Groupware
Software designed to support group working, not just to facilitate communication
CSCW (Computer-Supported Cooperative Work) - field of study which examines the design, adoption, and use of groupware.
not restricted to issues of "cooperation" or "work" but also examines competition, socialising, and play.

Advantages of Groupware
Groupware offers significant advantages over single-user systems.
to facilitate communication: make it faster, clearer, more persuasive
to enable communication where it wouldn't otherwise be possible
to enable telecommuting to cut down on travel costs
![Page 4: Groupware Howell Istance. SOFT3057 - Interactive Systems Groupware n Software designed to support group working, not just to facilitate communication](https://reader035.vdocuments.mx/reader035/viewer/2022062320/56649d615503460f94a42481/html5/thumbnails/4.jpg)
SOFT3057 - Interactive Systems
More advantages of Groupware
to bring together multiple perspectives and expertise to form groups with common interests where it wouldn't be
possible to gather a sufficient number of people face-to-face
to save time and cost in coordinating group work to facilitate group problem-solving to enable new modes of communication, such as
anonymous interchanges or structured interactions

Can be classified by When and where the participants are working The function it performs for cooperative working

at the same time (synchronous) or not (asynchronous) 2) where the participants are working
in the same place (co-located) or not (remote)

Collaborative Virtual Environments
Graphical or text-based environments where several people, remotely located, collaborate on some common activity (work-based or for entertainment)
Important to create the illusion of ‘presence’ in the virtual world, to make a person they are ‘in’ the world with other people
Worlds can contain shared artefacts or tools to facilitate collaborative working

Design Issues

SOFT3057 - Interactive Systems
User studies
Important to understand work-related needs of users of any system
user group testing is often difficult than for single user systems
pre-established groups vary in interaction style, determined by how long someone has been in a group
groups are dynamic - roles change within groups testing within organisations difficult as introducing new
versions may cause disruption studies often need to be long-term
![Page 21: Groupware Howell Istance. SOFT3057 - Interactive Systems Groupware n Software designed to support group working, not just to facilitate communication](https://reader035.vdocuments.mx/reader035/viewer/2022062320/56649d615503460f94a42481/html5/thumbnails/21.jpg)
SOFT3057 - Interactive Systems
Adoption and Acceptance
Perceived benefit - if the effort for an individual to use the system is not perceived to justify the benefit gained
Interoperability - concerns about compatibility between systems available on the market may inhibit adoption of any one system
![Page 22: Groupware Howell Istance. SOFT3057 - Interactive Systems Groupware n Software designed to support group working, not just to facilitate communication](https://reader035.vdocuments.mx/reader035/viewer/2022062320/56649d615503460f94a42481/html5/thumbnails/22.jpg)
SOFT3057 - Interactive Systems
Session Control
session - a group of people are in a conversation together at a given time,
session control - similar to a person standing at the door of a room checking IDs and deciding who gets to go in.
issues include finding out what rooms are available, determining who can enter and exit the room, and when and how.

SOFT3057 - Interactive Systems
Floor Control
access each person has to shared artifacts, or conversational functions
no control enables simultaneous access by anyone at anytime
alternative policies involve some form of ‘turn-taking’
![Page 24: Groupware Howell Istance. SOFT3057 - Interactive Systems Groupware n Software designed to support group working, not just to facilitate communication](https://reader035.vdocuments.mx/reader035/viewer/2022062320/56649d615503460f94a42481/html5/thumbnails/24.jpg)
SOFT3057 - Interactive Systems
Determining Conversation Structure
Technology mediated conversation - system determines protocol and structure for exchanges of messages
Socially-mediated conversation - how, when and if messages are responded to is left to the individual.
![Page 25: Groupware Howell Istance. SOFT3057 - Interactive Systems Groupware n Software designed to support group working, not just to facilitate communication](https://reader035.vdocuments.mx/reader035/viewer/2022062320/56649d615503460f94a42481/html5/thumbnails/25.jpg)
SOFT3057 - Interactive Systems
Customisation
Basic conflict between allowing one user to customise their view of information, and then sharing this view with someone else
Leads to possibility of confusion and errors customisation through
selection of information and emphasis of information presentation of information (e.g.colours)
![Page 26: Groupware Howell Istance. SOFT3057 - Interactive Systems Groupware n Software designed to support group working, not just to facilitate communication](https://reader035.vdocuments.mx/reader035/viewer/2022062320/56649d615503460f94a42481/html5/thumbnails/26.jpg)
SOFT3057 - Interactive Systems
Other groupware design issues
Avoiding Abuse ‘spamming ‘ with email is an example some form of ‘payment’ for the use of the system is a possible
means to reduce this Privacy
requires a balance between the need to share some information and keep some information private
a mechanism for information hiding necessary Awareness
issue of making others aware what an individual is currently doing ‘telepresence’ - feeling of presence of a remotely located person
![Page 27: Groupware Howell Istance. SOFT3057 - Interactive Systems Groupware n Software designed to support group working, not just to facilitate communication](https://reader035.vdocuments.mx/reader035/viewer/2022062320/56649d615503460f94a42481/html5/thumbnails/27.jpg)

Examples of awareness and privacy issues
Unobtrusive telepresence ‘In-your-face’ obtrusive telepresence
