* VOICE OVER (Dan): In the Computer Science Laboratory at the Xerox Palo Alto Research Center, we are developing an experimental voice management system.  This system is implemented within an integrated programming environment called Cedar.  Cedar runs on a collection of personal workstations and servers interconnected with Ethernet, a local area network.  The voice management system is a foundation for research in using voice within personal information systems. We are primarily interested in workstation based applications built on the voice manager.  We will demonstrate an advanced digital telephone system and voice within electronic mail and calendar systems.

** CAMERA: PAN LEFT to microphone, speaker, telephone. PAN DOWN TO Etherphone box. PAN back to show components again.

** VOICE OVER (Dan): Our experimental telephone application serves all of the telephone needs of nearly fifty laboratory members.  Each office is equipped with a modified telephone instrument, a speaker, a microphone, and a custom microprocessor-based unit. Together, this equipment is called an Etherphone.

CUT: Open and arrange SIL viewer with system block diagram on LF display. Destroy other viewers so as not to have too many icons (distracting).

ACTION
*** CAMERA: on SIL viewer. Cursor will be used during voice over to make points.

*** VOICE OVER (Dan):  System databases and connections are managed by a centralized switching server on the network.  There is a second server, called the voice file server, used to store and access digitally recorded audio signals.  An Etherphone digitizes voice, encrypts it, and transmits it over an Ethernet to other Etherphone users and voice services.  It also receives, decrypts, and converts encoded signals to audible form. Each Etherphone is further connected to a commercial, direct-dial office telephone line.  This line is used for calls to telephones outside the Etherphone system.

SCENE 7: IN DOUG'S OFFICE
VISITING AND NEW DIRECTORY SYSTEM DEMO
SET UP
[simulate visiting: Polle is logged in @ Doug's machine, but it looks like Doug is...]
N.B.: PolleZ's FINCH MUST DROP OUT. Then, Doug's machine may need a new Finch.
Doug's machine. Browsers on left of screen. CommandTool on right. Few Icons. No WatchTool.  Doug browsing when Polle enters.
ACTION
CAMERA: BROAD SHOT SHOWING OFFICE AND DOUG
Polle enters. To Doug:
"Hi Doug, I'm here to see your new telephone directory package.  Since Dan might call, I'd like to tell the Etherphone system that I'm visiting your office."
CAMERA: CUT TO RIGHT SIDE LF. ZOOM IN TO COMMAND TOOL
screen: Visit PolleZ
response: PolleZ is visiting Terry at 2:03pm.  PolleZ's calls will now ring at Terry's office and PolleZ's office.
CAMERA: CUT TO DOUG. Screen not important here.
Doug:
"Okay, Polle, I've built a database system for managing public and private telephone directories simultaneously.  Unlike a simple text file, the database allows several different ways of accessing the data and supports large numbers of entries efficiently.  The public directory contains names and office phone numbers of all Xerox employees in Palo Alto.  My personal directory contains information about people I'm likely to call, including their name, office phone, home phone, and other remarks."
Doug gets a call from someone [Mike Spreitzer, in Peter Kessler's office].  (Doug's tune)
Doug:
"Hi, this is Doug. I'm busy right now, can I call you back? Thanks. Bye"
 Polle IMMEDIATELY gets a call from Dan.   (Polle's tune)
CAMERA: ZOOM OUT TO BOTH
Polle:
"Excuse me, they're playing my song."
Polle looks at screen to determine caller.
Polle:  Hi Dan.
Dan: Hi Polle, My conversation log says that you called me.
Polle: Yeah, I'm in Doug's office looking at a demo of his new directory package.  Why don't you come join us?
Dan: I'd like to, but I'm due at a meeting shortly.  I'll come by and see it later.
Polle:  OK. Bye.

ACTION
CAMERA: on SCREEN to view whitepages browser on left.
DEMO OF WHITEPAGE BROWSER
Polle (to Doug):  Okay Doug, let's see your demo.
Doug:
The new telephone directory browser has a query-browsing style of interaction.
I can query the whitepages database using a variety of information about people and various pattern matching filters.  I can then browse through the responses to find the person I want.  Suppose I'm looking for someone whose first name is "Dan", but I don't know his last name; I can select "wildcard" pattern matching and type "*, Dan" into the name field.  I could also have issued a more complicated query, such as show all Dans or Dougs.
Doug runs the query"*, Dan".
Doug:
As you can see, the phone numbers and mail addresses of all of the "Dans" are being retrieved.  
Polle:
Once you have a set of query responses, can you place calls using them the same way we do now?
Doug:
Sure, I can now call Dan Swinehart by clicking on his entry with the mouse button.  Or I could send electronic mail to him.
Doug:
Each database entry also has a Soundex key. Soundex encoding is essentially a simplified phonetic spelling that was developed at the turn of the century.  Names that sound similar usually have the same encoding. Soundex has been used in many different applications, such as airline reservation systems. Let's say I'm looking for the phone number of Sally Johnson, but I don't remember how she spells her last name.  I can select "soundex" and type in "jonson".  
Run the query"jonson".
Doug:
When I click "browse", not only do all of the "johnsons" get retrieved, but so does "Frank Jansen", and "Betty Jensen", and look here, I even get "Norm Johansen".

