Introduction

   The computer technology has been developing rapidly from the last four decade. From
the punch card in 1890 to the first electronic digital computer built by John Atanasoff in
1939 to the first “personal computer” Altair 8800 invented by Ed. Roberts, from the
Apple I single board computer designed in the 1970’s to the first IBM PC, and from the
traditional computer text-based communication to the multipoint Video Conferencing
over the Internet.

In this paper, we will take a closer look at Multipoint Video Conferencing over the
Internet. Then we would discuss in detail of the CUseeMe, a software which provides
powerful multipoint videoconferencing functionalities over the internet. CUseeMe is an
Internet conferencing service that claims to be the “most popular, full-featured software
for seeing, hearing, and sharing with multiple people at the same time.”1 CUseeMe
allows real-time audio and video communication by providing multipoint video instant
messaging over the Internet. At last, we will discuss how CUseeMe supports
collaboration over the internet.


Significance of the topic

Compare to the computer from the past four decades, the computability of today’s
computer has increased in an exponential rate. As the computing power of the computers
increased, computer users also demand the computer to be physically appealing, mobile,
convenience and easier for distance communication.

Multipoint Videoconferencing has a great impact on distance education and online
collaboration in school environment. CUseeMe is used for educational and personal
communications and has a variety of applications, including holding meetings, doing
collaborative work, and exchanging information.2 CUseeMe supports collaboration by
allowing real-time communication between people who are in different locations, placing
it in the same-time different-place quadrant of the time-place grid. According to my own
experiences, ( I am currently helping Kealing Jr. High school’s multipoint
videoconferencing Algebra II class ), videoconferencing will great enhance online
collaborative multimedia learning and teaching in K-12 education. Thus, introducing
CUseeMe is of great significance to those who wanted to know more about online
collaboration and distance education.


A Plus: Integrating with Tablet PC
CUseeMe can integrate with Tablet PC, which is an innovative hardware which include a
touchable screen. With a sensible screen, students and teachers can just point to any

    http://courses.cs.vt.edu/~cs5734/student_reports/CUseeMe.htm
picture or text displayed on the screen and connects videoconferencing over it. In
Kealing Jr. High school’s distance learning classroom, they integrated Tablet PC feature
with videoconferencing system.



Discuss the topic based upon research

What is CUseeMe?
CUseeMe is a low-cost product for Internet videoconferencing. It is a full-featured
software for seeing, hearing, and sharing with multiple people at the same time.
CUseeMe runs on personal computers and provides real-time audio, video and text
transmission capabilities to machines throughout the world. CUseeMe sends its video
over any TCP/IP computer network, but it is primarily used on the Internet. It allows up
to twelve people to communicate with one another; depending on the users’ equipment,
they can hear and see each other if they have microphones and cameras attached to their
computers.


History of CUseeMe
CUseeMe is a desktop video conferencing program developed at Cornell University. In
the summer of 1992, graduate student Tim Dorcey and Dick Cogger started real-time
online videoconferencing when they created CUseeMe, a video conferencing software
program.

In February 2000, White Pine Software changed its name to CUseeMe Networks. The
new name was chosen to align the company's branding with its vision and focus for the
future. The company solidified its focus on Internet communications solutions. CUseeMe
Networks identified three areas for its organization: CUseeMe Software, encompassing
its software products; CUseeMe Services, a new hosting business and the industry's first
voice and visual ASP; and CUseeMe World, a consumer portal and showcase site for the
company.3

There are two ways to use CUseeMe. Users can connect to multiple people, using a
reflector, or they can connect directly to another users’ computer.

