Noting of sensations is a very meditatively relaxing thing to do. At a high level it is very simple. Everyone continuously pays attention to the sensations they experience, and when it is their turn they say out loud what the sensation is.
Early on in the process, it is useful to limit descriptions to the six senses:
After people have gotten used to the act of noting things socially, you can open this up for more detailed descriptions. If you are sensing touch from a laptop, it could be noted as metal or smooth.
After each social noting session, talk with the participants about what they felt, what helped them get into flow and what brought them out of flow. The facilitator should make sure everyone who wants to say something gets to say it.
Repeat the five minute noting session and debrief twice in a session.
As a facilitator
In order to establish the positive intent of this session
Given a rough idea of the group you are leading for
When you establish the positive intent
Then you target the group with it
And let your positive intent guide the session
This is as simple as saying out loud or in mindvoice "With this group meditation session, I intend to help the group understand themselves" or similar. Adjust as needed based on the topicality of the group in question and the context of the world that day in general.
In a pinch just target them with metta.
As a facilitator
In order to help the group prepare for the meditation
When I am explaining this exercise
Then I will go over part of the instructions above
But make sure everyone understands what to do
As a meditator
In order to note sensations as a group
Given the timer has started
When it is my turn
Then I sense sensations
And I note the sensation I am experiencing
But if I can't give a word to it I pass
And it goes to the next person in order
As a facilitator
In order to help the group note sensations
Given everyone is ready
And I have established an order
And a timer is set for five minutes
When I start the timer
Then I sense for sensations
And I note the sensation
And the next person continues
As a meditator
In order to help the group understand the session
Given questions or experiences to report
When it is my turn
Then I ask my question or relay my experiences
And I help answer others questions when I can
# experiences when meditating are subjective, man
But I don't judge
And I don't interrupt
As a facilitator
In order to help the group understand the session
Given an order of people to ask
When you ask someone
Then you wait for them to reply
And tell us about their experiences
And if you have any insight that may help
Then you share it freely
