Abstract

Claims (58)

1 . A method comprising:

generating a first radio signal using one or more beamforming techniques to determine that a wearable device is being worn by directing a radio signal comprising radio surface waves from a first communication device to a second communication device;

generating a second radio signal without using the one or more beamforming techniques to determine that the wearable device is not being worn;

measuring a signal strength associated with the first radio signal or the second radio signal received by the second communication device;

comparing the signal strength to a threshold value; and

generating an indication of a wear status associated with the wearable device based on the comparing of the signal strength to the threshold value.

2 . The method of claim 1 , further comprising:

selecting between different versions of a same augmented reality (AR) experience based on the wear status associated with the wearable device, the selecting comprising:

accessing a first build of the same AR experience implemented by the same wearable device that is associated with a first power consumption value in response to determining that the wear status indicates the wearable device is being worn by a user; and

accessing a second build of the same AR experience implemented by the same wearable device that is associated with a second power consumption value in response to determining that the wear status indicates the wearable device is not being worn by the user, the second build of the AR experience being associated with a lower power consumption value than the first build of the AR experience.

3 . The method of claim 1 , further comprising:

determining that the signal strength fails to transgress the threshold value; and

in response to determining that the signal strength fails to transgress the threshold value, updating the indication of the wear status to indicate that the wearable device is being worn by a user.

4 . The method of claim 1 , further comprising:

causing generation of the radio signal using the one or more beamforming techniques in response to receiving confirmation that the wearable device is being worn; and

storing beamforming parameters used to achieve maximized signal strength of the radio signal in association with the first and second communication devices, the maximized signal strength being stored as the threshold value indicative of the wearable device being worn.

5 . The method of claim 4 , further comprising:

instructing a user to remove the wearable device after triggering the generation of the radio signal using the one or more beamforming techniques; and

after instructing the user to remove the wearable device after triggering the generation of the radio signal using the one or more beamforming techniques, generating, without applying the one or more beamforming techniques, a second radio signal for transmission from the first communication device to the second communication device.

6 . The method of claim 5 , wherein a perimeter of a body part of the user over which the radio waves are excited comprises a wrist, skull, waist, or finger, further comprising storing a new signal strength of the second radio signal observed by the second communication device as a new threshold indicative of the wearable device not being worn.
