Lecture 22- Wayfinding Flashcards
What is wayfinding?
Moving through space, distinguish from navigation as this involves technology/satellites
What is deduction?
Based on Forms and Rules (Symbolic AI)
What is induction?
Pattern Finding (Neural Networks)
What is abduction? Can computers do it?
- “Guessing”
- Generating a hypothesis of what caused it or what the story is
- Computers can not do this (why we can’t talk to computers)
What can wayfinding be….
- From one known place to another (not just vast distances)
- Discover unknown places (at least by you)
- Can be solo or in a group (waka)
- Can be for hunting or scavenging+ collecting resources
Examples of wayfinding….
- Visiting friends
- Going to class across town
- Getting from your chair to the bed.
Is wayfinding embodied and situated?
Yes
Describe Inuktitut wayfinding…
- Winds (feel)
- Rocks with lichen patterns
- Snowdrifts against rocks
Describe Maori ocean wayfinding…
- Winds
- Ocean swells (look and feel) based on how close to islands
- Homing birds
- Reflections and shapes of clouds
How can names help with wayfinding?
- Some describe the actual thing
- Some are just names don’t tell you anything unless you have previously memorized their meaning
- Knowing names help success in wayfinding
What does a clear place help us remember?
The story
What parts of the brain do wayfinding?
- Hippocampus
- Entorhinal cortex
Both low and inferior in the brain
What are some cells/neurons invovled in wayfinding?
- Place Cells (Hippocampus)
- Grid Cells (Entorhinal)
- Boundary Cells (Subiculum)
- Head-direction cells
- Speed Cells
What are three things Boundary cells are invovled in?
- Scale (distance)
- Orientation
- Phase (how they overlap)
How are the different cell types tied together?
- Grid is based on head-direction and boundaries
- Place cells tied to grid
All together invovled in mapping out places
