MO movement

VISTA SN behavior

r 1= r 2= r 3= 0

MO not present

No MO recognition done at SN

r 1 = r 2 > r 3

MO present but moving away

No MO recognition done at SN

r 1 > r 2 > r 3

MO present but moving away

No MO recognition done at SN

r 1 < r 2 > r 3

Come close and moving away

No MO recognition done at SN

r 1 = r 2 = r 3

MO stands still

MO recognition done only at that SN

r 1 < r 2 = r 3

Come close and stop

MO recognition done only at that SN

r 1 > r 2 < r 3

Come close and went away and come close

MO recognition done only at that SN

r 1 < r 2 < r 3

Moving towards and enter in RoI

MO recognition done over the entire network

r 1 = r 2 < r 3

Moving towards

MO recognition done over the entire network
