HOURS SUMMARY
Total: 143 hours
HOURS journal
1/29/23 - 4 Hours
Set up student journal, joined course slack, reviewed and explored the wiki as well as course homepage
9 Changes to Wiki
10-minute changes:
Add recent VR hardware devices to the list of VR hardware on the wiki homepage
On the VR development software page, there are #todo items that have not been executed.
Since there is a dedicated page for VR development software in depth, the “VR development software” page under home> "I want to decide which VR tools to use for a specific user" can have a proper page title to avoid confusion regarding page hierarchy. [Completed] Changed the page title
1 hour to complete
Under I want to decide which VR tools to use for a specific use case, Unreal Engine 4 is empty.
Currently, if you access the VR Development Software comparison page, users only get access to the parts within the page about each software. It would be a better user workflow to also have links to each software page.
On WebVR: Overview page, Wiki displays links to WebVR software. Some links lead to the software homepages while some lead to our wiki's review/analysis page. We can add links to Wiki pages as well as company websites to fix such inconsistencies in the links on the page.
10 hours to complete
There is a page for Low budget VR headsets. However, it would be great to have a page dedicated to comparing low to high-budget VR headsets. It would be ideal to have each headset include a link back to pages already existing about each headset. This would take a while since doing comparisons of currently available headsets can take more than a couple of hours
It would be great to have a page on Meta’s Quest Pro under VR hardware. As the functionality of the quest pro increases, users can perform a variety of tasks. Adding critical research and potential usage of them on the wiki.
Under the applications of the VR page, VR in Design/Art can be added. Immersive contemporary art grows more as VR and AR technologies become readily available to the public. It would be a great addition to the list of applications on our wiki.
Read an article on Meta Quest Pro's mixed reality system

3~5 Project Idea
Utilizing Covid Travel Data From the Wiki, the project evaluates software and UX comparison of VR-Viz and other data visualization software.
3 things I'll do during the project
besides Given Covid Dataset, work with the Covid case number trend and number
Visualize given covid travel data in VR with a map
Make the viewing and analyzing experience collaborative (2+ users)
Class Activity
Generate 2D or web data plots as well as VR demo(sample data) to compare and evaluate the difference.
What defines a good type of dataset for VR/immersive data visualization?
Potential Deliverables
Add the international Covid Travel dataset to the dataset section
Find similar dataset working with other
Comparing and Evaluating Collaborative 3D architecture modeling(structure, interior) visualization software. (visi draft, unreal engine, arki, and potentially gravity sketch as well)
3 things I'll do during the project
Use and evaluate at least 2 software and review how well each can represent spacial elements
Review and read VR user experience research to evaluate egocentric data/workflow as well as the collaborative aspect
Review how these software(supporting more refined visualizations as well as UI experience) could potentially be used to better provide collaborative data visualization space for scientific research purposes
Class Activity
Students get paired up in a group of two. After seeing a provided sample shape, each group try to make the same/similar shape using different software options.
Potential Deliverables
Software Analysis and comparisons for VR architecture under VR for architecture section
Generating a 3D visualization of Twitter community detection results depending on selected communities. (Not sure about datasets. )
3 things I'll do during the project
Get or make a community detection algorithm-produced dataset (had a link to a public project but the dataset link seems to be invalid)
Generate a 3D version of the result(if possible, for different versions depending on different topics in interest)
Make the dataset viewing and analyzing experience collaborative with Photon engine (research needed for details)
Class Activity
Using a simple collaborative workspace, grouping and creative Twitter communities collaboratively (this can be as simple as 30 snapshots potentially evaluating which visualization software suits the best)
Potential Deliverables
Addition to Twitter API/ dataset section of the WIKI. as well as a page on Twitter community detection algorithms
(Potential project idea: VR version of NASA's Eyes on earth project) using one of
Software Evaluation Metrics
How intuitive is it to learn and use?
How easy it is to collaborate with another user (editing the same virtual object, communication, space)
How easy it is to learn the software's advanced features online?
