- Bird-watching Turns To Technology (BBC) — CCTV-esque automated bird watching. Sensor networks + computer vision for an ecological purpose. In a bid to track the guillemots behaviour, Dr Dickinson is refining established work that involves modelling the visual structure of an area around a nest. The computer system will be able to use this model to identify changing elements in the scene, and determine if they correspond to movement by a guillemot. “That is the typical way of doing surveillance,” said Dr Dickinson, “work out what’s moving, that gives you an idea about what is interesting in a scene.”
- The Case for Open MTA Data — If you live in Portland, there are dozens of mobile applications that help fill gaps in transit information. You can check your phone to see when the next bus is supposed to come. You can plan a trip from one unfamiliar part of town to another. You can even have your mobile device buzz if you fall asleep before reaching your destination. For the basic stuff, there’s no iPhone necessary (although that certainly helps for information luxuries). Anyone who has a plain old cell phone with text messaging can ride the train or the bus with greater ease thanks to these apps. (via Making Light)
- PyMT — a python module for developing multi-touch enabled media rich applications. Currently the aim is to allow for quick and easy interaction design and rapid prototype development. There is also a focus on logging tasks or sessions of user interaction to quantitative data and the analysis/visualization of such data.
- Near Realtime Face Detection on the iPhone with OpenCV Port — we’re probably only one or two revisions of iPhone hardware away from being able to do some serious computer vision tasks on the handset. Proof of concept adds a tie to the face you’re pointing the camera at.

Augmented Reality, A/B Psych, Open Source Heartbeat, Launchpad Launches
- ARtisan — AR Flash library, the fastest and easiest way from point A to point B in browser based augmented reality. Love the demos on the home page. (via and bjepson)
- How to Increase Sign-ups By 200% — A/B testing from 37Signals showed that “See Plans and Pricing” got twice the clickthroughs of “Free Trial!” and variations thereon. (via kathysierra on Twitter)
- Open Source Heart Monitor, Possible Blood Sugar Level Detector — another step forward in sensor networks and personal data: I’ve set up a quick prototype of a device that will monitor my heart rate while I sleep. It includes a BUGbase + BUGvonHippel module (from my company Bug Labs). I’m also using a custom module we put together that uses a Polar radio receiver (from Sparkfun) and a Polar strap that I wear around my chest. Lastly, we wrote a simple program that runs on the BUG to log the data. (via chr1a on Twitter)
- Launchpad Opensourced — Canonical’s code hosting and collaboration platform that was heavily lusted after in the open souce world, finally open sourced and in its entirety. GNU Affero license.
Web Awards, Speed Thrills, Magazines in the Cloud, Augmented Reality
- The Onyas — New Zealand web design awards launch, from the people behind Webstock and Full Code Press. The name comes from “good on ya”, the highest praise that traditionally taciturn New Zealanders are allowed by law to give.
- The Year of Business Metrics: Don’t make your users run away! — wrapup of the Velocity conference. AOL: Users who had a slower experience view far fewer pages. Some interesting notes on performance from a Google-Bing study: Notice that as the delays get longer the Time To Click increases at a more extreme rate (1000ms increases by 1900ms). The theory is that the user gets distracted and unengaged in the page. In other words, they’ve lost the user’s full attention and have to get it back. [...] As much as five weeks later, some users, especially those who saw delays greater than 400MS, were still searching less than before. (via timoreilly on Twitter)
- Printcasting — very simple content management system for print magazines that lets anyone start a magazine, add content, sign up contributors, sell ads, and go. Clever!
- Pachube Augmented Reality Hack — sexy hack that pushes all my buttons: computer vision, Arduino, sensor network, ubiquitous computing, pervasive alternate reality cyborg villians with chalk designs hellbent on world domination and the enslavement of the human race to use as meatsack AA batteries for their sex toys. Okay, four out of five ain’t bad. (via bruces on Twitter)
Art, astronomy and more fun for you in today’s four short links:
- Found in Space — there’s an astronomy bot on Flickr that identifies stars in the night sky, and from the unique positions of the stars figures out what bit of the night sky is looked at and then adds notes for interesting parts of the sky visible in the shot. A brilliant use of computer vision techniques to add value to existing data. (via Stinky).
- 99 Secrets Twittered — Matt Webb is posting a secret a day from Carl Steadman’s 99 Secrets, an early piece of art on the web. Matt’s explanation is worth reading. Ze Frank really made me realize that every web app is a medium for art, for provoking human responses, and now I keenly watch for signs of art breaking out.
- Internet Ephemera — a brief muse on “if we start with the assumption that everything we put online is ephemeral, how does that change what we put online?”
- Pockets of Potential (PDF) — a 52-page PDF talking about opportunities for supporting learning with the mobile devices already in kids’ lives (via Derek Wenmoth).
