  Information display kiosks are useful in libraries, galleries and
  museums, educational institutions, municipal offices, visitor
  information booths, conferences, shopping malls, airports---in short
  any location where simple, easy access to information is desirable.
  Kiosks are normally set up with touchscreens or pointing devices such
  as trackballs, to allow people to select and view information that is
  attractively displayed and up to date.

  There are many ways to create kiosks, from expensive solutions based
  on proprietary software to HTML-based open-source solutions. Browser-
  based technologies are particularly attractive because they are
  inherently multimedia, offering text, graphics, sound and streaming
  media, and the content is highly portable.

  Linux provides a flexible and interesting platform for kiosk
  development. Linux is inexpensive to set up and it offers a wide range
  of options, from diskless display stations to self-contained,
  database-driven web servers. Due to the versatility of the underlying
  operating system, a well-designed Linux kiosk can be placed in a
  remote location and administered via a telephone or network link.

  This HOWTO explores one method of setting up Linux as a standalone
  information kiosk, using Netscape Navigator 4.X and FVWM2 on a Red Hat
  Linux 6.X system. It is based on a kiosk I set up for use in the
  _H_a_n_d_s_-_o_n _B_i_o_d_i_v_e_r_s_i_t_y _G_a_l_l_e_r_y in the Royal Ontario Museum (
  <http://www.rom.on.ca>), Toronto, Canada. The kiosk outlined in this
  HOWTO incorporates a trackball rather than a more expensive
  touchscreen. There are undoubtedly many other ways to create a Linux-
  based kiosk, but this one has worked reliably for us and it may
  provide a useful starting point for your own kiosk project.

  Our Linux kiosk derives heavily from the work done by the City of
  Charlotte, North Carolina, for their municipal website, _C_h_a_r_l_o_t_t_e_'_s
  _W_e_b (see  <http://www.charweb.org/webinfo/kiosk/>). The Charlotte's
  Web kiosk project, which employs a touchscreen monitor, was set up in
  1996 using an early version of Slackware Linux, Netscape Navigator
  2.X, and FVWM. The webmasters at Charlotte have created a very useable
  kiosk implementation and have shared their complete setup via their
  website. This HOWTO, to a certain degree, represents an update of
  their work, altering the details to work with Red Hat 6.X, Netscape
  Navigator 4.X, FVWM2, and a custom-made trackball.

  I worked with Debra Luneau (debral@rom.on.ca), the Royal Ontario
  Museum webmaster, to create the graphics overlays for Netscape. The
  examples we distribute at our ftp site are her work---and are the ones
  we use on the kiosk in the Biodiversity Gallery.

  The Ontario Biodiversity section of the ROM website was designed by
  Hopscotch Interactive (www.hopscotch.ca). The original application was
  converted from a flat-file database system to a MySQL-database driven
  system by Gord Howells (gordonh@rom.on.ca), the ROM's database
  designer and programmer. The non-kiosk version of this mini-site may
  be viewed at  <http://www.rom.on.ca/ontario/>.

  Setting up Linux for use as a web-based kiosk is similar to setting up
  Linux as a graphical workstaion, with a few extra considerations. If
  the machine is to be a standalone unit, it must boot straight into
  kiosk mode. Furthermore, the browser environment must be modified in
  to disable standard dialog screens and to eliminate parts of the
  browser that allow inappropriate interaction, such as the Location Bar
  in Netscape.

  Essentially a kiosk website is self-contained. Users navigate through
  the site via clicks with a pointing device. The pointing device can be
  a touchscreen, a trackball, or a mouse. Mice are difficult to secure
  in a public area.

  A Linux kiosk can be connected back to a home site via a direct
  network or PPP link, requesting pages from the home site, or it can be
  a self-contained website, running Apache and any corresponding CGI
  modules.

  33..11..  FFVVWWMM22

  FVWM2 (FVWM, version 2 -- www.fvwm.org) is a flexible, reliable, and
  lightweight X Window manager that provides excellent configurability
  for creating a kiosk environment. For kiosk use you must change some
  of its default settings. You need to modify the system.fvwm2rc file to
  remove things like virtual desktops, title bars, exit controls, etc,
  leaving a relatively minimalist FVWM environment. Because the kiosk is
  a standalone unit, modifying the system-wide settings does not present
  a problem.

