JTC1/SC24 WG9 & Web 3D(January 17, 2017)
Resolution 38(Prague 2016): Establishment of AHG on environments and resources for Augmented Reality (AR) and Virtual Reality (VR)
SC36 approves the establishment of an AHG on environments and resources for AR and VR with the following terms of reference:• To investigate AR and VR technology for LET perspective• To develop standardization topics collaborating with WGs The membership of the AHG is open and this AHG expects the following activities:• Collaboration with experts of NBLOs• Initiation of webinars using ISO WebEx SC 36 appoints Yong-Sang Cho*, Toshio Okamoto and Yuntao Yu co-convenors of this AHG. SC36 instructs its Secretariat to call for experts to participate in this AHG and to request lead convenor, Yong-Sang Cho to submit a Report at the next JTC 1/SC 36 Plenary.

Case Study: VR & MR in Ed
“History-themed classes are often boring and hard-work-ing. Is there a way for students to learn history more vividly and vigorously during class? It would be nice if the students would go to the site and look around and see the teacher's explanation and answer the ques-tions. But what if you want to visit historical sites on the other side of the globe? ”
“ Have you ever dreamed of an astronaut or space scientist as a child? ”

“ Sometimes it is more attractive and efficient when the real world and the virtual world coexist than the full scale of virtual reality. ”

Consideration for adoption
of VR & MR
Category Content
Curriculum Standards VR and MR content catalog based on the curriculum con-
tent (subject) and achievement standardsi.e. recommendation among VR and AR, reference links, etc.
Content Ecosystem Replace content providing system from public institution
oriented development to private sector investment based on license purchase
Role of School & Teacher
Prepare experience spaces and community Participation as maker
Connection to Learning Analytics
Standardization issues related to connection with learning ana-lyticsi.e. extension of learning activity data collection standards (in-teraction & behavior model, etc.)
Human Factor Guideline Health, safety, and social issues, etc.
i.e. discomfort(motion sickness, dizziness), misuse, and de-humanization, etc.
Issues related to VR & MR
“ Some people may feel dizzy or embarrassed when they watch content that uses HMD. Why? ” –
‘VR sickness’, ‘simulator sickness’, ‘motion sick-ness’
“ If I use an HMD, is it OK to see the screen close to my eyes? ”
Health Issues
• Dizziness, headache, nausea and even vomiting symptoms,
• The HMD is a type that is closely attached to the user's eyes
and transmits light through the eyes,
• And Photosensitivity Syndrome (Pokemon or Nintendo Syndrome)
“ If you walk around with the HMD, you may hit the wall, or get caught in the line and fall. Be especially careful when using it while walking or driving. ”
“ Is this real? Is it a virtual world? It can be confusing if you get too immersed. ”
Safety Issues
• VR and MR technology reflects positional tracking that is not only head movement and direction but also position and posture in content experience,→ Excessive movement can cause user to fall on the line or collide with nearby objects
• Virtual world and real world confusion→ Leaning on a desk that is not real, falling down or dropping a real vase, etc.
“ Does new technology be used only for its original pur-pose? Why this technology is used it in places you have not thought of? Can we deal with new technologies like curious kids who can get away anywhere? ”
Misuse Issues
• Google Glass Issue : sensitive personal information leakage,
privacy invasion, etc. • Pokemon Go : to collect Pokemon, infringement of private land
or crime of attraction
• Ethical Issue : Pokemon characters appear in an inappropriate
place like Holocaust Memorial Museum, Auschwitz Jewish concentration
camp in Poland, Arlington National
Cemetery, etc
• Reset syndrome, etc
< Koffing in Holocaust Memorial Museum >
“ If someone enjoy content alone in a virtual environment, does it intensify the phenomenon of dehumanization caused by lack of human communication? ”
Dehumanization Issues
• Possibility of mental and psychological pathologies such as withdrawal symptoms and escape of reality→ When exposed to powerful stimuli, the real world becomes somewhat uncomfortable and frustrating, and falls into helplessness (similar to game and Internet addiction)
The Other Issues
• Hygiene problems that can occur when using common equipment
• Accessibility issues (no way to provide alternative experiences)
Reasons and Measures
of Human Factor
Category Content
Health Issues
<Hardware Issues> (Reason) low level of video transmission per second
(Measure) higher than 90Hz/fps processing (Reason) display delay
(Measure) faster than 20ms response speed (Reason) Head tracking sensor response delay
(Measure) Minimize response delay (Reason) No motion and position sensors
(Measure) Utilize HMD external sensors<Content Issues> (Reason) Content design that causes cognitive dissonance (such as screen
switching that is more severe than body movement) (Measure) Develop content modeling and guideline
Safety Issues
(Reason) See-Closed type device(Measure) Use See-Through type or hybrid type of See-Through and See-Closed
(Reason) Reality and virtual world chaos due to immaturity of cognitive structure(Measure) Observation and attention before / during / after each stage
Misuse / Dehumanization
(Reason) User aspects such as excessive immersion and abuse, and content as-pects such as violent and tempting scene(Measure) Ethics and Prevention Education Program
Accessibility and others (Reason) Unequal educational opportunities and lack of content budget
(Measure) Develop inclusive design technology to provide alternative experience
