Abstract
Onni is a toolbox created for online experiments. You can think it as a merger of super simple E-prime or Presentation and hassle-free Webropol / Google docs that can also handle bodily sensation mapping (emBODY measurements). It is geared towards getting fast ratings for video / audio / image / text stimuli and setting up simple questionnaires, but is easy to customise towards other uses too. Setting up experiments is really fast. Web-based user interface with simple formatting options and batch stimulus upload & questionnaire generation allows deploying studies in minutes. Data are stored centrally and accessible. Onni is a Flask app using MariaDB. In short, main functionality includes setting up stimulus rating experiments with the following format: A page for experiment instructions Background questions screen with multiple choice dropdown-menus Actual rating of stimuli (Audio, Video, Text or Images) Rating of stimuli is done with sliders that store values between 0-100 or with an emBODY-tool (Nummenmaa et al., 2014) Reference: Bodily maps of emotions Lauri Nummenmaa, Enrico Glerean, Riitta Hari, Jari K.
