ArtículoA User-Centered Framework for the Design of Usable ATM Interfaces(A User-Centered Framework for the Design of Usable ATM Interfaces, 2019-07) Aguirre, Joel ; Moquillaza, Arturo ; Paz, FreddyNowadays, the design of usable interfaces is a challenge for every software developer. Little or no consideration of the user-centered design guidelines make systems difficult to use, and the embedded systems in the Automated Teller Machines (ATM) are not an exception to this problem. In order to improve and ensure the usability of the user interfaces of software in this domain, several user-centered design methods and techniques were analyzed and applied to formulate a framework for guiding a design process. The paper provides an analysis of a variety of methods used in the self-service technologies domain and by formal design methodologies; for instance, the standard ISO 13047. In addition, the article describes the process followed to select the most appropriate user-centered design methods that fit the specific ATM domain. This analysis includes surveys and expert judgment, conducted with ATM and usability experts, which show a correct selection of the methods.
ArtículoDeveloping QR Authentication and Fingerprint Record in an ATM Interface Using User-Centered Design Techniques(Springer Verlag, 2019-07) Chumpitaz, Diana ; Pereda, Kevin ; Espinoza, Katherine ; Villarreal, Carlos ; Perez, William ; Moquillaza, Arturo ; Díaz, Jaime ; Paz, FreddyATMs are widely used around the world, which leads to the development of new functionalities that need to consider usability. For this reason, the following article presents the development of graphical interfaces for ATM of BBVA Continental Bank, which follows a user-centered process design. In the first place, we gathered information about our target user. Then, we developed a prototype based on the previous information and the needs of the bank, which also took into account expert’s feedback. Finally, real users in the bank itself validated the prototypes.
ArtículoDevelopment and Validation of Usability Heuristics for Evaluation of Interfaces in ATMs(Springer Verlag, 2019-07) Chanco, Cristhian ; Moquillaza, Arturo ; Paz, FreddyATM systems are part of the devices that have more managed approach and facilitate the use of financial services for people. However, on occasions, displayed interfaces can be frustrating to use. Usability is a principle that contemplates such situations, so it is necessary to have appropriate tools to evaluate ease of use on the products. For this reason, we present a revised version of eighteen usability heuristics proposed for ATM applications. In this paper, we describe the process that is followed from the collection of information, creation of the heuristic set, validation and refinement.