  You can also take advantage of FVWM's settable object properties to
  use X Window bitmaps (xpm files) to mask the parts of Netscape
  Navigator you don't want users to access.

  The FVWM2 file you need to modify is /etc/X11/fvwm2/system.fvwm2rc.
  (If you use a different distribution than Red Hat, this file may be
  located elsewhere.) You may have to poke around in this file to find
  the sections listed below.


  33..11..11..  //eettcc//XX1111//ffvvwwmm22//ssyysstteemm..ffvvwwmm22rrcc

  In /etc/X11/fvwm2/system.fvwm2rc change


       DeskTopSize 2X2


  to


       DeskTopSize 1X1


  This eliminates the virtual desktops.

  Next, in the Default Styles section, change


       Style "*"           BorderWidth 7, HandleWidth 7


  to


       Style "*"           BorderWidth 0, HandleWidth 0, notitle, nohandles


  This will disable most of the normal windowing controls.

  Add the following two lines to the Default Styles section:


       Style "xdaliclock"  StaysOnTop
       Style "sxpm"        StaysOnTop


  The Default Styles part of the file should look something like this
  when you finish:


       # default Styles:
       #Style "*"           BorderWidth 7, HandleWidth 7
       Style "*"           BorderWidth 0, HandleWidth 0, notitle, nohandles
       Style "*"           Icon unknown1.xpm, Color lightgrey/dimgrey
       Style "*"           MWMFunctions, MWMDecor, HintOverride
       Style "*"           DecorateTransient, NoPPosition
       Style "*"           IconBox 0 -10 -280 -1
       Style "*"           FocusFollowsMouse
       Style "*"           RandomPlacement, SmartPlacement
       Style "xdaliclock"  StaysOnTop
       Style "sxpm"        StaysOnTop


  You can use the xdaliclock and sxpm programs to cover up parts of
  Netscape Navigator. The ``StaysOnTop'' attribute is the active
  ingredient.

  Next, find the following four lines and comment them out as shown:


       #AddToFunc InitFunction         "I" Module FvwmButtons
       #+                      "I" exec xsetroot -mod 2 2 -fg \#554055 -bg \#705070

       #AddToFunc RestartFunction "I" Module FvwmButtons
       #+                      "I" exec xsetroot -mod 2 2 -fg \#554055 -bg \#705070

  Commenting out these lines will eliminate the nice task launcher from
  FVWM2, which is okay because you're after as simple an environment as
  you can create.


  33..22..  NNeettssccaappee NNaavviiggaattoorr

  Netscape Navigator is a better choice for setting up a kiosk than
  Netscape Communicator. Being simpler, there are fewer objects to hide.

  Under Microsoft Windows, Netscape Navigator has a kiosk mode that
  eliminates most of the Navigator controls but there is, at the time of
  this writing, no built-in kiosk mode for the Unix version of
  Navigator.

  The Unix version can, however, be invoked with a -geometry argument
  that allows us to always start Netscape full screen. This forms part
  of our strategy for a Netscape-based kiosk.

  You need to decide on our kiosk screen resolution. Using a 19- or
  20-inch monitor, we found 640x480 too large, 1024x768 too small, and
  800x600 just about right for public viewing (you may decide
  differently). Once you decide on the resolution, you are ready to
  begin adjusting Navigator. For the rest of this HOWTO we assume
  800x600 resolution. You'll need to adjust accordingly if you select a
  different resolution.

  _N_o_t_e_: Navigator is going to be invoked by root during bootup, so make
  all of the Netscape adjustments under the root account in the
  /root/.netscape directory.

  Invoke Netscape and click into the Edit, Preferences dialog. Under
  Appearance check ``Show Toolbar as Text Only.''  Under Appearance,
  Fonts adjust both fixed- and variable-width fonts to at least 14pt or
  the screen display will be too small for comfortable reading.

  Under Preferences, Navigator insert the URL of your kiosk home page.
  If you're running a local version of Apache or another web server,
  make this http://localhost/ for top level access, or deeper into the
  html doctree if desired.

