Therefore, I was wondering whether there is a variable that I can record that can differentiate between subjects using a computer mouse or a touchpad on their laptop. Since the /inputdevice option ‘mouse’ allows for recording both.<br/><br/>Also, can Inquisit record the default mouse speed that might differ between subjects in an online experiment? Or disable mouse acceleration in case it is on? I guess the answer is no, however, I was still wondering whether there is a possibility to standardize the mouse speed during the Inquisit experiment.<br/><br/>Thanks for your input,<br/>–P<br/>Thu, 18 Feb 2021 12:26:55 GMTpeter.k.phttps://forums.millisecond.com/Topic30848.aspx<blockquote data-id="30846" class="if-quote-wrapper" unselectable="on" data-guid="1613651095515" id="if_insertedNode_1613651094406" contenteditable="false"><a class="quote-para" unselectable="on" style="display: none;" href="#" data-id="30846" title="Move Cursor Below" contenteditable="false"><span unselectable="on">+</span></a><a class="quote-delete" unselectable="on" style="display: none;" href="#" data-id="30846" title="Delete Quote" contenteditable="false"><span unselectable="on">x</span></a><span unselectable="on" class="quote-markup">[quote]</span><div unselectable="on" class="if-quote-header" contenteditable="false"><div unselectable="on" class="if-quote-toggle-wrapper"><a class="if-quote-toggle quote-link" href="#" data-id="30846" title=" ">&nbsp;</a></div><span unselectable="on" class="quote-markup">[b]</span>peter.k.p - 2/18/2021<span unselectable="on" class="quote-markup">[/b]</span></div><div class="if-quote-message if-quote-message-30846"><div class="if-quote-message-margin" contenteditable="true">Hello Everyone,<br/><br/>It is crucial for online mouse tracking research to only accept mouse input and not touchpad input.

However, you could have participants indicate what they use at the very beginning of the procedure and then abort for those that indicate touchpad.Thu, 18 Feb 2021 12:26:55 GMTDave
