Cognitive Psychology and human computer interface background
Flatline management. no hierarchy
Strategic alliances, cooperation because corporates cannot afford high level research.

Global Village - Only continent no responses to draft of book was Africa. Wonder why?

MICE project
Since late 80s
Global conferencing.
Get people to beta test and see how they use seriously. Try to work with businesses but initially researchers. They did not meet regularly and keep up a dialogue.

Video Conferencing
How to keep the dialogue going? Also without having to add gizmos to the machine.

Production of audio, video, shared workspace tools in public domain.

Slide of project working. audio when person is conferencing fce lights up. Graphic tools for demoing location.

MICE Applications (European Commission funded)
Open access to guest lecturers.
Can dial into secondary conferences

School projects - Global Schools Project. International Science Research. Projects on water pollution. Presented CUSEeMe - could compare results. Motivation factor for children eg worked with anti-drugs campaign. People generally forget the global and then people remember timescale.

Surgery Demos - Middlesex Hospital. Distance learning - surgery in realtime!

Art Happenings - Stormy WAters, Glasgow. Fed images into the internet. It was possible to interview artists via the internet.
Welsh Eistedfodd and Club music - relayed in real time on the internet
Lighthouse Gallery, Docklands - REaltime pictures from Azores with images overlaid.

Remote Learning project - point of talk
Video
Language learning. Hi tech language not taught in traditional classes.
Exeter and UCL to develop unique kind of distance learning
2 years in development. Computer networking using SUPERJANET.
Using simple keyboard and info is all on screen.
Video board, camera and audioline. Have to be
Shared white board. EVeryone can write or draw simultaneously. One of the most successful parts of the project. Integrated window is important in relation to previous projects such as MICE. Problem of making people large enough to relate to - takes up bandwidth or need to buy large monitors.

Can only run on PCs. Need vast amounts of info - white board, presence of people, text base.
Standard of Windows is a problem. There are no principles for designing good use of windows.

Types of windows

Split Tiled Overlay
Scrollable etc
Ways of dealing with them. Mixing types etc

Only computer scientists know how to use these devices or to design them.
Ordinary users do not like to multitask. Tend to be unconfortable with this.

Why is it called a Window?
What you see on screen is only a part of the actual file loaded into computer. Few people know why it is called a window.

New Interaction Paradigms needed
Virtual desktop - what is used now. Series of squares which represent different functions
Xerox Park - Use concept of rooms eg design room, video conferencing these will start automatically.
Fish eye view where everything can be seen but only focus on certain bits
Negroponte - LCD's Huge walls of them
Screen as desktop
Susan scan bin
Large projectors at Xerox park

Tables with screens work in certain abstract. Turning

Bill Buxton- Stuck with desktop computer. should have wetware. Can wear somthing on your sleeve.

Stuart Taylor - Military wearing IT stuff. Nurses also wearing.

Bill Buxton - appliances can communicate with each other wiht infrared links. angela has similar problems to simon but thinking that there may be a generic. Vision that one can connect at any time with people - surveillance almost. Tracking badges eg in museums. Guide which detects where audience is.

Simon - By replacing the computer with other things, it is putting it in the hands of the manufacturers. Convincing people to buy yet another gizmo.

Generic is sound - susan. If interface is standard all sorts of things can be done.

Interface at industry level not properly tested. Industrial designers win over ergonomics every time. Usability is too scientific and directors unable to get to grips with it - industrial design wins out.

AB social class buy cheapest video recorders so they can operate

Jon - cost. Need objects that allow different tasks so that mouse is not generic. However, we want to integrate our machines or tools eg tv and computer.

Jonathan - people want to distinguish between work and leisure. TV rep leisure; computer work.
Angela - TV piped into banks or companies.
Carey - Satellite info based eg CNN Angela - custom made channels.

Fiona - conferencing could be less formalised - a background noise of conference could be a good way to go.

Discussion of economics. Microsoft cannot keep it up.

Psychological studies on videoconferencing. Loss of body language over transmission. Carey.

Students in Relate did not know their tutors before or during the lessons, but people grew up a profile of each other. Quality of audio allows distinction of the person.

Maybe there is no necessity for interface. Ultimately plug-ins.

Difficulty of control in hierarchical situations
