A style of spinning where the center of...I assume it would be called gravity is no longer directly in the handle but somewhere on the string, preferably the middle of the body (string).

A style of spinning where the centre of rotation of the poi is located halfway between the poi handle and the poi head rather than at the handle.

word..

But you can isolate things so the center of the poi is not the center of rotation, like in Matt's little flash program.

True, but that's a variation. Or when you can't do it properly Sphism/gigglesmiley

The term isolation make me think what were doing is a varation. I think a true isolation would be hands going around the poi head.

Yeah I suppose so. But if you're doing things like isolated weaves and so on the centre of rotation has to be in the middle... if it wasn't then gravity would cause problems Sphism/winksmiley

the way isolations were explained to me is that youre giving the poi an elliptical orbit in order to kill the momentum and centripetal force. this definition works except in the case of a true 50% isolation... but then id say it would be elliptical, except you compensate to make it more circular. the physics behind it are the same. irregular orbit.

hmm, you only get an ellipse by shifting the centre of rotation up and down the poi. That'd be a cool thing to do on purpose.

(i've played with various orientations of ellipses with stick, but not with poi cos they're harder to isolate...)

but 'isolations' as i've come across them on boards and in real life are intended to be pherfectly spercular (or perfectly circular, depending... :winkSphism/smilesmiley

Of course, all my isolations are a little ellipticalwobbly really, cos i aint perfect :oops:

i'll repeat my opinion that it makes sense to lump all 'centre of rotation' terminology together.

Poi-Based

Full Isolation - Poi Head

Three quarter isolation - one quarter down poi length

Isolation (should really be called a half isolation) - Centre of Poi

Quarter isolation - one quarter down poi length

Ordinary Circle Hand circle - Poi handle

Body based

Ordinary Circle Hand circle - Hand (in both categories)

Elbow circle - Elbow

Arm Shoulder circle - Shoulder

You can have a poi based AND body based centre of rotation at the same time.
for example: Snakes are isolations AND elbow circles

Also, you can expand the body based definitions as you want...

Hand+Hip circle - centred on the hip, like 'reels'

Hand+Head circle - centred on the head AKA Poindexters.

Elbow+Head circle - elbow on head, poi rotating as an elbow circle around head AKA Elephant moves Sphism/coolsmiley

Lots of long words in there. Sphism/gigglesmiley Brain is tilting again, ah well.

that head/foot/toe/tongue stuff doesnt make sense to me... ok.. now it does.. I just had to think a second.. where the rotations is.. hand being center for normal circles.. lbow can be the scenter..and shoulder center like during giant sutff.. aight..

but I agree with the half isolation.. that was one of the prblems I had when learning one.. because the way itwas described the hand should make full circles while the poi stays in the center.. which is a full isoaltion, takes hella isolability on the part of the spinner..

yup hella isobility definitely required.
i've only seen full isolations done for half a beat, and never seen a really clean one.
(ok, you can do them with throws, but thats cheating :winkSphism/smilesmiley

see that's what I understood an isolation to be.. so I didn't mess with them at all.. until I glanced over mot's page one day.. and was like wait a minute..

Ok, so using Simian's

Isolation:

The moving of the centre of rotation to a differant point as follows

Poi-Based

Full Isolation - Poi Head

Three quarter isolation - one quarter down poi length

Isolation (should really be called a half isolation) - Centre of Poi

Quarter isolation - one quarter down poi length

Ordinary Circle Hand circle - Poi handle

Body based

Ordinary Circle Hand circle - Hand (in both categories)

Elbow circle - Elbow

Arm Shoulder circle - Shoulder

You can have a poi based AND body based centre of rotation at the same time.
for example: Snakes are isolations AND elbow circles

Shouldn't we just link isolation to the "Centre of rotation" definition which already has all of these defined?

Woah I didnt even remember that one

Just looked at it I see what you mean... I'd say so. Also a link to some isolation vids Sphism/winksmiley

Welp okies