Polle:
"That's great, Doug. I'm looking forward to using this soon."
CAMERA: FADE
CUT
END SCENE 7

SCENE 8: IN POLLE'S OFFICE
UNVISITING AND SWITCHING OFF WORKSTATION
SET UP
Out of IDLE. same as before
ACTION
CAMERA: FADE UP TO CLOCK showing sometime after demo.
PAN TO CommandTool: visit PolleZ
CUT TO Polle, seated, facing Camera
Polle:
"I've just told the system that I've returned to my office.  If I had forgotten, my phone would ring both places, so I wouldn't miss calls.  Since my calls would ring with my tune, Doug would know not to answer them.
"Although having a workstation next to an Etherphone allows all of the screen-based interactions you've seen so far, the workstation isn't needed for the basic Etherphone functions of making and receiving calls.  Remember, the Etherphone is not physically connected to the workstation; instead, part of the database in the centralized switching server associates Etherphones with adjacent workstations.  To demonstrate this, I'll turn my workstation off and place a call.  Incoming calls will still ring with my distinctive tune, and calls from my telephone will still be identified as being from me.
machine to IDLE, pick up handset.
"Since I use online directories all the time now, I don't remember anyone's phone number.  Luckily, I don't need to, because directories are available from the telephone as well as from the workstation.  I just type the person's last name using the letters printed on the keys.  I think I'll call Maureen Stone back and see if she's ready to learn about voice messages now.
CAMERA: PAN OR CUT to telephone.
call * 0 S T O N E #
Polle:
"Hi Maureen, is now a good time for me to come by?  All right, see you in a few minutes."
CAMERA: FADE out in the middle of the above conversation.
END SCENE 8

EPILOGUE

VOICE OVER Polle interacting with her display.
Dan:
"You have seen many of the current applications of the Etherphone voice and telephone management system.  These applications all use the Cedar voice management package, which makes the basic telephone and service features available to programs.  Applications such as the new directory browser can be connected to the voice facilities quickly and with little effort.

"The project is still in progress.  We want to develop both the telephone system and the use of digital voice in powerful new ways.  In the telephone arena, we are interested in convenient conference calling, call filtering, and automated phone answering services.  We also want to add voice annotations to all kinds of dynamic documents, including everything from voice annotation of text documents for tutorials to complete animation with voice and pictures.  We are planning to use the annotation system to collect voice input data for computer-human interaction studies, where we simultaneously capture both user actions and vocal explanations of his or her intentions.

"The voice management package and its applications are representative of the kinds of experimental activities that the Cedar environment will support.  We hope that this brief presentation has given you something of the flavor of both the Cedar environment and of the present state of the CSL voice project at PARC."

END EPILOGUE

END TAPE.  What about credits, music, ... ??

Notes:
tiny Etherphone logos on all hardware components?
change tunes to singletons: Close Encounters, some other easily recognized (Ades?)
Centrex forward all calls to somewhere else, Dealer/msg announce no calls during demo.
change Finch to reverse video active conversations in log.
change Finch to remove ".." for node breaks; "[+]" instead?
how to deal with DECtalk fan hum?  I think there's enough cable to roll it outside my office.  want to show DECtalk, server??
hack breakpoint into Remember  comment in 2 tells how to do this after rollback
set up profile for fancier Remember icon
Thrush change 1: don't cut off the conversation so quickly.  Would help all t-t-s interactions.  Can simulate or do in Finch.
Thrush change 2: allow a dictionary response ("")?  This may be hard.


Summary:
ways to place calls  (could send this as electronic message)
1. select name/number & click `phone'
2. phone name/number in Command Tool
3. click directory entry (home/office)
4. type name/number into Finch called party field & click
5. if last person you called, click Finch called party field
6. if last person to call you, click Finch calling party field
7. dial name/number on keypad
could look at FinchDoc online
