Summary
This study shows that a touchless, sterile system using hand gestures and Kinect motion-capture technology is well-accepted by users for managing orthodontic models. High awareness of cross-infection correlates with greater acceptance for clinical use.
Area of Science:
- Biomedical Engineering
- Human-Computer Interaction
- Digital Health
Background:
- Evaluating a novel hand-gesture-based, touchless sterile system for interacting with 3D digitized orthodontic study models.
- Utilizing the Kinect motion-capture sensor for system control.
Purpose of the Study:
- Assess user acceptance of a touchless sterile system for orthodontic model management.
- Determine the correlation between cross-infection awareness and system adoption in clinical practice.
Main Methods:
- A cohort of 201 participants evaluated 7 hand-gesture commands using a validated questionnaire.
- Rasch analysis was employed to assess perceptions of gesture usefulness and acceptance.
- User perceptions regarding the system's value for cross-infection control were evaluated.
Main Results:
- The majority of participants found the hand-gesture commands accurate and generally accepted.
- A significant positive correlation was observed between participants' cross-infection awareness and their willingness to use the system.
- The system demonstrated potential for sterile patient record management.
Conclusions:
- The hand-gesture-based touchless sterile system shows promise for clinical adoption.
- User acceptance is high, particularly among those with greater awareness of cross-infection risks.
- This technology offers a viable sterile solution for managing digital orthodontic records.
