Mobia Modeling Framework

  • Mobia Modeling Tool

– Allow non-expert users to easily create mobile applications by modeling the mobile application and having a tool automatically transform the model to code

  • Easy to learn
  • Feature modeling constructs that are intuitive

– Extend to different application domains

  • Current focus: Mobile Health Monitoring

Modeling User Interaction

  • Given

– Medget Instances: A, B, C – Medget Data: x, y, z, a, b – Actions: Choose, Drag, Drop, Click, Connect

  • User’s Goal

– Select the Medget A and the MedgetData x
