NAME

  optacon - An X program for the Optacon II

SYNOPSIS

  optacon [options]

OPTIONS

  -dev device
      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.

  -interval interval
      Specifying the -interval option instructs	the optacon utility to use
      the next argument	as the interval	for the	Optacon	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

  resource
      Specifies	the resource.

  value
      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
