Immersive Virtual Reality Case Study
Immersive Virtual Reality (IVE) has been implemented as an advanced experimental equipment in diverse research areas. In occupant behavior study, it has also gained reputations since its potentials serve realistic virtual experience to participants and allow researchers to record their responds. Nevertheless, it is still limited due to instrument and side effects lessening the tolerance of participants exposing to the experiment. As a result, conducting IVE experiment usually confronts by small sample size issue causing obstacles to data analysis such as overfitting, high bias and variance, false power of hypothesis test and so forth. To overcome these problems this problem, the authors utilized the potential of Hybrid Hidden Morkov Model (HMM) …show more content…
The outcome of synthetic data was evaluated and compared with IVE data. The results of cross validation, root mean square errors, and comparison of distribution showed that the hybrid model precisely estimated and generated the synthetic IVE data. (-- removed HTML --) >
INTRODUCTION
Immersive Virtual Reality (IVE) has been implemented in building occupant behavioral studies for many reasons. (-- removed HTML --) >. It allows users to practice and conduct experiments without real environments (in-situ), benefiting studies of occupant behaviors in non-existing or future buildings. It helps the designer to understand behavior of real occupants and optimize the building configurations so that the occupant preferences are properly served. Compared to experiments in in-situ, IVE

In IVE, the tolerance of participants is limited due to instruments and the side effects of IVE such as limited experimental space and time, realness, the inconvenience of using instruments, virtual reality sickness, and so forth. Due to those restrictions, it is expensive in both times and resources to have a large pool of data to accurately analyze outcomes. Furthermore, IVE experiments sometimes are confronted by the issue of small sample size [1], causing obstacles to data analysis processes such as the degree of overfitting[2] [3], high bias and variance [4], false power of hypothesis test, and many more [5] [6] [7] [8]. Moreover, IVE data may be used in higher critical applications rather than basic statistical analysis, e.g. building predictive models which require a large amount of samples to evaluate an accuracy with a low error rate [9]. Hence, the challenges of having sufficient samples are crucial for building occupant behavioral studies using IVE as experimental

    Virtually remembering the unearthly smell of burning garbage, diesel fuel, and the reside from the numerous rounds of ammunition fired comes to awaken the subconscious mind of former Infantry Officer of the Marine Corps named Tommy Furlong. In the meantime, the distinct whiff following the explosion of a Molotov cocktail suddenly takes Furlong back to a time where the past is lived once again. In reference to Christina Couch’s article titled, Healing Minds with Virtual Reality, explains how the immediate smell of the Molotov cocktail engulfed makes the former Infantry Officer relive certain experiences when he served abroad in Afghanistan in 2010. As Furlong sits comfortably in an office, Couch (2015) points that one of the sense of smell is one of the beginning stages of how the former Infantry Officer is mentally transported to a different time and place (para.…

    How to enhance generalizability of results of a single case design: The procedures for use with a single subject can be replicated with other subjects, greatly enhancing the generalizability of the results. Reports of research that employs single case experimental procedures do present the results from several subjects and often in several settings. The tradition in single case research has been to present the results from each subject individually rather than group data and to present overall means.…

With research designs and strategies, there come errors. These research designs include within-subject experiments, between-group experiments, correlation study, descriptive studies, and so many more.

    The study to be conducted in this project will be quasi experiment. This is because, quasi-experimental approaches may reduce the time and resources required because extensive pre-screening and randomization is not required or utilized. Quasi-experimental research may be more feasible because, it often does not have the time and logistical constraints associated with many true experimental designs. Also, it reduces the difficulty and ethical concerns that may surround the pre-selection and random assignment of test…

    In a laboratory experiment, there is a systematic variation of the independent variables while other irrelevant variables are kept constant. The basis of a laboratory experiment is the use of control. The researcher attempts to eliminate or control other variable that might intervene with the purity or accuracy of the experimental relationship between the IV and the DV. Due to the control of extraneous variation in a laboratory experiment, it becomes very helpful for the experimenter to draw conclusions about the influence of IV. By carrying out the investigation in the laboratory, it enables the experimenter to measure behavior with a greater accuracy and precision than would be possible in the natural environment. This method of research is…

    Certain terms in research connote philosophical approaches to obtaining and evaluating information. Through the scientific process, research studies begin by developing questions or hypotheses, then collecting data to help answer the questions or test the hypotheses. Research data are collected, analyzed, and interpreted to reach conclusions (Lodico, Spaulding, & Voegtle, 2010, p. 12). However, qualitative and quantitative studies have similarities and dissimilarities in the scientific process due to the different cognitive approaches in research designs. Qualitative studies utilize inductive reasoning while quantitative studies apply deductive logic (p. 10). Figure 1 illustrates the…
