1 Introduction

A home appliance control system (HACS) is a system which is controlled by a remote system such as a
mobile phone or a palm-top, and at the same time controls, monitors and coordinates home appliances
such as air conditioner, microwave oven, garage doors, TV set, VCR, audio controller, indoor/outdoor
lights, water sprinkler, home security system, bath tub controller, etc.


The intention of this project is to use Object Oriented Analysis Design (OOAD) techniques to design
HACS system.


The project is split into two phases:


   1. First Phase of the project should produce use case diagrams, class diagrams, and sequence
       diagrams for a home appliance control system (HACS). For the analysis phase CRC cards
       mechanism should be used as an aid.


   2. Second Phase of the project description as of September 20th 2006 is not yet posted on the course
       website. (Refer [1] for updates)




   1.1     Project Scope

   Analysis should consider at least three different kinds of home appliances.

   For the scope of this Analysis and Design, following Home Appliances are considered:

          AC Thermostat
          Microwave Oven
          Garage Door
          Audio Video Recorder / Player

Appendix A – Assumptions
      Communication between Appliances and HACS is via a common communication protocol. (
       example Bluetooth, 802.11 wireless protocol )

      Communication between Appliances is not allowed / turned off. And if two devices need to
       communicate it should go through the HACS system.

      Multiple users can access the HACS remotely.

      For ease of design All the Members of family will have same level off access to the system.

      For ease of design we will assume that HACS Support team will have same level of access to the
       HACS system as the family members.

      All the users of system will have unique userid to differentiate between login’s and access.

      All users have to enter the User Profile before using the HACS system for the first time.

          o Name

          o Userid

          o Password

          o Date of Birth

          o Security questions (city of birth, first pet’s name, best friends name)


      One or More of the following Security mechanisms will be used

          o Password

          o Voice recognition

          o Security questions specific to login ID to authenticate user.

          o Reset password every month
