SmartNav

VoiceCode works great with a hands-free mouse such as the SmartNav. If you can use a regular mouse with no pain, there is no reason to go completely hands-free (unless you like the idea of standing up while working, or if you want to go hands-free for another reason)

The best place to purchase the SmartNav is: http://www.rjcooper.com/smartnav/index.html

The one you want is: HMEGX-11-USB EG for Mac OS X (SmartNav EG w/switch clicking) - $499

It comes with the software you need as well, which is a great value, since if you buy it somewhere else you do not get the software included and have to purchase it separately for $200.

Configuration

Here are the configuration settings that seem to work best with the SmartNav.

Boost Performance

If you experience any glitchy behavior in the mouse-movement, try running this command from the command-line to boost processor priority for the SmartNav:

`sudo renice -19 -p $(pgrep SmartNav)`

The Reflector

It's important to set up the reflector in a way that gives consistent and accurate mouse movement. Here is one solution that has worked well. It works specifically well because it uses a cylindrical reflector that does not change viewing size as you turn your head side to side, so the SmartNav has an easier time tracking its center of mass. It's also convenient because it is detachable.

Materials Needed

  • 1 rubber band
  • 1 drinking straw
  • scissors
  • reflective tape
  • 1 binder clip

Step 1: Cut the straw

Cut a small piece of the drinking straw, roughly the same width as the diameter of the straw

Step 2: Apply reflective material

Cut a strip of the reflective material, about the right size to wrap all the way around the small piece of the straw from step 1.

Step 3: Attach the reflector to the binder clip following the images below:

Thread the rubber band through the reflector
Put each loop of the rubber band on to the binder clip handles.
On each side, double wrap the rubber band around the handle by turning the rubber band then looping it over the handle again. If it's a larger rubber band you may need to do it twice.
Place the clip onto a hat or other pointing device.
Pull the binder clip handles back to tighten the reflector. Now the reflector is visibly the same size no matter what angle you turn your head.
