Operating the OnScreenCommunicator via a switch
Switch instead of mouseMany patients are unable to use the normal computer mouse due to a disability.
However, if the patient can still move a toe, finger or his head minimally, he can use the OnScreenCommunicator via a switch.
The so-called "scan mode" in OnScreenCommunicator is activated for this purpose.
The Scan ModeIn scan mode, the OnScreenCommunicator scans all cells.
Once the scan is in the desired cell, the patient presses his button and the cell is clicked.
Depending on the type of cell, either the stored sentence is spoken by the computer voice, or a letter is written so that the patient can formulate a longer sentence that the computer voice then pronounces.
Different scan typesThere are different types of scanning available that are perfectly tailored to the needs of the patient.
With "Automatic scanning" the scan jumps automatically from row to row.
If the scan is in the row that the patient wants to select, he presses the button.
The scan now automatically jumps from column to column.
If the patient now presses the switch again, the cell is clicked.
This way the patient can have the computer voice speak a stored sentence, or he selects a key to compose a longer sentence.
Hold to scan
When holding for scanning, the patient works with 2 switches.
As long as the patient holds down switch #1, the scan moves from row to row.
The time after which the scan jumps on is of course freely adjustable.
Once the scan has arrived in the desired row, the patient releases the switch.
If he presses button #1 again, the scan moves in the selected row and jumps from column to column.
As soon as the scan has arrived in the cell that the patient wants to select, he presses button #2.
The patient works with 2 switches during "step-by-step scanning".
Each time button #1 is pressed, the scan moves one row forward.
When the patient presses button #2, the scan locks into the current row.
If the patient now presses button #1, the scan jumps from column to column.
By pressing button #2 the patient selects the currently displayed cell.
In addition, cells can be combined into so-called "scan groups". The scan then jumps from scan group to scan group instead of from row to row.
Experienced users can achieve great scanning speeds using scan groups because they can select the desired cell through the scan groups at lightning speed.
Adaption to the patient's needsA large number of options are available to perfectly adapt scanning to the capabilities and speed of the patient.
Up to 4 switches can be used to perform additional functions.
