Discover a seamless way to participate in academic and scientific studies with Twente Intervention and Interaction Machine, a platform designed to support research participation in a clear, flexible, and secure way. When you open the app, you see a user-friendly home page with all studies you have joined, including each study’s title, short description, and end date, so you can easily keep track of your participation.

Joining a study is simple. Use the Add Study feature to scan a QR code or enter a unique five-character code. Once enrolled, you can complete study activities and questionnaires using a wide range of interactive formats, including text input, multiple choice, sliders, drag-and-drop, orbit/network visual questions, and quadrant scaling. The app also supports media-rich responses such as video, audio, graphical data, and photo uploads where required by the study.

You can review completed surveys at any time and manage your account through the options page, where you can edit your profile details, manage login settings, and adjust notification preferences. If you decide to withdraw from a study, you can do so easily at any time.

Important hardware requirement: some wellness-related study features rely on Samsung Health and a compatible external wearable device or smartwatch connected to Samsung Health. These features do not function independently without a supported external device and connection.
