MOUSE POINTING DEVICE FOR ANY SURFACE Russian patent published in 2015 - IPC G06F3/354 G06K15/00 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to a mouse pointing device. A mouse pointing device for mirror, transparent and smooth monochromic surfaces comprises a housing and, inside the housing, a chip set and an optical unit for tracking movement of the mouse, connected to the chip set, where in/on the housing there is one or more colouring units having one or more colouring heads which, based on commands from the chip set, are capable of applying an additional image or quasi-image on the bearing surface on which the mouse is operating using a liquid or water, including gas-saturated bubbles, using dust, by heating the bearing surface and/or cooling the bearing surface and then transforming the obtained heat image into a colour image using a cholesteric liquid crystal, and also using ice crystals.

EFFECT: providing reliable operation of the device on mirror, transparent and smooth monochromic surfaces.
