The invention concerns an augmented vision system (1) comprising: a displaying device (3) comprising: a fixing element (31) for coupling the displaying device (3) to a head-mountable component (90) configured to be positioned in front of a 5 face (102) of a user (100), and a display body (32) being coupled to said fixing element (31) by means of a pivoting link (321, 322, 323) providing a rotation of the display body with respect to the fixing element around a rotational axis (38); the display body (32) comprising 10 a display (33) configured to display thermal data and/or images provided by a thermal sensing device (2); and a first surface portion (325) configured to enter in contact with a forehead of a user, when said head-mountable component (90) is positioned in front of the face of the user, so as to rotate the display 15 body (32) to a predefined angular positioning (381) around the rotational axis (38).

An apparatus and method for measuring a swimmer's speed and conveying the speed to the swimmer in real time includes a plurality of ultrasonic beacons each having a transducer configured to emit ultrasonic signals in a pool or other body of water within which the swimmer is swimming. A wearable, waterproof, ultrasonic receiver worn by the swimmer, receives the ultrasonic signals and generates corresponding signal data. The receiver's microcontroller captures and uses the signal data to calculate the swimmer's position and speed in real time, and conveys this information to a wearable, waterproof, user interface device worn by the swimmer, the user interface device including a near-eye display disposed on the swimmer's googles.

The present disclosure provides a heads up display (HUD) system configured for use with a pair of swimming goggles comprising first and second eye cups, a nose bridge connected to inner sides of the eye cups, and strap mounting portions on outer sides of the eye cups. The HUD system comprises an electronics and optics modules. The electronics module comprises a water tight housing and a processor, memory, power supply, sensors and a display within the water tight housing. The processor processes signals from the sensors to determine swimming performance data and controls the display to generate an image containing the swimming performance data. The optics module is mounted on one of the eye cups and is coupled to the electronics module for receiving the image from the display. The optics module extends from the electronics module and has one or more light directing features for redirecting the image toward an eye of a user to generate a redirected image.

Various devices, arrangements and methods for managing communications using a head mounted display device are described. In one aspect, tracking data is generated at least in part by one or more sensors in a head mounted display (HMD) device. The tracking data indicates one or more facial movements of a user wearing the HMD device. A patch image is obtained based on the tracking data. The patch image is merged with a facial image. Various embodiments relate to the HMD device and other methods for generating and using the patch and facial images.

A heads-up display for an item of eyewear includes a mounting means configured to mount the heads-up display to the item of eyewear; at least one sensor configured to obtain performance data; a processing unit operatively connected to the at least one sensor, and configured to process said performance data and to generate an image from said performance data; a micro display unit operatively connected to the processing unit, and configured to display the image under the control of the processing unit; and, an optical wave guide in optical communication with the micro display unit, and configured to route the image from the micro display into a field of view of a wearer of the item of eyewear. The heads-up display is configured to overlay the image into the line of sight of the wearer, such that the wearer can view their surrounding environment at the same time as the image, and therefore view their performance data real-time.

A display image is superimposed and displayed on an outside image in a preferred manner. An optical system superimposes a display image displayed on a display device onto an outside image, and leads the display image to an eye of an observer. A display control unit controls the display size and the display position of the display image on the display device so that the display image is displayed in an image superimposition region (a flat region) detected from the outside image. For example, the display control unit controls the display state of the display image in accordance with the state of the image superimposition region in the outside image. Also, the display control unit performs control to selectively display the display image in a line-of-sight region or outside the line-of-sight region in accordance with the line of sight of the observer.

The embodiments of the disclosure provide an optical system and an image enlargement device. The optical system may include a display and an optical component disposed between the display and a viewing position. The optical component may include a first reflective element and a second reflective element. The first reflective element is configured to receive an incident light emitted from the display. The second reflective element is disposed on a reflected light path of the first reflective element, and configured to receive the incident light reflected by the first reflective element and reflect the reflected incident light to a viewing position. The first reflective element and/or the second reflective element having a function of concentrating light. Therefore, when the user looks at a display of a mobile phone or a terminal, the display is enlarged by the even reflection of the first reflective element and the second reflective element, thereby improving the user experience and comfort.

A method of calibrating a wearable heads-up display includes generating visible light that is representative of the white color of the pixels of a display UI by a plurality of light sources of the wearable heads-up display and projecting the visible light to an exit pupil of the wearable heads-up display. A measured white point of the exit pupil is determined from the visible light received at the exit pupil. The measured white point of the exit pupil is compared to a target white point, and a set of factors by which to scale the power of the light sources is determined based on the comparison. The method may be applied to all the exit pupils of the wearable heads-up display such that the wearable heads-up display has a uniform white point across all the exit pupils.
