provided in class/input/event*/device/properties.
-Types:
-==========
-Types are groupings of codes under a logical input construct. Each type has a
-set of applicable codes to be used in generating events. See the Codes section
-for details on valid codes for each type.
+Event types:
+===========
+Event types are groupings of codes under a logical input construct. Each
+type has a set of applicable codes to be used in generating events. See the
+Codes section for details on valid codes for each type.
* EV_SYN:
- Used as markers to separate events. Events may be separated in time or in
* EV_FF_STATUS:
- Used to receive force feedback device status.
-Codes:
-==========
-Codes define the precise type of event.
+Event codes:
+===========
+Event codes define the precise type of event.
EV_SYN:
----------
EV_PWR events are a special type of event used specifically for power
mangement. Its usage is not well defined. To be addressed later.
+Device properties:
+=================
+Normally, userspace sets up an input device based on the data it emits,
+i.e., the event types. In the case of two devices emitting the same event
+types, additional information can be provided in the form of device
+properties.
+
+INPUT_PROP_DIRECT + INPUT_PROP_POINTER:
+--------------------------------------
+The INPUT_PROP_DIRECT property indicates that device coordinates should be
+directly mapped to screen coordinates (not taking into account trivial
+transformations, such as scaling, flipping and rotating). Non-direct input
+devices require non-trivial transformation, such as absolute to relative
+transformation for touchpads. Typical direct input devices: touchscreens,
+drawing tablets; non-direct devices: touchpads, mice.
+
+The INPUT_PROP_POINTER property indicates that the device is not transposed
+on the screen and thus requires use of an on-screen pointer to trace user's
+movements. Typical pointer devices: touchpads, tablets, mice; non-pointer
+device: touchscreen.
+
+If neither INPUT_PROP_DIRECT or INPUT_PROP_POINTER are set, the property is
+considered undefined and the device type should be deduced in the
+traditional way, using emitted event types.
+
+INPUT_PROP_BUTTONPAD:
+--------------------
+For touchpads where the button is placed beneath the surface, such that
+pressing down on the pad causes a button click, this property should be
+set. Common in clickpad notebooks and macbooks from 2009 and onwards.
+
+Originally, the buttonpad property was coded into the bcm5974 driver
+version field under the name integrated button. For backwards
+compatibility, both methods need to be checked in userspace.
+
+INPUT_PROP_SEMI_MT:
+------------------
+Some touchpads, most common between 2008 and 2011, can detect the presence
+of multiple contacts without resolving the individual positions; only the
+number of contacts and a rectangular shape is known. For such
+touchpads, the semi-mt property should be set.
+
+Depending on the device, the rectangle may enclose all touches, like a
+bounding box, or just some of them, for instance the two most recent
+touches. The diversity makes the rectangle of limited use, but some
+gestures can normally be extracted from it.
+
+If INPUT_PROP_SEMI_MT is not set, the device is assumed to be a true MT
+device.
+
Guidelines:
==========
The guidelines below ensure proper single-touch and multi-finger functionality.
BTN_{MOUSE,LEFT,MIDDLE,RIGHT} must not be reported as the result of touch
contact. BTN_TOOL_<name> events should be reported where possible.
+For new hardware, INPUT_PROP_DIRECT should be set.
+
Trackpads:
----------
Legacy trackpads that only provide relative position information must report
on the trackpad. Where multi-finger support is available, BTN_TOOL_<name> should
be used to report the number of touches active on the trackpad.
+For new hardware, INPUT_PROP_POINTER should be set.
+
Tablets:
----------
BTN_TOOL_<name> events must be reported when a stylus or other tool is active on
BTN_{0,1,2,etc} are good generic codes for unlabeled buttons. Do not use
meaningful buttons, like BTN_FORWARD, unless the button is labeled for that
purpose on the device.
+
+For new hardware, both INPUT_PROP_DIRECT and INPUT_PROP_POINTER should be set.
instead of using the one provided by the hardware.
