## Abstract

In one embodiment, a method includes accessing a first context data associated with a first touch event on a first device and accessing a second context data associated with a touch event on the first device. The touch event has been detected by a second device. The method further includes comparing the first context data with the second context data and determining, based on the comparison, whether the first touch event is the touch event detected by the second device.

## Claims

### Claim 1

A method comprising:
accessing a first context data associated with a first touch event on a first device;
accessing a second context data associated with a touch event on the first device, the touch event having been detected by a second device;
comparing the first context data with the second context data; and
determining, based on the comparison, whether the first touch event is the touch event detected by the second device.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
accessing a third context data associated with a second touch event on the first device;
accessing a fourth context data associated with a touch event on the first device, wherein touch event having been detected by a third device;
comparing the third context data to the fourth context data; and
determining, based on the comparison, whether the second touch event is the touch event detected by the third device.

### Claim 3 (depends on 1)

The method of claim 1, wherein the second context data comprises output from one or more of:
an electrode of the second device coupled to a body of a user, wherein the electrode is configured to receive a signal from the body of the user, the signal being based on an electromagnetic interference signal generated by the first device;
an accelerometer; or
a microphone.

### Claim 4 (depends on 1)

The method of claim 1, further comprising identifying a user of the second device in response to the determination that the first touch event is the touch event detected by the second device.

### Claim 5 (depends on 4)

The method of claim 4, wherein identifying the user comprises assigning the user an ID.

### Claim 6 (depends on 4)

The method of claim 4, wherein identifying the user comprises accessing information identifying the user.

### Claim 7 (depends on 4)

The method of claim 4, wherein identifying the user comprises identify the second device.

### Claim 8 (depends on 4)

The method of claim 4, further comprising authenticating the user to the first device.

### Claim 9 (depends on 4)

The method of claim 4, further comprising accessing one or more settings particular to the identified user.

### Claim 10 (depends on 1)

The method of claim 1, wherein the first device comprises a touch-sensitive device;
and
the second device comprises a wearable device.

### Claim 11 (depends on 1)

The method of claim 1, wherein:
the first context data comprises a first timestamp; and
the second context data comprises a second timestamp.

### Claim 12 (depends on 11)

The method of claim 11, further comprising determining an offset for one or more of the first timestamp and the second timestamp, wherein the comparison is further based on the offset.

### Claim 13 (depends on 11)

The method of claim 11, wherein:
the second device is associated with a first user; and
the method further comprises:
accessing a third timestamp associated with a second touch event detected by the first device,
accessing a fourth timestamp associated with a touch event on the first device, the touch event having been detected by a third device associated with a second user;
comparing the third timestamp with the fourth timestamp;
determining, based on the comparison, whether the second touch event is the touch event detected by the third device;
in response to a determination that the first touch event is the touch event detected by the second device, associating the first touch event with the first user; and
in response to a determination that the second touch event is the touch event detected by the third device, associating the second touch event with the second user.

### Claim 14

An apparatus comprising
a touch sensor; and
one or more processors coupled to the touch sensor and configured to:
determine a first context data associated with a first touch event detected by the touch sensor;
receive from a second device a second context data associated with a touch event on the apparatus, the touch event having been detected by the second device;
compare the first context data with the second context data; and
determine, based on the comparison, whether the first touch event is the touch event detected by the second device.

### Claim 15 (depends on 14)

The apparatus of claim 14, wherein the one or more processors are further configured to:
determine a third context data associated with a second touch event detected by the touch sensor;
receive from a third device a fourth context data associated with a touch event on the apparatus, the touch event having been detected by the third device;
compare the third context data to the fourth context data; and
determine, based on the comparison, whether the second touch event is the touch event detected by the third device.

### Claim 16 (depends on 14)

The apparatus of claim 14, wherein the second device comprises a wearable device.

### Claim 17 (depends on 16)

The apparatus of claim 16, wherein the second context data comprises output from one or more of:
an electrode of the second device coupled to a body of a user, wherein the electrode is configured to receive a signal from the body of the user, the signal being based on an electromagnetic interference signal generated by the first device;
an accelerometer; or
a microphone.

### Claim 18 (depends on 14)

The apparatus of claim 14, wherein the one or more processors are further configured to identify a user of the second device in response to the determination that the first touch event is the touch event detected by the second device.

### Claim 19 (depends on 14)

The apparatus of claim 14, wherein:
the first context data comprises a first timestamp; and
the second context data comprises a second timestamp.

### Claim 20

One or more non-transitory computer-readable storage media embodying logic that when executed by one or more processors cause the one or more processors to perform operations comprising:
accessing a first context data associated with a first touch event on a first device;
accessing a second context data associated with a touch event on the first device, the touch event having been detected by a second device;
comparing the first context data with the second context data; and
determining, based on the comparison, whether the first touch event is the touch event detected by the second device.