Connecting to the World with a Reflector
With CUseeMe, users can communicate with people from all over the world. Users
connect to a CUseeMe meeting place, called a reflector; once connected, users can see
and chat with others who are connected to that reflector. With CUseeMe, users can make
new friends, expand their professional and social networks, find people with similar
interests, and watch entertaining cybercast events.

    http://www.kmworld.com/news/index.cfm?action=readnews
To have a videoconference with more than one person, a reflector must be used. A
reflector is a dedicated computer that broadcasts and receives video images from more
than one CUseeMe session. Usually, reflector software will run on a Unix computer, but
there are versions now available for Windows/NT and Windows/95. Users can set up
their own reflector, if they have a computer available, they can create a reflector by
downloading the reflector software from the Cornell University FTP site, the White Pine
Software Website, or other Internet sites. Once a reflector is set up, or the user has found
one that someone else has setup that can be used, everyone in the videoconference must
connect to that IP address in order to chat.

Connecting to Another PC
Users can connect directly to another person without having to connect to a reflector.
This is called “direct connecting “ or “DC'ing.” To DC someone, a user connects to the
computer of the person he wants to DC with, using that computer’s IP address instead of
using the reflector’s name or IP address. To talk directly to one other person, once both
users have connected to the Internet, each user must tell the other one their current IP
address; this is usually done with an email.4



Comparison of CUseeMe to Similar Programs

CUseeMe’s multiple videoconferencing control features are often compared to similar
software, such as NetMeeting and Groove. CUseeMe’s most common competitor is
NetMeeting, a Microsoft product that “delivers a complete Internet conferencing solution
for all Windows users with multi-point data conferencing, text chat, whiteboard, file
transfer as well as point-to-point audio and video.”5 CUseeMe also competes with
Groove, a “desktop collaboration software for sharing files and working with others on
documents, tasks, projects and decisions.”6

Many CUseeMe users compliment the use of CUseeMe with NetMeeting in order to
compensate for some of the features that CUseeMe is lacking, such as file transfer,
whiteboard and file sharing features. The combination of CUseeMe and NetMeeting
provides users with a more complete package for collaboration. Both CUseeMe and
Microsoft NetMeeting are designed to operate at low data rates over packet-switched
networks, which appeal to many home and small business users.7 Although CUseeMe
brags about working well with NetMeeting, no documentation was found on their support
page to assist in testing this claim.

Implementation Requirements
There are hardware requirements for successful implementation of CUseeMe. First, each
user must have a capable computer with a soundboard and a videoboard. In addition, a
microphone and video camera are needed to use CUseeMe’s audio and video features.
The computer must have a connection to the Internet; the bandwidth of this connection is
the limiting factor in the performance of CUseeMe. The specific hardware and software
requirements for CUseeMe Version 5.0 are as follows:12

Versions
CUseeMe comes in two versions. The CUseeMe Web version is free and can be
downloaded from the CUseeMe website. The complete version of the CUseeMe 5.0 is
available for $39 per user. A trial version of CUseeMe 5.0 is available from the
CUseeMe website13 and is valid for 15 days. The versions have similar capabilities and
basic features, although the CUseeMe Web lacks some of the features of the complete
version.14



Chat Rooms
CUseeMe chat rooms can be accessed from the Channels area. Users may also create
their own chat rooms. The list of available chat rooms displays a brief description of the
chat room, the number of users in the session, and the rating of the chat room. The
ratings were broken down into three categories:
        G – General Audience, free of strong language
        PG – Parents Strongly Cautioned, may contain strong language and might not
        be suitable for children
        MA – Mature Audience only, may contain some strong language.
The site did not state who determines the rating. Many of the chat rooms had no rating.

Built-in Chat Rooms
There are three built in chat rooms: CUseeMe Café, CUseeMe Cantina, and Family &
Friends. The CUseeMe Café sessions have chat sessions from various countries, with
names such as Café Europa and Café Americano.

Creating a Video Chat Room
A title and a short description are required when creating a new chat room. The new
video chat room gets listed on the selected channel page. When a video chat room is
created, the creator’s CUseeMe nickname also appears next to the name of the chat room.
Other CUseeMe World Members can click on the chat room to join it. The new video
chat room will continue to be listed on the channel page as long as there are people in the
chat room. If people are no longer interested in the topic and everyone leaves the room,
the video chat room closes and will no longer be displayed in the list. Currently, chat
rooms cannot be password protected to prevent unwanted participants. Unwanted
participants may be removed only after they have joined a chat room.