  Save these options, then click View on the Navigator menu bar.
  Deselect Personal Toolbar and Location Bar.

  Notice how much more kiosk-like the interface has become? When you
  exit Navigator, these settings will be saved.

  If you look closely at your adjusted Navigator screen, you'll see four
  areas that need to be covered and protected from mouse or trackball
  clicks:


  1. The Toolbar at the top

  2. The twister at the left-hand side of the navigation toolbar

  3. The rest of the navbar to the right of Home

  4. The security key in the lower left-hand corner of Navigator.

  Here's a rough schematic of the areas you need to mask:

       +---------------------------------------+
       |            # 1 Toolbar                |
       +--+------------+-----------------------+
       |#2|            |  #3 Navbar            |
       +--+            +-----------------------+
       |                                       |
       |                                       |
       |                                       |
       |                                       |
       |                                       |
       |                                       |
       |                                       |
       |                                       |
       |                                       |
       |                                       |
       +--------+                              |
       |#4 Key  |                              |
       +---------------------------------------+


  To mask over the top areas (#1-3), we'll need three graphic images. To
  mask the security key (#4) we'll use xdaliclock.


  33..33..11..  CCrreeaattiinngg tthhee GGrraapphhiiccaall MMaasskkss

  The easiest way to create graphical masks to cover areas #1-3 is to
  grab a screenshot of Navigator in full 800x600 mode and then crop out
  areas that correspond to #1-3. I used GIMP for this.

  You can then re-design the basic graphics, changing the colors if you
  wish, or putting your own logo on them. Save them as:


  1. topbar.xpm

  2. navleft.xpm

  3. navright.xpm

  The xpm format is the native X Window bitmap format. You will use the
  X Window program _s_x_p_m to place them on the screen.

  Creating the masks with just the right number of pixels and just the
  right placement on the monitor requires some experimentation. For your
  convenience, I have placed the xpm files we created plus our
  configuration files in at the following web site:
  <http://www.rom.on.ca/kiosk/HOWTO/>. You may find it simpler to
  download our masks and use them as a starting point for your own
  graphics.


  33..44..  //rroooott//kkiioosskk..xxiinniittrrcc

  Just as you would normally create a .xinitrc file for your personal
  use, you must create an X Window session initialization file for our
  kiosk application. The following script implements a number of
  features:


  +o  Screensaver initialization (optional)

  +o  Placement of graphic bitmap over Navigator menu bar (topnav.xpm)

  +o  Placement of graphic bitmap over navigation bar twiser
     (navleft.xpm)

  +o  Placement of graphic bitmap over rest of navbar (navright.xpm)

  +o  Xdaliclock placement over Navigator security key (adjusted for
     800x600 screen resolution)

  +o  Netscape startup and loop checks to make sure Navigator is running,
     and to re-run it if it isn't.

  This is the main file that runs the kiosk.


  ______________________________________________________________________
  #!/bin/sh

          fi
          /usr/bin/netscape -geometry 800x600

  # This should never be reached
  ______________________________________________________________________

  You can now start testing your kiosk setup. Since you will need to do
  this repeatedly, manually, as well as from an initialization script,
  create the following as a shell script named /root/xkiosk:


  ______________________________________________________________________
  /usr/X11R6/bin/xinit /root/kiosk.xinitrc -- /usr/X11R6/bin/X \
  -xf86config /root/kiosk.XF86Config bc
  ______________________________________________________________________


  Because you will be testing often, and reusing this later when you
  automate the startup, create this command as a shell script called
  /root/xkiosk. Be sure to chmod ug+x it.

  Under normal (i.e. kiosk) conditions, Linux should boot straight into
  Kiosk mode. In the event of a power failure, accidental reboot, or
  scheduled reboot, you need to configure the system to do this.

