Face recognition technology has lately attracted considerable attention because of its non-intrusiveness, usability and applicability. Related companies insist that their commercial products show the recognition rates more than 95% according to their self-testing. But, the rates cannot be admitted as official recognition rates. So, performance evaluation methods and tools are necessary to objectively measure the accuracy and performance of face recognition systems. In this paper, I propose a reference model for biometrics recognition evaluation tools, and implement an evaluation tool for the face recognition system based on the proposed reference model.

The increased competition in service development in various industrial sectors highlights the importance of producing high-quality services that provide a positive user experience. Although usability evaluation is recognized as an important method of verification of high quality service and utility, the general usability evaluation method has limitations of not taking the characteristics of various participants due to its uniform composition to account. As the following flaws can reduce evaluation efficiency, developing a new guideline seems to be the next step. Thus, this study focused on criteria on how to evaluate the usability for children and proposed non-face-to-face remote usability evaluation configurations and progress guidelines to increase the effectiveness. The following usability evaluation experiment was conducted based on the proposed guidelines and in this process, the effectiveness of the guidelines was verified and the items that needed to be supplemented were derived. It is expected that the non-face-to-face remote usability evaluation guidelines proposed through the study will be used as the basis for designing usability evaluations of services developed for children.

Objective: The study examined the validity and reliability of tele-assessment of cervical range of motion (ROM) through video conferencing. Design: A cross-sectional study Methods: The study included 22 healthy adults as subjects and 10 physical therapists as evaluators. The subjects underwent both face-to-face and tele-assessment of cervical ROM. The CROM (Cervical Range of Motion) device was used for reference measurements in the face-to-face assessment. The evaluators assessed the subjects' ROM through visual inspection (VI) and using a Universal Goniometer (UG) in the tele-assessment. Results: The results showed a significant correlation between the face-to-face and tele-assessment measurements for all ROM contents. The correlation coefficients ranged from r=0.54 to 0.71 (p<0.05), indicating concurrent validity. In terms of inter-rater reliability, the ICC values for both VI and UG assessments in the tele-assessment were high, with ICCs of 0.93 and 0.92, respectively. Additionally, the study investigated the usability of the tele-assessment method and environment. The satisfaction of the participants and evaluators was assessed using the Telehealth Usability Questionnaire (TUQ), which evaluates perceptions, usability, and satisfaction with telehealth services. Conclusions: In conclusion, tele-assessment of cervical range of motion using video conferencing was valid and reliable. Also, investigated participant and evaluator satisfaction and opinions, providing insights into the clinical value of tele-assessment. It is important to note that the study was conducted only healthy adults, and further research may be needed to validate the tele-assessment method in populations with cervical dysfunction or neck pain. These findings support the potential effectiveness of telerehabilitation services in assessing and managing musculoskeletal disorders.
