A Small Idea ...

Project

Our objective is to make a portable device that will transparently control devices that are attached or running on the personal computer.

The Idea

Use radio transceiver to communicate between PC and handheld PC

The handheld PC will be able to manage certain external devices and internal software on the PC

Application

CD Player

Identification Card

Device Controller

CD Player

Be able to play the CD Player on the PC from the handheld PC

Identification Card

Be able to: store information on the card

retrieve and update information on the card from the handheld PC

download the information from the handheld PC to the database on the PC

Device Controller

Simulate applications that can be connected to the serial or parallel ports on the PC

Test the simulation by connecting a LED to the different ports and controlling the LED by the handheld PC

Team Member Responsibilities

Chris Connection of LED to different ports Make applications that light up the LED Radio Frequency Communication

(sending and receiving data) Application on the handheld PC that

sends appropriate data

Vanessa Device Controller for the PC that reads

data from the serial port and sends that data to the right application

Radio Frequency Communication - application that sends and reads the right data through the radio

Kaori Revision of CD Player Code Programming Smart Card Application that interprets the

information sent by the reader Application on the PC that interprets

data from the handheld PC
