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
start_quality String The quality in the first 5 s of the test sequence
end_quality String The quality in the last 5 s of the test sequence
distance Float The viewing distance (m)
start_gqp Int The Geometry QP (G-QP) in the first 5 s of the test sequence
start_tqp Int The Texture QP (T-QP) in the first 5 s of the test sequence
end_gqp Int The Geometry QP (G-QP) in the last 5 s of the test sequence
end_tqp 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 Ishihara1.

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

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
