Optimizing the usability of automated teller machines for older adults

This research provides relevant information for the redesign of automated teller machines (ATMs) to better accommodate older adults, with hopes of aiding financial institutions in their trend toward a tellerless bank. Forty subjects, ranging from 18 to 65 years of age, interacted with three different ATM simulations. The level of detail was little, high and little with on screen help available. The font color was varied: red, green, or white with each participant. Font color and level of detail were investigated to determine preferences of younger and older adults. The preferred level of detail was found to vary by sex and age. A majority of the subjects, approximately 53%, favored the simulation with the optional help button which accommodated both first time and frequent ATM users. There were no significant interactions between age, sex, and color.
