consent OSWeb
Hi,
I need to add a consent form with a checkbox in the beginning of the experiment; and I was wondering if there is any solution to adapt it to the OSWeb for a JATOS study since I just discovered that form items are not compatible.
Best,

Hi Hulya,
Here is some Python code to have an informed consent. Of course you would have to translate it to Javascript, which will be a challenge (if not impossible) as the mouse item cannot be used in javascript inline. But maybe you can use the code to wrap a loop with Opensesame items and the mouse item to mimic the same effect.
Here the code:
import os def drawX(cv,x,y,color): cv.line(x-14 ,y-14 , x+14 , y+14, color=color) cv.line(x-14 ,y+14 , x+14 , y-14, color=color) # create objects my_cv = canvas() my_mouse = mouse() my_cv.set_fgcolor('red') my_cv.set_penwidth(10) # image dimensions Iwidth = 1535 Iheight = 1151 #scale image onto screen im_scale = min(float(var.width)/Iwidth,1) new_dimX = Iwidth * im_scale new_dimY = Iheight * im_scale # relevant positions of important addons rel_Xcheck = 0.24 rel_Ycheck = 0.78 rel_Xtext = 0.14 rel_Ytext = 0.02 # The location of the checkbox x_check = -(0.5 * new_dimX - new_dimX * rel_Xcheck) y_check = -1 *( 0.5 * new_dimY - new_dimY * rel_Ycheck) # The location of the 'participant X' text x_text = - (0.5 * new_dimX - rel_Xtext * new_dimX) y_text = - (0.5 * new_dimY - new_dimY * rel_Ytext) # load image path = pool[u'InformedConsent_EN.png'] #print os.getcwd() # show canvas save = False while True: button, position, timestamp = my_mouse.get_click(timeout=20) #draw canvas with image my_cv.image(path,scale = im_scale) # draw participant no on top my_cv.text('subject'+ str(var.subject_nr), x = x_text, y= y_text) pos, foo = my_mouse.get_pos() if x_check - 10 < pos[0] < x_check + 10 and y_check - 10 < pos[1] < y_check + 10: drawX(my_cv,pos[0],pos[1],"green") else: drawX(my_cv,pos[0],pos[1],"red") my_cv.show() if button: if x_check - 10 < position[0] < x_check + 10 and y_check - 10 < position[1] < y_check + 10: save = True drawX(my_cv,position[0],position[1],"green") clock.sleep(500) break my_cv.clear() if save: baseDir = os.path.join(os.getcwd(),"../experiments/predictiveSwitchingIntention/InformedConsent") path = os.path.join(baseDir,'subject_no_'+str(var.subject_nr)+'.png') self.experiment.window.getMovieFrame() self.experiment.window.movieFrames[0].save(path)Hi Eduard!
Thank you very much for your response, and apologizes for my late answer.
I also would like to ask for a similar form problem: I need o get multiple keyboard inputs as responses in one sketchpad. Is it possible? I am using the solutions that were recommended before https://forum.cogsci.nl/discussion/6274/is-a-way-to-record-id-of-participants in here, but I couldn't seem to adjust it to my needs. Basically the form is something like this:
__ % of time I ...
__ % of time I... and so on. Participants need to enter 10 numbers like this in one form. But when I try the upper solution, the second response always takes the first one - I fixed this by logging different variables for the second (like var.percent1, var.percent2 ... etc = ' ' in the init phase) but then the second one does not take any input at all, and looks like I need to have 10 seperate blocks and sequences and inline scripts for every single answer. Is there a more elegant way to solve this? Here is a screenshot of how I am being ridiculous.
Best,
Hülya
Hi Hülya,
I assume you need this for OsWeb (even though you put it on the Opensesame forum). If you actually need it for offline Opensesame, there is no need to use javascript.
I don't think I understand your issue or your approach. Would you mind explaining again. Or if your problem is the same as you described here, let's try to keep the discussion central and not spread over multiple threads. That only makes things more confusing and messy. So, if these two problems are the same, let's talk in the other discussion.
