USE IT WITH CARE

Built to be seen. Use it responsibly.

HoloGlass is made for parked use. Here’s how to use it with care for the people around you.

THE SHORT VERSION

Park first. Check local rules. Protect visibility.

You decide where, when and how HoloGlass is used. Use it in a way that never distracts other road users.

FIVE RESPONSIBILITIES

Know the rules before you turn it on.

HoloGlass is a display. How you install and use it depends on your car, where you are and what you show.

RECOMMENDED USE

Use while parked

We recommend using HoloGlass while parked: at events, at pop-ups, or on private property where displays are allowed.

YOUR LOCATION

Check your local rules

Check the rules where you live and drive before you turn HoloGlass on: window coverings, outward-facing displays and advertising. Start with your state’s motor vehicle agency (usa.gov lists them all).

Find your motor vehicle agency at usa.gov

VEHICLE VISIBILITY

Keep the views you need

The screen covers its window while it’s in. Your mirrors and cameras need to give you every view the rules require.

DISPLAYED MEDIA

You’re responsible for what shows

Show only photos, music, logos and videos you have the right to use: check copyright.gov to learn how copyright works. Keep it honest, suitable for all ages and fit for a public place.

Learn more at copyright.gov

FREE SPEECH

Free speech has limits

Your window is a public display, seen by people of every age. HoloGlass, the app and the sign maker are neutral tools, like a speaker: we don’t review what you show, so it’s up to you, within the limits of the law. Obscene or sexually explicit content and threats aren’t protected as free speech, and other laws still apply: on harassment, public indecency, disorderly conduct, noise and anything that looks like a police or emergency signal. Check the laws where you are before you show it. Pranos AI, which paints pictures with OpenAI, may turn down some requests for the signs it designs or edits for you. The sign maker’s colors leave out bright red and blue, and it won’t add a GIF that flashes too fast. Nothing else is checked.

BEFORE EVERY USE

A quick safety check.

It only takes a moment, and it helps protect you, your car and everyone nearby.

01

Back seat empty

Back seat empty while HoloGlass is mounted. Before anyone rides in the back, take the HoloGlass unit down. It sits near head height, and in a sudden stop or crash a passenger could hit it. This applies to every mount, including the roof glass.

02

Inspect the mount

Make sure the HoloGlass unit, mount, screen and cables are firmly in place before you power on.

03

Check visibility

From the driver’s seat, check that your mirrors and cameras still show what you need to see.

04

Confirm the location

Park somewhere displays are allowed, and follow local traffic and advertising rules.

05

Review your content

Make sure what you’ll show is suitable for all ages, fits the place and won’t distract traffic.

06

Set the switch

Before you drive, switch the Pranos app to Driving at the top of Now playing, with your phone connected to your HoloGlass.

Parked and Driving

Parked and Driving, built into the Pranos app.

Before you drive, switch the Pranos app to Driving, with your phone connected to your HoloGlass. You set the switch yourself, at the top of Now playing, on each phone you use. It never changes on its own.

The Pranos app’s Now playing screen, set to Parked: the Velvet Orbit Detailing sign plays in the back windshield shape, with the play controls and the playlist below Now playing set to Driving: the play controls are dimmed, the app says what’s on your HoloGlass stays put, and the playlist is below

Your HoloGlass

Parked: videos, photos, GIFs and signs play. Driving: a playing video pauses on the frame it’s on, and a photo or sign stays up.

In Driving, the app holds what’s on your HoloGlass.

Driving: a playing video pauses on the frame it’s on, and a photo or sign stays up. The app won’t play or upload anything new until you switch back to Parked.

  • Switch while your phone is connected to your HoloGlass. If it isn’t, the app can’t hold what’s showing.
  • The switch is on each phone. If more than one phone uses your HoloGlass, set each one to Driving.
  • GIF signs move while the app is set to Parked, and hold still in Driving.
  • New uploads are off until you switch back to Parked. One that’s already sending finishes and waits in your Library or playlist.
  • Pranos AI’s Auto-play is off until you turn it on. In Driving, a new sign waits on its card: switch back to Parked, then tap Play on HoloGlass.
  • When you’re parked, switch back to Parked with your phone connected. A video that was playing plays on from where it paused.

“You can’t upload videos or photos while you drive.”

The Pranos app, if you try to upload in Driving

Stopped in traffic isn’t parked. Keep the app in Driving until you’ve parked. The Driving switch helps, but it doesn’t make a display allowed where local rules say otherwise.

More about the Pranos app ›

What the app does for you.

The Pranos app’s GIFs tab: Paste GIF, From Photos, and the note: No flashing GIFs. Every GIF is checked on your phone first. One that flashes too fast can’t go on a car window.

