A visual scene display (VSD) is a photograph or picture with active areas or hotspots that a user can select to communicate. Blackstone (2004) defines a VSD as a picture, photograph or virtual environment that depicts and represents a situation, place or experience. Individual elements such as people, actions and objects appear within the visual scene.

For example, a photograph of someone’s desk may contain a photograph of their family, a computer, some keys, some stationery and some books. The objects on the desk could be pressed or clicked to produce their names, e.g. keyboard, screen, pens, computer. The photograph could be clicked on to move to an additional display with a family photo. People in the photo could then be clicked on to retrieve their names. Or a photo taken on a trip to the zoo could be used to talk about the trip, who went on it, what they did and what they saw. It may also be used to retrieve the names of animals or people in the photo.

A VSD can be a single photo or a group of photos. The picture below shows a visual scene display designed for the user to talk about a trip to Canberra. The main photo is used to set the topic and to talk about the trip. The buttons around the sides give further information about particular people or sights.

Research into VSDs and their use with young children with developmental disabilities, people with acquired communication difficulties (such as those who have had a stroke or head injury) and people with multiple disabilities is just beginning. So far, the indications are that VSDs may be an option to support social communication and retrieval of vocabulary for those who find more traditional communication grids difficult or challenging.

For more information about VSDs with young children you can go to the 2006 CSUN Conference session report:

For information about VSDs and people with aphasia you can go to the Powerpoints of the AACRERC session presented by Beukelman et al:

And keep an eye on the web as more information about VSDs is available each time we look.

To create your own VSDs in the DynaVox software you will need to have selected the photo or photos that you wish to use. In this example, we will use the following photograph of family dinner party at a hotel.

Setting up your digital photo as the background of a page

Prepare the picture:

1. Make sure the picture you want to use is no larger than 800×600 pixels. Use third-party graphics software to edit or size the picture accordingly.
2. Once the picture is the proper size, copy it to a USB storage device.

Copy the picture to the device:

1. Insert the USB storage device into the USB host port of your DV4/MT4 device.
2. Select the pull-down menu button from the title bar at the top of the page.
3. Select Setup.
4. Select Tools Menu.
5. Select File Browser.

Adding Active Areas to the picture

Now that you have your photo in the background, you need to add some active areas so that the page can be used to tell a story or to communicate with.

Active areas are like buttons though they have no borders or defining appearances. Selecting an active area will activate any behaviours that have been assigned to the area. Please follow these steps to add an active area to a page:

Please be sure that you are still in Page Editing before following these instructions.

1. Select the arrow to the right of the Message Window tool in the Tools palette.
   
2. Select the Active Area Tool.
   
   • Note: This tool resembles a starburst
   
   
3. Select an area on the screen where the active area will start. Hold the selection and drag out the boundary for the active area.
   
4. The Behavior Editor window will appear.
   
5. In the Behavior Editor menu, select the behavior that the active area will perform. For our purposes this will usually be Speak Text.
   
6. Select the Add button.
   
7. A keyboard will appear. Type in the text that you want the button to say. For our example we are going to type “This is my Mum. She loves a good bottle of wine.”

   Press OK when you have finished.

   Note: You may assign multiple behaviors to an active area. If you wish to add other behaviours to this active area then do so now.
   

8. Once all desired behaviors have been added, select OK to exit the Behavior Editor menu.
   
9. Select the pull-down menu button in the title bar.
   
10. Select Exit Page Editor.
    
11. Select Yes to save the changes.
    
12. Select the active area to test the behaviors.

Repeat steps 1 to 12 to add as many active areas as you require.
