Text Input in Virtual Reality: A Preliminary Evaluation of the Drum-Like VR Keyboard
Boletsis, Costas; Kongsvik, Stian (Journal article; Peer reviewed, 2019)The drum-like virtual reality (VR) keyboard is a contemporary, controller-based interface for text input in VR that uses a drum set metaphor. The controllers are used as sticks which, through downward movements, “press” ... -
The New Era of Virtual Reality Locomotion: A Systematic Literature Review of Techniques and a Proposed Typology
Boletsis, Costas (Journal article, 2017)The latest technical and interaction advancements that took place in the Virtual Reality (VR) field have marked a new era, not only for VR, but also for VR locomotion. Although the latest advancements in VR locomotion have ... -
The Smartkuber Case Study: Lessons Learned from the Development of an Augmented Reality Serious Game for Cognitive Screening
Boletsis, Costas; McCallum, Simon (Chapter, 2017)In this work, we present a case study, examining the design, development, and evaluation of an Augmented Reality serious game for cognitive screening (namely Smartkuber), which aims to provide reliable and motivating ... -
A Typology of Virtual Reality Locomotion Techniques
Boletsis, Costas; Chasanidou, Dimitra (Peer reviewed; Journal article, 2022)Researchers have proposed a wide range of categorization schemes in order to characterize the space of VR locomotion techniques. In a previous work, a typology of VR locomotion techniques was proposed, introducing motion-based, ... -
A User Experience Questionnaire for VR Locomotion: Formulation and Preliminary Evaluation
Boletsis, Costas (Peer reviewed; Journal article, 2020)When evaluating virtual reality (VR) locomotion techniques, the user experience metrics that are used are usually either focused on specific experiential dimensions or based on non-standardised, subjective reporting. The ... -
Virtual Bodystorming: Utilizing Virtual Reality for Prototyping in Service Design
Boletsis, Costas; Karahasanovic, Amela; Fjuk, Annita (Chapter, 2017)The paper describes our ongoing work on a new prototyping method for service design, Virtual Bodystorming. Virtual Bodystorming utilizes Virtual Reality (VR) and enables the user to role-play the service scenario in a fully ... -
Virtual Reality for Prototyping Service Journeys
Boletsis, Costas (Journal article; Peer reviewed, 2018)The use of virtual elements for developing new service prototyping environments and more realistic simulations has been suggested as a way to optimise the service prototyping process. This work examines the application of ... -
VR Locomotion in the New Era of Virtual Reality: An Empirical Comparison of Prevalent Techniques
Boletsis, Costas; Cedergren, Jarl Erik (Journal article; Peer reviewed, 2019)The latest technical and interaction advancements within the virtual reality (VR) field have marked a new era, not only for VR, but also for VR locomotion. In this era, well-established, prevalent VR locomotion techniques ... -
VR service walkthrough: A virtual reality-based method for service prototyping
Boletsis, Costas (Chapter, 2018)This work introduces a new service prototyping method called the VR (virtual reality) service walkthrough. The VR service walkthrough is a virtual simulation of a service journey, representing how the service unfolds over ...
