Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent handle relative directions by reference frame, conventions and translation into absolute directions.

A direction defined relative to an observer or object, such as left, right, forward, backward, up and down, as opposed to absolute directions such as north and south; related systems include points of sail and traffic direction.

What it is for: Giving and following directions and describing orientation.

It can be give clear directions; convert relative to absolute directions; handle left and right conventions; describe orientation in sailing or traffic.

Distinguishing features

Depends on the reference point

Changes as the observer turns

Contrasted with absolute directions

Language conventions differ

What it looks like

Words and arrows indicating direction relative to a viewpoint.

How it is recognised

Left, right, ahead, behind

Port and starboard at sea

Some languages prefer absolute directions

  2. Should landmarks be added? action

Accessibility

Needs.

Accessibility

Accessible directions.

  1. Are directions usable by blind or low-vision people? boundary
  2. Do they use clock-face or tactile cues? definition
Domains Special systems.

Domains have conventions.

Nautical

Port and starboard.

Nautical

Nautical directions.

  1. Which nautical terms apply? definition

  2. What should visitors watch for? action
Language Cultures.

Languages differ.

Systems

Relative or absolute.

Systems

Linguistic systems.

  1. Does the language prefer relative or absolute directions? provenance
  2. How does that affect translation? boundary

Confusion

Left-right.

Confusion

Left-right confusion.

  1. How can left-right confusion be reduced in safety-critical tasks? action
  2. Which checks help? action

What the second pass must settle

  • Should nautical directions be separate entries?
  • How should language differences be recorded?
  • How should reference frames be specified?