It is compatible with several operating systems and devices?
How was the quality of the rendering of the space(frames per sec, color saturation, user feedback, etc.)
2/8/23 - 3.5 hrs
Finished DinoVR activities and survey
Tried DinoVR with different features enabled
Watched a course video on Community detection
Girvan-Newman Algorithm, edge betweenness values, high edge betweenness means high possibility of holding edges together.
how does information flow through the network? Social network. How do people find out about new jobs? : Mark Grannovetter's work in 1960s.
Contacts were often acquaintances rather than closer friends
Two perspectives on friendships: 1. structural -- spanning different parts of the network 2. Interpersonal -- can be strong or weak
Strength and structure of the friendships. Information flow: long-range edges allow you to gather information from different parts of the network and get a job. -> access from different communities
Social network evolve to naturally form communities -> triadic closure. = high clustering coefficient
Empirical study by Bearman and Moody: Teenage girls with low clustering coefficient are more likely to contemplate suicide
proves the natural tendency and dependency of a person to be deeply embedded in the network/clusters
However, Granovetter's theory was not tested. -> 2007 this was evaluated based on 20% of EU population
2/11/23 - 4hrs
read articles on Community detection algorithms and networks
Watched tutorials on Gephi and Force Atlas 3d for 3d visualization of the network
Force Directed Graph
Gephi's clustering algorithms for Modularity seem to be the most widely used algorithm for the community detection for social media accounts and similar datasets
Found a step-by-step tutorial on Sample datasets(2)
Have not found a way to get the resulting file from Gephi to Unity Yet.
Phonton seems to be the most reliable collaboration tool.
2/12/23 - 3.5hrs
Was stuck finding ways to make Gephi graphs into 3D and turn that into VR experience in Unity
Jakobi redirected me to check out the force-directed approach which is another way of displaying closeness among nodes
Unity has a physics engine as well as tools to develop force-directed graph representation in 3D
Downloaded unity hub
Found some other Github repo for 3D force-directed graphs
Changed from Twitter social network community detection to general community detection
Twitter just shut down its public API (now for full access, we need to pay?)
Other datasets were also available
Focusing on compare/contrast between Gephi's 2D community detection software vs. Unity Force-directed graph in VR
In-class activity: compare community visualization produced by Gephi(2D) vs. force-directed graph of the network(VR)
Which method visualized the separation of communities(or clusters) better and why do you think that method did a better job visualizing the individual group of nodes?
What are the differences between the two methods?
Which method allowed better visualization and understanding of the links between groups or nodes? What aspect of the method do you think enabled such visualization?
Wiki Contributions/deliverables: Tutorials on Gephi and Force Directed Graphs
How to use Gephi and upload data(node and edge files) to develop a community detection network.
Introduction to Modularity and 4 main algorithms in Gephi
This page will go under the Related Technologies Section of the wiki
Tutorial and background summary: what is a force-directed graph and how to make one using Unity.
Collaborative Functionalities:
Users(2) can touch each node and apply force to the graph
Users(2) can be in a synchronized 3D virtual space in which they can interact with, discuss, and analyze patterns of rendered community networks.
Worked on 3 min presentation

3/1/2023 - 1 hrs
finished Melvin's in-class activity
class in class activities prep
had some issues with sidequest working with my personal computer.
3/3/2023 - 4hrs
Debugging the graph problem. At the moment, the graph get's generated. However, it disappears into the void.
Tried to work with the collider as well as mass and gravity setting for the node prefab.
3/5/2023 -9 hrs
Found the bug. It was happening due to the fact that the generated graph when I start the application (from the script) collides with the plane in the scene, causing the nodes and the graph to "bounce" off and disappear at high speed.
worked with gravity and graph script setting.
Larger dataset was getting buggy. For the in-class activity on 3/7, decided to work with dataset from Les Misérables.
