Introduction
------------
In order to utilize the full power of the new multi-touch devices, a way to
report detailed finger data to user space is needed. This document
describes the multi-touch (MT) protocol which allows kernel drivers to
report details for an arbitrary number of fingers.
In order to utilize the full power of the new multi-touch and multi-user
devices, a way to report detailed data from multiple contacts, i.e.,
objects in direct contact with the device surface, is needed. This
document describes the multi-touch (MT) protocol which allows kernel
drivers to report details for an arbitrary number of contacts.
The protocol is divided into two types, depending on the capabilities of the
hardware. For devices handling anonymous contacts (type A), the protocol
describes how to send the raw data for all contacts to the receiver. For
devices capable of tracking identifiable contacts (type B), the protocol
describes how to send updates for individual contacts via event slots.
Usage
-----
Protocol Usage
--------------
Anonymous finger details are sent sequentially as separate packets of ABS
events. Only the ABS_MT events are recognized as part of a finger
packet. The end of a packet is marked by calling the input_mt_sync()
function, which generates a SYN_MT_REPORT event. This instructs the
receiver to accept the data for the current finger and prepare to receive
another. The end of a multi-touch transfer is marked by calling the usual
Contact details are sent sequentially as separate packets of ABS_MT
events. Only the ABS_MT events are recognized as part of a contact
packet. Since these events are ignored by current single-touch (ST)
applications, the MT protocol can be implemented on top of the ST protocol
in an existing driver.
Drivers for type A devices separate contact packets by calling
input_mt_sync() at the end of each packet. This generates a SYN_MT_REPORT
event, which instructs the receiver to accept the data for the current
contact and prepare to receive another.
Drivers for type B devices separate contact packets by calling
input_mt_slot(), with a slot as argument, at the beginning of each packet.
This generates an ABS_MT_SLOT event, which instructs the receiver to
prepare for updates of the given slot.
All drivers mark the end of a multi-touch transfer by calling the usual
input_sync() function. This instructs the receiver to act upon events
accumulated since last EV_SYN/SYN_REPORT and prepare to receive a new
set of events/packets.
accumulated since last EV_SYN/SYN_REPORT and prepare to receive a new set
of events/packets.
The main difference between the stateless type A protocol and the stateful
type B slot protocol lies in the usage of identifiable contacts to reduce
the amount of data sent to userspace. The slot protocol requires the use of
the ABS_MT_TRACKING_ID, either provided by the hardware or computed from
the raw data [5].
For type A devices, the kernel driver should generate an arbitrary
enumeration of the full set of anonymous contacts currently on the
surface. The order in which the packets appear in the event stream is not
important. Event filtering and finger tracking is left to user space [3].
For type B devices, the kernel driver should associate a slot with each
identified contact, and use that slot to propagate changes for the contact.
Creation, replacement and destruction of contacts is achieved by modifying
the ABS_MT_TRACKING_ID of the associated slot. A non-negative tracking id
is interpreted as a contact, and the value -1 denotes an unused slot. A
tracking id not previously present is considered new, and a tracking id no
longer present is considered removed. Since only changes are propagated,
the full state of each initiated contact has to reside in the receiving
end. Upon receiving an MT event, one simply updates the appropriate
attribute of the current slot.
Protocol Example A
------------------
Here is what a minimal event sequence for a two-contact touch would look
like for a type A device:
ABS_MT_POSITION_X x[0]
ABS_MT_POSITION_Y y[0]
SYN_MT_REPORT
ABS_MT_POSITION_X x[1]
ABS_MT_POSITION_Y y[1]
SYN_MT_REPORT
SYN_REPORT
The sequence after moving one of the contacts looks exactly the same; the
raw data for all present contacts are sent between every synchronization
with SYN_REPORT.
Here is the sequence after lifting the first contact:
ABS_MT_POSITION_X x[1]
ABS_MT_POSITION_Y y[1]
SYN_MT_REPORT
SYN_REPORT
And here is the sequence after lifting the second contact:
SYN_MT_REPORT
SYN_REPORT
If the driver reports one of BTN_TOUCH or ABS_PRESSURE in addition to the
ABS_MT events, the last SYN_MT_REPORT event may be omitted. Otherwise, the
last SYN_REPORT will be dropped by the input core, resulting in no
zero-contact event reaching userland.
Protocol Example B
------------------
Here is what a minimal event sequence for a two-contact touch would look
like for a type B device:
ABS_MT_SLOT 0
ABS_MT_TRACKING_ID 45
ABS_MT_POSITION_X x[0]
ABS_MT_POSITION_Y y[0]
ABS_MT_SLOT 1
ABS_MT_TRACKING_ID 46
ABS_MT_POSITION_X x[1]
ABS_MT_POSITION_Y y[1]
SYN_REPORT
Here is the sequence after moving contact 45 in the x direction:
ABS_MT_SLOT 0
ABS_MT_POSITION_X x[0]
SYN_REPORT
Here is the sequence after lifting the contact in slot 0:
ABS_MT_TRACKING_ID -1
SYN_REPORT
The slot being modified is already 0, so the ABS_MT_SLOT is omitted. The
message removes the association of slot 0 with contact 45, thereby
destroying contact 45 and freeing slot 0 to be reused for another contact.
Finally, here is the sequence after lifting the second contact:
ABS_MT_SLOT 1
ABS_MT_TRACKING_ID -1
SYN_REPORT
Event Usage
-----------
A set of ABS_MT events with the desired properties is defined. The events
are divided into categories, to allow for partial implementation. The
minimum set consists of ABS_MT_POSITION_X and ABS_MT_POSITION_Y, which
allows for multiple fingers to be tracked. If the device supports it, the

Finger Tracking
---------------
The kernel driver should generate an arbitrary enumeration of the set of
anonymous contacts currently on the surface. The order in which the packets
appear in the event stream is not important.
The process of finger tracking, i.e., to assign a unique trackingID to each
initiated contact on the surface, is left to user space; preferably the
multi-touch X driver [3]. In that driver, the trackingID stays the same and
unique until the contact vanishes (when the finger leaves the surface). The
problem of assigning a set of anonymous fingers to a set of identified
fingers is a euclidian bipartite matching problem at each event update, and
relies on a sufficiently rapid update rate.
There are a few devices that support trackingID in hardware. User space can
make use of these native identifiers to reduce bandwidth and cpu usage.

problem. At each event synchronization, the set of actual contacts is
matched to the set of contacts from the previous synchronization. A full
implementation can be found in [3].