     These features are listed in the section CUseeMe Web: Unavailable Features.

There is an option to report any issues or problems experienced in the chat room. During
a chat session, users may turn their microphone and speakers on or off. They can also
view the personal profile of anyone in the video chat room.




                           Figure 3 - Example of a Chat Room


Chat with Video
A list of active participants on the right column of the screen lets users know who is in
the chat room and if they are able to send video. To select another member’s video, the
user clicks on their window. A small picture, roughly the size of a passport photo,
appears on the screen. CUseeMe is designed to support up to twelve video connections at
one time, all of them viewable on a desktop computer screen. However, on a standard
computer screen, the visual quality of the images in the small viewing areas makes
communication difficult. In this case, the images are more for awareness of who is
talking rather than supporting the communication with nonverbal cues such as eye
contact and body language.15 There are always twelve video windows; if there are fewer
than twelve participants, the screen displays blank windows, which take up screen space.

Chat with Audio
The audio can experience network problems even if the video looks good. Audio
performance can be unpredictable. The computer in Calgary had excellent audio
reception, but the computer in Houston experienced audio lags of several seconds and
occasionally completely cut out. Because this is a common problem, Internet etiquette on
most CUseeMe reflectors suggests that users chat by typing. This is because not all users
have a fast connection to the Internet, and not all reflectors are high-speed computers.
Consequently, sending both audio and video through a reflector can slow down the
reflector and those connected to it. The preferred method for most users is to use text
chat, because it is the most reliable method and does not impede the reflector.16

Users
People usually have CUseeMe names that may or may not be their real names. These
names are often descriptive, and show the personality that the user wishes to convey.
Additionally, there are several types of users. People who have cameras are called
senders. People who do not have cameras, or are using video configurations that are not
accepted by the reflector, are called lurkers. Hidden users send video but cannot be seen
by all participants in a videoconference.


Group Videochat
Group videoconferencing, also known as videochat, by definition involves multiple users.
CUseeMe 5.0 allows users to see up to twelve video windows simultaneously. The
videoconference window is customizable, letting users set up the interface with an array
of options.

                     Figure 4 – Example of a Group Videochat screen


Channels
Chat rooms, described previously, are accessed through the Channels option.

Contacts
The Contacts listing provides presence protocol and connections management. Using
MSN, users can conference with friends in their MSN Messenger contact list. When a
person is online, their nickname is displayed in the contacts list of their friends’
Conferencing Companion.

Conferencing Companion
The Conferencing Companion feature allows connections to group videoconferencing
and buddies, as well as easy storage of favorite places and people to chat with. The
Conferencing Companion provides shortcuts, simplifying CUseeMe for users.

Favorites
The Favorites option allows users to create links to the sites they want to access, making
it easier for users to reconnect to their favorite sites and people because it is easier to
access a site or person through Favorites than it is to remember the correct IP address.
Users must have the IP address of the reflector they are trying to create a session with.
Users can create as many favorites as they want. This Favorites feature enhances privacy
because users directly access the computer they want to establish a session with, without
having to use the CUseeMe reflectors.
Preferences
With Preferences, users can change their configuration setting for things such as audio,
video, and personal information. Users can also configure their Firewall/NAT,
Gatekeeper, Call Notification and Access Control in order to optimize videoconferencing
based on their network environment.




                             Figure 5 - The Preferences Screen


Firewall/NAT
Firewall/NAT is a handy feature because most DSL and cable modem connections do
Network Address Translation (NAT). Consequently, users’ local IP address is not the
same as their external IP address. The “Test If I am behind a NAT” feature identifies the
users’ IP address. This IP address can then be given to friends to create a CUseeMe
session.

Gatekeeper
Gatekeeper assists others in locating a specific user with an alias such as an email address
or phone number.

