A collection <code>COL</code> is temporally stuff-like just in case every purely temporal part (see <a href="http://sw.opencyc.org/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a>) of an instance of <code>COL</code> is itself an instance of <code>COL</code>, unless it is a temporal part of a temporal granule of <code>COL</code> (see <a href="http://sw.opencyc.org/concept/Mx4rvVjaJJwpEbGdrcN5Y29ycA" class="cyc_term">granuleOfTemporalStuff</a>). More precisely, for a collection <code>COL</code> to be an instance of <a href="http://sw.opencyc.org/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a> it is both a necessary and sufficient condition that for any <code>OBJ1</code> and <code>OBJ2</code> (with <code>OBJ2</code> at or above <code>COL</code>'s temporal granularity level), if <code>(<a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ1 COL)</code> and <code>(<a href="http://sw.opencyc.org/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a> OBJ1 OBJ2)</code>, then <code>(<a href="http://sw.opencyc.org/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ2 COL)</code>. Consider <a href="http://sw.opencyc.org/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>. Take an arbitrary instance <code>WALK</code> of this collection (say Miss America 2000's victory walk down the runway and back); and then take an arbitrary time-slice <code>SUBWALK</code> of <code>WALK</code> that subsumes at least one instance of (the <a href="http://sw.opencyc.org/concept/Mx4rvVjaJJwpEbGdrcN5Y29ycA" class="cyc_term">granuleOfTemporalStuff</a> for <a href="http://sw.opencyc.org/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>) <a href="http://sw.opencyc.org/concept/Mx4rvViYBpwpEbGdrcN5Y29ycA" class="cyc_term">TakingAStep</a> (say her trip back from the end of the runway). <code>SUBWALK</code> is itself an instance of <a href="http://sw.opencyc.org/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>. So <a href="http://sw.opencyc.org/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a> is an instance of <a href="http://sw.opencyc.org/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a>. See <a href="http://sw.opencyc.org/concept/Mx4rvViq35wpEbGdrcN5Y29ycA" class="cyc_term">TemporalObjectType</a> for the disjoint notion of being temporally object-like. VirtualReality A hypothetical three-dimensional visual world created by a computer; user wears special goggles and fiber optic gloves etc., and can enter and move about in this world and interact with objects as if inside it. virtual reality SpatiallyDisjointObjectType type of object whose instances do not physically overlap A collection of collections and a specialization of <a href="http://sw.opencyc.org/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a> (q.v.). Each instance of <a href="http://sw.opencyc.org/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg" class="cyc_term">SpatiallyDisjointObjectType</a> is a collection C of spatial things (see <a href="http://sw.opencyc.org/concept/Mx4rvVjpUZwpEbGdrcN5Y29ycA" class="cyc_term">SpatialThing</a>), where each of the spatial things in C is spatially disjoint with the other spatial things in C. For example, the collection <a href="http://sw.opencyc.org/concept/Mx4rvVjaoJwpEbGdrcN5Y29ycA" class="cyc_term">Dog</a> is an instance of <a href="http://sw.opencyc.org/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg" class="cyc_term">SpatiallyDisjointObjectType</a>, since dogs do not spatially overlap. Even pregnant dogs do not spatially overlap the pups they bear; rather, pregnant dogs contain their unborn pups. Other instances of <a