Abstract
At finde vej i store, komplekse bygninger som hospitaler kan være svært. Mangelfuld vejvisning kan give både mental og fysisk belastning, forsinke besøgende og skabe ekstra arbejde for personalet med økonomiske omkostninger til følge. I tre mindre eksperimenter (n = 6, 15, 10) udviklede vi et RFID-aktiveret, multimodalt vejvisningssystem. Systemet bygger på procedurel (automatisk) generering af 2D- og 3D-rutevisualiseringer og tilpasset vejvisningsinformation. I et sammenlignende studie udført på stedet på Aalborg Universitetshospital Syd fandt vi, at en kombination af en egocentrisk 3D-rutevisning (set fra brugerens eget perspektiv) og et dynamisk allocentrisk kort (et oversigtskort set ovenfra), aktiveret via RFID-registrering, gav bedre resultater end det eksisterende system med skilte, farvede gulvlinjer m.m. Forbedringerne sås i gennemførelsestid, antal tøven og rutelængde. Selv om studierne havde begrænsede deltagerantal, peger resultaterne på et potentiale for en bredere implementering, der kan gavne både institutioner og brugere.
Finding your way in large, complex buildings like hospitals can be difficult. Inadequate wayfinding can cause both psychological and physiological strain, delay visitors, and create extra work for staff, with financial consequences for the institution. Across three small experiments (n = 6, 15, 10), we developed an RFID-enabled, multimodal wayfinding system. The system uses procedural (automatic) generation of 2D and 3D route visualizations and tailored wayfinding information. In a comparative in-situ study at Aalborg University Hospital South, we found that combining an egocentric 3D route view (from the user’s perspective) with a dynamic allocentric map (a bird’s-eye overview), activated by RFID detection, led to better wayfinding performance than the existing signage and colored floor lines. Improvements were observed in completion time, number of hesitations, and route length. Although the sample sizes were limited, the results indicate potential for a broader implementation that could benefit both institutions and wayfinders.
