DESCRIPTION

        UR-98 is an Xorg input driver for the Union Reality UR-F98 headtracker.
 
        The UR-98 driver functions as a pointer input device, and can  be  used
        either as an additional input device or as the X server’s core pointer.
        The driver provides support for the three axes, throttle and four  but‐
        tons  of  the controller. If mapped as the core pointer the headtracker
        provides headtracking to try and place the mouse cursor where you look.
        As  a secondary input device the unit can be used for gaming, for exam‐
        ple to provide the look up/down and the turn in quake, and with  the  Z
        axis bound to ack/forward to provide movement control.
 
        The  default mapping maps left-right movement to X, up-down movement to
        Y and near/far movement to the Z axis. The throttle is  mapped  as  the
        fourth axis by default but can also be mapped as button 5.
 
        For  use in "head only" mode the Z axis can be mapped as a button. This
        allows the user to select objects with  head/neck  movement  alone  but
        takes some practice to use well.
        Union  Reality  UR-98. While this is a joystick driver the behaviour is
        absolute so this driver is not useful for true joystick interfaces.
        Please refer to xorg.conf(5) for general configuration details and  for
        options  that  can  be  used with all input drivers.  This section only
        covers configuration details specific to this driver.
 
        The following driver options are supported
 
        Option "MinX" "integer"
               Set the left hand X value from the headgear, for calibration.
 
        Option "MaxX" "integer"
               Set the right hand X value from the headgear, for calibration.
 
        Option "MinY" "integer"
               Set the top Y value from the headgear, for calibration.
 
        Option "MaxY" "integer"
               Set the bottom Y value from the headgear, for calibration.
 
        Option "MinZ" "integer"
               Set the nearest Z value from the headgear, for calibration.
 
        Option "MaxZ" "integer"
               Set the furthest Z value from the headgear, for calibration.
 
        Option "MinT" "integer"
               Set the low throttle value from the headgear, for calibration.
 
        Option "MaxT" "integer"
               Set the high throttle value from the headgear, for  calibration.
 
        Option "Screen" "integer"
               The  screen to attach to the headgear when running with multiple
               screens.  The default is screen 0.
 
        Option "Device" "string"
               The joystick port that is attached to  the  headgear  interface.
               This  is  usually  /dev/input/js0.  The digital port is not sup‐
               ported due to lack of documentation.
 
        Option "DeviceName" "string"
               Set the X11 device name for the headgear. This defaults to HEAD.
 
        Option "PortraitMode" "string"
               Set  the display orientation. The default is "landscape" but you
               can rotate the screen clockwise  ("portrait")  or  anticlockwise
               ("portraitCCW").
 
        Option "SwapXY" "boolean"
               Swap the X and Y values on the display. The default is false.
 
        Option "Button5" "boolean"
               Map  the throttle as a button instead of axis 4. For some gaming
               applications this can be more useful. The default is to map  the
               throttle as axis 4.
 
        Option "HeadButton" "boolean"
               Map the Z axis as button 1. This defaults to false.
 
        Option "HeadThresh" "boolean"
               Set the distance that is held to be mouse down.
 
        Option "HeadLock" "boolean"
               Set the range of depth around the mouse down point where mouse x
               and y movement is locked out. Set to zero to disable.
 

BUGS

        The "HeadButton" option is currently not implemented.
 
        The hardware or kernel driver has some idiosyncracies. Notably on  ker‐
        nel  initialization  the interface occasionally gets into a state where
        the readings rapidly cycle left-right-left-right or top-bottom-top-bot‐
        tom.   In  those  cases  it seems to be necessary to unload the driver,
        unplug, replug and reload the joystick  drivers.  Once  it  initializes
        sanely it remains sane.
 
        If  the  device refuses to work check the gray/black cables are plugged
        into the right ports on the unit. Be careful about this as crossing the
        cables  can lead to the device failing with a nasty burning electronics
        smell. The author writes from direct experience.
 
        This driver is currently Linux specific.
        Xorg(1), xorg.conf(5), xorgconfig(1), Xserver(1), X(7).
