[MUSIC PLAYING]
At Xerox PARC, we've been investigating the marriage
of four different technologies, pen computers,
wireless networks, infrared sensors, and radio frequency
or RF sensors.
By weaving these together, we can enhance the user experience
and blur the boundary between physical and virtual
information.
For example, here's Anuj, a computer researcher working
in this enhanced environment.
Anuj has been asked to update a research paper.
He can't remember where the paper is stored on the network.
It's been on the back burner for a while.
However, Anuj can find an old printout of an earlier
version of the paper.
Anuj wraps the document on the computer.
The document is tagged with a link
to the latest virtual version on the network, which is then
loaded into Anuj's computer.
Anuj begins to work on the document
and comes across a reminder to insert a quotation
from a reference paper.
The bookmark marks the physical page
but is meaningful in the virtual setting too.
When Anuj wraps it on the pen computer,
the bookmark section is loaded.
Anuj can easily copy the paragraph into the article.
However noticing that it is written in French,
Anuj must first translate it to English.
To invoke the French to English translation service,
and news wrap's his French English dictionary
against the pen computer.
Everyday tools can keep their familiar meaning
in this augmented electronic world.
Anuj gets a phone call asking him
if he can come to a meeting that's starting in 15 minutes
Oh, yeah.
The meeting.
I'll be right there.
He checks the time and brings up his schedule for the day.
Like the dictionary, the watch has
been augmented with a natural electronic association.
Anuj then uses a bookmark to mark the current state
of the computer and of his paper and heads off to the meeting.
In the hallway, Anuj meets Chris.
Chris just got a copy of a new book which he enthusiastically
recommends to Anuj.
Anuj skims it and agrees that it would be great reading
for his next airplane trip.
Anuj wraps the book on the computer.
And it is automatically ordered through amazon.com.
We can see that in addition to linking content,
tags can invoke special services.
Individual items can have multiple tags,
each with their own purpose.
Chris asks Anuj about attending an upcoming talk.
The talk looks interesting but Anuj would
like to know more about it.
By wrapping on the title of the talk,
a detailed talk abstract is displayed on Anuj's computer.
Based on this, he decides this would be a good talk to attend.
By wrapping on the date of the poster,
the talk is entered automatically
into Anuj's calendar.
Rooms can have actions linked with them.
As Anuj enters the meeting room, he
uses a laser pointer to tell the IR beacon in the ceiling
that he has entered the room.
The computer brings up the agenda
for this particular meeting on Anuj's computer.
Hey.
Hey, Anuj.
Hey, guys.
What I miss?
[INAUDIBLE]
In the meeting, Anuj refers to a report
issued about a month ago.
A visiting colleague asks Anuj if he can email him a copy.
The colleague's business card has
been augmented to trigger the sending of email
to him, making this easy.
Leaving the meeting, Anuj decides
it would be nice to have a printout of the report
to read on the bus ride home.
Spying a nearby printer, Anuj gets the document printed out.
He doesn't need to know the printer name or the file name
for that matter.
Area and object tags can provide dynamically changing content
information such as stock price.
At Xerox PARC, we've linked a fountain
to the Xerox stock price.
The better the news, the greater the flow.
As Anuj walks by the fountain, and IR beacon senses
Anuj's computer's presence and automatically displays
an exact stock quote on the computer.
We hope this sequence has shown that by melding networks,
sensors, and portable computers, a new and powerful user
experience is possible.
The examples you've seen in this video demonstrate only a few
of the many possibilities.
