a system which allows a user to implement pop - up menus and gestural marks when the input location is restricted , such as in a corner region of a display , is disclosed . in such a situation , the system translates its position from one location where space is limited to another location where space is essentially unlimited . in such restricted locations , the system provides a indicator or guide to direct the user to make the required movement of the input device to the unrestricted location . such a guide consists of a visible path on the display from the current restricted location to the new location . the path guides the user into making the appropriate adjustment after which the user can proceed to make the appropriate menu selection or gestural mark .
