How dangerous is it to constantly check your phone while navigating?

According to data from the U.S. National Safety Council, the accident rate caused by looking at phones while walking has risen by 35% over the past five years. Meanwhile, using a phone for navigation while cycling or driving increases reaction time by an average of 0.8 seconds—equivalent to traveling an additional 6.7 meters at a speed of 30 km/h.

We need a way to access navigation information without having to look down or take out our phones.

The “first-person view navigation” feature of AI glasses was created precisely for this purpose.

30-Kilometer Field Test: The Strengths and Weaknesses of AI Glasses Navigation

I wore a pair of AI glasses with AR navigation capabilities (which display directional arrows and distance figures right in front of my eyes) and conducted tests across four different scenarios: city streets, park trails, underground walkways, and large shopping malls. Technical Details + Real-World Experience:

City Streets (10 km): The glasses used bone conduction to prompt, “Turn right in 200 meters,” while a green arrow appeared in the corner of the lens. I didn’t need to look down at my phone once during the entire journey, and my average speed increased by 12% because I didn’t have to slow down to pull out my phone.

Underground Passages/Tunnels (No GPS Signal): The glasses’ built-in six-axis gyroscope and barometer activated “inertial navigation.” During the two minutes without GPS signal, the navigation error was only 5 meters, whereas a smartphone map would have “drifted” off course.

Inside large shopping malls (navigating to specific stores): The glasses require support for indoor Bluetooth beacon positioning. During testing, a particular model of glasses, working in conjunction with the mall’s beacons, successfully guided me to “XX Coffee” on the -1 level, whereas smartphone navigation often displayed “weak GPS” indoors.

Weakness: In direct sunlight, standard light-guide lenses lack sufficient brightness (<1000 nits), making the arrow nearly impossible to see. Only glasses utilizing Micro-LED technology (brightness > 2000 nits) can resolve this issue.

Data Comparison: When using AI glasses for navigation, the number of task switches (from the road to the phone screen) dropped from an average of 23 times per 10 km to 0 times; the subjective safety rating improved from 6.2 to 9.1 (with 10 being the safest).

The 2024 test report by the German ADAC Automobile Club states that smart glasses with AR navigation have a “cognitive load” 57% lower than in-car screens, making them the ideal form of in-car navigation for the future.

Venus Smart Shop's Recommendations

Not all AI glasses are suitable for navigation. You should look for: brightness (≥1500 nits for daytime outdoor use), battery life (≥4 hours of continuous navigation), and inertial navigation support. We recommend the TCL RayNeo X3 (2500 nits brightness, 6-hour battery life) and the Vuzix Shield (designed specifically for industrial navigation).

Safe navigation starts with keeping your eyes up.
