Last week was very exciting. I put my system to the test during group experiments. I did 10 sessions in total at three different locations and gathered data from 23 different participants. People could register for beginner or advanced sessions with consisted of 20 or 60 minutes of meditation respectively.
New for me was working with Eventbrite. Through this system participants could register and select the appropriate suit size (only 5 suits were available in 3 sizes). I am very pleased at how this went. People could interact with me through the platform and it was easy to change orders. Some participants couldn’t make it but all graciously let me know in time.
Setting up experiments
Simon from Protospace had worked very hard to get the system ready for conducting the group experiments. I can now register users. The system creates a unique random ID allowing users to take part anonymously. Suits can be added and named.
Every time I want to experiment I create meditation session (duration, actuation). To this session I add users, assign suits to users.
Create experiment (name, comment), add sessions to experiment and see completed and incomplete experiments.
The starting and stopping of a session goes through the server with a nice bell sounding at the beginning and end. This also automatically starts and stops the logging of data.
Each user can fill in their own form through a dedicated URL which is available as long as a session is active. Eventually we want all users to be able to use their own device to fill out the forms but at the moment the style sheet isn’t compatible with every device.
I was very happy to see that users love the look of the suits, many selfies were taken. It wasn’t a surprise that people found the suit comfortable to wear. Vera de Pont and I spend many hours optimising the fit of and interaction with the suit. The hood was used quite often for a feeling of privacy and safety. The hood also provides warmth which is nice when sitting still. People felt that the hood made it easier to turn inwards.
Some people did have a problem with the collar. It is made of soft, flexible fabric and designed to fit snugly around the neck. The close fit will ensure that even the tiniest movements are captured. But even when the collar is fastened less tightly the data is comparable to the tight fit.
The sessions could be conducted as normal meditation sessions. As an observer it struck me how peaceful they were. There wasn’t more movement or restlessness then in any other meditation session. The technology did not seem to interfere with the meditation.
Filling in the questionnaires was a bit of a hassle due to issues explained above. I have worked mostly with 2 laptops which could be used by the participants during walking meditation. But the filling out does take a lot of time, especially when the questions are new to people. Also some of the questions sometimes puzzled participants. Some questions are based on Buddhist theory, not all users are familiar with that.
The experiment design was that each 20 minute session would test one type of light. Although I explained this clearly on the ticket registration page people had different expectations. Some people expected a more dynamic light. These are interesting things to explore in the future but at this point the most important thing is to find a relation between the light and the meditation quality. The more I vary, the harder this will be, especially as my dataset still isn’t that big.
The blue light in particular was experienced very differently by people, while some found it relaxing others got a headache… One participant suggested to use indirect light. A very good idea. That way you are not watching a light source but are just experiencing the radiance. I have been testing it and have found it much more comfortable.
Participants are much interested in the biometric data. At this point there is only limited possibility to view the data. It would take too much time to show every user. All participants will get plots and a summary of their data of the sessions they participated in. The people that did look at their data found it mostly confirmed their feeling about the experience. They could for example recognize their fidgeting during a session and the deepening of the breathing between sessions.
We are working towards an overview of all sensor data on one page, providing mean values and comparison of sessions. Making the experience of the data more meaningful and helpful is something I will be exploring in the near future. It is a study in and of itself.
The experiments were about testing the suits and the system. Working with so many people has been really worthwhile. I have much better insight into what works and things in the system and experimentation routine that can be improved. The data of different users will be fed to the smart algorithm to help improve it so it can create the most optimal light during meditation.
