Perceptions of the machine learning-based lower-limb exercise training system (N = 94).
| Very strongly disagree, n (%) | Strongly disagree, n (%) | Disagree, n (%) | Neutral, n (%) | Agree, n (%) | Strongly agree, n (%) | Very strongly agree, n (%) | |
|---|---|---|---|---|---|---|---|
| Using the system would improve my performance in lower-limb exercises | 0 (0) | 0 (0) | 3 (3.2) | 18 (19.1) | 55 (58.5) | 12 (12.8) | 6 (6.4) |
| Using the system would increase my chances of improving knee health | 0 (0) | 0 (0) | 4 (4.3) | 16 (17.0) | 55 (58.5) | 14 (14.9) | 5 (5.3) |
| The system would promote my adherence to lower-limb exercises | 0 (0) | 1 (1.1) | 4 (4.3) | 18 (19.1) | 51 (54.2) | 15 (16.0) | 5 (5.3) |
| Learning to use the system would be easy for me | 0 (0) | 0 (0) | 2 (2.1) | 6 (6.4) | 58 (61.7) | 24 (25.5) | 4 (4.3) |
| It is a good idea that the system has lower-limb exercise videos instructed by a physical therapist | 0 (0) | 0 (0) | 2 (2.1) | 7 (7.4) | 53 (56.4) | 19 (20.3) | 13 (13.8) |
| It is a good idea that the system has real-time movement feedback on performance of lower-limb exercises | 0 (0) | 0 (0) | 2 (2.1) | 5 (5.3) | 60 (63.9) | 14 (14.9) | 13 (13.8) |
| It is a good idea that the system would track my exercise progress | 0 (0) | 0 (0) | 2 (2.1) | 16 (17.0) | 50 (53.2) | 17 (18.1) | 9 (9.6) |