Our tools and Pranos AI don’t create flashing effects.

Every GIF is checked on your phone before it can go on a sign. Videos you upload aren’t checked, so don’t play ones that flash.

The Pranos app’s Background tab: color choices with no red or blue, and the note: Red and blue are turned off, they can look like emergency lights.

No bright red or blue in sign colors.

The sign maker’s colors leave them out, and Pranos AI doesn’t use them for a sign’s words or background. They can look like emergency lights. Your own photos, videos, GIFs and stickers aren’t changed, so don’t show ones that look like emergency lights.

  • Front Windshield: parked only.

    Roll the screen up and put it away before you drive.

  • Pranos AI declines police look-alikes.

    It’s designed to keep police, emergency and traffic-control wording, like “Police,” “Pull over,” “911” or a “Stop” command, off your sign, and it leaves out emergency emoji.

  • Back seat empty while HoloGlass is mounted.

    Before anyone rides in the back, take the HoloGlass unit down. It sits near head height, and in a sudden stop or crash a passenger could hit it. This applies to every mount, including the roof glass. While it runs, someone sitting there would also block the picture and look into the light.

  • Never mount it where it could block an airbag.

    Check your car’s manual, and look for SRS AIRBAG markings on the pillars and roof edge.

  • Don’t leave it in a hot parked car.

    Don’t leave the HoloGlass mounted or inside a hot parked car; take it with you or store it out of direct sun. Suction cups also lose grip in heat.

  • Check the mount before you drive.

    Press on the mount to make sure it’s firm before you drive.

  • Driving covers what the Pranos app plays.

    It doesn’t control HDMI mirroring or the HoloGlass unit’s other inputs. Whatever you show, the same rules apply: play video only while parked, and follow your local rules.

COMPLETE SAFETY INFORMATION

Read the full operating guidance.

HoloGlass is an aftermarket display for your car: a screen made for one window, lit from inside the car by the HoloGlass unit. This is how we ask you to use it. It’s general guidance, not legal advice.

1. Parked and Driving

Play video only while parked. Stopped in traffic isn’t parked. Before you drive, switch the Pranos app to Driving, with your phone connected to your HoloGlass. A playing video pauses on the frame it’s on, and a photo or sign stays up. You set the switch yourself, on each phone you use. Driving covers what the Pranos app plays. It doesn’t control HDMI mirroring or the HoloGlass unit’s other inputs. And it doesn’t make a display allowed where local rules say otherwise.

2. Visibility

Many cars keep the views a driver needs through side mirrors or a rear camera, but window and visibility rules differ. Take the screen out whenever the rules call for a clear window.

3. Your content

Use only photos, logos and videos you have the right to show. Using HoloGlass for a business? Local sign and advertising rules may apply too. To learn more, read the U.S. Copyright Office’s copyright basics and the U.S. Patent and Trademark Office’s trademark basics.

What you show is public. People of every age can see your window, and hear it if you play sound. Free speech has limits: obscene or sexually explicit material and threats aren’t protected as free speech. Other laws still apply too, on harassment, public indecency, disorderly conduct, noise, what children can be shown, and anything that could be mistaken for a police or emergency signal. Keep what you show suitable for all ages, keep any sound low, and never show anything that targets or frightens a person.

Pranos AI may turn down some of this when it designs or edits a sign for you, and the sign maker’s colors leave out bright red and blue. Beyond that, you’re responsible for everything your HoloGlass shows, including your own photos and videos and anything you screen mirror. To learn more, read the U.S. Courts’ What Does Free Speech Mean?.

4. Local rules

Rules can differ by state, county and city, and they change. Your state’s motor vehicle agency or your city can tell you what applies to you.

Every order is covered by our Terms and Conditions. Please read them before you use HoloGlass.

6. Our part, and yours

We build our tools with care, but they don’t replace your judgment or local rules. Pranos isn’t responsible for improper installation, misuse or unlawful use.

GOOD TO KNOW

Quick answers.

Can I keep HoloGlass on while I drive?

Not with video: play video only while parked. Before you drive, switch the Pranos app to Driving. Some places restrict any display while the car moves, even a still image. Check your local rules, and turn HoloGlass off where it isn’t allowed.

Does Pranos control what is displayed?

No. You choose what HoloGlass shows, and Pranos doesn’t review your photos, videos or signs before they play. Pranos AI may turn down some requests for the signs it designs or edits for you, such as police look-alikes. The sign maker’s colors leave out bright red and blue, and it won’t add a GIF that flashes too fast. You decide what goes on your window, within the limits of the law.

Is the screen transparent?

No. The screen is opaque, for a brighter image. Take it out when you’re not using HoloGlass.
