Initial position of the cursor

Hi, I am trying to set up the starting position of the cursor for joystick so that it can show up randomly each time when a new condition is run. Is there a way I can do this? Thank you.

Have you checked the "task\runtime v1\8 customized calibration" example? For joystick, you can use JoyCal or Joy2Cal.

new_origin = [3 3];
JoyCal.custom_calfunc(@translate_joy);
...
...
...
function xy = translate_joy(xy)
    n = size(xy,1);
    xy = xy + repmat(new_origin,n,1);
end

I just wrote the above code off the top of my head, so compare it with the "8 customized calibration" example and make any necessary change. You can perturb the calibration in any way you want.

Hi Jaewon,

Thank you so much for your help, I updated my script and it works pretty well!
I did saw the customized calibration file but just had a hard time to make cursor start moving after setting it up.

I have another question want to ask:

Is there a way I can updated my Target picture to a different picture? For example, after the delay period, two images are presented on both sides of the screen (blue circle and red circle), and when the subject operates the joystick to chose the blue circle, which is target here, I can update a green circle picture to replace the blue circle immediately to indicate success before the picture disappears.

Create two circles (blue and green). Then, when the blue circle is chosen, turn it off and turn on the green one.

Found the way to do that, thank you!
