryan Alexander. Doesn’t mean a whole lot at first glance, but it sure is purty. This is chapters 4 and 5 of my thesis (textexture choked on the whole thing):

fun with bike data visualization

D'Arcy Norman — Sat, 18 Aug 2012 22:58:36 +0000

I just picked up a license for the fantastic OmniGraphSketcher application. I’m using it to build the visualizations for my thesis, and wanted to see what it would do with my bike tracking data. OK. I was procrastinating, and couldn’t force myself to work on the thesis. But, at least I’m learning how to do more cool stuff with data, right? cough

Anyway. Here’s a visualization of almost 2 and a half years of data stored in Cyclemeter on my iPhone. I exported the activity history in monthly aggregate, and took the .csv file into Excel to select the rows, which were then pasted into OmniGraphSketcher. The visualization shows total distance (divided by 10, so the distance data points fit in the same range as speed data), average speed and maximum speed per month. I also overlaid lines to show which bike was being used. The Kona wound up being my winter bike, and my Cannondale is my fast summer bike. It’s pretty easy to see where the snow and ice crapped up my rides

compare the OmniGraphSketcher graphic above, with one I created directly in Excel back in July:

yummy visualizations

I’m trying to make the data as visible as possible. Turns out, I had to make up a few visualization styles to do it. Think there’s something there…

Pretty pictures. Now, with words!

Visualizing simultaneous presences

WordPress in red, blackboard in blue. Showing the number of CoI presences indicated per day in each platform. WordPress consistently showed more fully-rounded presences (social, teaching and cognitive) while blackboard more commonly was restricted to just 1 or 2 simultaneous presences. Interesting.

discussion visualization with gephi

D'Arcy Norman — Wed, 04 Apr 2012 04:37:55 +0000

I’ve been playing around with gephi today, to see what I could come up with to display the discussion threads from my research data. Lots of manual data entry later, and I’ve got this:

and this:

WordPress sites are shown in red, Blackboard discussion forums in blue. So far, just a pretty picture, but I’ll hopefully be able to coax out a diagram or two that shows the difference in interaction patterns between the two platforms…

The data in a nutshell

D'Arcy Norman — Sun, 01 Apr 2012 00:17:42 +0000

The Community of Inquiry coding data, aggregated and compared. The WP posts showed more indicators of cognitive, teaching and social presence, across the board. Also interesting is that the instructor was only minimally active in WP – the teaching presence indicators were made by students…
