摘要:
The control device (10) of a configurable audiovisual effect comprises: - means for generating at least two optical paths traversed by non-parallel light beams (110a and 110b), comprising at least one optical sensor (115) and at least one emitter (105a or 105b) of at least one light beam, - means for measurement (145) of the speed (150) of an object crossing at least two light beams, as a function of a signal (120) from at least one optical sensor representing the cutting of the optical paths by the object, - means for estimation (125) of the longitudinal position (130) of the trajectory of the object as a function of a signal from at least one optical sensor, representing the cutting of the optical paths of at least two non-parallel light beams by the object and - control means (135) referred to as "positional control means" of a parameter value (140) of an audiovisual effect as a function of the estimated longitudinal position.
