NAME    [Toc]    [Back]

     imp - driver for IMP wireless presentation	mouse

SYNOPSIS    [Toc]    [Back]

     Streams module name: imp
     X name: imp

DESCRIPTION    [Toc]    [Back]

     IMPr is a wireless	hand-held multimedia computer control device for use
     when giving presentations.	 IMP consists of a compact, battery-powered
     remote infra-red transmitter and a	receiver that connects to the
     computer's	serial port.  With its unique force-sensitive Control Disc,
     IMP provides all the functions of a traditional mouse or trackball.

     IMP has a Manufacturer's Suggested	Retail Price of	$199.

     The driver	uses imp as the	X name of the device. (See input(7)).


     The imp driver provides the usual two valuators for x and y and it	has
     five buttons.  See	btnmap below for information on	the mapping of the
     device buttons to X buttons.

     The imp driver supports the following controls and	matching queries:

     bias <bias	value>
	  Bias is used to damp the motion indicated by the disk	on the imp.
	  The bias value is subtracted from the	incoming motion	delta.	Any
	  resulting deltas less	than 1 are set to 1.  This provides an annulus
	  of fixed speed around	the center of the Control Disc,	with smooth
	  acceleration as the user presses further out.	 Bias is applied
	  before scaling.  Bias	should be in a range from about	15 to 75.  The
	  default value	is 40.	The minimum value is 0 and the maximum value
	  is 75.  For example:

	  bias "30"
	       sets the	bias to	30.

     btnmap <button order>
	  The btnmap control permits the mapping of the	physical buttons to X
	  pointer button numbers to be changed.	 <button order>	is a comma
	  separated list of button mnemonics in	the desired order.  The
	  default order	is "cn,lf,lr,rf,rr". This is convenient	for righthanded
 operation.  It	maps the center	button,	cn, to X button	0, the
	  left front button, lf, to X button 1 etc.  The mnemonic names	are:

	       cn - center
	       lf - left front
	       rf - right front
	       lr - left rear
	       rr - right rear

	  For example:

	  btnmap "cn,rf,rr,lf,lr"
	       sets up a convenient mapping for	left handed operation.

     scale[xXyY] <scale	factor>
	  Control scaling on an	axis by	axis basis.  To	use this, first	set
	  scalewhich none in the X server (See input(7)) so the	X server
	  doesn't clobber your values.	For example:

	  scalex "1/5"
	       scales core pointer x events by one fifth.

	  scaley "5"
	       scales core pointer y events by 5.  The default value for both
	       x & y is	eight-tenths.

     The imp driver has	an additional query for	which there is no
     corresponding control.

	  This query returns either ok or low depending	on the state of	the
	  battery. The only way	to change this state is	to change the battery.
