摘要:
Systems and methods may provide for identifying a virtual geo-fence for a plurality of devices. Additionally, a condition may be detected with respect to two or more devices in the plurality of devices, wherein a status determination may be conducted as to whether at least one of the two or more devices has left the virtual geo-fence based on the condition.

Technologies for automated context-aware media curation include a computing device that captures context data associated with media objects. The context data may include location data, proximity data, behavior data of the user, and social activity data. The computing device generates inferred context data using one or more cognitive or machine learning algorithms. The inferred context data may include semantic time or location data, activity data, or sentiment data. The computing device updates a user context model and an expanded media object graph based on the context data and the inferred context data. The computing device selects one or more target media objects using the user context model and the expanded media object graph. The computing device may present context-aware media experiences to the user with the target media objects. Context-aware media experiences may include contextual semantic search and contextual media browsing. Other embodiments are described and claimed.
摘要:
System and techniques for tracking caloric expenditure using sensor driven fingerprints are described herein. A set of outputs may be obtained from a plurality of sensors. A fingerprint may be generated using the set of outputs. The fingerprint may correspond to an activity observed by the plurality of sensors. The generated fingerprint may be compared to a set of fingerprints stored in a database. Each fingerprint of the set of fingerprints may correspond to a respective caloric expenditure. A caloric expenditure may be calculated for the activity based on the comparison. An exercise profile of a user may be updated using the caloric expenditure
摘要:
A method may include detecting motion of a mobile device and inferring from the motion a first activity of a user of the mobile device. The method may also include evaluating a signal quality of a radio signal received by a signal module and altering an operational mode of the signal module based on the signal quality and the first activity.

摘要:
A method may include calculating a first distance between first and second devices and determining a direction of a movement of the first device. The method may further include calculating a second distance between the first and second devices after the movement of the first device and determining the relative position of the first device with respect to the second device based on the direction of the movement, the first distance, and the second distance.
摘要:
A portable consumer device, such as a mobile phone or a tablet computer, may be configured to collect measurements data associated with at least one of movement of the portable consumer device or orientation of the portable consumer device, as well as data associated with an external environment of the portable consumer device. The collected data may be evaluated in order to determine motion of the portable consumer device over time and contextual information associated with the portable consumer device. A user activity may be determined based upon the determined motion and the determined contextual information. As desired, the user activity may be evaluated in association with a suitable application scenario, such as a gaming application scenario.
摘要:
Techniques for two-way authentication between two communication endpoints (e.g., two devices) using a one-way out-of-band (OOB) channel are presented. Here, in embodiments, both communication endpoints may be securely authenticated as long as the one-way OOB channel is tamper-proof. Embodiments of the invention do not require the one-way OOB channel to be private to ensure that both endpoints are securely authenticated. Since providing a two-way or private OOB channel adds to the cost of a platform, embodiments of the invention provide for a simple and secure method for two-way authentication that uses only a non-private one-way OOB channel and thus helping to reduce platform cost. Other embodiments may be described and claimed.
摘要:
Methods and apparatus relating to secure association between devices are described. In one embodiment, devices capable of communicating via a wireless channel may be authenticated via a different channel established by signal generators and/or sensors present on the devices. Other embodiments are also disclosed.
