  3. 2. Perceived Liveliness Impact on Sense of Safety : A Study on Women’s Perceived Safety in Human-Lacking Urban Environments through Virtual Reality

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ebba Rovig; [2023]
    Keywords : Perceived liveliness; women’s perceived safety; natural surveillance; street attributes; presence of others; virtual reality; urban environments; Upplevd livlighet; kvinnors uppfattade trygghet; naturlig övervakning; gatuattribut; närvaro av människor; virtuell verklighet; urbana miljöer;

    Abstract : Denna avhandling undersökte förhållandet mellan urbana attribut och upplevd livlighet och dess effekt på kvinnors upplevda säkerhet. Med utgångspunkt i teorier om naturlig övervakning [6] och vikten av att ha andra människor närvarande för att öka kvinnors säkerhet [17], utvärderades fysiska gatuattribut som förutspåddes öka miljöns livlighet.
