Physiolab Software Guide 44
The following display screens reveal one entire picture or one square of a larger
picture per step in a sequential order. Vendors have developed specific games,
such as races, to go with these screens. Contact J&J for a game vendor list.
Games Sequential - reveals an entire image on each step.
6x1 is a 6-square grid especially suited for race games.
3x2 and 3x3 are displays in which pictures are revealed from left to right in rows.
EEG AVI Screen allows AVI files to be played one frame at a time. A sample AVI
file is provided with the software to allow vendors to view the software
functionality for the purpose of developing and marketing games.
Selecting Game Images
Each screen type is designed to be used with a specific group of game pictures.
All the pictures that are used for game feedback are in the GamePics folder.
The GamePics folder is already selected by default in applications that ship with
the J&J software. In the GamePics folder are sub-folders containing specific
types of pictures. You can select these subfolders by clicking the Game
Windows button . All of the subfolders with names, such as animals, travel,
etc. are scenic images designed to be used with screens that reveal images
randomly.
If you purchase games developed by other vendors for use with J&J applications
you will need to click the Game Windows button and select a game picture folder
provided by your vendor. The game picture folder you choose should have the
same name as the name of the Screen you select.
EEG Bar Displays, Peak Graphs, Peak History Graphs
Bar Displays show peak microvolt values of individual bands. All bar displays
assume that band 1 is reinforcement, band 2 is inhibit and band 3 is artifact
inhibit.
There are two types of bar displays: with threshold and without threshold.
Displays with THR in the name indicate that the threshold is visible on the bar.
The threshold indicator line reflects the value of the threshold setting on the band
associated with that bar. In THR displays, the bar changes color when it crosses
the threshold.
Peak Graphs are line graphs showing all of the bands in peak microvolts.
Peak History Graphs show live statistics of performance. They show overall
success rate for the current task (the steps or reinforcements per minute called
“Score Now”), the overall score for the previous task (“Score Last”), and the
peak microvolt averages for each band with markers to show task boundaries.