Call Notification
Users define how they want the system to notify them of incoming calls. CUseeMe can
be set up to notify users of any incoming calls or to automatically accept incoming calls.

Access Control
Access Control allows users to select other users and sites that they grant or can gain
access to. It limits calls that can be made and received. Users can set it to notify them of
incoming calls or to automatically access their system. Call control allows users to
control outgoing and incoming calls according to an access list. There are three settings
to access calls: never, always, or to only accept calls from people on the access list. The
access list contains the URL or IP address of the acceptable computer.
.

Audio Settings and Video Attribute Selection
Selection of audio and video settings occur automatically at set-up, however, CUseeMe
5.0 allows users to customize these settings to meet their specific needs and preferences.

Video Instant Messaging
Video Instant Messaging allows two or more people to exchange only video-based
messages over the Internet synchronously. It is fast and it does not require complex
hardware or software installation.

Instant Messenger
Instant Messenger differs from the Video Instant Messenger in that it allows two or more
people to exchange both video and text-based messages synchronously over the Internet.
It is similar to videochat, but the audio is replaced by text messaging. In the CUseeMe
Instant Messaging tool, an Instant Messaging Contacts list appears. When a user clicks
on a buddy’s nickname, the system initiates a point-to-point videoconference with them.
CUseeMe’s Instant Messenger has the benefits and features of text-based instant
messaging, with the additional feature of video.


CUseeMe Web
The web-based version of CUseeMe, CUseeMe Web, has slightly different options from
the standard version. It is easy to install; installation took approximately 10 minutes.




                         Figure 6 - Main screen of CUseeMe Web
The following options are available in CUseeMe Web:

Take The Tour
The tour guides users through the features of CUseeMe Web. The tutorial appears
cluttered because there are a number of windows within the tutorial and it can be
overwhelming for the first time user. However, users can jump ahead by clicking on the
categories instead of using the built-in tutorial.

My Profile
The My Profile feature allows users to customize their personal profile. They can choose
whether or not to share this information with other members. This is similar to
Preferences in CUseeMe version 5.0, but the complete version has more settings to adjust.

Channels
The Channels feature has access to the same channels as the complete version. However,
in order to access the Internet Video chat directory, users must have the full version of
CUseeMe 5.0, CUseeMe Pro or CUseeMe for Macintosh software.

Unavailable Features
The following features are not available in the CUseeMe Web version17

      1. Point-to-Point chat (privately)
      2. Instant Messaging with Presence Protocol via Microsoft MSN Messenger service
      3. Favorites for marking video chat sites and static IP addresses
      4. Customizable window with 1 - 12 windows
      5. Freeze window pane
      6. Vary size of window
      7. Block chat of other users
      8. Show who is talking/sending audio
      9. Set video send and receive rates to control quality
      10. Set audio in and out and squelch levels
      11. Point-to-Point compatibility with NetMeeting (H.323), Vcon Vigo and Polycom
          ViaVideo

Problems
CUseeMe is not without problems. While reading comments on the CUseeMe forum, it
seems that the CUseeMe server goes down frequently, frustrating users and resulting in a
diminishing customer base.

CUseeMe also seems to have difficulty with the demand for its basic functions.
Linktionary states that CUseeMe’s strongest feature, the ability to join multiparty
conferences within CUseeMe reflectors, probably will not appeal to business users18.
While similar software problems appear to be refining their product and overcoming
problems, CUseeMe has not made significant changes to their product in the past two
years. In fact, several users have complained that CUseeMe 5.0 is a step back from
version 4.0.19 This regression, combined with the continuing network problems, is
causing CUseeMe to rapidly lose market share as users switch to competitors’ programs.


New Features of CUseeMe Version 6.0
CUseeMe Networks has stated that the next version of CUseeMe will have the following
additions:20
   • Full Screen Video with Picture in Picture

      •   User-Created Private 1 on 1 Rooms

      •   User-Created Private Group Rooms

      •   Scan-a-Room feature, which lets a user see up to 22 windows at one; currently

          users can only view 12 windows

      •   Instant Messaging with CUpals

      •   Block users with CUcreeps.

