INSTRUMENTAL INTERACTION

POLYMORPHISM

▸ The same tool can be used 


in different contexts

▸ Example : color selector ▸ Change color of:


Text
 Border
 Background
 Highlight
 …

INSTRUMENTAL INTERACTION

POLYMORPHISM

▸ The same tool can be used 


in different contexts

▸ Example : color selector ▸ Common examples:


Open, cut, paste, delete, move

▸ Apply command to group:


apply to each object, if meaningful

▸ Free the tools from the

applications where they are trapped!

INSTRUMENTAL INTERACTION

REUSE

▸ Output reuse (objects) ▸ Example : copy-paste, duplicate

INSTRUMENTAL INTERACTION

REUSE

▸ Output reuse (objects) ▸ Example : copy-paste, duplicate ▸ Input reuse (commands) ▸ Example : redo, history, macros

INSTRUMENTAL INTERACTION

ANALYZING STICKYLINES

▸ Reification of alignment ▸ Polymorphic ▸ Align objects of different types ▸ Move command adds/removes


  • bject to/from StickyLines

▸ Reusable ▸ Copy StickyLine (with objects) ▸ Copy tweaks

INSTRUMENTAL INTERACTION

INTEGRATING THE PRINCIPLES

▸ Reification and polymorphism: ▸ More objects and fewer commands ▸ Reification facilitates output reuse: ▸ More first-class objects can be reused ▸ Polymorphism facilitates input reuse: ▸ Increases the scope of commands

STYLES

▸ Reification 


  • f a collection of attributes

▸ Polymorphism ▸ Apply style to different objects ▸ Reuse ▸ Extract style from object ▸ Apply to other objects

INSTRUMENTAL INTERACTION

EXERCISE

▸ Work in groups and use last week’s homework ▸ Identify tools that are common between the applications

you analyzed

▸ Pick tools that seem specific to an application,


and see if you can make them useful in the others
