Spatial cognition is foundamental
8Question
- Human intelligence is_a Slow Intelligence System
- Spatial intelligence is foundamental to human
intelligence - Slow Intelligence System has_a architechture
- Is it possible that spatial intelligence be
simulated within the SIS architechture?
9SIS for Spatial Knowledge within a Scene
- A picture on a wall
- A lady in the picture
- The lady is back to us
- A gentalman is near the picture
- The gentalman is at the left side of the picture
10SIS for Spatial Knowledge within a Scene
- Object categories
- A picture
- A lady
- A wall
- Spatial relations
- On, in
- Back, left
- Near
11Specific Question
- Object categories
- A picture
- A lady
- A wall
- Cross linguistic spatial relations
- in, on, near, front, left,...
- ?,?,?
?
12Results in Psychology
- Connection relation is primitive
- Orientation and distance relations are acquired

Child. Routledge Kegan Paul Ltd. - Carey (2009) The Origin of Concepts. Oxford Press

Potential, MIT Press. - Spatial model is point-based

15Spatial Reasoning for 'one foot away'
B
Trying all possible extension (problem solving by
trying), and see whether one foot connects with
the target object (context awareness).
A
?foot foot ? FOOT ? C(A, foot) ? C(foot, B)
16Spatial Reasoning for distance in SIS
- In the UK A is one foot away from B means
region B can be reached by a region of the same
size as the British imperial foot from A. - China and Egypt
- Cun the body segment between the wrist striation
behind the thumb and the pulsing point of the
radial artery - Cubit the segment between the bent elbow and the
point of extended middle finger. - In modern physics meter, light-year.
- The meter is the distance traveled by light in
vacuum during a time interval of 1/299 792 458 of
a second

17Spatial Reasoning for distance comparison
A is nearer to B than to C there is an X such
that C(A, X) ? C(X, B) and there is no X such
that C(A, X) ? C(X, B).
Trying all possible extension (problem solving by
trying), and see whether one x connects with B
and non of x connects with C (context awareness).

18Spatial Reasoning for orientation
- A is in front of B A is nearer to the front
part of B than to its other parts.
B
A
19Spatial Reasoning for orientation
- Orientation is determined by the shape of the
reference object, and the method of distance
comparison.

20Spatial Reasoning Performance
- Performance in term of the accuracy increases, as
the number of sides of the reference object
increases.
Qualitative spatial orientation frameworks, e.g.
Frank (1992), Freksa (1992), Hernández (1994),
Freksa (1999) Renz and Mitra (2004), Dong and
Guesgen (2007)

22SIS for Spatial Reasoning for one scene Short
Summary
Context-aware (Object, Connection) Always trying
(do spatial extension) Continuously improve
performance (do adaptation)
23SIS for Spatial Reasoning between
snapshotsObject tracing
24SIS for Spatial Reasoning between
snapshotsObject tracing
25SIS for Spatial Reasoning between
snapshotsObject tracing
26SIS for Spatial Reasoning between sceneObject
tracing
- Fast changining leads to an illusion
- bird ? rabbit, rabbit ? bird
-
-
- Otherwise, bird flies, rabbit moves
27SIS for Spatial Reasoning between sceneObject
tracing
- A problem of object mapping between scenes
- Two object tracing results due to two different
priorities - Priority on spatial changes (minimal spatial
changes) - Priority on object categories (objects are mapped
within same categories)
28SIS1 for Object tracing with priority on spatial
changes
- permutation list all possible mappings
-
- eliminationconcentration choose the mapping
with the minimal spatial changes
29SIS2 for Object tracing with priority on object
category
- permutation list all possible mappings
- elimination remove mappings of different object
categories - eliminationconcentration choose the mapping
within minimal spatial changes
30Why fast changing leads to illustiion?
- Conjection SIS2 takes more time than SIS1 in
object mapping between scenes.
31Conclusion
- SIS shall be a Cognitive Architecture
- SIS for spatial knowldge acquisition within a
scene - SIS for spatial knowledge acquisition between
scenes - SIS for Spatial Cognition
- Spatial Cognition is foundamental to Human
Intelligence - SIS as a Cognitive Architecture for Human
Intelligence
32Outlooks
- Relations between SIS and other Cognitive
Architectures, e.g. ACT-R, CLARION, ... - Any difference to acquisit implicit knowledge and
explicit knowledge
