3. Experiments
- Let the participant sit upright in the chair and place his right arm parallel on the table;
- Fix the measurement system to the front side of the arm and fix the airbag to the upper arm of the participant;
- Turn on the measurement system when the participant relaxes;
- Fifteen seconds later, inflate the airbag to press the upper arm;
- Fifteen seconds later, release the airbag;
- Turn off the measurement system.
- Let the participant sit in the chair and fix the measurement system onto their forehead;
- Turn on the system and let the participant close their eyes throughout the experiment;
- Ten seconds later, ask the participant to imagine walking upstairs;
- Forty seconds later, let the subject stop imagining and relax;
- Turn off the measurement system.
- Let the participant lie in the nap pod and fix the measurement system onto their forehead;
- Turn on the system and let the participant close their eyes throughout the experiment;
- Fifteen seconds later, ask the participant to breathe deeply or hold their breath;
- Thirteen seconds later, let the subject breathe normally;
- Turn off the measurement system.
