Quick overview


The KeyMouse™ is a keyboard and a mouse.  It allows users to operate the mouse without moving their hands out of typing position.  No more moving your hand back and forth between the keyboard and mouse.  It's designed for efficiency, comfort, and ergonomics.

We've put a lot of effort into making sure the KeyMouse™ is easy to use.  The main QWERTY key area is curved in both directions to allow for easy access to the keys.
The KeyMouse™ is designed to improve efficiency for anyone that uses the computer.  Uses include gaming, programming, CAD drawing, order entry, stock trading, web browsing, document editing, graphics design, and much more.
It's great for use when kicking back in a recliner.

The KeyMouse™ also allows you to keep your hands and arms at a more natural angle than a standard keyboard.

Keyboard enthusiasts love the Cherry MX mechanical key switches.  So we're incorporating them in our next prototypes and in the final product.

Note: Fn Yellow is "Number Shift" and Fn Blue is "Arrow Shift".

KeyMouse™ Software

The KeyMouse™ also includes software with lots of cool features to enhance the user experience even further.  The software is fully customizable and can be set up with many different profiles to easily switch between saved key layouts. 

Number Shift:  Holding down the Number Shift key allows you to quickly enter numbers using some of the keys on the right KeyMouse™.  This eliminates the need to take your hand out of typing position to use the number pad.  Using Num Lock has this same functionality.  This is basically a temporary Num Lock.

Arrow Shift:  Holding down the Arrow Shift key allows you to quickly arrow around using some of the main keys on the right KeyMouse™.  This eliminates the need to take your hands out of typing position to use the arrow keys. 

Arrows with Mouse: A handy feature for document and code editing.  While you hold this key down, mouse motions will move the typing cursor instead of the mouse cursor.  Great for navigating around quickly.

There are also many programmable thumb keys.  These keys are pre-programmed with any useful functions, but can be re-programmed if you'd like.  Pre-programmed functions include:  multimedia keys (next track, previous track, play/pause, volume up, volume down), browser keys (next, back, new tab, close tab, switch tab), ok, cancel, maximize, minimize, close.

Product Development 

We've been working on the KeyMouse project for several years.  Here are a few pictures that show some of the progress along the way.

The first few sets were created as one unit that was operated with both hands.

Then we decided to split it into two devices - one for each hand.  A design expert drew up many different sketches with different concepts we could use.  

We made several clay models to get the basic shape that fit the hand nicely.  Next a 3D computer model was created.  We used a 3D printer to print many different models to adjust the fit and feel of the devices. 

Technical Specifications

  • High Speed Bluetooth 3.0 for wireless.  Additional USB interface also for lower latency and battery charging.  You will have the option to use either interface.  While USB is plugged in, battery charges.
  • High Resolution Laser Mouse Sensor under both the left and right KeyMouse (either side can be disabled with a switch on the bottom of the device).  Resolution up to 3,200 cpi.
  • Mechanical key switches (Cherry MX brown).  The prototypes shown have Cherry ML switches, but we are switching to Cherry MX switches for our next prototype based on user feedback.
  • Backlit keys (primarily to be used when plugged in to USB).
  • Diodes on every key (N-key rollover & Anti-Ghosting)
  • Li-Ion Rechargeable batteries built in (Model 18500: 3.6v 1400 mAh) - charged by USB.
    Edited: We removed AA batteries with 6 month battery life as an option since we now have USB to charge the battery.
  • QWERTY keyboard including all function keys.  We are planning to offer alternative key sets printed with DVORAK, international, or other common layouts based on user requests.  
  • Dimensions of one side of the prototype (left KeyMouse) are: 7.25" x 5.5" x 2.3" tall.  We are working on an updated prototype, so this may change slightly.  We want to keep it as compact as possible, but at the same time make it easy to type fluently.
  • Weight for 1 side is 9.7 ounces. The actual finished product weight will be slightly different. We definitely want to keep it as light as possible. (In comparison, a Microsoft Intellimouse is 5.2 ounces.)  I've been using the prototypes, and they are definitely easy to move. There are large teflon feet on the bottom to help it slide nicely.
  • Operating systems: Windows, Mac, and Linux.  Software has currently been developed for Windows.  Mac and Linux software & drivers will be built, but may trail the Windows software.  Basic keys and mouse feature on the device work with no drivers.  The drivers/software is necessary for special keys (such as arrow shift, number shift, arrow with mouse, etc,) and programming.  The device will be fully programmable using desktop software.  The keyboard portion works on iOS (not fully tested). Keyboard and mouse portion works with some Android devices.  Mobile devices and tablets is not officially supported, but basic functions seem to work fine paring by Bluetooth.


  • January 2015:  Collecting funds & feedback from Kickstarter backers
  • February 2015:  Finishing final prototypes
  • March 2015:  Begin creating molds for mass production
  • July 2015:  Pilot production run
  • September 2015:  Completion of first production run KeyMouses
*These are estimates, but we will make every possible effort to meet this timeline.  If at all possible, we'll get them into your hands sooner.
