Method and device and system with dual mouse support

A computer-implemented method for supporting two pointer devices in a computer device to which a first pointer device and a second pointer device are connected, and which runs an operating system with a graphical user interface, the operating system providing a native mouse cursor,

• the method comprising the steps of:
• b) allowing or configuring the operating system with the graphical user interface to provide said native mouse cursor as a visible object;
• d) providing a message handler for processing raw input messages, and configuring the operating system to transmit raw input messages originating from the first and the second second pointer device to this message handler;
• e) maintaining and/or modifying a first position in accordance with movements of the first pointer device, and adjusting a second position in accordance with movements of the second pointer device;
• f) adjusting a position of the native mouse cursor in accordance with movements of the first or the second pointer device, whichever was moved or operated most recently;
• g) detecting whether the raw input messages form or comprise a movement sequence according to a predetermined format, and upon detection of such a movement sequence:
• determining which pointer device caused this movement sequence;
• and
• moving the native mouse cursor to the maintained or adjusted position associated with the pointer device which caused the movement sequence;
• and
• sending at least one command selected from the group consisting of a button-pressed command, a button-released command, a scroll-up command and a scroll-down command to the operating system in accordance with the detected movement sequence.
