6. Commands


A cell can perform one or more commands. The commands relate to the behavior of the cell, to what it does.


In general, there is no need to worry about commands. When you insert a message cell, for example, DomoPad'com is responsible for assigning the corresponding command ("Say the message of the cell"). The same happens when you insert a cell that jumps to another page or reads the message bar.


On the other hand, if you want a more precise control on how your board works or you want to do more sophisticated things (such as a cell to does more than one action), doing so is fairly simple.


To see the commands of a cell just edit it (double-click). Still with our board, let's edit the cell Eat. This cell has a single action that was added automatically when you created it: Say the cell text. Just that: when the cell is pressed, it says whatever text its has in it (in this case, "Eat").


But suppose we want the cell to say something slightly different. For example, "I want to eat." Just double-click the action, and change it.

Now the cell does not say exactly what is written on it, but "I want to eat" (try it). This is an example of how the cell appearance does not necessarily have to coincide with what it does. In the same dialog we can make the action show a different pictogram than that of the cell, or even assign it a sound from an audio file or the microphone for it to play, instead of using a synthesized voice as is done by default. If you use this option, the sound is saved in the DomoPad'com file.

But we can do more. Let's add another command by pressing the "+" icon. In the window that appears, select Jump to a page, then Food.

Now when the Eat cell is pressed two things happen: it says the message "I want to eat", and jumps to the page Food, allowing the user to choose what to say next. With a couple of changes you have created a much more intelligent board that can do the same with fewer steps.

7. Users and preferences


DomoPad'com Verbo allows different users to use the program on the same computer. Each user can set their own preferences, like the way in which messages are displayed or the access method to be used.




Click Users in the drop down menu to access the list of all users that have been configured in the program. You can add and delete users, rename them or even assign them a profile picture.

At all times there will be an active user in the program. This simply means that the preferences that the user has defined are being used, and that any changes made to those preferences will only affect that user. To change the active user just click Switch to this user.




The preferences dialog allows you to configure how each of the users see and use the program. It is very important to understand what each of the parameters that you can modify means to ensure that the program meets the needs, liking and way of working of each user.



The communication mode refers to how messages are displayed in the message bar :


     Symbols and text. Each message is a combination of image (pictogram) and text.


     Symbols only. Only the image is displayed, even if the cell has text.


     Text only. Only text is displayed, even the cell has image.


     Direct. The message bar is hidden, and every time a cell is pressed, it is read directly. Read, Delete and Clear cells stop working. This transforms the board into a more classic communication board.


In this section you can also configure the artificial voice with which the messages will be read.



This section allows you to configure what access system will be used to control the program. DomoPad'com Verbo supoorts a broad range of devices and types of access to suit absolutely any user, regardless of their level and type of mobility, cognitive level or visual acuity.


Devices supported by DomoPad are :


     Switches, via USB adapters as enCore.
     Conventional or adapted mice, head mice like enPathia, trackballs.
     Joysticks, gamepads or game controllers.
     Eye-tracking systems EyeTech TM5mini.


Depending on the selected device, DomoPad'com can be used in the following ways:


     Direct selection. The cell to be activated is selected directly. It is the access mode if a conventional mouse, a head mouse, eye-tracking system or a touchscreen is used. Just select the desired cell, and "click". Within this method, two variants can be used :


     – Activate the cells by clicking. The usual way.
     – Activate the cells by time. Instead of manually activating the cell, just dwell on it for a while. It is an interesting option if the user has mobility problems as it reduces the different types of movements that are necessary.


You can also enable the option to exit playback mode by dragging down the board instead of pressing F5 or Esc. It is a very interesting option if the program is being used in a device without keyboard, as a tablet.

     Scanning. The most common way if switches or keyboards are used. In the following section, Scanning, We will see the settings for this mode.


     Navigation. A cell is selected by moving up, down, left and right, and then it is activated. This mode can be used with switches or keyboard if the user is able to activate 5 different buttons, but the most common way is by joystick



Scanning is one of the most popular forms of access, and in this section you can configure how it will work.


     With Cell by cell, the cells of the page are highlighted one by one until the desired is activated. In the Rows-columns mode, a row is first selected and then a cell within it. The Columns-rows mode works in reverse. These last two modes allow a generally faster selection of a particular cell.


     Direction. You can choose the left-right and up-down direction of scanning, for example to match the user's reading direction.


     Scanning mode.


          – Manual. The user presses (the switch, the keyboard key, the joystick button, etc.) both to move to the next cell, row or column and to activate the desired cell. Note that this mode requires the user to be able to activate at least two different buttons: one to move to the next element, and another to activate.


          – Sequential.Cells, rows or columns are automatically selected at a rate that can be set. When the desired cell is highlighted, the user activates the button. This mode only requires access to one switch.
