Abstract
Inventia se refera la un aparat pentru dezvoltarea perceptiei ariei cercului, destinat demonstratiilor didactice, selectiei profesionale si antrenamentelor sportive. Aparatul este compus dintr-o sursa de lumina proiectata pe un ecran de catre un subansamblu proiector deplasabil prin intermediul unui subansamblu ajustor format dintr-un cursor, un surub si un buton, astfel încît subiectul prin manevrarea butonului, sa regleze imaginea formata pîna cînd devine egala cu un cerc etalon fixat pe carcasa aparatului, eroarea de apreciere a egalitatii celor doua suprafete fiind data în milimetri de catre un subansamblu indicator.The invention relates to a device for developing the circle area perception, intended for teaching demonstrations, professional selection and sports training. The device consists of a light source projected on a screen by a movable projector subassembly by means of an adjustable subassembly consisting of a cursor, a screw and a button so that the subject by manipulating the button adjusts the image formed until it becomes equal to a calibration circle fixed to the instrument housing, the error of equation of the two surfaces being given in millimeters by an indicator subassembly.
