The objective of the invention is to provide a visual rhythmic guide device for swimming training capable of emitting rhythmical flashlights with a given frequency to lead the tempo of movements such as arm stroking and leg kicking for a swimmer. To achieve the objective, the device comprises a waterproof body to house components including a control circuit board, a timer, a gravity sensor (G-Sensor), a LED light source, a screen, a battery, a connection port and a set of input keys. When the device is given a frequency by a swimmer through the input keys, the LED light source will be driven to emit rhythmical flashlights in accordance with the given frequency. The swimmer is able to wear the device on anywhere of the body as long as the rhythmical flashlights can be sensed to adjust and practice the tempo of swimming movements.

A method and system for improving holographic image simulation and presentation is provided. The method includes receiving and analyzing audio and video data associated with historical tendencies of an opponent sporting team occurring during previous sporting contests involving the opponent sporting team. Predicted tendencies of the opponent sporting team are determined with respect to a future sporting contest scheduled with a first sporting team. In response, a holographic simulation presentation is generated. The holographic simulation presentation is associated with a predicted performance of players of the opponent sporting team with respect to the future sporting contest scheduled with the first sporting team. The holographic simulation presentation is presented such that players of the first sporting team interact with holographic images of the players of the opponent sporting team during a practice session.

The present disclosure generally relates to providing perceptual notifications containing information about a measured activity-based value of a swim characteristic. In some examples, the perceptual notifications utilize colors and haptic taps to convey measured values of the swim characteristic without requiring the swimmer to interact with the perceptual notification while the swimmer is swimming.

In one aspect, a swim system may include a reverse thrust system worn by a swimmer proximate the frontal upper torso. The system provides a variable amount of reverse thrust such that the user can swim-in-place or make gradual forward progress. Importantly, this may enable a user to effectively extend a small residential pool to serve the same function as a twenty-five meter pool typically found at commercial or government facilities. The system also provides laminar current under the user while swimming, which solves the problems of leg drop, the need to out-kick the arm stroke, and turbulence and wave action around the head associated with conventional swim-in-place devices. Still further, in certain embodiments the system provides a relatively strong current in the region of the arm stroke moving away from the swimmer which provides enhanced resistance for proficient swimmers.

Disclosed embodiments include wearable devices and techniques for detecting swimming activities, classifying user motion, detecting water submersion, and monitoring performance during swimming activities. By accurately and promptly detecting swimming activities and automatically distinguishing between different swimming stroke type performed during a swimming activity, the disclosure enables wearable devices to accurately calculate user performance information when users forget to start and/or stop recording swimming activities. In various embodiments, swimming activity detection techniques may improve the selectivity of motion based methods of identifying swimming activities identification by confirming motion analysis with water immersion and pressure data analysis that detects when the wearable device is submerged in water.

A swim fin may include a foot pocket configured to receive a foot of a swimmer and a fin blade extending from the foot pocket. A relatively rigid substrate chassis may be bonded to the foot pocket. The fin blade may be relatively flexible. Fin rails may extend along the lateral edges of the fin blade. The fin rails may include a fin spine comprising a plurality of fin spine segments in linear configuration. The fin spine may be configured to provide a swim fin with predetermined hydrodynamic characteristics. The swim fin may flex within a maximum angle of attack that may be variable and dynamically changed, within a predetermined maximum attack angle range, as a function of the kicking force generated by a swimmer during a kicking cycle.

A limb motion measurement device for swimming training includes a sense glove and a sense shoe able to measure and collect the states of moving hands and feet of a swimmer in a training practice, including strength, displacement, velocity, bearing angle, number of times, frequency and time parameters, and to generate a serial of limb motion data of arm stroking and leg kicking motions. These organized and quantified limb motion data can be transmitted outwards to an external computer for the swimmer to study and to produce useful information of more efficient movements and tempos of swimming techniques. Accordingly, the limb motion measurement device for swimming training can be applied to improve swimming techniques in a scientific way.

The present invention relates to a floatable breathing device. The floatable breathing device a head unit, a mask and a snorkel. The head unit general includes an ornamental shaped outer housing, an insulated housing positioned within the outer housing and having an ornamental shape and buoyant properties, and a head receiving section provided between the outer housing and the insulated housing and contoured to a human head. The mask extends from the outer housing, while the snorkel extends through and exits a portion of the head unit above a predetermined waterline.

A swim training apparatus for use on a hand of a swimmer in water during a swimming motion, said training aid apparatus comprising: a plate member having a first surface and an opposed second surface and a leading edge and a trailing edge. The first surface has four straight grooves having a bottom and elevated sides along passing from a base of the first surface adjacent the wrist towards a top of the first surface where fingertips extend, wherein height of the elevated sides is at least 1 mm higher than a lowest point of the bottom of the groove.

According to one exemplary embodiment, an apparatus, system, method and/or computer program product may provide an electronically and programmably controlled remote virtual spectator/viewer device enabling viewer interaction with an entertainment participant in an entertainment forum via an exemplary digital video camera, digital audio microphone, speaker system, and display device system coupled via at least one communications interface to a communications network to allow a remote viewer to virtually interact with and communicate with the entertainment participant in the entertainment forum. Embodiments may include a graphical user interface configured to allow control of a digital video camera, and digital microphone in the entertainment forum, by a remote user from a remote location.
