how it works

Key layout

The photos on this web page show photos of an earlier prototype.

The combimouse is a patented split keyboard.

The left part is stationary and provides the function of the left hand side of a conventional QWERTY keyboard. The right part has a similar mass, centre of gravity and moment of innertia to a conventional mouse. It also has a similar grip.

The right part is a mobile combination keyboard and mouse that can be moved around on a support surface like a conventional mouse. The keys are arranged in the fashion of the right hand side of a conventional QWERTY keyboard.

By default the right part operates in keyboard mode. When the user grips the right part and so touches the side of the part in the area labeled above as 'Contact switch', the right part automatically changes to mouse mode.
When in this mode, movement of the right part
enables cursor movement on the screen and as described below the keys become mouse click buttons and take on the functions labeled in green text.

Moving between keyboard and mouse modes is effortless and intuitive. The transition time between the two modes is insignificant.

The combimouse has been configured to enable two different methods of operating the right part whilst in mouse mode. The hand positions for both are comfortable and intuitive.

Grip 1 has only two fingers on the mouse keys. The comma key doubles as the left click button whilst the L key doubles as the right click button.


Grip 2 has three fingers on the mouse keys. The left click button is the J key, the middle click button is the I key and the the right click button is the O key
