Abstract
Robotassisterede operationer er en relativt ny måde at operere på i Urologisk Afdeling på Aalborg Hospital. De giver bedre kvalitet, men tager længere tid end traditionelle operationer. Afdelingen ønsker derfor at gøre operationerne hurtigere. For at støtte dette udviklede vi prototyper, der kan indsamle data fra operationer til analyser af tidsforbrug, operationskvalitet og til brug i undervisning. Vi udviklede prototyperne via en innovativ softwareudviklingsproces baseret på Essence-rammeværket, som bruges til at strukturere og styre arbejdet. Gennem casen undersøgte vi, hvordan prototyping (tidlige, forenklede versioner af et system) støtter Essence ved at hjælpe os som designere med løbende at lære, opdage, skabe og forbedre design. Vi introducerer begreberne Surrogate Challenger og Surrogate Users som stedfortrædende roller, der kan bruges, når kunden ikke kan stille med en kunde på stedet eller testpersoner. Surrogate Challenger fungerer som en kunderepræsentant på stedet og deltager i daglige drøftelser og evalueringer, når den egentlige kunde ikke er tilgængelig. Surrogate Users fungerer som testpersoner, der kan deltage i hyppige og enkle tests af prototyper. For at mindske videnskløften mellem Surrogate Users og de egentlige brugere introducerer vi idéen om at mappe problemer fra ét domæne til et andet. Vi viser, hvordan et problem, kirurgen møder under operationen, kan omsættes til en opgave, som de stedfortrædende brugere kan løse i tests. Specialet beskriver vores proces, vores undersøgelser samt de idéer og prototyper, der blev udviklet og demonstreret for Urologisk Afdeling.
Robotically assisted surgery is a relatively new practice at the Department of Urology at Aalborg Hospital. These procedures offer better quality but take longer than traditional surgery, so the department wants to shorten them. To support this goal, we developed prototypes that collect data during surgeries for analyses of time use, surgical quality, and educational purposes. We built these prototypes using an innovative software development process based on the Essence framework, which helps structure and guide work practices. Through this case, we studied how prototyping—early, simplified versions of a system—supports Essence by helping designers learn, discover, generate, and refine designs step by step. We introduce the concepts of Surrogate Challenger and Surrogate Users as proxy roles for situations where the customer cannot provide an on-site customer or test subjects. The Surrogate Challenger acts as an on-site customer who can take part in daily discussions and evaluations when the real on-site customer is unavailable. Surrogate Users act as test subjects who can participate in frequent, simple tests of prototypes. To narrow the knowledge gap between Surrogate Users and real users, we propose mapping problems from one domain to another. We show how a problem a surgeon faces during surgery can be translated into a task that surrogate users can perform in tests. This thesis describes our process, research, and the ideas and prototypes developed and demonstrated to the Department of Urology.
