  1. 1. Investigation on Enhancing Fire Threat Perception in Virtual Reality through Subject-Expectancy Effect

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Hsuan-Ting Liu; [2023]
    Nyckelord :Virtual reality; safe distance; subject-expectancy effect; thermal radiation; placebo effect; fire scenario.; Technology and Engineering;

    Sammanfattning : This thesis examines the use of subject-expectancy effect on enhancing fire threat perception in virtual reality. The study involves a virtual fire scenario design and 33 participants who experience virtual fires of three different scales in the scenario using a head-mounted display as visual and auditory perception and adopting physical movement in real world as their way of locomotion.

  3. 2. Asymmetrical Collaboration in VR and the Impact of Embodiment during a Guided Procedural Learning Task

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Larissa Wagnerberger; [2023]
    Nyckelord :virtual reality; symmetrical and asymmetrical system; collaborative learning; procedural learning; embodiment; virtual reality; symmetriska och asymmetriska system; samarbetsinriktad inlärning; procedurellt lärande; förkroppsligande;

    Sammanfattning : Virtual Reality (VR) is valuable for educational purposes, particularly procedural learning. However, single-user applications lack the benefits of teacher guidance. Symmetrical VR systems, where both teacher and student use VR, have limitations in supervision and accessing external materials. LÄS MER

  4. 3. Local collaboration in a Mixed Reality environment : Adding virtual heads to improve social presence

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Lucas Detto; [2023]
    Nyckelord :Mixed reality; Augmented reality; Social presence; Avatars; Uncanny valley; Video see-through; Blandad verklighet; Förstärkt verklighet; Social närvaro; Avatarer; Kusliga dalen; Video genomskinlig;

    Sammanfattning : This thesis investigates the use of virtual avatar heads to enhance local video see-through collaboration in a mixed reality environment. When users engage with each other using a head-mounted display, the device sits atop their head and obstructs their view, concealing their gaze and facial expressions while collaborating. LÄS MER

  5. 4. Integration of eye tracking device and 3D motion capture for simultaneous gaze and body movement analysis

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Deepa Narasappa; [2022]
    Nyckelord :Eye tracker; Motion capture system; Vicon; coordinate transformation; gaze; upper limb movement.;

    Sammanfattning : The purpose of this project was to analyze the coordination between gaze and the upper limb movement while performing a predefined task. We implemented a method to simultaneously compute and visualize recorded gaze data from a head mounted eye tracker and motion data from a motion capture system in the same coordinate system. LÄS MER

  7. 5. AR Shopping List : Exploring the Design Space of Smart Glasses to Allow Real-time Recording with Multiple Input Formats

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yuxuan Huang; [2022]
    Nyckelord :Shopping list; smart glasses; optical head-mounted displays; augmented reality; memory expansion.;

    Sammanfattning : It is widely considered that in-store shopping is a repetitive yet vital activity in human life. People are accustomed to making shopping lists on a piece of paper or on their mobile phones, or more commonly, memorizing the list in their minds. LÄS MER
