Abstract: The paper introduces Stripe, an interactive continuous scale for online surveys that makes it easy to compare multiple answers on a single screen. The Stripe is evaluated as an alternative to the n-point Likert scale, which is commonly used in online usability questionnaires like the System Usability Scale (SUS). The paper presents the results of a user study, which confirmed the validity of results gained with the proposed Stripe interface by applying both the Stripe and the Likert interface to an online SUS questionnaire. Additionally, the results of our study show that the participants favor the Stripe interface in terms of intuitiveness and ease of use, and even perceive the Stripe interface as less time consuming than the standard Likert scaled interface based on radio buttons.