Generated Gephi comparison graph on the same dataset
Generated 3d VR force directed graph
worked on the in-class handout
Generated step by step tutorials for generating a bigger net work community/cluster graphs using gephi
3/6/2023 - 2hrs
worked on the in-class activities handout.
Tried out HackMD for the first time (originally tried to make a handout with a google doc. However, I saw hackMD handout and decided to learn how to use it and make one for my in-class activity).
My in-class activity handout can be found here.
The dataset and the apk file I used for the in-class activity can be found here.
3/8/2023 -2.5 hrs
tried generating a larger graph with new setting and it seems like the graph is a bit more stable.
However, the force directed graph is always moving in contrast to the Gephi algorithm which finds nodes stable positions
Reflection on the VR software with bigger graphs
I have been trying to implement scaling the environment(mainly the graph) using the two congrollers (similar to what we did during the in-class activities on other vr software). However, some of the script I found on the internet have been not working.
One of the example I found was this script.
3/11/2023 - 2.5hrs

Seven Scenarios
Understanding environments and work practices (UWP)
Understanding the work, analysis, or information processing practices by a given group of people with or without software in use.
Evaluating visual data analysis and reasoning (VDAR)
assess a visualization tool’s ability to support visual analysis and reasoning about data.
Evaluating communication through visualization (CTV)
the goal or purpose to convey a message to one or more persons, in contrast to targeting focused data exploration or discovery. Their effectiveness is usually measured in terms of how effectively such a message is delivered and acquired.
Evaluating collaborative data analysis (CDA)
Evaluations in this group study how an information visualization tool supports collaborative analysis and/or collaborative decision-making processes. Collaborative sys- tems should support both taskwork, the actions required to complete the task, and teamwork, the actions required to complete the task as a group
Evaluating user performance (UP)
Evaluations in the UP group study if and how specific features affect objectively measurable user performance.
Evaluating user experience (UE)
Evaluation of user experience seeks to understand how people react to a visualization either in a short or a long time span.
Evaluating visualization algorithms (VA)
Evaluations in the VA group study the performance and quality of visualization algorithms by judging the generated output quantitatively. A visualization algorithm is broadly defined as a procedure that optimizes the visual display of information according to a given visualization goal.
Started Ideation for second/ final project
Idea 1
Evaluating Collaborative workspace for architecture 3d space modeling
Seven Scenarios in terms of Project 2 idea 1
From UWP:
What is the context of use of visualizations?
3D rendering of an architecture is sometimes not enough to give a sense of scale as well as perspectives.
From VDAR:
How does it support processes aimed at seeking infromation, searcing, filtering, and reading and extracting information?
The VR visualization of the architecture project enables extracting spacial information easier with realistic analysis of light, reflection, as well as potential material choices.
From CTV:
Do people learn better and/or faster using the visualization tool?
Having a VR space where people/stakeholders can experience the space instead of 3d rendering/floor plans will make the process of understanding the space faster.
From CDA
Does the tool support effective and efficient collaborative data analysis?
If some of the existing softwares provide mutiplayer feature, yes.
From UP
How does one visualization or interaction technique compare to another as measured by human performance?
Comparison of overall structure understanding using floor plan vs. the vr experience can be done
From UE
Is the tool understandable and can it be learned?
intuitive architecture rendering VR software should be able to provide an intuitive way to nagivate through the space.
From VA
N/A
Project 2 idea 2

Worked on Ideation for Project 2. Looked at serveral project pages as well as Online resources for potential APIs, softwares, and others.
Project 2 Idea: Collaborative VR Workspace User Experience Analysis
Project Name: Collaborative VR Workspace User Experience Analysis
Motivation: Although there are pages on Collaborative VR software and Collaborative workspaces in the wiki, there is no analysis of VR collaboration user experience, nor is there any comparison of collaboration using the Seven Scenario Analysis.
Project Description: Evaluate the current state of Collaborative VR spaces for science and other applications. Potentially conduct in-depth research on collaborative communication and interaction experiences in VR space and propose new techniques to improve the collaborative VR experience.
