Ergonomic evaluation of 3D plane positioning using a mouse and a haptic device.

Area of Science:

• Medical technology
• Surgical navigation
• Human-computer interaction

Background:

• Accurate tumor surgery requires efficient preoperative planning and intraoperative assistance.
• Evaluating new tools for 3D spatial positioning is crucial for clinical adoption.
• This study investigated the efficiency and ergonomics of a haptic device versus a mouse for 3D plane positioning.

Purpose of the Study:

• To compare the performance and ergonomics of a haptic device against a mouse for 3D plane positioning.
• To assess the impact of force feedback on task efficiency and user experience.
• To identify optimal positioning strategies for integrating haptic devices in surgical applications.

Main Methods:

• An experiment was conducted comparing a mouse and a haptic device (with and without force feedback) for 3D positioning tasks.
• Key performance metrics included task completion time, number of 3D orientations, and failure rate.
• Participant ergonomics were evaluated using a dedicated questionnaire.

Main Results:

• The haptic device demonstrated a significantly lower failure rate compared to the mouse.
• Participants using the haptic device completed the task quicker and reported better ergonomics.
• The addition of force feedback to the haptic device did not yield performance benefits.

Conclusions:

• Haptic devices offer an intuitive, ergonomic, and more efficient alternative to mice for 3D plane positioning in surgical contexts.
• Understanding positioning strategies is key for successful integration of haptic technology into medical workflows.
• The findings support the use of haptic devices for enhancing precision in surgical planning and assistance.
