This morning, whilst making breakfast, a news article on the BBC Breakfast show caught my eye. I wasn’t terribly interested in the article being presented from the London Stock Exchange but the visualisation of the stocks behind the presenter caught my eye.
Twenty stocks were being updated in real time and being shown using concentric, stacked circles with a dot moving around it. Each time the price changed, the dot flashed. Some circles were red, others green and I assume this is based on whether the price went up or down.
I’ve not found a video of it online yet but searching through YouTube, I came across Daito Manabe’s channel which has these videos of Tokyo Stock Market visualisations.

From my perspective, I was wondering how this might be changed to help the viewer engage with the data through sound. In Finding Trading Patterns in Stock Market Data, Keith V. Nesbitt and Stephen Barrass  explore the use of sound with a visualisation in stock market data. This is more in the alarm sense of sonification and demonstrates its effectiveness in altering a user, such as a trader, to changing patterns.
I wondered whether the strategy could be applied to so that there was a sonification that interested the viewers and gives them a chance to understand the general pattern of the data. Diato Manabe’s algorithms and visualisation are wonderful but the sonar ping is frustrating and doesn’t produce a sense of what the underlying data is doing even though this is provided in the visual data.

The Netherlands Institute for Sound and Vision have a labs site and Twitter feed. I believe that this follows other initiatives such as the Europeana Labs. Fashion houses create some wonderful things in the wearables section, such as the dress that responds to Twitter. “A collaborative development of an artistic responsive fashion collection” explores responsive […]
As part of my latest course assignment, I have been using Cas Cremer’s Scyther tool for one of the questions. It is a Python programme that allows a user to test a protocol for security properties. It is very user friendly once it gets going but I got frustrated with having to go the directory […]
I’ve just started with sonification and auditory displays. Here are some links and articles (some are behind paywalls) that I found of interest. I heard about a sonification of economic data, The Sound of the Economy, on the Foreign Affairs site and an adjoining paper by George Kopeczky describing it, Perspectives in Sonification of Financial Data […]
The aim of this hack is to explore turning the structures of the First Folio texts marked up using Text Encoding Initiative XML (TEI) into notes using the Chuck , PHP and Processing languages. I wanted to explore the processes for transforming the texts for the user and explore different ways of presenting the textual […]
A hat tip to Kirsty Rolfe for favouriting this retweet from Sjoerd Levelt: ICYMI: the lawyers kindly updated their blog after they were informed of the nature of @CathalUK‘s @MedievalReacts. pic.twitter.com/8G37iiGJr2 — Sjoerd Levelt (@SLevelt) April 10, 2015 I highly recommend going to the tweet and viewing the conversation that led to this change. The […]
In the paper “Testing software components using boundary value analysis“, Muthu Ramachandran demonstrates his experience of automating tests to study boundary value analysis on interfaces. He describes the fundamentals of black box testing approaches but at a somewhat higher level than I was hoping for. He demonstrates that the input and output values should be […]
Just listening to Derek Groen of UCL and and former Software Sustainability Institute fellow talk about paper hackathons. Taking the idea of the typical hack where a piece of code is produced, the paper hack also wrote draft science papers in a short time. The projects for the day were pre-selected but it sounds like […]
I have largely moved away from web development but still occasionally get a project or job that has a web element. I would like to think that my current position in terms of projects and studies means that I have developed a different outlook on things that I do. I was having a quick scoot […]
Earlier this month, the British Library was able to bring the surviving manuscripts of the Magna Carta together. A ballot was held to allow 1215 people to view them but the Library have now posted pictures of the event online. There is a chance to see a couple of the manuscripts at the forthcoming Magna […]
