Correspondence

Author: Philip Dorrell

Correspondence is a framework for interactively visualizing correspondences between items in related blocks.

Move your mouse over the blocks below, and see what happens.

Spanish

¿ Cuál prefieres ? Me gusta el verde .

English

Which one do you prefer ? I like the green one .

Literal English

Which you prefer ? The green (one) pleases me .

Only show correspondences if Ctrl key pressed or held down

(Hint: to de-select without selecting a new item, click anywhere not inside a selectable item.)

Explanation

Typically two blocks might be related by translation. For example,

Translation between English and another natural language
Translation between English and a programming language
Translation between English and mathematical formulae
Translation between English and items in a diagram

(If you speak some language other than English, substitute your preferred language in the examples above.)

An Abstract Example

The basic concepts of Correspondence are translations, blocks and items.

The following example shows a translation consisting of two blocks, block A and block B, each containing three items. In block B, the first item is split into two parts.

Block A: Item 1, item 2 and item 3.

Block B: This second block contains its own representations of the three items: the first part of item 1, item 2, the second part of item 1 and item 3.

The Spanish, Ruby, rhoScript and Māori examples have been coded using Bracketup.
