Android-based eyewear woos runners and cyclists

Apr 16, 2015 — by Eric Brown 2,085 views

Recon has shipped its Android-based “Jet” eyewear for $699. The sports-focused Jet integrates a WQVGA display, 720p camera, Bluetooth, WiFi, ANT+, and GPS.


Recon Instruments announced some basic specs and photos of the Recon Jet back in Nov. 2013 when it announced its $399 Snow2 heads-up display (HUD) designed to fit inside a pair of ski goggles. The much delayed sportswear computer runs essentially the same Android-based ReconOS 4 firmware as the Snow2. The Jet offers an “open platform and SDK” for app development, and uses the Snow2’s Recon Engage community site for uploading photos and videos and downloading apps.


The current Jet feature set is designed for runners and cyclists. However, applications under development are tailoring the experience for recreational sailing, performance yacht racing, shooting, and private aviation, says Recon.

People wear all sorts of goofy-looking gear when they exercise and play sports, so the public may well be more forgiving of the Recon Jet than it was with the arguably less obtrusive looking Google Glass eyewear. The Jet eyewear has been under development for seven years, an even longer gestation period than with Glass, sales of which were halted in February. (Google is now working on a new version with eye-tracking technology, according to 9to5Google.)

The chief purpose of Recon Jet is to display performance metrics such as speed/pace, distance, duration, and ascent/descent while cycling and running. The device can connect with other fitness devices that have external ANT+ or Bluetooth Smart (Bluetooth Low Energy) sensors to report metrics like heart rate, power, or cadence. Bluetooth also connects you to your smartphone, sending you caller ID, SMS alerts, and social media notifications.

WiFi and GPS are also included. Whenever in WiFi range, you can upload your videos, images, and stats to Recon Engage, as well as data tracking services including Strava, Training Peaks, and MapMyFitness.

The metrics and notifications are shown in a high-contrast, 16:9 WQVGA display located under the right eye that appears like a 30-inch HD display at a distance of seven feet. An IR receiver notices when you glance down or back up, and turns off the display when you look away, thereby saving on power and minimizing distractions, says Recon.

The display is driven by a dual-core, 1GHz CPU, but it appears to be a different one than the similar SoC listed for the Snow2, as there is no mention of the ski eyewear’s PowerVR GPU. The Jet offers the same 1GB of RAM as the Snow2, but you four times the flash, at 8GB.

You control the device with an optical touchpad on the side of the glasses, as well as a rocker button underneath the right sidepiece. There’s also a 720p camera, speakers, dual microphones, multiple sensors, and a micro-USB port that can charge the swappable, 4-hour Li-Ion battery.

The only major difference we can see compared to the Nov. 2013 prototype is that the weight has grown from 60 grams to about 85. The electronics are distributed across the eyewear, ensuring the device is well-balanced during long workouts, says Recon. The device is said to be resistant to both water and dust, but no IP rating was supplied.

There is currently no prescription glasses support or support for left-eye dominant customers. However, according to an Engadget hands-on by Daniel Cooper, the eyewear fits fine over prescription glasses. Cooper seemed impressed with the engineering, but less so with the styling, weight, and price. His admittedly rushed conclusion from the brief hands-on: cyclists will probably be more inclined to pay the $699 than runners, who can more easily glance at a cheaper smartwatch or phone.

The Recon Jet joins a growing collection of hands-free eyewear and headgear computers, most of which run Android or Linux. Many are devoted to industrial and field service where fashion is even more forgiving than on the track or ski slopes. A Linux-based product called Tobii Pro Glasses 2 designed for market research was this week updated with a 50Hz sampling rate and newly enabled sensors.
