Area of Science:

  • Medical Informatics
  • Human-Computer Interaction
  • Surgical Technology

Background:

  • Computer-assisted surgery (CAS) systems are increasingly important for clinical outcomes and ergonomics.
  • Effective evaluation protocols for human-computer interaction (HCI) in CAS are crucial but often lacking.

Purpose of the Study:

  • To establish criteria for designing effective evaluation protocols for HCI in CAS systems.
  • To assess the usability and efficacy of HCI in CAS through a structured evaluation framework.

Main Methods:

  • Development of author-created questionnaires to assess surgeons' subjective experiences and objective system aspects.
  • Iterative or end-of-development submission of questionnaires to end-users and HCI experts.
  • Quantitative evaluation of key surgical application parameters to measure system efficacy.

    • Main Results:

    • The evaluation procedure provided valuable insights into the HCI efficacy of the TKR planning software.
    • Indications for further design and functional enhancements of the CAS system were identified.
    • The approach demonstrated the utility of the proposed evaluation for CAS development.

    Conclusions:

    • The proposed HCI evaluation procedure is effective for CAS systems, as shown with TKR planning software.
    • This methodology can guide improvements in the design and functionality of CAS systems.
    • Similar CAS applications, including surgical training and navigation platforms, can benefit from this HCI evaluation approach.
