A while-loop is used in this function to refresh the needle when it is moved around. It's not very difficult to add a few lines that will save the needle position periodically. The modified attachment should do something like that. The 1-sec positions are now saved as attribute with incremental suffix (xyz.1, xyz.2 etc.). Another option would be to force logging at each interval by inserting a call to c.Log. In that case it is not required anymore to add the suffix, so all results would be inserted into the same xyz column of the output file. However, you will get more rows instead of columns.</div>

<br>I'd like to implement some form of Paul Groot's visual analog scale, but what I would like eprime to do is record the position on the scale every second or so. <br>So let's say the participant was letting his mind wander, and was continuously moving the scale up and down according to how they were feeling, and then<br>
having ePrime log wherever the indicator is on the scale. What would be the easiest way to go about doing this? I don't know if the scale treats the indicator<br>as a mouse cursor or what, so I'm a little clueless what to do. <br>
<br>Thanks in advance for your help! <br><span><font color="#888888"><br>-Matt <br></font></span></div><span><font color="#888888">
