Basic components

Detailed Architecture

Analog

MP3

Slappy

Status

Cell phone UI Bluetooth interface is done Playlist is partially functional

Personal Server control Bluetooth interface is partially finished Playlist management software is in the works Working on MP3 decoding

Digital to analog to FM radio signal Acquired the Slappy card Waiting on the drivers Researching ways to implement this

Expected effort

Minimum functionality Choose song from folder on personal server Basic start, stop, pause, etc. Output song through audio output on ps

Desired functionality Playlist editor

Favorites list that you can save and load Random playback & caching on phone

Ability to drag-and-drop through Wi-Fi P2P file swapping…?

Big unknowns

Will our Bluetooth connection work? Don’t have cell phone yet Have phone emulator and Bluetooth dongle Can’t figure out how to make them work together

How do you use the serial port in Linux? Which open source MP3 decoder engine? What it’s going to take to get Slappy going?

Global MP3 – Mike Quinn & Mark Ridao CSE 476 ’02 Stream MP3’s from PS to client device Uses Bluetooth to transport data

Phone-GPS – Don Patterson & Nik Livic Use location data from GPS unit Phone displays relevant bus information Use Bluetooth communication

Burning questions

How to integrate Bluetooth control & MP3 decoder.

What MP3 engine to use. Anyone know what libraries to look at for

serial programming in Linux?

Evaluation

How would you evaluate your project? Does it play music over FM radio? Does the Bluetooth always work? Identification and security.

What performance tests are important? Are the playlist commands responsive? Can it playback in real time?

What would you want to know from user studies? What are some other features they would like? Is it stable and easy to use?
