The first personal computer was presented by IBM company in August 12, 1981. From this date exactly
the modern PC‟s age has begun.
29 years passed since that time, and no doubt, today we use different PCs.
Modern computers have gone far away from their ancestors by external appearance, power and facilities,
but general principles of human-computer interaction still keep working.
Keyboard & Mouse
First of all, it concerns information input devices – “mouse” (1963) and keyboard.

A great deal of attempts were made to change PC interface for changing the principles of work with
computer in general
Light pen, stylus, touch screen – but all of them were destined for work of one man only.
One of technologies we are interested mostly in – touch screen – exists since the end of 1977 when
Elographics company in joint efforts with Siemens succeeded in creating bulging touch screen adjustable
upon kinescopes of that time.
In 1982 on the World Fair Elographics presented the TV-set equipped with touch screen.
Today this technology is widespread in payment terminals where touch screen is used as if a mouse.
Changes in interfaces and operating principles have difficulty keeping up with development of computer
facilities themselves and growth in diverse ways of information operating.
Now the multi-touch screen technology does exist. And the fact that it permits to recognize user multiple
touches opens new quality horizons in human-computer interaction.
And today there are multiple examples of Multi-touch technology effective adoption – “Surface” and
“iPhone” for example.
But there is no soft- and hardware on the market which would require real multi-touch interface providing
multiple simultaneous touches.

What‟s significant – touch screen and multi-touch screen interfaces tend to minimize learning curve, they
are much easier-to-use and more understandable compared to what we used to working with by means
of usual PC‟s and operating systems.
Nowadays‟ PC is a unique tool for any person – be it a manager, chief or area specialist.
But they are destined for individual work.
It‟s to be taken into consideration that people pass their working hours mostly in negotiations,
presentations, brain storms, work group meetings.
All that implies much communication and simultaneous work of large number of people.
However, PC‟s are hardly intended for they are used simultaneously by more than one user owing to the
very fact that they are destined for individual (personal) work.
How is collective or group work carried out? As variants – meetings, negotiations? Such communication is
usually held at table, with some printed papers and minutes of meeting to fix important things which are to
By that the operation itself – or “work” – disappears, and what‟s kept is discussion only. Because there is
no such tool obtaining facilities and power of a PC, but at the same time providing collective and
simultaneous work of large number of participants.

What solutions does the market offer for such challenges? For example, these two products – and…
much of information noise.
The thing is that you will not understand how much complicated it is until you see another interface. Just
remind a teapot – you don‟t need instructions to heat the water.
Till today there is no computer created yet, aiming to facilitate the simultaneous work and collective
interaction of a certain group of people.
The key problem – there is no computer for several people (!!!)
„What we offer is to elaborate multiuser computer destined for joint work of people group..
The multiuser computer has to be equipped with a exclusively easy-to-use interface, which would let any
user accomplishes all operations he used to doing during a usual meeting, in easy manner and without
setting too much wits to work on it.
