DirectIN Rotary Controller on Mac OS 10.10 (case 19155)

[JEC]

Ah. We were hoping to integrate it with psychopy. Knowing that it acts as a joystick instead of a keyboard should make it easier to get the correct python packages to access it. Thank you very much.

Just curious - have you had any luck using the controller with your software?

Yes. There were some issues, but they had to do with the software's joystick integration in general as opposed to an empirisoft specific problem.

Would you mind giving some more information regarding how you got this set up to work? I just purchased the DirectIN Rotary Controller with the intention of using it in PsychoPy2 as well, and so far I cannot get the program to recognize it. Thanks in advance.

Sure. I had to manually create the joystick object using pyglet, instead of using the PsychoPy joystick functions. See the code below for a minimal working example.

import pyglet
joysticks = pyglet.input.get_joysticks()


for joy in joysticks:
    if joy.device.name == 'Analog Scale Device':
        joy.open()
        break

def present_pair_joystick(trial,isi,curdata): #trial is a sound object, isis is the time to wait after response/end of sound, and curdata is a dictionary used to store response data
    event.clearEvents()
    while joy.buttons[0] or joy.buttons[1]:
        continue
    curdata['trial_start']=time.time()
    trial.play()
    dur = trial.getDuration()
    while True:
        if not (joy.buttons[0] and joy.buttons[1]):
            if joy.buttons[0]:
                curdata['rt'] = time.time() - curdata['trial_start']
                curdata['resp'] = 'Word'
                break
            elif joy.buttons[1]:
                curdata['rt'] = time.time() - curdata['trial_start']
                curdata['resp'] = 'Nonword'
                break
            if 'escape' in event.getKeys():
                core.quit()
    if time.time() - curdata['trial_start'] > dur:
        core.wait(isi)
    else:
        core.wait((dur - (time.time() - curdata['trial_start'])) + isi)
    curdata['dur'] = dur
    return

Hope that helps.

Thank you for your reply. I am trying got conduct a two-alternative forced choice experiment. I was under the impression that this button box worked like a keyboard, not a joystick. Unfortunately I don't have a lot of experience outside of the builder view. Do you think it would be possible to use your code in a custom code snippet inside one of my trials? In other words I could replace the keyboard response component with a custom component. I tried this without any luck so far. Thanks again for any help.

Sorry, I'm not experienced with the builder view, so I'm not sure exactly how to go about implementing it. It should be possible to set up something with coding custom code snippet. I'd get in touch with the PsychoPy community and ask about how to implement joystick input in the builder view. Best of luck!

Hi,

I purchased the DeirectIN rotary controller. I use E-Prime (it's what me department has), and while the PCs I use for my experiments recognize the device, E-Prime refuses to recognize the device. Their troubleshooting guide indicated that I require a .dll file to force E-prime to recognize the device (see: https://support.pstnet.com/entries/9...E-Prime-19547-).

Is such a file available? Thanks!

Sure. I had to manually create the joystick object using pyglet, instead of using the PsychoPy joystick functions. See the code below for a minimal working example.

def present_pair_joystick(trial,isi,curdata): #trial is a sound object, isis is the time to wait after response/end of sound, and curdata is a dictionary used to store response data
    event.clearEvents()
    while joy.buttons[0] or joy.buttons[1]:
        continue
    curdata['trial_start']=time.time()
    trial.play()
    dur = trial.getDuration()
    while True:
        if not (joy.buttons[0] and joy.buttons[1]):
            if joy.buttons[0]:
                curdata['rt'] = time.time() - curdata['trial_start']
                curdata['resp'] = 'Word'
                break
            elif joy.buttons[1]:
                curdata['rt'] = time.time() - curdata['trial_start']
                curdata['resp'] = 'Nonword'
                break
            if 'escape' in event.getKeys():
                core.quit()
    if time.time() - curdata['trial_start'] > dur:

    else:
        core.wait((dur - (time.time() - curdata['trial_start'])) + isi)
    curdata['dur'] = dur
    return
