Create response of swiping left, right, up and down

Radhika · August 2019

Hello!

I wanted to create an experiment where a word is shown on the centre of the screen and can be swiped right, left, up and down by the participant on a touch screen device. I have stored the words in the loop and used inline script to display the words on the screen using canvas. However, I need help about the the swiping response can be created in OpenSesame. Thanks!

Hi Radhika,

How far did you get already? How do you want the swiping to look? I think the most straightforward solution is to make the position of the stimulus dependent on the currently touched position. The basic approach could look like this:

ms = Mouse()
cv= Canvas()
cv['word'] = Text('someWord')
cv.show()
while True:
    b1,b2,b3 = ms.get_pressed()
    # if touch happened (and is being happening), get the current position and adjust the stimulus pos
    while b1:
        (x,y), time =  ms.get_pos()
        cv['word'].x = x
        cv['word'].y = y
        cv.show()
    # if stimulus was moved, stop trial
    if cv['word'].x != 0:
         break

Hope this helps. Let me know if you need more help.
