This study concerns the implementation of a gamified API in a digital human modelling simulation software, Industrial Path Solutions – Intelligently Moving Manikin (IPS-IMMA). The software has been identified as complex to learn and use, requiring a high level of expertise and involvement in order to interpret the interface and finding the correct tool for each task, causing disengagement from the users. To solve this issue, the study has looked into the concept of gamification to increase user activity by using elements and techniques from game design and applying them in a non-game context. Research on gamification in learning and training indicate increased engagement from the user, quicker on-boarding to a system as well as potential increases in learning outcome. The gamified API implementation in this project has the purpose of increasing user engagement when utilizing the tool, increase the retention rate of users, as well as smoothing the learning curve for the user, producing an optimal learning trajectory that will make the novice user become a skilled user within a shorter period of time. To achieve this, an API widget package has been connected to IPS-IMMA to create one of the first gamified interfaces for a digital human modelling software.
