Abstract: Methods, apparatus, and computer-readable media are described herein related to biometric authentication. A first computing device can detect a machine-readable code displayed by a second computing device, where the machine-readable code can identify protected information viewable via the second computing device.

Abstract: A wearable computing device such as a head-mounted display (HMD) may be equipped with a magnetometer for detecting presence and motion of a hand-wearable magnet (HWM). The HMD may analyze magnetic field measurements of the magnetometer to determine when the HWM moves within a threshold distance of the magnetometer, and may thereafter determine one or more patterns of motion of the HWM based the magnetic field measurements. The HMD may operate in a background detection state in order to determine a background magnetic field strength and to monitor for magnetic disturbances from the HWM. Upon occurrence of a trigger event corresponding to magnetic disturbance above a threshold level, the HMD may transition to operating in a gesture detection state in which it analyzes magnetometer measurements for correspondence with known gestures. Upon recognizing a known gesture, the HMD may carry out one or more actions based on the recognized known gesture.

An example system may be configured to: (a) cause a visual depiction of a first reference marker on a graphical display; (b) receive first input data indicating an initial touch input on a touch-based user-interface, where the initial touch input corresponds to an input-direction path having a first end and a second end, and where the touch input corresponds to movement of the input-direction path; (c) associate movement of the first reference marker with subsequent touch inputs; (d) receive second input data indicating a subsequent touch input; and (e) cause a visual depiction of movement of a second reference marker.

Abstract: Implementations generally relate to creating groups in a social network system. In one implementation, a method includes identifying at least one person that is proximate to a target user in a social network system, determining that the target user is generating a pattern; recognizing the at least one person proximate to the target user who is generating the pattern; creating a group in the social network system, and the group includes the at least one person generating the pattern; and associating the group with the target user.

Abstract: Example methods and systems use multiple sensors to determine whether a speaker is speaking. Audio data in an audio-channel speech band detected by a microphone can be received. Vibration data in a vibration-channel speech band representative of vibrations detected by a sensor other than the microphone can be received. The microphone and the sensor can be associated with a head-mountable device (HMD). It is determined whether the audio data is causally related to the vibration data. If the audio data and the vibration data are causally related, an indication can be generated that the audio data contains HMD-wearer speech. Causally related audio and vibration data can be used to increase accuracy of text transcription of the HMD-wearer speech. If the audio data and the vibration data are not causally related, an indication can be generated that the audio data does not contain HMD-wearer speech.

Abstract: The present description discloses systems and methods for changing the state of a device. One embodiment may include a device configured to provide a device in a first state, receive a signal indicative of first angular data of the device, and compare the first angular data to a first threshold. The device may then execute instructions to initiate a timer when the first angular data is greater than the first threshold, receive a signal indicative of a second angular data of the device, and compare the second angular data to a second threshold. When the second angular data is less than the second threshold and the time passed is within a pre-determined time period, the device may execute instructions to transition the device to a second state.

Abstract: Examples of methods and systems for providing calibration for eye gesture recognition are described. In some examples, calibration can be executed via a head-mountable device.

The head-mountable device may be configured to receive signals indicative of eye gestures from an eye gesture-detection system and in response to receiving a second command confirming that the signal is indicative of an eye gesture command, to make adjustments to the eye gesture recognition system and/or the reference signals. The head-mountable device may calibrate an eye gesture recognition system via implicit or explicit calibration, for example.

Abstract: Methods and systems are provided for authenticating access to a wearable computing device using an authentication object, such as a hand. The wearable computing device comprises a head mountable display (HMD) and an image capture device and has access to a data profile for the authentication object. The wearable computing device provides (e.g., using the HMD) an indication for positioning the authentication object within a field of view of the image capture device. After providing the indication for positioning the authentication object, the wearable computing device receives image data from the image capture device. If the wearable computing device identifies the authentication object in the image data, for example, by matching at least a portion of the image data with data in the data profile, authentication is successful and one or more functions of the wearable computing device can be enabled.
