Redesigning a Handheld Scanner for Veterinary Care, Improving Usability and Contamination Control Through Human-Centered Design

Abstract

As a response to an increase in antimicrobial resistance within veterinary care, Odin well aims to introduce their bacteria measurement technology as a more effective solution for diagnosing and treatment selection. This thesis explores the redesign of the Odinwell handheld scanner as well as the development of an exchangeable tip solution, for use within veterinary care. With a human-centered design approach, the project features theoretical studies, benchmarking, interviews, observations, and user testing to understand the specific needs within veterinary care. Based on the findings, the scanner body was redesigned to create a more intuitive and usable product. The redesign features a new grip shape for improved ergonomics as well as a new overall body shape for improved usability. Additionally, a digital interface design combined with a larger screen and redesigned button layout was created, allowing increased functionality and better user interaction. Finally, a single use tip solution was developed, providing the veterinarian with an effective way of preventing cross contamination between patients
