First Claim
1. An apparatus, comprising:
- a first device, including;
a sensor to measure a first user action in connection with the first device, the first user action having a first characteristic at a first time;
a touchscreen device;
a wireless receiver to receive a signal from a second device that includes information relating to a second user action in connection with the second device, the second user action having a second characteristic at a second time, wherein the second user action comprises a motion of the second device and the second characteristic comprises a motion characteristic of the second device, and wherein the difference between the first time and the second time is between zero seconds and thirty seconds; and
a processor operatively coupled to the sensor and the wireless receiver, the processor to;
set at least one of a location, a size, or a color of a pairing spot displayed on the touchscreen device;
establish an unauthenticated wireless connection between the first device and the second device; and
authenticate the wireless connection between the first device and the second device when;
a difference between the first time associated with the first characteristic and the second time associated with the second characteristic is below a maximum value, andthe signal received by the wireless receiver includes information indicating that the second characteristic of the second user action in connection with the second device corresponds to an expected characteristic; and
the second device, wherein the second device comprises a stylus device, the second user action comprises a detection of a sensor in a tip of the stylus device that the tip of the stylus device is in contact with the pairing spot, and the first user action includes a detection by the touchscreen device that the tip of the stylus device touched the pairing spot.

Abstract
In some embodiments, a wireless pairing method involves a touchscreen on a wireless host device combined with a switch on a wireless stylus device. The wireless pairing method uses the time-coincidence of a touch on the host device screen with the detection of a tip switch press on the stylus device as a mode of out-of-band communication to authenticate a pairing of the devices. In such embodiments, a user presses a tip portion of the stylus device against a pairing spot on the host device surface; the wireless devices then form a bonded pair if the touch and/or release of the tip portion of the stylus device with respect to the host device surface are within a pre-determined time co-incidence window of the detection by the host device of that touch and/or release of the tip portion of the stylus device.
