'x-chopper'


x-chopper is a collaborative project by inon rettig, boaz mendel and arthur brutter from
jerusalem, israel. completed as part of their third year studies at bezalel academy of arts and design,
the concept behind x-chopper is based on their childhood memories of flying.

'back then, before flight simulators and video games, all we needed to do to fly was spread
our hands out wide, close our eyes and run around the house imagining we were in a plane
gliding high above'- IR, BM and AB





demonstration of 'x-chopper'



algorithm used to control 'x-chopper'
two hand down: off
two hands up: full power
six mid positions between off and full power
right hand up and left down: full power left
left hand up and right hand down: full power right
six mid positions between left and right


thinking of ways to translate these childhood dreams of flight into an interactive
project, they decided to alter the joystick of a toy helicopter so that it could instead
be controlled through the motion of spreading one's hands and 'flying'.






in the production of 'ex-chopper', the movement of the joystick is translated into an
accelerometer using a simple algorithm. for instance, two hands down
translates to an off command, while two hands up indicates full power. there are six
mid positions between off and full power. the accelerometers are implanted within
special gloves. the 'brain' of the controls is strapped around the waste.
