If it is determined that the second user in the body of water is inside the first target region relative to the first user, the displayed virtual reality content includes a representation of the second user.

A face device for monitoring biomedical parameters of a user provides a support and housing structure shaped so as to be applied to the head of the user, an oximetry sensor fitted to the support and housing structure so as to adhere, in an operating position, to the face of the user at the facial artery, a sound source fitted to the support and housing structure so as to adhere, in an operating position, to a cranial bone of the user, an independently powered electronic board for processing data, received in the support and housing structure and connected to the oximetry sensor and to the sound source so as to detect and process signals coming from the oximetry sensor and to provide information on biomedical parameters to the user acoustically through the sound source. This face device does not engage or distract the user.

An electronic directional indicator includes a microcontroller in electronic communication with an electronic compass, an electronic motion-detecting module and at least one light source that is controllably illuminable. A battery life of the electronic directional indicator is managed by monitoring the electronic motion-detecting module for motion within pre-defined time periods and reducing power to electronic components accordingly. The electronic directional indicator can be placed on the face shield portion of a self-contained breathing apparatus face mask to provide a constant source of orientation for fire-fighters in reduced- or zero-visibility environments.

The present invention relates to an enhanced electronic diving mask with various image enhancement hardware and software integrated with a diving mask, whereby images may be enhanced to enable a diver to achieve greater visibility and clearer vision while underwater. Notably, the present invention combines techniques that have previously been used in connection with internal patient surgical procedures, so that medical instrument imaging technology used inside the human body may for the first time be used to afford divers clearer vision, more visibility and greater safety.

Disclosed herein are systems for providing virtual reality or mixed reality experiences to riders of a waterslide. In some embodiments, the system comprises a plurality of beacons or markers disposed along the waterslide, and a waterproof virtual reality (VR) headset for presenting virtual reality or mixed reality content to a person wearing the waterproof VR headset and riding the waterslide, wherein each of the plurality of beacons or markers is configured to be detectable to facilitate coordinated presentation of the virtual reality or mixed reality content to the person wearing the waterproof VR headset and riding the waterslide based at least in part on a location of the person along the waterslide.

Systems and methods for dive masks with multiple interfaces in accordance with embodiments of the invention are illustrated. Dive masks include dive device data interfaces that obtain dive device data by communicating with dive devices. Dive masks can additionally include configuration interfaces that obtain configuration data through wireless communication with configuration devices. Furthermore, a dive mask can have a display processing application which can receive configuration data, receive dive device data, and display dive device data in accordance with configuration data.

The present invention relates to an underwater VR headset (1) comprising a diving mask (10), which can be placed on a diver's head on the diver's face in a viewing direction (5), and an underwater display unit (20), wherein the underwater display unit (20) is arranged behind the diving mask (10) in the viewing direction (5) of the diver, wherein the underwater display unit (20) comprises a housing (22) and at least one VR display unit (25) arranged in the housing (22), wherein a virtual reality displayed by the VR display unit (25) can be perceived by the diver through the diving mask (10) and the housing (22), and wherein the housing (22) is gas-tight and liquid-tight. Moreover, the present invention relates to a diving mask (10) and an underwater display unit (20).

A dive mask provides underwater images and includes: a transparent lens; a frame; a strap arrangement; a water-proof housing; a camera; and batteries. A first portion of the frame receives the transparent lens, and a second portion mounts to a wearer's face. The strap arrangement secures the frame to the wearer's head. The water-proof housing is secured within the frame, with a least a portion thereof being sealed against a portion of the transparent lens. The camera is positioned within the water proof enclosure, and include a shutter button that may be depressed to capture still images or video recordings. The batteries are positioned in the water-proof housing and power the camera. A water proof port permits recharging of the batteries. A waterproof pouch with a re-sealable waterproof closure is releasably secured to one strap using a lanyard, and stores the user's personal belongings while diving.

Disclosed herein are systems and methods for providing VR/MR experiences to users in water through a headset and at least one special-effects device. During a VR/MR experience, a controller may send commands to a special-effects device at particular times to cause the special-effects device to create effects in synchronism with the visual portion of the VR/MR experience. A headset application that provides the visual portion of the VR/MR experience may communicate with the controller before the experience begins to establish the identity of the experience and the start time. The VR/MR experience may be selected by reading a storage medium (e.g., a near-field communication (NFC) card) that identifies the experience and/or the controller. Some information on the storage medium may be included in a metadata file transferred to the application. The application may send information read from the storage medium to the controller via an over-the-air network.
