Hi,
I was wondering whether it is possible to send log events to Tobii Studio in a recurrent way, while presenting a stimulus. This would be to facilitate the chopping up into scenes (using the automatic scene generation in studio, from the events sent directly by e-prime) and thus the visualization of the data in Studio.
The events for example would be sent every 1 or 10 seconds (user defined), and could then be used to divide the recording in Studio into scenes of that length, automatically.
Thank you for any input you might have!
Best regards,
Leopoldine Brand

I would take a look at the process responses sample that PST offers on their site (attached). Basically it is a way to run script while an object/stimulus is on screen. You set the object up with a 0 duration and set the end action to none and then in an inline you have a loop that runs until whatever criterion you want (response, specific amount of time). For this, you would just have script inside the loop to run CVSendLogEvent calls.
This would be the script for sending a log event every second while the Stimulus object is on the screen:
Dim nStartTime As Long
Dim nNextTime As Long
Dim nCount As Long
nStartTime = Clock.Read
nNextTime = nStartTime + 1000
Do While Stimulus.InputMasks.IsPending()
If Clock.Read >= nNextTime And nNextTime = (nStartTime + 1000) Then
nCount = nCount + 1
strSceneName = "SceneStart Scene" & nCount
CVSendLogEvent(c, strSceneName)
nNextTime = nNextTime + 1000
ElseIf Clock.Read >= nNextTime
Dim strSceneName As String
strSceneName = "SceneStop Scene" & nCount
CVSendLogEvent(c, strSceneName)
nCount = nCount + 1
strSceneName = "SceneStart Scene" & nCount
CVSendLogEvent(c, strSceneName)
nNextTime = nNextTime + 1000
End If
Loop
This just uses a counter to name each scene Scene1, Scene2, Scene3. The two If statements are to make sure that on the first time, since there is no active scene, a SceneStop event is not sent. Otherwise, we send a SceneStop (current scene) event and then a SceneStart (next scene) event.
This works best if there is only one object in the experiment that you want to send multiple events for. If there are multiple objects, unfortunately you will have to use this script on all of them, which can become a pain.

Hi,
Thank you very much for the quick and detailed answer! I didn't know one could run a script in parallel, but I will try it out immediately!
Best regards,