CUseeMe Networks has not announced when version 6.0- will be released.


How CUseeMe support collaboration
Various features of CUseeMe support both Collaboration1 and Collaboration2.
Collaboration1 (C1) is the communication and coordination of activities. Collaboration2
(C2) is a process of value creation through cooperative work directed to solving a
problem, creating, or discovering something within a set of constraints.

Each feature of CUseeMe has its unique way of supporting collaboration.




   Instant Messenger supports C1 and
   C2 because it supports information
 sharing and cooperative work directed
          to solving a problem.

Instant Messenger
Instant Messenger supports C1 because it is a tool for group communication for
information sharing and it allows instant information exchange. Instant Messenger also
supports C2 because its text information sharing system supports cooperative work
directed to solving a problem. CUseeMe supports value creation among group members
through their interaction and collaboration. However, the Instant Messenger does not
have document-sharing features, nor does it have the collaboration document function21
common to other software. Thus, CUseeMe Instant Messenger does not have a strong
support for C2. When group members cannot work on a commonly shared file, it creates
barriers for group collaboration in problem solving and value creating.

Group Videochat
The Group Videochat feature supports C1 and C2. It supports group communication, and
can also be used for a group to build on each other’s opinions in a problem solving
approach. This falls into the definition of C2.




21
  The collaboration document function allows multiple group members to write in a document at
one time. The document is also available to all group members.
Application of CUseeMe in Education:

Schools often use CUseeMe for distance learning. The Washburn University School of
Law in Topeka, Kansas, was able to use CUseeMe to explore ways to transmit committee
meetings for their regional library consortium, broadcast their guest lecture series,
conduct job interviews, perform technical support demonstrations, and hold moot court
and mock trial competitions. They plan to videocast some of the activities of their annual
alumni reunion, and have explored the possibility of setting up a videoconference for
prospective students.

CUseeMe technology has been used for other interesting applications. One school set up
a camera in their computer lab so that students can see how many people are using the lab
and decide whether to come in or not. CUseeMe is also used to carry video feeds of
television programs to classrooms that have computers but not televisions. Classroom
videoconferencing is also gaining popularity as this technology becomes more prevalent.
22
   In cases such as this, CUseeMe demonstrates its support of C2 as it is used to solve
problems through interaction and collaboration.

Schools use CUseeMe to communicate with other schools and organizations. Video-
conferencing offers Museum in the Classroom schools an opportunity to further interact
with museum and zoo personnel as well as with each other.23 Many schools are using
CUseeMe to connect to the Global SchoolNet Reflector for conferences with other
schools worldwide. This provides online opportunities for teachers to collaborate,
communicate, and celebrate shared learning experiences. The Percy Julian School, in the
United States, has been communicating weekly for the past five years with a school in
Dublin, Ireland. Each link is for about an hour. Contact is made over the Internet using
their permanent IP address. This is a before- and after-school activity because the time
difference means that they cannot connect during regular school hours. The children of
both schools know each other so well that they can chat to each other like old friends.24
NASA offers Classroom Collaborations which involve interaction between classrooms in
design and/or decision making processes, usually overseen by a NASA expert.
Additionally, students experience the excitement and inspiration accrued from interacting
live with someone who works for NASA.25 CUseeMe makes this communication easier
and more affordable.


Summary

CUseeMe is valuable communication software that is both easy to use and affordable. It
is simple enough to be used for personal communication, and is powerful enough for
business collaboration. It is a popular choice for real-time audio and video

communication through multipoint video instant messaging over the Internet. Besides
being the original real-time video communication tool, CUseeMe is still an excellent
choice for communication between remotely located users.

While CUseeMe is a decent product, the lack of features, such as the collaboration
document function, prevent CUseeMe from being a serious contender for pioneer
videoconferencing. Until features such as this are added, CUseeMe will be relegated to
personal and academic use.
