Visualization for Quality Healthcare: Patient Flow Exploration
ABB CRC.
2019 (English)Conference paper, Published paper (Refereed)
Abstract [en]

The health and medical institutes and hospitalsare facing several challenges in the short and long term, i.e.demographic changes, demands on improving quality, limitedresources and cost requirements. To cope with these challenges,the health care sector needs to become more efficient, whilemaintaining and improving the quality of care. Efficient andtransparent information flow across the whole system plays a keyrole even in this context. Being able to analyze the patient flowsas the first step will provide the possibility to more efficientlymanage medical resources and better serve incoming patients. Inthis work, we have developed a web-based portal for interactiveanalysis of patient flow data to assist hospital authorities toimprove and optimize the time and quality of the providedservices. The developed tool facilitates short and long termoptimization of resource allocation by analyzing the past, as wellas current, patient flows, identifying bottlenecks and exploringthe reasons for the occurred waiting times.

Abstract [en]

During the last decades, the industry has been undergoing extensive digitization leading to complex ensembles of humans, machines, autonomous agents, and sensors. With this new setup comes the challenge of how to appropriately support work-practices of industrial operators who now need to monitor and control complex industrial processes through remote interfaces. Information overflow and restrictive interfaces are two significant problems that operators face in their daily routines. In this PhD, I explore approaches to visualization and interaction that would reduce industrial operators' information load and enable them to perform their duties in an efficient, reliable, and safe manner. Industrial users and industrial settings are the starting points of my research.

In this thesis, I describe multiple examples of custom-tailored data visualizations that reduce the operator's visual load by consolidating large amounts of data into compact overview displays with often nontrivial data presentation. With respect to interaction, I propose several tangible and tactile interfaces, as well as concepts for natural interaction, that let the user freely interact with the control station and the information it depicts. Finally, I propose several concepts of adaptive systems that adjust to the operator's context to ensure their high situational awareness and convenience of interaction.

Even though this thesis is primarily intended for the community of interaction designers, I expect it to be of interest to a broader audience due to its relation to the user experience field. To a certain extent, everyone can resonate with the user's problems because, in our everyday life, we all are users of some technology and services. Furthermore, for a lay reader, this work can be seen as a comprehensive introduction to how the industry works and what role the human plays there.

Abstract [sv]

Under de senaste årtiondena har industrin digitaliserats i stor utsträckning och består nu av komplexa strukturer där människor, maskiner, autonoma agenter och sensorer samspelar. Människor arbetar ofta som operatörer i industrin, med uppgift att övervaka och styra maskinella processer på distans från kontrollrum. Den omfattande digitaliseringen medför nya utmaningar för operatörerna i och med att mängden tillgänglig information växer samtidigt som kontrollrummens användargränssnitt är otillräckliga för de ändrade förutsättningarna. I den här avhandlingen utforskar jag nya former av visualisering och interaktion som skulle kunna hjälpa operatörerna hantera de växande informationsmängderna och sköta sitt arbete på ett effektivt, tillförlitligt och säkert sätt.

Jag presenterar flera exempel på skräddarsydda datavisualiseringar som minskar belastningen på operatörerna genom att kombinera stora mängder data i kompakta, icke-triviala presentationsformer. När det gäller interaktion föreslår jag flera fysiska och taktila interaktionsformer som kan göra operatörernas arbete mera fritt och självstyrt. Jag presenterar slutligen koncept för adaptiva system som anpassar sig till operatörernas arbetssituation för att skapa smidig interaktion och stödja hög situationsmedvetenhet.

Avhandlingen vänder sig i första hand till interaktionsdesignområdet, men jag räknar med att den kan vara av intresse för en bredare publik i och med att den behandlar användarupplevelse. Vi använder alla tekniska produkter och tjänster i någon utsträckning och bör därför kunna relatera till industrioperatörernas utmaningar. Mitt arbete ger också en inblick i hur människans arbetssituation ser ut i dagens industri.
