Holoswim: Smart AR Swimming Goggles

Swimming is one of those sports in which stopping to check a smartwatch can be quite disruptive. Because of this, we've recently seen a number of performance-tracking goggles hit the market. One of the newest, known as Holoswim.

Developed by Hong Kong-based startup Guangli, the Holoswim setup consists of a fairly normal-looking set of swim goggles with a waterproof electronics module on one side, which is paired to a dedicated iOS/Android app on the wearer's smartphone. And it’s priced at $99.

Guangli's holographic display and perception technology has made swimming goggles intelligent ever since.

Holoswim smart swimming goggles, through the holographic resin optical waveguide technology to achieve smart display, using sporty resin material design, no glass components, while ensuring the safety of sports, while greatly reducing the weight of the body, the whole machine is less than 75g, and the waterproof level reaches IP68.

Holoswi smart swimming goggles have a field of view of 25° and a transmittance of up to 78%. They are very friendly to myopic users. Users within 800 degrees can customize myopic lenses to achieve comfortable wearing. The polarized coating on the surface of the swimming goggles can effectively prevent ultraviolet rays, protect the eyes, and prevent glare from interfering with the line of sight. So that every user can enjoy the clear underwater digital world.

Holoswim has two modes: indoor water and open water. Through the built-in motion sensor and original algorithm, it can obtain and calculate the sports fitness data including swimming style in real time, and display it in front of the user in real time through the holographic resin optical waveguide, even if the user is in the water. You can also see your own real-time swimming data underneath. There are as many as 17 data combinations, such as swimming time/speed, stroke frequency/ frequency, calorie consumption, etc.

Users start by utilizing the app to design a training program for themselves to follow. An IMU (inertial measurement unit) in the goggles' module subsequently tracks their movements as they swim.

An OLED holographic display in the module-side lens is thus able to show real-time data such as total distance swum, number of strokes, number of laps, 100-meter stroke pace, and total elapsed time. Users can switch between displays by pressing a physical pushbutton on the module. And after each training session, they can review their performance on the app.

Additionally, because the goggles are linked to the user's poolside phone via Bluetooth, the display will alert them to incoming calls – this function only works within a range of 5 meters (16 ft) if the goggles are underwater, however. Plus, of course, the user still has to make their way over to their phone in order to take the call.

According to Guangli, one charge of the module's lithium battery should be good for over 10 hours of runtime.
