Everyday environments as cues to smoke: Personalized environments in virtual reality to elicit smoking cravings - Data and Analysis Code

Herein is the dataset collected during our VR experiment and the data analysis code used, as part of my MSc thesis project, titled "Everyday environments as cues to smoke: Personalized environments in virtual reality to elicit smoking cravings."<br>Our experiment involved presenting personalized and non-personalized virtual reality environments to participants and asking them how familiar was the experience at the end of each timed environment presentation. After all environments had been presented, participants were asked to fill-in questionnaires regarding the sense of presence elicited by our system, as well as give scores for the usability of the user interface they were asked to interact with.<br>We performed data analysis to determine:1. Whether personalized virtual environments elicited higher experience familiarity than non-personalized ones.2. Whether sense of presence positively affected elicited experience familiarity. 3. How our system scored on the sense of presence elicited and how it compared to norm values reported by the questionnaire providers.4. How our system scored on a component-based usability questionnaire and whether it scored higher than a norm value reported by the questionnaire providers.5. How our system scored on additional usability questions we formulated.<br>More information can be found in the README file contained.

本数据集为我们的虚拟现实（Virtual Reality，VR）实验过程中采集的数据及所用的数据分析代码，属于本人硕士学位论文项目的一部分，论文题目为《作为吸烟线索的日常环境：用于诱发吸烟渴求的虚拟现实个性化环境》。
本实验向被试呈现个性化与非个性化虚拟现实环境，并在每次定时环境呈现结束后询问被试对该体验的熟悉程度。待所有环境呈现完毕后，要求被试填写关于本系统所诱发临场感（sense of presence）的问卷，并对其需交互的用户界面的易用性进行评分。
本研究开展数据分析以探究以下内容：
1. 个性化虚拟现实环境是否比非个性化环境能诱发更高的体验熟悉度；
2. 临场感是否对诱发的体验熟悉度产生正向影响；
3. 本系统在临场感维度的评分情况，以及其与问卷供应商公布的常模数值的对比结果；
4. 本系统在基于组件的易用性问卷（component-based usability questionnaire）上的得分，以及该得分是否高于问卷供应商公布的常模数值；
5. 本系统在我们自行设计的附加易用性问题上的得分情况。
