I think the App could be a very valuable tool to facilitate tailored feedback to study participants. @Sebastian: Many thanks!!! Best wishes, Daniel Begin forwarded message: From: "Sebastian O.

Here is a short description of its core functionality: - User management: Users log in, and are shown the tasks currently unlocked for them. The IDs are managed via a back-end that is accesible via the browser - Tasks include: Screen recording, as well as any link that can be opened in a browser (will be opened in the app), such as for example a survey or an oTree experiment - The logic and sequence of the tasks (e.g., delayed by 1 week) can be configured in the back-end for a given study. A user can be assigned several studies - The screen recording can then be further analyzed using video language models, for which we have developed an AI Pipeline that runs on the high performance computing cluster of the Max Planck Society, and the content can then be further analyzed using e.g., cluster analysis or LLMs - Via the user management, reminders can be sent, and they are also sent automatically once a new task is unlocked or they are assigned another study The app is available both in the Apple app store for iOS as well as in the Android play store <https://apps.apple.com/de/app/mpi-coll-studien-app/id6746279893> <https://play.google.com/store/apps/details?id=de.hb.mpiapp> I'd be happy if that is of interest for a joint project! All the best and have a nice weekend, Sebastian
