Question

Why is the basic undo requirement inconsistent for systems with more than two states?

a.

It only works for systems that perform virtually no commands.

b.

The undo command cannot undo itself in such systems.

c.

It results in a toggle behavior between two states.

d.

It only considers the last command and not the whole history.

Posted under Human Computer Interaction

Answer: (c).It results in a toggle behavior between two states. Explanation:The basic undo requirement becomes inconsistent for systems with more than two states because it results in a toggle behavior between two states. The undo command undoes the previous command, but it also undoes itself when applied again, leading to a flip-flopping between the states.
