This is the extended version of the (fake) metal detector for your next "Cops and Robbers" or "Murder Mystery"
The selected contraband image appears gradually and a sound can be heard when you
reach the horizontal holding position of the iPhone or iPod touch while "wanding" a person with it.
(With a bit of practice you can determine where the contraband seems to be hidden.)
The horizontal holding position can be calibrated and left-handed usage (the
home button shows to the holding hand) or right-handed usage (home button shows
away from hand) can be set in an option-screen.
This screen also allows to select the image of a small gun, a pocket knife or the "not allowed" sign from the simple version
of "iWand" as standard contraband image.
An intensity-meter shows the detection strength of the hidden object as a value
from 0 to 100 percent.
Alternatively you can use the built-in backscatter-screening simulator which shows the simulated scanning progress (0 to 100 percent).
under usual conditions it is sufficient to connect earphones to a first generation iPod Touch
in order to hear the sound in the vicinity of the device, but in a louder environment
external speakers are recommended.
