Next Generation User Interface for Digital Microscopy in Hematology
Abstract: This project was performed in collaboration with CellaVision, a company that provides digital solutions for medical microscopy in hematology. Together with a hardware for blood analysis, CellaVision provides a software where cell images are displayed for further analysis. The user interface of this software was the focus of this research. With the aim to provide a suggestion of improvement for the user interface, the project followed a user-centered design process. Information was gathered by performing a heuristic evaluation on the system, conducting expert interviews and doing contextual inquiries with end users. After generating an overall concept, a low fidelity prototype was created and tested with end users. A more detailed, high fidelity prototype, was then created and further tested. A final concept was developed as a suggestion of improvement. After performing quantitative tests with the high fidelity prototype, the result displayed an improvement of the usability of the user interface, showing a System Usability Scale value of 84.1 for the new user interface versus a value of 33.3 for the old user interface. From the result it was concluded that user centered design can result in a product with higher usability compared to a product developed without the user in focus. A user-centered design process contributes to a result with a solid base, matching the user goals and requirements. This project will hopefully motivate future design processes to work in close collaboration with the end users.
