Sum2003-M5: Slide Shows with Sound

Add a second way to create a slide show. create:withMusic: accepts a directory (as with create:) but now also accepts specification of a MIDI or MP3 file to be played in the background as the slide show plays. A third way to create a slide show createWithMusic: accepts only a directory but associates background music specified with the ordering information in the directory.

In edit mode, allow the user to specify a textual annotation or a recorded sound (sound file) associated with individual slides.

If textual annotation is entered, then that text should appear as a caption under the image during slide show and the textual annotation should be spoken by the system using text-to-speech translation. (If you want, you can give the user a choice of voices.)
The user should also be allowed to specify an .aif or .wav file as a recorded sound associated with the slide or record a sound in edit mode to be associated with the given slide. Save the recorded sound in the directory.

All of this information should be saved along with the ordering information in the directory: the background music, and the annotations (textual or recorded sound). Save the information even if the ordering tool isn't opened: Whenever an annotation is entered and the slide is saved, save the ordering and annotation information.

Also, add a button to translate your slide show with sound into a set of html pages. The pages should play the annotations and sounds associated with the images. The html pages should have next and previous buttons to move along to the next slide. Of course the order of slides in the html pages should match the saved order.

There are lots of details to get right here:

The annotation takes precedence over the slide show delay. If the slide show delay is only 5 seconds, but the annotation takes 7 seconds to play, the annotation should complete before the slide transition takes place.
The user can have both annotations and background music. Make sure that they both play.
Slides take precedence over the background music. If the slide show ends, and the music isn't ended yet, cut the music.

Once you have finished M5 you might even want to share your new tool with your friends. Check out http://minnow.cc.gatech.edu/squeak/778

Ask Questions on Summer 2003 M5 Milestone

Turn-in your code using the Summer 2003 Turnin Information with the code 'M5'. Turn in a sample directory using background music, text annotations, and sound annotations as a zip file. (Please make sure that all the media is rated 'G' and could be played on network television during the Family Hour.) Turn in your design in-class. Each team must also demonstrate the working program to their TA!

Summer 2001 CS2340 did movie editors (instructed by your fearless TA Lex Spoon) and Spring 2002 did campus maps with text-to-speech tour information. Examples of both projects with working code that you're welcome to steal, er, re-use without honor code violation! are on the Case page.

Grading:

10% Good Scenarios: Accounts for all major functions in assignment, touches on every class.
10% Good CRC card analysis: Reasonable names, understandable and clearly defined responsibilities, good exploration of other class names
10% Good UML class diagram and class descriptions:
- Correct usage of notation in diagram (3%)
- Detailed and understandable class descriptions and names (7%) (Note: see http://coweb.cc.gatech.edu/cs2340/2980 for example on a general format for class descriptions)
10% Quality of the design
5% Well-documented and good style source code
55% Working system:
- 5% All of the previous functionality from M4 works.
- 5% Background music works, without conflict with other features, and gets saved appropriately.
- 10% Text annotations are entered, appear as captions, and are saved.
- 5% Text annotations are spoken during the slide show.
- 5% Recorded sound annotations can be specified as files
- 5% Recorded sound annotations can be recorded in edit mode.
- 5% Recorded sound annotations play correctly during the slide show.
- 5% The html pages are correctly generated
- 5% The sounds play correctly on the html pages

Note: If the TAs can't figure out how to do these things, they don't have to give you the points. The UI must be usable.
