1906 SF Quake Stereo Photos

Thursday, March 10th, 2011

My friend Tim shared a link to an interesting post about some very early color stereo photographs taken of the 1906 SF quake.

I figured it would be fun to try to combine them into animated gifs – like you do. Here’s how they turned out.

(I think the final one might have been restored or something? It looks like the plates are identical in one part on the lower right)

Pretty print javascript with enscript

For future reference, the following command will format a javascript source file as a 2-up syntax highlighted postscript file (you can open this in

enscript -2Gr --color -Ejavascript file.js

Move to get moved

Thursday, January 20th, 2011

“…if one truly likes to design for movement-based interaction, one has to be or become an expert in movement, not just theoretically, by imagination or on paper, but by doing and experiencing while designing. So, besides having knowledge of the salient aspects of embodied interaction, one has to move in order to design movements.”

Lego Augmented Reality

Nice use of augmented reality on this Lego packaging. I haven’t seen this myself yet. Must keep an eye out the next time we’re down town.

Reverse Surface Mounting of SMD Components

'Reverse' SMD mount

'Reverse' SMD mount

Interesting method for mounting SMD components. The “circuit writer” pens might also be worth checking out.

This tutorial for is those of you who absolutely need to mount a small surface mount device for prototyping purposes and do not have the means or time to pefrom a traditional surface mount.

Thanks to Jo for the tip.

Quite Quiet

A quiet day at the office

A quiet day at the office

It’s the week between Christmas and New Year. Most of the office is away on holiday, so it’s very quiet today. We missed out on a white Christmas (beyond a few fitful flakes), but the weather seems to turned colder over the last couple of days. It would be nice to get some snow sometime in the coming week.

I took a couple of days off last week, but today I’m back at my desk. There’s really only one job for me to concentrate on; my thesis revisions. I’m going to focus my efforts towards presenting something at my research group meeting next Monday. Having small doable short-term goal is probably a good way in to this big scary task.

Convert .pptx files to .ppt on OSX

Microsoft office open xml converter

Microsoft office open xml converter

If you’re still using Office 2004 on OSX and receive .pptx files from colleagues, you won’t we able to open them directly. Instead, download the (snappily titled) Microsoft Office Open XML File Format Converter and you’ll have a drag/drop interface for converting these, and other of the new office file formats.

OpenCycleMap for Sønderborg

Saturday, November 29th, 2008

I was happy to find out about this project called OpencCycleMap today. It maps cycle tracks as well as other features such as places for parking your bike (key here). The maps are based on data from the OpenStreetMap project, which is an free and editable map of the whole world; kind of like wikipedia for maps

I was really surprised at how detailed the map for Sønderborg is and also surprised that it marks the location of public recycling bins. Do cyclists have a special need for this information?

Unfortunately, I couldn’t find an easy way to embed the map in this blog post other than resorting to using an iframe (which would require a word-press plugin such as embed-iframe). It’s a bit of a heavy-handed approach, especially when the embedded page is not optimized for viewing at 450×350 pixels (those boxes of links at the bottom really get in the way and it would probably be better if scroll-zooming were disabled).

Therefore, I switched to a screen-shot of the site. Click the image to go to the live map.

Summary: Co-experience: user experience as interaction

Wednesday, July 9th, 2008

A summary of:

Battarbee, K. & Koskinen, I., 2005. Co-experience: user experience as interaction. CoDesign, 1(1), 5-18 (online article).

In recent years, the idea of user designing for experience has emerged as an important concept and goal for the field of interaction design. Experience has been a useful notion for helping think beyond usability as the primary goal for interaction design. This is necessary, because although usability is itself still important, a focus on usability alone does not give insight into other aspects of interaction, such as pleasure, desirability and so on.

The authors point to the following three approaches to the study and interpretation of user experience in design

  • Measuring approach: builds on the approach that experiences can be measured by emotional reactions. This can be either by directly measuring physiological reactions that are linked to emotional states (skin conductivity, heart-rate) or by assessing people’s emotions subjective reports.
  • Empathic approach: seeks to link experiences to the emotional needs, desires and motivations of individuals. This leads to the need for designers and researchers to develop rich empathic understandings of these aspects of people’s experiences.
  • Pragmatist appproach: borrows from pragmatist philosophy and proposes that experiences grow from interactions between people and their environment. Fleeting, fluent subconscious experiences can form meaningful chunks of experience for people and be demarcated as ‘an experience’. These may in-turn be elaborated through stories into ‘meta-experiences’, collections of individual experiences.

The authors point out that each of these approaches to the study of experience for design has focussed on experience as an individual phenomenon. They propose that interactional aspects of experience should also be considered. They draw on a symbolic interactionism approach, and propose ‘co-experience’ as a framework within which individual experiences emerge and change as they become part of social interaction. This is based on three principles from symbolic interactionism. First, that people act towards things through the meanings that those things have for them. Second, that meanings arise from interaction with others. Third, that meanings are part of an interpretive process of a person encountering things (I’m not entirely sure about my use of the word ‘things’ in this sentence).

The authors then use this model to explain how experiences migrate from the unconcious background of ongoing experience, to concsious and deleniated experiences (an experience), to collaboratively elaborated and shared stories (meta-experiences). This is proposed through the mechanisms of ‘lifting up experiences’ (communicating an to others about an experience), ‘reciprocating experiences’ (acknowledging and responding to an experience that another person has shared) and ‘rejecting and ignoring experiences’ (rejecting or downgrading an experience that another person has shared).

The researchers explore, elaborate, and illustrate these processess of migration with the results of a study into the use of a multimedia messaging service. They show how the back and forth of message between people using this system functioned in terms of establishing meanings around the experiences that were shared. A methodological difficulty of the study (one acknowledged by the authors) is that the study only captured interactions that took place through the medium of the multimedia messaging service, so other channels of communication that might have served to lift up, reciprocate, or reject experiences are not visible.
