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