The Hive: University of Utah Research Data Repository. DOI: 10.7278/S50d-evm5-vh17. --------------------- DATA & FILE OVERVIEW --------------------- 1. File List A. Filename: "Participants" Short description: The data repository contains data from a study involving 10 participants. Each participant's data is stored in separate folders within the base directory, and these folders are named "date_subjectNumber" for easy identification. For instance, data for the first participant, collected on July 14, 2022, is stored in the folder "20220714_S01." These folders are consistently formatted, typically in CSV or Excel, and they contain variables specific to each participant's results. B. Filename: "Subject Numbers" Short description: Inside each participant folder, there is folder for each subject number. C. Filename: "Set Numbers" Short description: Within each subject number's folder, there are two subfolders named "Set1" and "Set2" to distinguish between the two sets of data. D. Filename: "Room Configuration" Short description: Within each 'Set Number' folder, there are eight subfolders. The naming of these subfolders is based on three key factors: room configuration (Headwall or Footwall), toilet position (Inside or Outside), and door type (Sliding or Swinging). To decode these folder names, we have employed a specific coding system: '1' signifies an inside toilet, while '2' denotes an outside toilet. For instance: * Footwall Slide Door folder - Corresponds to a Footwall room, Inside Toilet, with a Sliding door. * Footwall-2 Slide Door folder - Corresponds to a Footwall room, Outside Toilet, with a Sliding door. E. Filename: "IV Status" Short description: Within each room configuration level, there are two subfolders designated for IV status. One is intended for trials conducted with an IV pole, while the other is allocated for trials performed without an IV. F. Filename: "Exit Side of Bed" Short description: Within the "IV Status" level, you will find two additional subfolders that pertain to the exit side position. It's important to note that the terminology used in the paper may refer to these as the "Far (Right)" and "Close (Left)" sides of the bed. G. Filename: "Data" Short description: Within each "Exit Side of the Bed" subfolder, there are four dedicated subfolders, each serving as a repository for specific types of data. These subfolders are labeled as "Contact Data," "Door Data," "Object Position," and "Player Data." 2. Relationship between files: Described above. 3. Additional related data collected that was not included in the current data package: N/A 4. Are there multiple versions of the dataset? No -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: Data Collection: In this study, data was collected from ten healthy participants, including 5 males and 5 females. The data collection process was approved by the Institutional Review Board at the University of Utah. Various tracking sources, including a headset, two hand controllers, a lumbar spine tracker, and two foot trackers, were utilized to comprehensively analyze participants' movements within the virtual environment. Data was recorded at a rate of 2 Hz due to software limitations. VIVE trackers were positioned on the lumbar spine and dorsum of both feet. The data collection process involved participants completing 64 trials with randomized conditions related to room configuration, door types, starting side of the bed, and the presence of an IV pole. 2. Methods for processing the data: The data included in this repository is raw and has not undergone any processing. It represents the original data captured from the augmented reality (AR) environment. For all data, the origin was an arbitrary point in the corner of the room. The +x direction pointed from the foot of the bed towards the head of the bed. The +y direction pointed vertically. The +z direction pointed from the left side to the right side of the bed. Example: _______________ | ______ | | |__BED_| | | | ^ |_______ | |+z | Bath | | |-----> +x |__Room_|_______| 3. Instrument- or software-specific information needed to interpret the data: No special software is required as the data is provided in standard .csv and .xlsx formats 4. Standards and calibration information, if appropriate: N/A 5. Environmental/experimental conditions: During the study, each participant completed 64 trials that were randomized based on several factors: room configuration (4 configurations: headwall bathroom vs. footwall bathroom and inside wall toilet vs. outside wall toilet), door type (swing or sliding), starting side of the bed (close or far), and presence of an IV pole (IV or no IV). The 64 trials were divided into two sets (32 in each set) with one trial of each condition per set presented in a randomized order. 6. Describe any quality-assurance procedures performed on the data: N/A 7.

Fino, ----------------------------------------- DATA-SPECIFIC INFORMATION FOR: Contact Data ----------------------------------------- Within the Contact Data folder, you will discover .csv files containing data for both the right and left hands. This data is defined by the collision boxes within the augmented reality environment. When these collision boxes come into close proximity to various objects within the room, the exact timing of these contacts is recorded and stored within these files. 1. Number of variables: In each data file, we have recorded information related to four key variables. These variables serve to document and characterize contact events within the augmented reality environment. The four variables are: - Player Contact - Contact Object Name - Start Time - End Time 2. Number of cases/rows: The number of rows in these .csv files varies and depends on the quantity and duration of contact events. Each row in the file typically represents a specific contact event, so the more contacts that occur, the greater the number of rows in the .csv file. 3. Variable List A. Name: Player Contact Description: The "Player Contact" variable specifically identifies the area of the hand that came into contact with the objects present in the room. B. Name: Contact Object Name Description: The "Contact Object Name" variable is instrumental in indicating the specific objects that were involved during contact events. These objects could vary and include items such as a Toilet Grab Bar (with 'R' or 'L' designations for Right and Left), a Sink, or a Bed. C. Name: Start Time Description: The "Start Time" variable is crucial for capturing the exact moment when a contact event occurs. It records the time at which contact between the hand and an object in the augmented reality environment begins. It's important to note that whenever the contact is interrupted or ceases, a new start time is recorded to document the timing of each interaction. D. Name: End Time Description: The "End Time" variable serves to document the moment when a contact event is terminated. 4. Missing data codes: Code/symbol Definition Code/symbol Definition N/A 5.

This data encompasses information about the door's positional and rotational data, allowing us to track its dynamic behavior and interactions with other elements in the virtual world. 1. Number of variables: These variables encompass the "Object Name", "Time" data to track temporal events, and "Positional Data" (PosX, PosY, PosZ) and "Rotational Data" (RotX, RotY, RotZ) to detail the precise position and orientation of the doors in the virtual space. 2. Number of cases/rows: The number of rows in these .csv files varies and depends on the quantity and duration of the trial. 3.
