4.4.7 Mixed initiative

Mixed initiative.

User:	Third floor quickly!
System:	I'm taking you to the third floor.

The user should be able to initiate the dialogue in the way they choose. In this example no keyword has been used, but the elevator still responds appropriately.

System:	Which floor do you want?
User:	I want to go to the second floor to professor Pinkal's office.
System:	Professor Pinkal's office is on the first floor. Shall I take you to the first floor?
User:	Yes.

The user makes an inconsistent request. The elevator recognises that, lets the user know, and offers an alternative.

Current state and possibility of extension: See Section 4.5.7. See also description of elevator, Section 4.3.
