+N-Trig touchscreen Driver
+-------------------------
+ Copyright (c) 2008-2010 Rafi Rubin <rafi@seas.upenn.edu>
+ Copyright (c) 2009-2010 Stephane Chatty
+
+This driver provides support for N-Trig pen and multi-touch sensors. Single
+and multi-touch events are translated to the appropriate protocols for
+the hid and input systems. Pen events are sufficiently hid compliant and
+are left to the hid core. The driver also provides additional filtering
+and utility functions accessible with sysfs and module parameters.
+
+This driver has been reported to work properly with multiple N-Trig devices
+attached.
+
+
+Parameters
+----------
+
+Note: values set at load time are global and will apply to all applicable
+devices. Adjusting parameters with sysfs will override the load time values,
+but only for that one device.
+
+The following parameters are used to configure filters to reduce noise:
+
+activate_slack number of fingers to ignore before processing events
+
+activation_height size threshold to activate immediately
+activation_width
+
+min_height size threshold bellow which fingers are ignored
+min_width both to decide activation and during activity
+
+deactivate_slack the number of "no contact" frames to ignore before
+ propagating the end of activity events
+
+When the last finger is removed from the device, it sends a number of empty
+frames. By holding off on deactivation for a few frames we can tolerate false
+erroneous disconnects, where the sensor may mistakenly not detect a finger that
+is still present. Thus deactivate_slack addresses problems where a users might
+see breaks in lines during drawing, or drop an object during a long drag.
+
+
+Additional sysfs items
+----------------------
+
+These nodes just provide easy access to the ranges reported by the device.
+sensor_logical_height the range for positions reported during activity
+sensor_logical_width
+
+sensor_physical_height internal ranges not used for normal events but
+sensor_physical_width useful for tuning
+
+All N-Trig devices with product id of 1 report events in the ranges of
+X: 0-9600
+Y: 0-7200
+However not all of these devices have the same physical dimensions. Most
+seem to be 12" sensors (Dell Latitude XT and XT2 and the HP TX2), and
+at least one model (Dell Studio 17) has a 17" sensor. The ratio of physical
+to logical sizes is used to adjust the size based filter parameters.
+
+
+Filtering
+---------
+
+With the release of the early multi-touch firmwares it became increasingly
+obvious that these sensors were prone to erroneous events. Users reported
+seeing both inappropriately dropped contact and ghosts, contacts reported
+where no finger was actually touching the screen.
+
+Deactivation slack helps prevent dropped contact for single touch use, but does
+not address the problem of dropping one of more contacts while other contacts
+are still active. Drops in the multi-touch context require additional
+processing and should be handled in tandem with tacking.
+
+As observed ghost contacts are similar to actual use of the sensor, but they
+seem to have different profiles. Ghost activity typically shows up as small
+short lived touches. As such, I assume that the longer the continuous stream
+of events the more likely those events are from a real contact, and that the
+larger the size of each contact the more likely it is real. Balancing the
+goals of preventing ghosts and accepting real events quickly (to minimize
+user observable latency), the filter accumulates confidence for incoming
+events until it hits thresholds and begins propagating. In the interest in
+minimizing stored state as well as the cost of operations to make a decision,
+I've kept that decision simple.
+
+Time is measured in terms of the number of fingers reported, not frames since
+the probability of multiple simultaneous ghosts is expected to drop off
+dramatically with increasing numbers. Rather than accumulate weight as a
+function of size, I just use it as a binary threshold. A sufficiently large
+contact immediately overrides the waiting period and leads to activation.
+
+Setting the activation size thresholds to large values will result in deciding
+primarily on activation slack. If you see longer lived ghosts, turning up the
+activation slack while reducing the size thresholds may suffice to eliminate
+the ghosts while keeping the screen quite responsive to firm taps.
+
+Contacts continue to be filtered with min_height and min_width even after
+the initial activation filter is satisfied. The intent is to provide
+a mechanism for filtering out ghosts in the form of an extra finger while
+you actually are using the screen. In practice this sort of ghost has
+been far less problematic or relatively rare and I've left the defaults
+set to 0 for both parameters, effectively turning off that filter.
+
+I don't know what the optimal values are for these filters. If the defaults
+don't work for you, please play with the parameters. If you do find other
+values more comfortable, I would appreciate feedback.
+
+The calibration of these devices does drift over time. If ghosts or contact
+dropping worsen and interfere with the normal usage of your device, try
+recalibrating it.
+
+
+Calibration
+-----------
+
+The N-Trig windows tools provide calibration and testing routines. Also an
+unofficial unsupported set of user space tools including a calibrator is
+available at:
+http://code.launchpad.net/~rafi-seas/+junk/ntrig_calib
+
+
+Tracking
+--------
+
+As of yet, all tested N-Trig firmwares do not track fingers. When multiple
+contacts are active they seem to be sorted primarily by Y position.

+/*
+ * Original Media Tablet 10.6 inch report descriptor.
+ *
+ * There are at least two versions of this model in the wild. They are
+ * represented by Genius G-Pen M609 (older version) and Genius G-Pen M609X
+ * (newer version).
+ *
+ * Both versions have the usual pen with two barrel buttons and two
+ * identical wheels with center buttons in the top corners of the tablet
+ * base. They also have buttons on the top, between the wheels, for
+ * selecting the wheels' functions and wide/standard mode. In the wide mode
+ * the whole working surface is sensed, in the standard mode a narrower area
+ * is sensed, but the logical report extents remain the same. These modes
+ * correspond roughly to 16:9 and 4:3 aspect ratios respectively.
+ *
+ * The older version has three wheel function buttons ("scroll", "zoom" and
+ * "volume") and two separate buttons for wide and standard mode. The newer
+ * version has four wheel function buttons (plus "brush") and only one
+ * button is used for selecting wide/standard mode. So, the total number of
+ * buttons remains the same, but one of the mode buttons is repurposed as a
+ * wheels' function button in the newer version.
+ *
+ * The wheel functions are:
+ * scroll - the wheels act as scroll wheels, the center buttons switch
+ * between vertical and horizontal scrolling;
+ * zoom - the wheels zoom in/out, the buttons supposedly reset to 100%;
+ * volume - the wheels control the sound volume, the buttons mute;
+ * brush - the wheels are supposed to control brush width in a graphics
+ * editor, the buttons do nothing.
+ *
+ * Below is the newer version's report descriptor. It may very well be that
+ * the older version's descriptor is different and thus it won't be
+ * supported.
+ *
+ * The mouse report (ID 1) only uses the wheel field for reporting the tablet
+ * wheels' scroll mode. The keyboard report (ID 13) is used to report the
+ * wheels' zoom and brush control functions as key presses. The report ID 12
+ * is used to report the wheels' volume control functions. The stylus report
+ * (ID 16) has the same problems as the Slim Tablet 5.8 inch report has.
+ *
+ * The rest of the reports are unused, at least in the default configuration.
+ * The purpose of the features is unknown.

+ * descriptors are identical for both versions.
+ *
+ * The function, behavior and report descriptor of this tablet is similar to
+ * that of Media Tablet 10.6 inch. However, there is one more field (with
+ * Consumer AC Pan usage) in the mouse description. Then the tablet X and Y
+ * logical extents both get scaled to 0..16383 range (a hardware limit?),
+ * which kind of defeats the advertised 4000 LPI resolution, considering the
+ * physical extents of 12x7.25 inches. Plus, reports 5, 10 and 255 are used
+ * sometimes (while moving the pen) with unknown purpose. Also, the key codes
+ * generated for zoom in/out are different.
