Creating a New VR Experience
• Creating an experience from scratch allows the most flex ibility but will require the most effort.
The Experience Creation Process
• There are courses of action by whic h one can reduce the amount of w asted effort.
• Many successful VR experiences an
d other computer applications have
relied on user tests to hone the con
tent and the interface.
The Experience Creation Process
• Form your VR team - What people do you need?
– Programmers – Content Experts – Set Designers – Prop Creators
(theatrical property, the stage) – Sound Effect Experts
– Hardware Engineers
The Experience Creation Process
• It’s generally wise to use a software system!!
– More flexible
• Disney Aladdin VR experience
– SAL : a Development language of Disney team
The Experience Creation Process
• A Typical VR system
Designing a VR Experience
• It’s wise to approach the creation of a VR experience wit h good design practices.
Design Deliberately
• Customer Highest !!
– Design to make things easier for the user, not the pr ogrammer.
• Looking from the top down
– Design a VR experience should be constructed lookin g from the global view toward the goal.
• Don’t Just keep a particular feature. If the feature doesn
’t live up for the user’s experience, then it isn’t worth ke eping.
• Don’t forget the special features in VR
– Virtual Reality has more options than day to day reali ty.
Design with the System in Mind
• Use an existing system, or make from scratch ?
• If your project will continued for a considerable amount of time,
– You can take advantage of the fact that technology i s getting improved.
• If your project will involve large hardware
– You may convince your hardware manufacturer to let you test out the next generation of their product.
Design with the Venue in Mind
• If a venue with limited space
– Likely require a HBD (head –based) or HMD (head-mounted display)
• If the venue is theater-style
– High-resolution projection-based display
• If venue is so large that participant can roam – Non-occlusive HBD or hand-based display
Design with the Audience in Mind
• Know your audience is the most important tenet a desig ner should remember.
• NCSA’s Virtual Director application is a VR tool using wid ely for computer animation
• If General Audience
– Avoid language-based messages
– Choose internationally recognizable sounds and symb ols
Design with the Audience in Mind
• AGE : If user is child
– Head-based displays and shutter glasses may slip off
• EXPERIENCE :
– Children - Easy
– Adults – Car-like steering interface
– Videogame players – Complicated handler
• CULTURE :
– Virtual VR arcade system was being deployed in the Middle East, they discovered that most men wore a h eaddress, they could not don the standard HMD
