sleepGalaxy: final design

There were still a couple of variables to visualise once the basics design was ready. I had to work on integrating my pre-sleep activity. In the end I used three activity types: sport, social and screen (computer and television). Of the first two I’d logged duration by recording start and finish time. For screen time […]

sleepGalaxy: design & calories

I’ve been working on the overall design step by step, alternating between coding and looking. I want to incorporate my calorie intake after 6 PM. I’m not recording the times I ate and I suspect they influence my whole sleep. So the most logical position is to circle all around the “sleep circles”. There is […]

breathing_time at the Quantified Self conference

On May 12th I lead a breakout session at the second European quantified self conference in Amsterdam. The goal was to exchange experiences in breath and group tracking and to demo the new, wireless version of the breathing_time concept. I started the breakout with an overview of the previous version. We soon got into a […]

working with data

I’ve been experimenting with the design and data visualisation using the personal data values: mood, stress, energy level and inner peace. Depending on the data value the lines, shapes and tone of each visualisation varies. This will create a different structure for every timeslot in every day. Inner peace will be a big organic and […]

device and software

I’m currently developing the device design and the software for breathing_time. I realise now that the form factor of the device must come from the possibilities of the wind sensor. It works best when the breath is guided to the sensor. That way I can detect inhaling and exhaling. I’ve been trying out different sizes […]

discovering breath

I’ve upgraded my code for the stretch sensor graph in Processing. The sensor outputs numbers. When I breath in or out the number gets lower. Detecting breathing activity isn’t as easy as looking for a numbers below 200 for example. Because over the time of wearing the sensor the whole range of numbers starts to […]
