QoE-and-Immersion-of-Dynamic-Point-Cloud

This repository contains the results of a subjective test on the quality of experience (QoE) for dynamic point clouds. Details and analysis can be found in the Reference section.

Data Description

The results include two files: rating_scores.csv and questionnaire_responses.csv. This section describes the content of each file.

Subjective Test Results

The table in file rating_scores.csv contains the following information of the subjective test results

| Column Name | Data Type | Description | |---------------|-----------|--------------------------------------------------------------| | participant | Int | The index of the participant | | object | String | The name of the 3D object in the test sequence | | startquality | String | The quality in the first 5 s of the test sequence | | endquality | String | The quality in the last 5 s of the test sequence | | distance | Float | The viewing distance (m) | | startgqp | Int | The Geometry QP (G-QP) in the first 5 s of the test sequence | | starttqp | Int | The Texture QP (T-QP) in the first 5 s of the test sequence | | endgqp | Int | The Geometry QP (G-QP) in the last 5 s of the test sequence | | endtqp | Int | The Texture QP (G-QP) in the last 5 s of the test sequence | | qoe | Int | The score rated by the participant |

Questionnaire Responses

Before the test, we asked the participant to provide some background information, tested their color vision with Ishihara^1.

After the test, the participants answered a survey about cybersickness and the immersion level of the tested objects. The answers are stored in the table of file questionnaire_responses.csv. The structure of the table is described as follow.

| Column Name | Data Type | Description | |---------------------------------------------------------------------------------------------------------------|-----------|------------------------------------------------------------------------------------------------------------------| | participant | Int | The index of the participant | | Which number do you see below? | Int | The first tested number for Ishihara test (must be 12) | | Which number do you see below? | Int | The second tested number for Ishihara test (must be 45) | | Which number do you see below? | Int | The third tested number for Ishihara test (must be 74) | | During the assignment I felt... [General discomfort] | String | Level of agreement with options: Strongly disagree, Disagree, Neutral, Agree, Strongly Agree | | During the assignment I felt... [Nausea] | String | Level of agreement with options: Strongly disagree, Disagree, Neutral, Agree, Strongly Agree | | During the assignment I felt... [Sweating] | String | Level of agreement with options: Strongly disagree, Disagree, Neutral, Agree, Strongly Agree | | During the assignment I felt... [Headache] | String | Level of agreement with options: Strongly disagree, Disagree, Neutral, Agree, Strongly Agree | | During the assignment I felt... [Dizziness] | String | Level of agreement with options: Strongly disagree, Disagree, Neutral, Agree, Strongly Agree | | How would you describe the general experience? [I felt the objects were part of the real environment] | String | Level of agreement with options: Strongly disagree, Disagree, Neutral, Agree, Strongly Agree | | What is your gender? | String | Gender with options: Male, Female, Non-binary, Prefer not to say | | What is your age group? | String | Age group with options: Under 18, 18-24, 25-34, 35-44, 45-54, 55-64, 65-74, 75-84, 85 or older | | How often have you watched/experienced extended reality content (e.g, 360 videos/games, holographic content)? | String | Frequency with options: Never, Once, A few times, Monthly, Weekly, Daily |
