The project purpose is to analyse a subject physiological signal in a stressing environment, thus the experiment takes place on a two-way transit street (not controlled by traffic lights).
The experimental protocol its repeated for 4 trials and is described in the following:
- 1 minute baseline recording;
- the volunteer walks safely back and forth om the side walk for 30 + 30 meters;
- a resting time is given to the volunteer;
- 1 minute baseline recording;
- the volunteer crosses the street two times to return to the starting point;
- a resting time is given to the volunteer.
The data recorded through Shimmer3 EMG and Shimmer3 GSR+ (http://www.shimmersensing.com/) are: electromyographic (EMG) signal, galvanic skin response (GSR) signal, temperature, blood pressure, inertial signals.
The devices are reported in the figures on the left side, with the volunteer's permission.
The project purpose is to analyse if there is a difference in a subject physiological response while he/she is listening to a heterogeneous audio playlist. This playlist is composed by tracks labelled as stressful or relaxing.
The experimental protocol is described in the following:
- 7 stressful and 7 relaxing audio tracks are randomly selected from a playlist;
- 150 seconds baseline recording;
- the volunteer listen to a 60 seconds track;
- 15 seconds are given to the volunteer to judge the track as stressful or relaxing.
The last two points are repeated for all the selected tracks.
The data recorded through Shimmer3 GSR+ (http://www.shimmersensing.com/) are: heart rate and GSR.
The project purpose is to analyse the subjective response of volunteers exposed to a heterogeneous experimental paradigm through means of electroencephalography.
The data are collected through the Unicorn Hybrid Black (g.tec medical engineering GmbH) using it with dry electrodes to assess the possibility of having more comfortable devices for electroencephalographic signal recording.
