Abstract
The present paper describes VAS Generator (http://www.vasgenerator.net), a free Web service for creating a wide range of visual analogue scales that can be used as a measurement device in Web surveying and Web experimentation, and also for local computerized assessment. A step-by-step example for creating and implementing a visual analogue scale with visual feedback is given. VAS Generator and the generated scales work platform-independent, the underlying languages are HTML and JavaScript.
The VAS generator greatly reduces the effort needed to use VAS in online surveys. It provides all files needed for the use of VAS and offers a preview function. VAS that are built by means of the VAS generator can easily be included in existing projects (e.g. in a Web experiment created with WEXTOR).