  For our kiosk we elected to use init level 4, which is normally
  unused, for kiosk mode. We made the following adjustment to
  /etc/inittab:


  44..11..  //eettcc//iinniittttaabb mmooddiiffiiccaattiioonnss


  ______________________________________________________________________
  # Default runlevel. The runlevels used by RHS are:
  #   0 - halt (Do NOT set initdefault to this)
  #   1 - Single user mode
  #   2 - Multiuser, without NFS (The same as 3, if you do not have networking)
  #   3 - Full multiuser mode
  #   4 - Kiosk mode
  #   5 - X11
  #   6 - reboot (Do NOT set initdefault to this)
  #
  id:4:initdefault:
  ______________________________________________________________________


  44..22..  //eettcc//rrcc..dd//rrcc..44//SS9999xxkkiioosskk rruunnlleevveell ssccrriipptt

  To initialize the kiosk after everything else has been initialized,
  including, in our case, Apache and MySQL, create the file
  /etc/rc.d/rc.4/S99xkiosk:


  ______________________________________________________________________
  #!/bin/bash
  #
  # S99xkiosk   Initialization of kiosk for runlevel 4
  #
  # Author:           Gene Wilburn <genew@rom.on.ca>
  #

  # Display message on console
  echo "Starting up the X Window Kiosk ... "

  if [ -f /.netscape/lock] ; then
     rm /.netscape/lock
  fi

  # Logging of X activity
  echo %%%%%%%%%%%%%Reboot%%%%%%%%%% >> /var/log/xlog
  /root/xkiosk

  # This point should only be reached by pressing Ctrl-Backspace
  /sbin/shutdown -r now

  # All done.
  ______________________________________________________________________


  Once this file has been created and inittab has been adjusted to boot
  into init level 4, Linux will boot directly into kiosk mode. On our
  kiosk we disable telnet and ftp and install ssh so we can maintain and
  administer the kiosk remotely across the network with ssh and scp.

  There are times, especially during testing, when you'd like to work
  from the console in a normal init level 3 mode. To do this, press

  Depending on where you deploy your kiosk, you may not want all the
  default xscreensaver images to appear. For our _H_a_n_d_s_-_O_n _B_i_o_d_i_v_e_r_s_i_t_y
  _G_a_l_l_e_r_y we wanted to display only the animated fractal images that
  suggested life science themes.

  After testing out several screensaver images, we decided that we to
  select randomly between two choices: _c_o_r_a_l and _f_o_r_e_s_t.

  To limit xscreensaver to displaying these two, we created the file
  .xscreensaver in the filesystem root (/) with the following options:

  Our kiosk machine contains a Sound Blaster AWE64 card with attached
  speakers. We chose this card specifically because it works well with
  Linux sound drivers.

  The MySQL database that drives our Biodiversity Gallery kiosk points
  to a collection of sound files that a visitor may listen to, including
  a ``bird song quiz.'' The downside of using Linux Netscape for a kiosk
  is that some of the multimedia aspects are primitive, compared to
  Windows and Macintosh.

  To enable sound, we implemented a Unix Netscape plugin called Xswallow
  written by Caolan McNamara (
  <http://skynet.csn.ul.ie/~caolan/docs/XSwallow.html>). All the sound
  plugins we tested create a separate web page as the sound is being
  played (unless the sound file is embedded). Of the programs we tested,
  Xswallow worked the best and had the cleanest display page.

  Although the extra page is inconvenient, we decided that having the
  stability of Linux was more important than the extra click required to
  return to the previous screen.

  An additional problem is that when a sound is selected, the Xswallow
  page displays ``Click to Abort Swallow of type audio/basic''. Clicking
  merely returns a blank page. I made a slight change to the author's
  source code for UnixShell.c, changing


       char *text2 = "Click to Abort Swallow";


  to read


       char *text2 = "Click BACK Button to return from playing file";


  The phrase ``of type audio/basic'' appears to come directly from
  Netscape rather than Xswallow.

  After recompiling, I added the plugin to Netscape.

  A last note about sound files: the original set of files we received
  were a mix of .au and .wav files. Our experience was that the .au
  files worked the most reliably in Linux and we converted all sound
  files to .au format.

  Not having the funding for a touchscreen display, we opted for a
  trackball (and no keyboard) for our kiosk navigation. Our colleague,
  Andy Rauer at the Ontario Science Centre in Toronto, tipped us off to
  using ``industry-strength'' trackball components from Happ Conrols
  Inc., Elk Grove Village, Illinois  <http://www.happcontrols.com/>
  (check under their Interactives section).

