It’s not every day I get to try out an entirely new type of tech product. Telescope company Unistellar recently gave me the chance to do just that with Envision, the first smart binoculars that can identify mountains and stars. The only things like it on the market are Swarovski’s smart binoculars, but those are triple the price and strictly for birds and wildlife.
At an event near Marseilles, I tried an Envision prototype with the design and most of the functionality of the final product (like several other Unistellar products, the company marketed it on Kickstarter and raised $2.7 million). Some features were a bit rough and it took practice to use the binoculars smoothly. But it’s an interesting amalgam of analog and digital tech that’s bound to be a hit with astronomers and travelers.
The Envision initially came out of a conversation between Unistellar engineers wondering why there were no binoculars with an AR-like digital overlay. They soon found out: It was a huge engineering challenge. Combining all the data into an overlay and getting it to line up with the optical view was particularly vexing. Reducing latency was another problem, so that the digital display wouldn’t lag behind the optical view.

The company eventually came up with a solution it borrowed from AR tech. Envision combines premium lenses with an augmented reality projection system that beams contextual info into the optical path via a bright, high-contrast microdisplay. That overlay only appears in one eye, but your brain transforms it into a complete image.
The Envision binoculars take data from inertial sensors and a compass using custom software to “guarantee precise positioning and low-drift orientation” of the digital display. It then pulls in topographic and cartographic info from a large database and merges it onto an AR overlay based on your location and viewing direction. This information comes from your phone’s internet connection, but the binoculars can be used offline as well if you load specific regions in advance.

I tested a hand-built prototype that lacked the quality control that will happen in full manufacturing. However, the materials, optics and electronics were nearly complete. For daytime testing, I went to the Citadelle de Forcalcquier that offers a panoramic view of mountain ranges in the region. While it was a bit overcast and rainy, distant peaks up to 30 miles away were still visible.
Though a bit heavier than regular binoculars, the Envision was comfortable to hold and use over a period of an hour thanks to the rubberized coating and high-quality plastics. To use the Envision, you set them up as you would any pair of binoculars. They have a diopter adjustment for your specific vision and you can retract the eyecups for use with glasses. There’s a width adjustment to match your eyes and a focusing wheel to sharpen the view.
