Txhawm rau xa cov lus ua tiav mus rau lub khoos phis tawj, lub joystick yuav tsum ntsuas nws txoj haujlwm ntawm ob lub axes: X-axis (los ntawm sab laug mus rau sab xis) thiab Y-axis (los ntawm sab saum toj mus rau hauv qab). Raws li nyob rau hauv cov duab geometry, X-Y kev tswj xyuas qhov tseeb qhia qhov chaw ntawm lub joystick.
Nyob rau hauv tus qauv joystick tsim, lub gamepad txav ib tug nqaim pas nrig mounted ntawm ob rotatable slotted axes. Tsiv lub joystick rov qab los tig lub Y-axis ntawm ib sab mus rau lwm qhov. Tsiv nws sab laug thiab sab xis tig X-axis. Tsiv lub joystick diagonally tig ob axes ib txhij. Thaum koj tso lub joystick, ob peb lub springs rov qab mus rau nws qhov chaw nruab nrab.
Lub joystick tswj qhov system tsuas yog yuav tsum tau saib xyuas txoj haujlwm ntawm txhua qhov axis los txiav txim siab lub joystick txoj haujlwm. Tsoos analog joysticks ua tiav qhov no siv ob qhov sib faib hluav taws xob lossis qhov sib txawv ntawm cov resistors.
