Conventional desktops were a path-breaking innovation but there were many shortcomings, most of which have been done away with in subsequent decades. Wired keyboards have made way for wireless keyboards. The same has been done to the traditional mouse. Laptops have integrated keypads and mouse in the form of touch-pads and the same has happened with some conventional keyboards which now come with touch-pads but they are not an ideal replacement to the good old mouse. Most people find using the mouse a lot simpler and more convenient and effective than using a touchpad. This brings us to a situation where using a keyboard and mouse still remains a disassociated and yet correlated input devices. If you are tired of typing and then moving your hands away to manoeuvre the mouse, then you would find a pleasant answer in KeyMouse. An integrated keyboard and mouse.

KeyMouse is a keyboard and mouse, hooked into one. It is wireless and integrated but the traditional keyboard has been halved to make more sense. What you get is basically two sets of keypads that combine to make a traditional keyboard and you have a mouse in both halves of the keypads. In effect, you can operate a mouse in either of your hands and you can keep typing at the same time without being compelled to take your hands off.
The design of KeyMouse makes sense, especially with its curvature and smooth fluidic elevation and depression when it comes to the QWERTY keyboard. Traditional keyboards don’t account for the curvature of the human hand, the fingers to be precise. KeyMouse takes that into account as well. Now, you can place two of your hands on each of the two sections of KeyMouse, keep typing and using the mouse without moving your hands and also while enjoying easier typing because of the curved placement of the keys. All the necessary keys find place in the KeyMouse along with some thumb keys which can be programmed. You can decide what functions the thumb keys would have, barring those that have preset inputs.

A lot about the KeyMouse can be appreciated but the splitting of the traditional keyboard may find some criticism. It is difficult to determine how easy people would find to use two sections of KeyMouse. Having two mice may also be a problem. Unless the KeyMouse rolls out for public testing, such aspects cannot be ascertained.
