Access Devices - Part 1

Over the next four editions we will investigate which Input Devices (Computer Access Devices) are available in South Africa.

Natural Point Headmouse

Head tracking devices, like the Smart-Nav, have been on the market for years, so while this is not a revolutionary new type of device, the price is. The industry standard price for head tracking devices is $1000, which does not include the software necessary for complete computer control.

What do I wear?

Smart-Nav uses an infra-red (IR) camera to track your head movements. You reflect IR light back to the Smart-Nav, which sends instructions to your computer to move your mouse cursor. Put a paper thin tiny reflective dot on the part of your body you'd like to control the cursor with. Placing the dot on a hat, band or glasses are the current favourites.

Where do I put the Smart-Nav?

The Smart-Nav usually sits on top of your monitor, facing you. But you can clip it to laptops or place it behind you. It can be placed anywhere as long as it can see whichever reflective accessory you've chosen to wear.

How much do I move?

Less than an inch of head movement is more than enough to move the cursor across your entire screen. This is also adjustable in our software's "speed" settings. Smart-Nav has a 30 degree Field Of View (FOV), and usually sits about two feet away from your head. Thus you have at least a foot and a half of free "head space" in which to move that simple inch.

How do I click?

You can click with (redefinable) hotkeys on your keyboard, or you can plug a switch into the Smart-Nav device. Simple Click Switches eg buddy button, which can be joined, via our Y-Breakout Cable, to fully simulate a mouse.

There are three levels of user interactivity:

  • Complete Computer Control – Smart-Nav3 AT

The Smart-Nav3 AT package is your complete computer control solution, featuring a total Hands Free Mouse alternative for people with ALS, spinal cord injuries such as quadriplegia, muscular dystrophy, and other special needs. Comes with everything you need to control your computer using only your head motion.

This package is the ideal solution for Assistive Technology applications as it provides everything needed to have complete control of your computer without the need for hands.

Dwell Clicking

You can left click, double click, drag, right click, and more - with the "dwell click bar" software application. This software is great for individuals for have no hand function at all.

Natural Motion

Smart-Nav was designed to complement the natural head motion you already perform when looking around. Moving your head less than a quarter inch easily manoeuvres the cursor across your entire screen

Virtual Keyboard

You can type on your computer screen with Smart-Nav's virtual keyboard program.

Switch input

You can plug any switch directly into the side of the Smart-Nav. With the Y Breakout Cable you can plug in separate switches for left and right clicking.

Ergonomic Smart-Nav EG

The Smart-Nav EG package ends wrist strain, by eliminating the need for a mouse. With the built in switch input it's the best solution available for Carpel Tunnel Syndrome, Tendonitis, Repetitive Strain Injury, and other wrist strain related problems. The Smart-Nav EG is also for those individuals who have limited function but do not need dwell clicking as above but perhaps need the switches to right or left click.

Smart-Nav Basic for Increased Productivity or game playing

The Smart-Nav Basic package streamlines your computer usage by allowing you to use your head to do everything you used to do with a mouse. Reaching back and forth for the mouse wastes time and strains your wrist, which can lead to repetitive strain injuries. Smart-Nav is more accurate than many desktop mice and allows you to increase productivity, and prevent strain, by keeping your hands on the keys You can even click and double click with hotkeys on the keyboard. Price: R1493 + vat
