NAME

       optacon - An X program for the Optacon II

SYNOPSIS

       optacon [options]

OPTIONS

       Specifying  the	-dev option instructs the optacon utility to use the next argument as the file for the Optacon II device.  By default, the
       device is /dev/tty00.  Specifying the -interval option instructs the optacon utility to use the next argument as the interval for the Opta-
       con  II	device.   The  interval  specifies  how  often (in milliseconds) the optacon utility will update the display of the Optacon II. By
       default, the interval is 10 milliseconds.

DESCRIPTION

       The Optacon II, a product of TeleSensory Corporation, is an optical-to-tactile conversion device meant to assist  the  blind  in  accessing
       visual information.  The optacon utility was made specifically to allow blind users to use an Optacon II to have more access to an X Window
       System display.	The optacon utility does so by mapping the pixels surrounding the on-screen pointer to the pins on the	Optacon  II.   All
       black pixels will cause the associated Optacon II pins to vibrate, and all other pixels will cause the associated Optacon II pins to remain
       still.

X DEFAULTS INFORMATION

       The format for a resource specification for the optacon utility is:

       *resource:value

       Specifies the resource.	Specifies the value that is to be assigned to the resource.

       For details about modifying resources, see X(1 X).

       Because each X Window System toolkit-based application can consist of a combination of widgets (for example,  push  buttons  and  a  scroll
       bar), you can form the name string for a new resource specification by adding widget class and name identifiers to the string.  For further
       information about adding class and name identifiers, see X(1 X).

       The following sample shows the optacon resources and their default values:

       *dev:	      /dev/tty00 *interval:	10
