The details of the Stenosaurus are taking shape. Above is a recent iteration of the keyboard layout. All dimensions are in inches. The blocks outlined in green are the shapes of the key caps - the part of the key with which your fingers directly interact. The key caps sit on top of and are connected securely to key switches - the part of the key that depresses, registers a key press, and passes the key press on to the microprocessor that runs the whole show.
The layout pictured above is not the finalized design, but it’s getting closer. The major changes from the layout we started with are:
In order to reduce cost and complexity, we decided early on to use the same Cherry brand MX line of key switches found in many computer keyboards. This type of switch has a different look and feel and is typically less adjustable than the lever-style keys found on many stenographs.
The downside of using Cherry MX key switches is the difficulty in finding key caps of the right size and shape. Most key caps for the Cherry MX key switches are slanted, curved, tapered, and have a roughly square footprint. We did find one level, flat, and untapered key cap, but it only comes in one square shape.
The two options we considered were:
So, now that you’ve seen the layout, what do you think? Do the key spacings seem like they will be comfortable? How do they compare to other machines you’ve used? If you have a stenotype machine, we’d appreciate you posting the dimensions and layout of its keys. Now is the time to give feedback on the layout! Thanks in advance.
