Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The maximum projected translational deviation between the executed and planned trajectories between AR-based and conventional navigation methods. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. The angular deviation of the conducted and planned trajectories compared between AR-based and conventional navigation method. 2. The depth deviation of the conducted and planned trajectories compared between AR-based and conventional navigation method. 3. Comparison of the total time between AR-based and conventional navigation methods. a. Sub-analysis 1: Time to reach the entry point (criteria: reaching 3 mm lower than the top surface of the block). b. Sub-analysis 2: Time to perform the drilling. 4. NASA-TLX workload comparison between AR-based and conventional navigation methods. 5. SUS usability comparison between AR-based and conventional navigation methods. 6. Qualitative comparison of AR-based and conventional navigation methods using Likert questionnaires. | — |
