Abstract: Technology for a wearable heart rate monitoring device is disclosed. The wearable heart rate monitoring device can include a heart rate sensor operable to collect sensor data, a modulator operable to generate a modulated signal that includes the sensor data, a housing configured to engage a body feature or surface in a manner that allows for heart rate detection, and a communication module configured to transmit the sensor data in the modulated signal to a mobile computing device via a wired connection that is power limited. The mobile computing device is typically configured to demodulate the modulated signal in order to extract the sensor data.

Abstract: A virtual camera configuration system includes any number of cameras disposed about an area, such as an event venue. The system also includes at least one processor and at least one non-transitory, computer-readable medium communicatively coupled to the at least one processor. In certain embodiments, the at least one non-transitory, computer-readable medium is configured to store instructions which, when executed, cause the processor to perform operations including receiving a set of game data, receiving a set of audiovisual data, and receiving a set of camera presets. The operations also include generating a set of training data and training a model based on the set of training data. The operations also include generating, using the model on a second set of game data and a second set of audiovisual data, a second set of camera presets associated with the set of virtual cameras.

Abstract: Embodiments are directed to gesture recognition in a computing device. Touch-based input by the user is monitored based on an output from a touch sensor. Gestures are directed from among the touch-based input. The detected gestures are analyzed to assign gesture characteristic profiles to the detected gestures according to profiling criteria. A sequential event log is tabulated representing counts of series of gestures based on assigned characteristic profiles and on temporal sequencing of the gestures. Circumstances for invocation of gesture detection re-calibration are assessed based on the tabulated series of gestures.
