A Scenario

Introduction to HACS

• What is HACS?– Acronym for Home Appliance Control System

– Integrates wireless devices and home appliances

• Purpose of HACS– Enables users to remotely control home

appliances using their wireless devices

SAVES TIME & RESOURCES!!!

Overview of HACS

Cell Phone

PDA

Oven

TV

Alarm

Overview of HACS (contd.)

• It is a system controlled by remote devices like:– Cell phones

– PDAs

– Palm tops

– Laptops etc.

• In turn it controls, monitors and co-ordinates home appliances like:– Air conditioner

– Alarm

– Oven

– TV etc.

Why HACS will work

1. Two places at once

2. Saves time

3. Save money (Long run)

4. Self Maintenance

5. Laziness

Assumptions

• User can operate computer, WAP enabled mobile phone, or a PDA.

• Servers are always on.

• Communication Link.

• Appliance are assumed to be on and in working condition.

Interaction Diagrams

• Model the dynamic aspects of a system. • Show the interaction of any kind of instance in any

view of a system’s • Architecture (classes, interfaces, components, and

nodes).• Model the system as a whole.• Are attached to use cases to model a scenario

Sequence diagram• Emphasizes time ordering of messages.• Depicts the lifeline of objects.

Collaboration diagram• Emphasizes structural organization.• Potentially easier to model complex interactions

Statechart Diagram

• Shows a state machine, consisting of states, transitions, events, and activities.

• Represents the dynamic view of a system.

• Models the behavior of an interface, class or collaboration.

• Emphasize the event-ordered behavior.

• Useful for reactive systems.
