[http://limesurvey.org LimeSurvey] is a popular open source system for making and publishing surveys. All students and staff of the Faculty of Social Sciences can use it.  
+
The Radboud Immersive Virtual Environment Research (RIVER) Labs are two Behavioral Science Institute research labs dedicated to experiments in Virtual Reality (VR). However, in 2013 it was decided to make RIVER Lab 1 available for other purposes as well, promoting RIVER Lab 2 as the prime facility for any VR research. The RIVER Labs are managed by [[Erik van den Berge]] of the TSG.

Log on to [https://survey.socsci.ru.nl/index.php/admin survey.socsci.ru.nl/admin] with your university number and password to make a survey. Invitations to surveys can be send with a direct link to the survey (e.g. ''[http://survey.socsci.ru.nl/687521 survey.socsci.ru.nl/687521]'') or by referring to the main survey page ''[http://survey.socsci.ru.nl survey.socsci.ru.nl]''. Note that in the latter case the participant has to find the survey in a list. By default surveys are not listed on the main page. Change this in the ''survey settings'' if you wish. The preferred way is using direct links.

−
A similar trick as we used with the h.264 video is also possible to let text disappear after a while. Type some text, click the ''source'' button. Let's assume it looks like this:
+
<references />
−
 
 
−
Following text disappears after five seconds:&lt;br/>
 
−
Roses are red, violets are blue, I am gone, and so...
 
−
 
 
−
now change it into the following:
 
−
 
 
−
Following text disappears after five seconds:&lt;br/>
 
−
&lt;div id="question17">
 
−
  Roses are red, violets are blue, I am gone, and so...
 
−
&lt;/div>
 
−
<script type="text/javascript">
 
−
  setTimeout("document.getElementById('question17').style.visibility='hidden'", 3000);
 
−
</script>
 
−
 
 
−
Make sure the id (''question17'') is unique on the question page. It must appear precisely twice (as shown above). The 3000 is the time before the text disappears in ms. Try it in [https://survey.socsci.ru.nl/index.php/615263?lang=en demo time].

== FAQ ==
 
−
;Does TSG support the making of surveys?: No. Survey design is considered a core competence of social scientists, not in the domain of technical support. Ask Social Sciences scientific staff to assist in the making of surveys.
 
−
;Does TSG support the use of LimeSurvey?: No. Limesurvey does come with a [http://manual.limesurvey.org/ manual] and [http://www.limesurvey.org/en/community-services community] support. It may be covered in some courses as well.
 
−
;Does TSG support the data analysis of LimeSurvey?: Data analysis is your own responsibility.
 
−
;Does TSG store data collected with LimeSurvey?: Data must be collected from the LimeSurvey server as quickly as possible. Survey and data will be removed automatically one year after survey creation.
 
−
;I understand the answers above, but still want to ask a question. Where do I go?: [https://organisatiegids.ru.nl/tabProfiel.aspx?isEngels=true&RBSID=636916 Chi Lieu] is system administrator.

;What version is installed?: The version installed is 2.05+build141113 with patch #225 for automatic user creation. LimeSurvey may be upgraded without notification.

The Radboud Immersive Virtual Environment Research (RIVER) Labs are two Behavioral Science Institute research labs dedicated to experiments in Virtual Reality (VR). However, in 2013 it was decided to make RIVER Lab 1 available for other purposes as well, promoting RIVER Lab 2 as the prime facility for any VR research. The RIVER Labs are managed by Erik van den Berge of the TSG.

In RIVER Lab 2, five retro-reflective markers are attached to the Head Mounted Display (except HTC Vive) via a custom 3D-printed frame for tracking the participant's position and orientation; any internal tracking in the HMD is disabled.

Vive

As of November 2016, standard HTC Vive setups are available in both RIVER Labs. These setups use the Vive's own "Lighthouse" tracking system instead of the lab's, and a standard Lab Computer (with upgraded graphics card). No wireless solution is available for the Vive (yet), so the tracking area is limited by the length of the cable and the range of the Lighthouse tracking system. As of September 2017, the Vive in RIVER Lab 2 has been equipped with the Deluxe Audio Strap, which has built-in headphones.
