Research has also suggested that there is a relationship between learner preference and creativity. This study uses the VARK learning styles inventory to assess students learning style then explores how this learning preference affect the use of Augmented Reality (AR) and Virtual Reality (VR) in the creative design process.

The primary objective is to use this application and integrate it in to a virtual critique platform to be used in Architectural and Interior Design critiques/reviews.

Digital media tools have become for design studios and educational facilities a setting for idea representation, development and communication within the design process. The evolution of digital media tools has shifted from two-dimensional applications to more diverse and flexible threedimensional scenarios. The inclusion of parameters as modelling attributes give designers new possibilities by which they can enhance their creativity and idea generation processes. The purpose of this study was to identify unexpected discoveries as milestones for creativity within two digital media tools; Geometric Modelling Environments (GME) and Parametric Design Environments (PDE). A protocol analysis study was conducted between the two digital environments to comprehend the design process. The level of creativeness of each design outcome was contrasted with the digital environment used.

Design/methodology/approach A questionnaire on emergency preparedness was provided to 30 randomly recruited participants from the industry. The survey consisted of 30 open and closed-ended questions, focusing on basic demographic information, information about emergency preparedness of the facility, food safety and issues regarding power management. Findings The findings of this study provide insight on the emergency preparedness of the hospitality industry in Sri Lanka. Research limitations/implications In its current iteration, the sample size was a major limitation. The study was conducted by using an online questionnaire, and that affected the number of responses received. Social implications The results provide insight into how improvements can be made in future developments of similar nature es...

In this research project, two different types of Head-Mounted Display (HMD) systems were used. One type of HMD provided six degrees of freedom and the other HMD provided three degrees of freedom. The research findings provide comparison on the functionality of the different types of HMDs and the sense of presence in VR environments. Sense of presence is defined as the sense of “being there” in a computer-simulated environment. The outcomes of this research are (a) development of a new presence questionnaire that focuses on newer VR systems and (b) understanding student perception of using VR in design projects.

The article focuses on how technology traits affect the creative design process. 10 subjects were selected and their design process was analyzed using protocol analysis. The results of the study indicate that epistemic action reduces cognitive load, thereby reducing fixation in the design process and enhancing the creative design process.

OBJECTIVE: Memory loss and physical impairments have been identified as factors that restrict older adults from living independently. The objectives were (1) to develop a hybrid space within the participants' living environments using an Augmented Reality object location and information system based on visual and spatial organization and (2) to assess the users' perceptions of using such technology. METHOD: Three older adults who had a physical impairment and also suffered mild memory loss participated in the study. These three individuals were provided with the mobile system, and their subjective responses were documented through interviews and a questionnaire. RESULTS: The results of the study suggest that participants found the system very useful and easy to use. CONCLUSIONS: The results of the study suggest that the older adults who took part in the study were very open to the idea of using such an AR object location and information system based on visual and spatial organization hosted on electronic mobile devices to enhance their living environments.

By using prototypes, design students can better visualize structures and can give students a more concrete result when working on a design project. According to a study by Grosslight, Unger, Jay and Smith (1991), students are likely to think of prototypes as physical copies of reality that envelop various spatiotemporal views, instead of representations that envelop various theoretical perspectives. Past literature and research has suggests that student’s rate building prototypes highly when compared with other types of representations, which implies that they are better able to learn the design process when using prototypes (Lemons, Carberry, Swan & Rogers, 2010). This study documents alternate modeling strategies utilising technologies such as Virtual Reality (VR) and Augmented Reality (AR) in Architectural and Interior Design education through the Techn...

In the study, two experienced designers were selected and were provided with a design task. While one designer was subjected to subliminal suggestions through a slide show presentation and a video clip, the other designer was not. The design sessions of both designers were recorded, coded and analyzed, using concurrent and retrospective protocol methods. Comparison of the two design protocols provided convincing evidence of the occurrence of SMI influenced by subliminal suggestions. 2012 Elsevier Ltd. All rights reserved.

In order to travel from one point to another, a person employs different types of knowledge, defined as spatial knowledge, which facilitates the ability of wayfinding. The ability to acquire spatial knowledge can be enhanced by increasing the imageabiliy of the environment. This environmental characteristic could be linked to an important human behavior, the sense of belonging, the feeling of belonging to a group or a place. Previous literature has reported the significance of sense of belonging for psychological, social, and physical well being. A higher level of sense of belonging to a place can yield valuable results especially to an academic environment such as achieving better academic standing, closer relationships with peers, and elevated self confidence. Since sense of belonging deals greatly with the surrounding environment, it is necessary for educ...

The main objective of the paper is to provide a solution for dysfunctional public spaces by rejuvenating them with the use of Augmented Reality Systems (ARS). The study explores how digital interventions in urban public spaces can be used without impairment to the historic relevance, social integrity or urban fabric of a location.

The specific research question was “How do VR visualizations compare with 2D photos in terms of (1) affective responses, (2) attitudinal/behavioral responses, and (3) cognitive load—that is, task efforts and experiences associated with technology?” A quasi-experimental study was conducted over two time periods with independent sample pools. A boutique hotel lobby and a guest room were captured in 2D and VR formats. Subjects were randomly assigned to one of the two types of visualizations. The sample comprised 84 university undergraduate students from the South-Central United States. Nonparametric tests were used to test the proposed hypotheses. There was a statistically significant difference between two visual conditions for several variables—that is, pleasure, satisfaction, ...
