Automatic Usability Engineering Methods


Optimized usability engineering of interactive services by usability prediction

Motivation & Project Description

  • State-of-the-art usability measurement methods still involve subjective tests with human participants, which come late in the service development cycle and at a high expense.
  • The aim of this project is to provide usability estimations for multimodal interactive services on the basis of algorithmic models, including

    • Models of human behavior during the interaction
    • Models for predicting usability problems (e.g. ISO 9241)
    • Models for predicting user judgments and hedonistic quality aspects

  • This way, services can be developed much quicker and cheaper.

Expected Outcome:

  • Models for describing user behavior in response to the service

    • Parameters for quantifying user/system behavior in multimodal interaction (input parameters to models)
    • Models of user interaction behavior for GUIs and VUIs
    • Identification of relevant quality aspects and their interrelationship
    • Models for predicting usability aspects and user judgments on the basis of interaction parameters
