Tree View –This panel contains the directory listing of the “ELCL” folder
of the Host PC hard drive as well as any other drives attached to the Host PC
(e.g., a USB flash drive). The following two folders are essential to the operation
of the eye tracker: the “elcl\exe” folder, which contains the Host application
that runs the eye tracker as well as the configuration files, and the “elcl\data”
folder, which is where all of the EDF files created during the experiments are
stored. The “elcl\data” folder also stores the log files for the recording sessions
and screen grabs created by pressing ALT+F7 on the Host keyboard, which can
be used for troubleshooting purposes.
The Tree View panel allows users to navigate around different folders of the
Host PC. The currently-selected folder is highlighted in a blue background
color. The subfolders and files within the current folder are displayed on the
Folder View panel on the right. Navigating around the tree can be accomplished
either by using the mouse, or by using the following keys.
•
UP and DOWN arrows: move up or down along the tree.
•
LEFT ARROW: if the current selection is an open folder, it closes it;
otherwise it moves up the list to the parent folder.
•
RIGHT ARROW: if the current selection is a closed folder, it opens it;
otherwise, it moves down to the first child folder if there is one.
Clicking the right mouse button displays actions supported on the currently
selected folder (cut, copy, paste, delete, rename, download, eject) on a popup
menu. Not all operations are supported for all folders. Clicking on the download
button allows you to download all of the files and subfolders in the currently
selected folder to the local computer (usually in the “Downloads” folder of the
user account). Clicking on the Upload button allows you to upload files to the
currently-selected folder of the Host PC. Neither the download nor upload
operation is supported on the Host PC when the Web UI is running. If a USB
drive is connected to the Host PC, this drive can be ejected by choosing the
“Eject” option from the right-click popup menu.
The disk space of the current drive will be displayed if the mouse cursor is
placed on the uppermost parent folder of the tree.
The Tree View panel can be shown or hidden by clicking on the “Show/Hide
Tree View” button in the toolbar. The size of the Tree View/Folder View windows
can be adjusted by placing the mouse on top of the separation bar between the
two panels. Once the resizing cursor shows up, drag the separation bar to the
intended position.
