“The programmer, like the poet, works only slightly removed

from thought-stuff.

He builds his castles in the air, from air,

creating by exertion of the imagination.”

A sunburst visualization that shows activities and time componentsA tree visualization of the entities involved in the last session with the intensity of the interactions

An activity view that decomposes a single activity into its low-level events

A summary of the developer’s profile that goes towards an application of gamification

A sentiment feedback on the last development session

A timeline of activities, divided per category

A table that shows the last diffs

Session Digest A short-term gratification, similar to the one present in fitness apps, offered to developers for their last development session. It summarizes the last session from various perspectives, e.g., how was time used, how much was achieved from a coding point of view, which program entities were involved, etc. It also enables to dig into the fine-grained recorded data and acquire a deeper understanding.

Alter Ego A developer is like a character in a role-playing game: She moves her first steps, evolves, acquires new skills, and unlocks new ach ievements . In our v i s ion developers possess an avatar that they can evolve, providing them short- and long-term satisfactions to turn software development into a more engaging activity.

Development Empire The long-term vision is a comprehensive gamification layer on top of the IDE. It is not all about assigning points to developers, but the development of a ramified system that rewards complex actions and best practices of a developer with badges, achievements, and trophies. The history and the evolution of the alter ego of a developer is a key factor. When this mechanism is in place, all the alter egos will originate a new community, where people can observe, challenge, and interact with other developers.
