Abstract: The present invention provides an executable program loaded in the computer memory as a process and periodically automatically polling computer's communication ports to identify pointing devices coupled to the computer via the corresponding communication ports, managing a set of views of the file-mapping objects of the corresponding conventional cursor driver files mapped to the program process's virtual address space to support simultaneously a plurality of cursors independently controlled by the corresponding pointing devices.

Abstract: A method and system for increasing computer operators' productivity in connection with the application which does not support multiple relative-pointing devices, over manipulating simultaneously and independently of at least two pointers on the same display screen of the computer by means of hands, feet, fingers of at least one computer operator over manipulating of the corresponding relative-pointing devices such as mice, trackballs or the like, coupled to the computer and associated with the corresponding pointers, wherein signals from the relative-pointing devices are being processed by shared cursor driver.

Abstract: A viscous substance containing tube comprises more than one lid-covered outlets. These outlets can be implemented at each of two tube's end and can be implemented on the tube's surface, between two tube's ends. Each outlet is used to squeeze out of the tube the portions located in the vicinity of that outlet by applying a squeezing force on the surface in the vicinity of chosen outlet. The simplest embodiment of the tube comprises only two outlets—an outlet per each of tube's end.
