Today marks the 100th day of my annual #StillStanding project. In this blog post, I summarize some of my experiences so far. Endurance Some people questioned whether I would be able to stand still every single day for an entire year. But, hey, it is only ten minutes (out of 1440) per day, and even though my life as a centre director is busy, it is always possible to find time for a standstill sometime during the day....
Sometimes it is necessary to check, remove or modify the metadata of PDF files. Here is a quick post to show how it can be done in the terminal on Ubuntu Checking PDF metadata Most PDF viewers have an option for showing the metadata of PDF files. This can also be done in the terminal using the “pdfinfo” command-line tool. First, we need to install the “poppler-utils” package: sudo apt install poppler-utils Once installed, you can check the metadata by using the following command:...
For my annual Still Standing project, I am recording 360 videos with audio and sensor data while standing still for 10 minutes. I have started exploring how to visualize the sensor data best. Today, I am looking into visualization strategies for 360-degree images. I have written about how to pre-process 360-degree videos from Garmin VIRB and Ricoh Theta cameras previously. The Theta records in a dual fisheye format like this:...
What is the difference between sound and audio? I often hear people confuse the terms. Here are a couple of ways of thinking about the difference. A good summary can be found in this blog post: Sound is vibrations through materials Audio is the technology to hear sounds coming from natural or human-made sources Another good definition is that audio is electrical energy (active or potential) that represents sound. From this, a sound recording is stored as an audio file....
I am happy to announce a new online course from RITMO: Pupillometry – The Eye as a Window Into the Mind. This is the third so-called Massive Open Online Course (MOOC) I have been part of making, following Motion Capture and Music Moves. I am excited to get it started on Monday, 16 January. Discover the applications of pupillometry research Pupillometry is a relatively new research method within the sciences, and it has wide-ranging applications within psychology, neuroscience, and beyond....
Today, I ran a workshop called Video Visualization together with RITMO research assistant Joachim Poutaraud. The workshop was part of the Digital Scholarship Days 2023 organized by the University of Oslo Library, four days packed of hands-on tutorials of various useful things. Presentation slides made by Jupyter Notebook Joachim has done a fantastic job updating the Wiki with all the new things he has implemented in the toolbox. However, the Wiki is not the best thing to use in a workshop, it has too much information and would create an information overload for the participants....
For my annual Still Standing project, I am recording sensor data from my mobile phone while standing still for 10 minutes at a time. This is a highly curiosity-driven and data-based project, and part of the exploration is to figure out what I can get out of the sensors. I have started sharing graphs of the linear acceleration of my sessions with the tag #StillStanding on Mastodon. However, I wondered if this is the sensor data that best represents the motion....
Yesterday, I completed my 365 Sound Actions project, during which I recorded one sound action per day as part of preparing for the launch of my book Sound Actions. Today, on 1 January 2023, I start this year’s project: recording myself standing still 10 minutes every day. You can follow the progress on Mastodon. Starting up AMBIENT Although I am happy about completing my sound actions project, I have enjoyed the ritual of doing something every day....
1 January this year, I set out to record one sound action per day. The idea was to test out the action–sound theory from my book Sound Actions. One thing is writing about action–sound couplings and mappings, another is to see how the theory works with real-world examples. As I commented on after one month, the project has been both challenging and inspiring. Below I write about some of my experiences but first, here is the complete list:...
I am doing some end of the year cleaning on my hard drive and just uploaded the Jupyter Notebook I used in the analysis of a mobile phone lying still earlier this year. For some future studies, I thought it would be interesting to explore the PDF export functionality from Jupyter. That worked very well except for that I didn’t get any title or author name on top: Then I found a solution on Stack Overflow....
