Careful considerations in designing and organizing information for restaurant point-of-sale (POS) systems can affect user experience. Unfortunately, usability guidelines are sparse for these systems. Applications from other studies, such as categorical organization and F-shape, are implemented in an experimental interface as a starting point of discussion. A control interface was designed after the default version of NCR Aloha’s POS program: Aloha Table Service. Novice and expert order taking strategies were also observed to compare input differences. This study examined selection time, total time, and selection accuracy across both order and interface types. The results show that time and number of key presses are significantly reduced under the treatment interface, and that teaching expert order taking strategies to novice users may help reduce cognitive load.

In this episode EALA is joined by Kathy Hoffman, the Executive Director of Innovation & Special Education Initiatives at Arizona State University, and Co Leader behind Project OASIS. Listen in as we discuss how Project Oasis is ensuring all learners, particularly students with learning differences, have access to the opportunities they need to have lifelong success.
