Smartnav provides a revolutionary hands-free way to control your computer using subtle head movements. A small reflective dot, placed on your forehead, glasses, or nose, is tracked by an infrared camera mounted on your monitor. This head tracking data is then translated into cursor movement by the included SmartNav software. This innovative technology offers a practical solution for individuals with limited mobility.
How SmartNav Works: A Deep Dive into Head Tracking Technology
The SmartNav system consists of two primary components: the hardware and the software. The hardware includes the infrared camera and the reflective dot. The software interprets head movements and translates them into on-screen cursor actions. This allows users to navigate, click, and even type without the need for a traditional mouse or keyboard.
The system is remarkably precise, allowing for accurate cursor control even with minimal head movement. This sensitivity can be adjusted within the software to suit individual needs and preferences. Furthermore, SmartNav is compatible with both PC and Mac platforms, although separate software versions are required for each.
Clicking with SmartNav: Dwell Clicking and Switch Options
SmartNav offers two distinct clicking methods: dwell clicking and switch clicking. The AT model utilizes dwell clicking, allowing for completely hands-free operation. By simply holding the cursor still over an icon or button for a predetermined amount of time (adjustable from 0.2 to 2 seconds), users can perform left clicks, right clicks, double clicks, and drags. This functionality works seamlessly with virtual keyboards and other accessibility software. The AT model on Mac also supports voice clicking for various actions, however, it’s important to note that Voice Clicking and Dragon for Mac cannot be used concurrently.
Both the AT and EG models support switch clicking. Using the included Y-cable, users can connect one or two external switches for left and right clicking. Positioning these switches for easy access is crucial, and accessories like an articulating arm can be helpful for optimal placement.
Typing with SmartNav: Virtual Keyboard Solutions
While SmartNav eliminates the need for a mouse, typing can be accomplished through compatible virtual keyboards. For PC users, the highly customizable OnScreen keyboard offers features like word completion, various sizes, macros, and speech options. While OnScreen is not available for Mac, a compatible virtual keyboard program called KeyStrokes is recommended.