href="http://sw.opencyc.org/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg" class="cyc_term">SpatiallyDisjointObjectType</a> include <a href="http://sw.opencyc.org/concept/Mx4rwVGrQ5wpEbGdrcN5Y29ycA" class="cyc_term">LatitudeLine</a>, <a href="http://sw.opencyc.org/concept/Mx4rvW4n1pwpEbGdrcN5Y29ycA" class="cyc_term">CompactDisc_Audio</a>, and <a href="http://sw.opencyc.org/concept/Mx4rwR7UWZwpEbGdrcN5Y29ycA" class="cyc_term">PlanetaryBody</a>. An important specialization of <a href="http://sw.opencyc.org/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg" class="cyc_term">SpatiallyDisjointObjectType</a> is <a href="http://sw.opencyc.org/concept/Mx4rvVjlE5wpEbGdrcN5Y29ycA" class="cyc_term">SpatiallyDisjointRegionType</a> (a collection of specializations of <a href="http://sw.opencyc.org/concept/Mx4rvViACZwpEbGdrcN5Y29ycA" class="cyc_term">GeographicalRegion</a>, such as <a href="http://sw.opencyc.org/concept/Mx4rvVjnZ5wpEbGdrcN5Y29ycA" class="cyc_term">City</a> and <a href="http://sw.opencyc.org/concept/Mx4rwT-n15wpEbGdrcN5Y29ycA" class="cyc_term">TrueContinent</a>). wikipediaArticleName (<a href="http://sw.opencyc.org/concept/Mx4rTv-jk9SPTXa991kk5mAvHg" class="cyc_term">wikipediaArticleName</a> THING NAME) means that in <a href="http://sw.opencyc.org/concept/Mx4rtqXA6OC8QdiWC72DuLJdUw" class="cyc_term">Wikipedia_WebSite</a> THING is described by an article with the title NAME Wikipedia Article Name visual information source A specialization of both <a href="http://sw.opencyc.org/concept/Mx4rvjSBSZwpEbGdrcN5Y29ycA" class="cyc_term">Artifact_Generic</a> and <a href="http://sw.opencyc.org/concept/Mx4rvkNufpwpEbGdrcN5Y29ycA" class="cyc_term">InformationBearingThing</a>. Each instance of this collection is an artifact from which information is extracted by viewing it (note that a viewer may need to be familiar with an appropriate set of interpretive conventions in order to do this). Examples of <a href="http://sw.opencyc.org/concept/Mx4rvVjPtpwpEbGdrcN5Y29ycA" class="cyc_term">VisualInformationBearingThing</a> include handwritten letters, newspapers, sculptures, television sets, and neon signs. (Thus, the information content of <a href="http://sw.opencyc.org/concept/Mx4rvVjPtpwpEbGdrcN5Y29ycA" class="cyc_term">VisualInformationBearingThing</a>s may or may not be propositional in nature.) In the proper conditions, instances of <a href="http://sw.opencyc.org/concept/Mx4rvVjPtpwpEbGdrcN5Y29ycA" class="cyc_term">VisualInformationBearingThing</a> produce instances of <a href="http://sw.opencyc.org/concept/Mx4rvVkL2pwpEbGdrcN5Y29ycA" class="cyc_term">VisualImage</a> (which, unlike instances of <a href="http://sw.opencyc.org/concept/Mx4rvVjPtpwpEbGdrcN5Y29ycA" class="cyc_term">VisualInformationBearingThing</a>, are instances of <a href="http://sw.opencyc.org/concept/Mx4rvViADZwpEbGdrcN5Y29ycA" class="cyc_term">Event</a>). For example, if one shines light on a photograph, a characteristic <a href="http://sw.opencyc.org/concept/Mx4rvVkL2pwpEbGdrcN5Y29ycA" class="cyc_term">VisualImage</a> is produced. Likewise, if one electrifies a neon sign, a <a href="http://sw.opencyc.org/concept/Mx4rvVkL2pwpEbGdrcN5Y29ycA" class="cyc_term">VisualImage</a> is produced. A notable specialization of this collection is <a href="http://sw.opencyc.org/concept/Mx4rv_W6CJwpEbGdrcN5Y29ycA" class="cyc_term">StillImageSource</a> -- sources of <a href="http://sw.opencyc.org/concept/Mx4rvVkL2pwpEbGdrcN5Y29ycA" class="cyc_term">VisualImage</a> that do not move (which thus includes all the examples of <a href="http://sw.opencyc.org/concept/Mx4rvVjPtpwpEbGdrcN5Y29ycA" class="cyc_term">VisualInformationBearingThing</a> given above except for the television set).
