2018 EDU: WW: PEOPLE: Social 3D and all that other stuff (VR, Virtual Worlds, etc)

Social 3D and 
all that other stuff 
(VR, Virtual Worlds, etc.)

Updated 8/17/2018
Computer simulated virtual environments are becoming easily available at low cost. They have long been available in computer games, but those are of interest only to gamers, mostly young.  Adults are more interested in social activities, either directly productive (business, education), or for entertainment (music, stage performances, travel).

Another sample of social 3D

  • Visit a virtual train station (on your desktop).
  • Click on the screen to go 3D.  
  • The little half-circle at the bottom of your screen represents you. 
  • If there are other people there, they may appear as a box with a picture.
  • In social 3D people are usually represented as avatars.
  • (Registered users can provide a picture.) 
  • Move your cursor sideways to look around
  • Press the keyboard up-arrow to move forward
  • If you see something interesting, hover the little red circle on it.
  • It may do something if it sees you looking at it.
  • Press Esc to get back to old 2D controls.

VR: virtual reality

Virtual reality (VRis an interactive computer-generated experience taking place within a simulated environment, that incorporates mainly auditory and visual, but also other types of sensory feedback like haptic. -- Wikipedia

Computer-simulated environment


  • The more realistic the simulation, the more specialized equipment is needed.
  • A binocular headpiece is needed for stereoscopic vision.
  • Special gloves are needed for haptic feedback.
  • VR seems to be used especially to refer to stereoscopic display.
  • This focus may be a marketing ploy--an ordinary computer can render 3D places.
  • Presenting a stereoscopic view requires a headpiece and new software.
  • Virtual 3D views have been available in games and Second Life for years.
  • Virtual 3D views can now be rendered in a browser.
  • A virtual 3D view creates the 3D impression when the user changes perspective.
  • The user (usually represented by an avatar) can seem to walk around.
  • Other avatars (representing users) can also move around in the 3D space.

Social 3D (VR,  etc.): what do we do? 

  • The grid of the things as they are: grid. It's all about people
  • Social: People interacting
  • Social VR (or 3D) may be called a Virtual world 
  • Because it presents an environment much like the world we live in.
  • Social 3D differs from social game VR in that its focus is not limited to games.
  • People may play social games in social 3D, but that is just one of the possibilities.
  • Other possibilities include education, art, video production, and hobbies.
  • And stage performances such as music, ballet, comedy.
  • Essentially, it can have most of the things we do in the world we grew up in.
  • Except for work and the burdens of travel.
  • We generally use voice and text for inworld communication.
  • G+ communities, Skype, and Discord for outworld communication 

The promise of stereoscopic vision ("The future of VR") 

  • 3D film
  • 3d stereoscopic video
  • As shown above, "ordinary" 3D has been around for years.
  • It requires no new hardware, not even a graphics card.
  • From standpoint of the hardware maker, stereoscopic 3D is more interesting.
  • It needs a stereoscopic headpiece and probably an expensive graphics card.
  • More profit per item.   But maybe not mass market.
  • And "ordinary" doesn't lead to a good sales pitch, anyway.
  • But how much do we need stereoscopic vision in social activities?

  • Web-worlds, 3D virtual worlds running in a browser. Summary
  • Web-worlds are small and run in a browser with nothing else to install.
  • Full virtual worlds are a bigger experience but need extra software installed.