  One of the things we needed to do was disable any right-mouse button
  click equivalents from being used in Netscape Navigator because right-
  click events invoke user dialogs.

  By building our own trackball, we were able to wire it any way we
  wanted. We wired in two push-button controls, both with a left-mouse
  button equivalent. The buttons are arranged on either side of the
  trackball, allowing ease of use from right-handed and left-handed
  visitors. Our gallery designers then took the trackball parts and
  built them into the gallery's kiosk enclosure.

  For our kiosk we purchased the following components for building a
  heavy-duty trackball designed to withstand visitor use (and abuse):


  +o  A 2 1/4-inch Atari Trackball Assembly (we selected red)

  +o  Trackball Interface Kit for IBM (Microsoft serial mouse compatible)

  +o  Illuminated Push Buttons (red)

  From a local electronics vendor, we purchased a Hammond Manufacturing
  plastic handy case (Cat no. 1591ABK) for housing the electronics board
  for the trackball.

  Anticipating additional kiosks, and potential part failure, we ordered
  four sets of each of the above for spare parts and testing.

  In the best of all possible worlds, you will have the opporunity to
  design your kiosk pages from scratch. Bearing in mind that using a
  kiosk is a different experience from sitting at a desk browsing the
  web from a personal workstation, the following guidelines are useful
  design principles:


  +o  Keep text passages very short and use large fonts.

  +o  Avoid screens that require scrolling.

  +o  Use colorful, large, eye-catching images on every page

  +o  Create embedded navigation if possible, e.g., return to previous
     page, go to next page, go to kiosk menu, etc., should all be
     designed right into the pages themselves.

  +o  Avoid anything that requires a keyboard. Design for clicking.

  +o  If you use sound files, keep the duration short. Embed them into
     the page if possible.

  +o  Make everything punchy and snappy. Design for short attention spans
     and pass-through traffic. Save your theses and exegeses for
     elsewhere.

  Unforunately you will sometimes inherit pages that were designed for
  web browsing rather than kiosk browsing. In these cases it may be too
  time-consuming or too difficult to redesign them as kiosk pages. When
  implementing standard web pages for a kiosk display:


  +o  Remove all external A HREF's, including MAILTO's.

  +o  Remove all unnecessary verbiage, logos, etc. from the pages.

  +o  Check font sizes and increase if necessary.

  +o  Remove any animated GIF's that don't pertain directly to the pages
     being viewed.

  +o  Actually, remove any animated GIF's, period.

  +o  Do anything else you can to simplify the page design.

  +o  Check into using server-side includes to add some fundamental
     navigation or a consistent graphic to tie the pages together.

  Our previous attempts at creating browser-based kiosks with Windows-
  based PC's were unsatisfactory. The units were unstable, freezing up
  frequently. The Linux approach has given us a reliable, robust kiosk
  in a public gallery that has stood up well to visitor usage. Our
  success with this project has led us to consider other kiosk
  possibilities.

  One of our future goals is to implement remote kiosks in the greater
  Toronto area where people can browse some of our site information and,
  hopefully, be attracted enough by it to visit the ROM in person. These
  might be deployed at places such as conventions, trade shows, shopping
  malls or special exhibits. We are also thinking in terms of deploying
  kiosks in more distant locations, perhaps in public libraries.

  For this project we would likely implement modem-based Linux boxes
  that could ``call home'' to update files on a routine basis and could
  be dialled into for maintenance and updates.

  When the technology gets cheaper, we would like to experiment with
  flat-panel touchscreen displays for kiosks. The combination of flat-
  panel display and very small PC units would enable us to deploy kiosks
  with a very small footprint.

  Ultimately we may need to deploy kiosks that utilize keyboards. This
  will present a new set of challenges in terms of blocking unwanted
  keystrokes. If anyone would like to contribute information on this, or
  to any other aspect of the Kiosk-HOWTO, please email me at
  genew@rom.on.ca or my alternative email address njo@interlog.com.

  I would be very interested in collaborating with other kiosk builders
  to extend the Kiosk-HOWTO for other situations. Kiosks are a bit like
  Perl: ``There is more than one way to do it.''
