[x3d-public] Mantis 667: Sensor nodes missing description field

[Brutzman, Donald (Don) (CIV)]

Here are the affected nodes.  Of note from a user experience perspective:
descriptions by the author make sensing sensible to the user.

 

	
The initial list for X3DSensorNode is taken from relevant node hierarchy
(link follows).  I also did a search through schema to find many locations
where the descript field is already found.

Subject: Mantis 667: Sensor nodes missing description field

 

Resolution of a simple yet important item seems to have eluded us earlier.
Reported here for possible followup comment.

 

*	Mantis 667: 7.3.7 - Need description field for all X3DSensorNode
*	https://www.web3d.org/member-only/mantis/view.php?id=667

 

Mailing list discussion reported this expected development without further
comment:

*
http://web3d.org/pipermail/x3d-public_web3d.org/2018-December/009765.html

 

X3D4 Architecture Specification:

*	X3D4 Architecture, Core component, 7.3.7 X3DSensorNode
*
https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-CD1/Part01/
components/core.html#X3DSensorNode

 

Allowing authors to include a description on each sensor node allows them to
communicate intent to end user, and allows browsers to present such
descriptions as part of the user interaction. Seems sensible and necessary.
As an example, a description field is included in 

 

*	X3D4 Architecture, Sound component, 16.4.14 MicrophoneSource
*
https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-CD1/Part01/
components/sound.html#MicrophoneSource

 

It also might be be a good security practice for browsers to also notify
users when a sensor is active.  We'll consider wording on this.

 

all the best, Don
