HMT Software Overview

(This article covers HMT Release 10 software.)
 My Documents

You can open PDF files and image files using document viewer with hands-free control.

If you select a PDF or image file from My Documents or My Photos, it is opened using the Document Viewer app.

Open a file by using the “SELECT ITEM #” command or by saying the name of the document without the file extension.

Zooming and Panning

To zoom in say “ZOOM LEVEL 2” or any level from 1 to 5.  “ZOOM LEVEL 5” will zoom in furthest.  When a document is zoomed in at any level past level 1, you can move your head to view different areas of the document.

A small thumbnail will appear in the upper left part of the screen with a purple rectangle representing the current view.

If you want to lock the location of the document say “FREEZE WINDOW”.  You can then move your head while the view is frozen.

To return to panning say “CONTROL WINDOW”.

Even when frozen, the view can be zoomed in or out.

To return a zoomed in window to the exact center say “RESET WINDOW”.
