Engaging Pictorial Images and Voice Prompts Interface Design Strategy to Create Easy to use banking ATM System Interfaces in Nigeria

Felix C. Aguboshim, Gail S. Miles


The existing banking ATMs in Nigeria do not adequately cater for a variety of people with varying abilities and literacy levels despite the significant importance of ATM technological innovations in Nigeria, especially in the banking sectors. Illiterate and semiliterate Nigerians, representing about 40.33%, do not perceive the ATMs as useful or easy-to-use. The purpose of this case study was to identify strategies used by software developers of banking ATM systems in Nigeria to create easy-to-use banking ATM system interfaces in Nigeria. The technology acceptance model was adopted as the conceptual framework. One organization in Enugu, Nigeria was used for this study’s population. Data were collected through semi-structured, in-depth face-to-face interviews with nine banking ATM system interface developers and the analysis of 11 documents. Findings from the participants were validated through member checking. One major theme that emerged from data analysis was value of pictorial images and voice prompts in interface design, that encompass the use of: (a) pictorial images, and enhanced voice prompts with short transaction cycle, (b) voice feedback in users’ own language, (c) text-free user interface and extensive use of hand-drawn, and (d) graphics /imagery and voice as inputs. Strategies illustrated by the findings from this study may serve as a basis for positive economic development and social change in this area and may advance the use of other technology outlets that require easy-to-use system interfaces.

Keywords: Banking ATM, pictorial images, Voice prompt, interface design, easy-to-use, ease of use, literacy levels.
