Avoid havin g only pl ain- colored sur faces in

Move the devi ce slowly a nd constantly. Avoid jerky movements. Fast
and jer ky moveme nts may le ad to
inaccurate data and tracking may
be lost. Avoid ca pturi ng longe r

so that the V ideo View
and the vi ew in the sm all wi ndow match.
Then, a g reen and red c ross-s haped ico n

Ambient light conditions
In scenes w ith too bright il lumi nation (cl ose
