2018 IMA: EDU: Wanted: a virtual world viewer for education. Straw-man model

Wanted: a virtual world viewer for education: 
Straw-man model
Updated 1/11/2018
A straw-man model for a virtual world viewer is presented with the objective of eliciting comments and suggestions for improvement.  Comments and suggestions will be used to produce a more refined model.  This article is explicitly licensed as public domain.
  • A straw-man model is used to start developing specs
  • Straw-man strategy: You put it up and everyone tells you what is wrong with it.
  • Comments and suggestions will be used to produce a more refined model.

***************************

What do we need from a viewer for education and educational research?

  • Minimize viewer learning time 
  • Capability: User activity tracking.
  • Use secure, web-compatible exchange protocols (https)
  • Meet standard accessibility requirements for educational offerings.
  • Use a standard, widely taught, scripting language.
  • Provide for still and video capture. by learner, instructor, and researcher
  • Provide settings to configure for multiple learning styles.
  • Mobile device compatibility
  • Microlearning compatibility 
  • Support for individualized instruction guided by observed performance.
  • Comply with relevant industry specs.

Easy learning of viewer use

  • Cut actions to be learned to minimum needed for education:
  • Walk, talk (voice), text
  • Make friends, locate friends
  • Send and receive instant messages
  • Click objects to activate or select them.
  • Gather objects and place them (learners can build to keep score)
  • More? TBD

Accessibility requirements (TBD)

  • Text to speech (probably available)
  • Speech to text (in test on web-worlds)
  • Use only browser compatible calls 
  • More?  TBD

Desirable features

  • Optional recording to MP4
  • Recall recording: Last N minutes before an error. 
  • Small segment video recording.
  • Small segment saving for micro learning review.
  • Add drag and drop importing for images, COLLADA files*, videos, urls, and avatars.
  • *And other industry standard model formats: obj, 3ds, wrl, x3d
  • Allow user to drag windows off the viewer screen.
  • Keep compatibility with OpenSimulator, Helios, Halcyon  and Whitecoresim 
  • Integrate with web-world development (Cybalounge, Webworldz)
  • Offer optional tips on learning and web-use.
  • Provide hooks for the insertion of hand-held controls.
  • Provide a way to overlay part of the virtual world scene on a video image.
  • More?  TBD

Relevant industry specs
