How do I Adjust the Settings in Tracker Mode on my ECO?
When selecting the Tracker as your Access Method, you can customize the settings to work best for you or the user:
Acceptance Time
This is the amount of time it takes from when you point to a key until the device beeps and accepts the selection.
Horizontal Adjustment and Vertical Adjustment
If you are having trouble reaching the right or left edges, increase the "Horizontal" adjustment number. If you had trouble reaching the top or bottom edges increase the "Vertical" adjustment number.
If just the slightest head movement to the left or right moved you off the edges of the screen, decrease the "Horizontal" number. If the slightest head movement up or down moved you off the top and bottom edges, decrease the "Vertical" number.
If you had trouble positioning the cursor in the corners of the screen, increase both the "Horizontal" and "Vertical" adjustment numbers.
If you make large head movements you may lose the cursor easily. Try decreasing the "Horizontal" and/or "Vertical" adjustment numbers. If you make small head movements, try increasing the "Horizontal" and "Vertical" adjustment numbers.
Auto Repeat
This lets you choose how fast a key will repeat when you hold it down.
Selection Type
Manual means you must activate a separate switch to make a selection.
Auto means your the device will automatically make your selection for you.
Predictive Selection
Predictive Selection works hand-in-hand with Icon Prediction. (Icon Prediction is in the FEEDBACK MENU and the default is ON.)
When you turn Predictive Selection On, your device highlights only those icons where messages are stored. These highlighted icons are the only keys on the keyboard that will produce a response.
Note: Icon Prediction will work whether Predictive Selection is On or not.
Pointer Color
This allows you to select or create a color for the headpointing pointer.
In the pull-down menu, select Colors. Select Pointer Color in the Mouse Pointer Color box. Select a color.
Pointer Size
This allows you to choose the size of the pointer.
Averaging
Averaging helps you to cut down on accidental key activations caused by involuntary head movements. The number you select tells your device how far you must move out of one key location before a second key is activated. This generally means that when you cross the centerline between one key and the next key, the first key will become un-highlighted and the second key will light up.
If you select an averaging number higher than "1" you are telling the headpointer signal to "lag behind" any head movements you make. The higher the number you choose, the further into the next key's area you must move before the second key will become highlighted
Highlight Keys
This tells your device to place a red border around the key that you point to. This may help to make the selected key easier to see.
Field of View
This option allows the Tracker to adjust to they way your device is positioned—whether mounted on a wheelchair, placed flat on a surface or propped up on its table-stand.
If the communication device is straight up and down, or nearly so on your mount or a table, select High. If it is lying flat, or nearly flat, on a surface or mounted so that it is nearly horizontal, select Low. For positions in between these extremes, select Medium.
