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. diff --git a/trunk/drivers/hid/Kconfig b/trunk/drivers/hid/Kconfig index 6369ba7f96f8..b07440a172b5 100644 --- a/trunk/drivers/hid/Kconfig +++ b/trunk/drivers/hid/Kconfig @@ -376,6 +376,13 @@ config HID_ROCCAT_KONE ---help--- Support for Roccat Kone mouse. +config HID_ROCCAT_PYRA + tristate "Roccat Pyra mouse support" + depends on USB_HID + select HID_ROCCAT + ---help--- + Support for Roccat Pyra mouse. + config HID_SAMSUNG tristate "Samsung" depends on USB_HID diff --git a/trunk/drivers/hid/Makefile b/trunk/drivers/hid/Makefile index 46f037f3df80..d224fa342187 100644 --- a/trunk/drivers/hid/Makefile +++ b/trunk/drivers/hid/Makefile @@ -52,6 +52,7 @@ obj-$(CONFIG_HID_PETALYNX) += hid-petalynx.o obj-$(CONFIG_HID_PICOLCD) += hid-picolcd.o obj-$(CONFIG_HID_ROCCAT) += hid-roccat.o obj-$(CONFIG_HID_ROCCAT_KONE) += hid-roccat-kone.o +obj-$(CONFIG_HID_ROCCAT_PYRA) += hid-roccat-pyra.o obj-$(CONFIG_HID_SAMSUNG) += hid-samsung.o obj-$(CONFIG_HID_SMARTJOYPLUS) += hid-sjoy.o obj-$(CONFIG_HID_SONY) += hid-sony.o diff --git a/trunk/drivers/hid/hid-core.c b/trunk/drivers/hid/hid-core.c index 0c52899be964..18608b89e76b 100644 --- a/trunk/drivers/hid/hid-core.c +++ b/trunk/drivers/hid/hid-core.c @@ -1367,6 +1367,7 @@ static const struct hid_device_id hid_blacklist[] = { { HID_USB_DEVICE(USB_VENDOR_ID_QUANTA, USB_DEVICE_ID_QUANTA_OPTICAL_TOUCH) }, { HID_USB_DEVICE(USB_VENDOR_ID_QUANTA, USB_DEVICE_ID_PIXART_IMAGING_INC_OPTICAL_TOUCH_SCREEN) }, { HID_USB_DEVICE(USB_VENDOR_ID_ROCCAT, USB_DEVICE_ID_ROCCAT_KONE) }, + { HID_USB_DEVICE(USB_VENDOR_ID_ROCCAT, USB_DEVICE_ID_ROCCAT_PYRA_WIRED) }, { HID_USB_DEVICE(USB_VENDOR_ID_SAMSUNG, USB_DEVICE_ID_SAMSUNG_IR_REMOTE) }, { HID_USB_DEVICE(USB_VENDOR_ID_SAMSUNG, USB_DEVICE_ID_SAMSUNG_WIRELESS_KBD_MOUSE) }, { HID_USB_DEVICE(USB_VENDOR_ID_SONY, USB_DEVICE_ID_SONY_PS3_CONTROLLER) }, diff --git a/trunk/drivers/hid/hid-ids.h b/trunk/drivers/hid/hid-ids.h index 85c6d13c9ffa..5787b1a1339f 100644 --- a/trunk/drivers/hid/hid-ids.h +++ b/trunk/drivers/hid/hid-ids.h @@ -459,6 +459,8 @@ #define USB_VENDOR_ID_ROCCAT 0x1e7d #define USB_DEVICE_ID_ROCCAT_KONE 0x2ced +#define USB_DEVICE_ID_ROCCAT_PYRA_WIRED 0x2c24 +#define USB_DEVICE_ID_ROCCAT_PYRA_WIRELESS 0x2cf6 #define USB_VENDOR_ID_SAITEK 0x06a3 #define USB_DEVICE_ID_SAITEK_RUMBLEPAD 0xff17 diff --git a/trunk/drivers/hid/hid-ntrig.c b/trunk/drivers/hid/hid-ntrig.c index 69169efa1e16..fb69b8c4953f 100644 --- a/trunk/drivers/hid/hid-ntrig.c +++ b/trunk/drivers/hid/hid-ntrig.c @@ -90,55 +90,6 @@ struct ntrig_data { };
