ESR 10: Traceable and comparable evaluation methodology for biometric systems usability

This project aimed to develop a new methodology for biometric systems evaluation, designing different user interaction assessments.

What has been achieved and the impacts

These interaction factors were included in a novel methodology that aims to assess the extent to which users’ capabilities, experience, and age influence the interaction with the biometrics systems. This means evaluating the accessibility of biometric recognition systems. Depending on the characteristics of the customers, the outcome of the recognition process could be affected.

The novel methodology is validated through two different scenario evaluations. For each evaluation, a specific biometric system and design scenario of use were developed. Heterogeneous populations of users, composed by different user groups (e.g., younger adults, older adults, people with accessibility concerns), were recruited for the two interaction assessments. 

The results obtained throughout the experiments outlined how the users’ capabilities, experience, and age affect the biometric systems’ performance. In this way, it is possible to define solutions to eradicate such influence.
Thus, the main impact will be contributing to the definition of new guidelines to develop more usable and accessible biometric systems.
