Findings

The "Findings" page was written to design a user study on currently available VR software, hardware, and media. We gathered data to understand where to improve in terms of getting people interested and excited about VR and to help formulate an assessment of currently available VR software, hardware, and media. We documented our process and results here. We also summarized our findings in a Medium article.

IV. Notes from David Whitney

@Linda + Ankita

Process:

  • IRB review

    • Confirm study is ethical

    • Takes about 10 days

    • They typically send revision suggestion

    • Talk to David!

  • Worked with psychologist in HCRI (8th floor of scili)

Type of Study

  • Within: when everyone does every part of interface/modality

  • Works for less people? 30 people is a good number

  • Remember to randomize order to reduce bias

Recruiting

  • Posters in several places in CIT, faunce

  • Emails (listserv or Today@Brown)

  • Offered money for incentive

Relevant Info Taken into Consideration

  • Reported users’ age (Year in school?)

  • Background info about their experience with VR

  • Gender; make the response text area

  • Did you have corrected normal vision? (Contacts, glasses, color vision issues i.e. I am color blind: yes or no)

  • In your prime, how many video games did you play?

Objective Measurements

Looking Back

  • Randomization

    • Make sure to have equal sizes for both groups.

    • Having a larger sample size (changed from 18 to 32).

    • Recruit cap sized people for diversity (e.g. 5 people)

Representation of Data

  • Graphs

    • (i.e. bars, cat and whisker style plots, tables, pie charts).

  • Differences in time and accuracy.

Evaluation/Forms of Assessment/Questions

  • Google form to fill out subjective questions in the end

    • highly suggested to have them digitized in a form!

    • Most of the questions were likert scale https://www.simplypsychology.org/likert-scale.html

      • rank / rate in a range

    • Did you have experience with VR; Scale of 1-7 how much do you agree with this statement -

    • Which of these did you prefer or enjoy the most?

Location of Findings

  • In “Discussion or Analysis” mention anecdotes you got from free-response answers to open-ended questions

    • Evidence of an explanation (this condition didn’t perform as well as it would. Our hypothesis was...our results suggest that…users reported…in such and such evaluation...)

Accessibility

  • Ask users if they are color blind, have had any hand injuries

  • Take into account hand sizes/head sizes

VI. Workshop Details

@Linda + Ankita

All this info is on this doc!

Logistics

  • 30 people - 6 groups of 5 people!

  • Science Center

  • Tentative Date - 5/7

    • 2 hours: all groups do all 6 activities

    • 1 hour: randomly assign 3 activities to each group

TODO

  • Should get the required approvals for user study soon!

  • Look at VR Media doc

    • Obtain Google Cardboards

  • Book Science Center

  • Ask for volunteers for this workshop/setup

  • We should get fooood!

  • Start putting together comprehensive surveys for each activity

    • Put them in a place that people can access

  • Sign-up sheet:

    • Concentration

    • School

    • Year

    • Experience with VR

    • Allergies

    • Email

  • People should know what groups they are in before they come to the workshop

  • Schedule a dry run -- make sure this is a feasible workshop in terms of time!!!

    • Confirm locations for each activity

    • We should do each activity and come up with final documentation/instructions for each activity

    • Make sure people have enough time to do each survey after each activity well

Available Tutorials

  • Hack@Brown A-Frame - located in Home/Workshops

  • Hello World Google Cardboard in Unity - located in Home/Tutorials

  • Blender (might be too much time)

Advertising

  • Facebook Event

    • Hack@Brown + Mosaic collaboration?

    • Need a fun facebook banner

  • Today@Brown

Activities

  • Understand the people we are studying: 15 min + Fun Music :) + Food!!!

    • Time where they fill out a quick survey telling us about themselves

  • Software: 30 min - 3 volunteers + 2 instructors for each

    • Hello World Google Cardboard in Unity

    • VR scene in web browser using A-Frame

  • Hardware: 50 min - each person would get 10 min - 2 volunteers (or hopefully 30 min if 2 people can go at a time/ we use more than one vive)

    • Play a game without any instruction

      • Vive - Graphics Room! + Robotics Room!

      • Would be awesome if we could have two people go at a time!

  • Troubleshooting: 15 min - 3 min for each problem!

    • Identify a few (5) common problems

      • We can crowdsource for this

  • What are these applications used for?: 15 min - 5 min for each application

    • Unity

    • Blender

    • Vive

  • Media Lab Experiment: 15 min - 5 min for setup, 10 min to watch the film

Format

  • Hardware + Activity below it can be paired together

VII. Workshop Details (cont.)

@Linda + Ankita

Linda and I felt it would be easier to organize our thoughts in a Google Drive folder.

VIII. Data Representation (Brainstorming)

@Linda + Ankita

1. Understand the people we are studying

  • Pi chart: Background, School, Year, Gender, Age

  • Bar graph: Granoff, YURT

  • Pi chart: How many of our participants that go to Brown considered or are taking VR classes?

---

  • Workshop demographics: what schools did our participants come from, age, etc.

---

  • Score participants on how “perfect” they are for VR (to calculate ideal user of VR)

    • Scale, from least likely to enjoy VR (has hand injuries, wears glasses etc.)

---

  • Word cloud representing textual data (Awareness)

2. Software

  • Pi chart: Experience with Unity and A-Frame

  • Word cloud: frustrations, things that were not intuitive with software - also helpful for findings

  • “How easy was it for people to use this software?”

  • Pi chart: Retention - would people use this software again - how great was the experience

3. Hardware

  • Pi chart: Experience with HTC Vive

  • How easy was it to use? (Most participants found it to be...)

  • Word cloud: frustrations

  • Overall experience - helpful for findings -- how people approach VR, what are people trying to achieve

    • How successful were you in accomplishing what you were asked to do

  • Retention - would people use the Vive again

  • How easy is it to use?

    • How many people found it complicated to use

    • How many people imagine that it is quick to use

  • Do people feel safe?

4. Troubleshooting

  • How easy was it for people to resolve commonly encountered problems

  • What is the common pattern people take to fix the problems

  • Word cloud to describe the process of troubleshooting

  • Suggestions on improvement to enhance experience overall

5. What are these applications used for

  • Was the purpose/typical use clear? (bar graph)

  • Would you consider using this for the field you’re interested in? (bar graph)

  • Why do you think you were unaware of the use of each app? (word cloud)

  • How should the industry improve to make it more accessible for people? (word cloud)

6. Media Lab Experiment

  • How did you feel & would you do this again (x,y axis with x = yes/no and y = range of emotions from bad to good)

  • How would you improve this experience (word cloud)

  • Did you feel like you were physically there, was it comfortable, similar to viewing a documentary film (bar graph)

  • Journalist, theater spectator images and showing which ones people are more leaning towards (maybe a scale and weights labeled each?)
