# MeTACAST: Target- and Context-aware Spatial Selection in VR
This is a repository for all data and analysis scripts used in the paper "[MeTACAST: Target- and Context-aware Spatial Selection in VR](https://doi.org/10.1109/TVCG.2023.3326517)", presented at [IEEE Visualization 2023](http://ieeevis.org/year/2023/welcome) and published in the journal [IEEE Transactions on Visualization and Computer Graphics](https://ieeexplore.ieee.org/xpl/RecentIssue.jsp?punumber=2945). If you use the results in new projects or use it in a different way we would appreciate a citation:

## Requirements

The R script contained within this repository requires, in addition to a [normal R installation](https://cran.r-project.org/), several packages including (potentially more):

* `boot`
* `PropCIs`
* `ggplot2`
* `reshape2`
* `glue`
* `dplyr`
* `ggpubr`

To install these required packages, run the following call from a command line: 
install.packages(c("boot", "PropCIs", "ggplot2", "reshape2", "glue", "dplyr","ggpubr"),repos="https://cran.rstudio.com")

## Running the R script

1. Clone this repository using 
git clone https://github.com/LixiangZhao98/MeTACAST-study.git
 or download the code as a ZIP file from the repository.

2. Change the Working Directory to `MeTACAST-study`. You can do this by
3. Run `confidenceIntervalMacros.R`, `analysis.R` and `Questionnaire.R` in sequence. You can do this by
To be noted that, `analysis.R` need to complete in one or two minutes since the large amount of the user data.
4. After the script completes, the figures (PDF format) will be generated in the folder `resultFiles/log` and `resultFiles/Questionnaire`. The new generated files will cover the files generated last time.

## Files produced

In the folder `resultFiles/log` and `resultFiles/Questionnaire` you should see the result PDFs. The following figures in [the paper](https://github.com/LixiangZhao98/asset/tree/master/Publications/Papers/MeTACAST.pdf) are corresponding to the PDFs.

Fig. 29-43 were generated by executing the `analysis.R` and `Questionnaire.R` for VR experts (using VR once a week) and novices (less than once a week) seperately.
Other images from the paper (i.e., Fig. 1-6, Fig.12–13) were created with the tool [Adobe Illustrator](https://www.adobe.com/products/illustrator/free-trial-download.html), so we could not script them.
