PSD WS 2018/2019: SPOT.ME Picture Quiz WebApp


The practice of software development in the winter semester 2018/2019 was dedicated to the implementation of a picture quiz as a web app with editor functions.

Our research group has been working on the topic of technology supported learning and serious games in particular for several years. Serious games are becoming an increasingly important element in the accompaniment of teaching or training, as they promise an improved learning experience and sustainable learning success. With this learning app, a training component for image evaluation is to be created and tested for effectiveness in the follow-up to the PSE project. Target groups of this training component are e.g. biologists (determination of animals and plants on images), remote sensing (determination of objects on satellite images), etc.


The goal is to implement a picture quiz with editor functions. The app should make it possible to quickly identify and name objects on pictures with other players. An editor allows players to create new tasks themselves.

Important cornerstones:

  • Cross-platform web application, e.g. as Progressive Web App (PWA). The quiz is therefore playable on all web-enabled platforms such as desktop PC, smartphone or tablet.
  • 2 game modes: solo game, duel
  • Modular architecture/data structure to extend and customize the app (e.g. new task types or additional game modes).
  • Gamification elements like leaderboards, achievements, scoreboards
  • "Community" editor for creating new picture puzzles. I.e. the players themselves can create and set new tasks. The focus in this project is mainly on the easy creation of new tasks and not on the consideration of a necessary editing (checking for correctness, etc.) of the new tasks. The editor also does not necessarily have to work on all end devices. A desktop version is sufficient.
  • Client Server Architecture; Software Patterns
