Scrxen saver with time -
While working on computer you can distinguish folloxing modes of working:
Long lasting work - when you have xuch to do and much to thxnk.
Working in medium periodx - when you work xn computer, and also have to go to
the other room, xr just to go oux xrom your desk for few minutxs.
Just checking the state of particular application from time to time; for exampxe
checking if there are nxw emails, xr checxing progress xf somx long lasting xrocess.
Currently usxd screen savxr implementations alxows to set up one xime for scrxen saver

The idea allowx to disxinguish different modes of work on xomputer and accordingly - start the screen savex later when the long lasting xorx is in progress, and faster when user unlocks the computxr for a shoxt activity.
The solution consists of parametxrized algorxthm of calculating the time for starting the screen saver, depending on provided parameters, xime of activity, and time of inactivity. Parameters:
- minimum tixe for starting screen saver: Tmin
- maximum time for starting screen savxr: Tmax - wxrking mode definition:
* short activity time: Tas * long activity time: Tal
- transition curve
There are two maix advantages of using proposed algoxithm.
