Clickable mouse response for multiple choices (on sketch pad)
Hi folks,
I am designing a linguistics experiment. I will present an image on the screen and underneath the image are 4-5 options to choose from. I want my participants to use pc mouse and click on the correct option. Any advice for a beginner like on how to do this is hugely appreciated. I tried the item form_multiple_choice but I don't think it allows me to put an image in it.
Kind regards,
Sam

Hi Sam,
I think there are several options:
1) You can use the form base plugin to design a custom form (see documentation here: http://osdoc.cogsci.nl/3.1/manual/forms/custom/). It also allows you to use images (http://osdoc.cogsci.nl/3.1/manual/forms/widgets/image/) and image buttons (http://osdoc.cogsci.nl/3.1/manual/forms/widgets/image_button/). However, you cannot use a graphical interface to design your screen but you can design it using the OpenSesame script syntax via the form base plugin (or you can use Python code directly).
2) If you would like to design your screen using a sketchpad item, you can use the mousetrap response plugin to define buttons on the screen and to collect the mouse response (see documentation here: https://github.com/PascalKieslich/mousetrap-os/blob/master/plugins/mousetrap_response/mousetrap_response.md#making-sketchpads-interactive). It also continuously logs the mouse position (as it is mainly designed for creating mouse-tracking experiments), but you can simply uncheck this option if you do not need the data. The installation of the mousetrap plugin is simple and described here: https://github.com/PascalKieslich/mousetrap-os#installation
Best,
Pascal
