Looking Glass now supports seamless integration with iOS devices, allowing users to connect their Looking Glass Go or 16” displays directly to an iPhone or iPad via USB-C. This capability enables you to run interactive applications for your Looking Glass display using compatible iOS devices, such as the iPhone 15/16 Pro, iPhone 15/16 Pro Max, and iPad Pro (M4).
With this new feature, you can:
Run Looking Glass iOS apps like the Hologram Video app on the Looking Glass Go and 16”
Build and deploy your own iOS applications for Looking Glass using our Unity plugin
Run demo applications demonstrating different use cases with a seamless setup
This opens up exciting new opportunities for developing and showcasing interactive 3D content without the need for a computer, streamlining workflows and expanding creative possibilities.
Looking Glass Go displays can be run via iPhone 15/16 Pro or iPad Pro (M4) devices.
Both power and display signal will be driven by the iOS device via a single USB-C cable. There is no need to connect your Go to a different power source. It will work like a holographic secondary display for your iOS device 🎉
The Looking Glass Go is slightly under the maximum threshold for power draw from iPhones. This may cause the iPhone to warn you that it "Cannot Use Accessory" — you can ignore this warning and select "OK".
To set up your Go device to be able to run iOS devices, follow the user guide to setting up your Go device. Once is it set up and connected to the internet, it will automatically receive an update to the latest firmware version — this is required to be compatible with iOS devices. You can check your firmware version via the Go Mobile App by selecting the settings button on the top right. You must be on firmware v1.0.59 or later.
Note that updates can take several minutes to download and process. If your device fails to update, you can do so manually by following these instructions and can contact our support team for assistance at support@lookingglassfactory.com.
Once your Go device has updated, run the device once in Standalone mode, and then restart the device. This will create a new drive on your device that is required for interfacing with iOS devices.
When your device has restarted, connect your Go to your iPhone or iPad via USB-C cable. The power light indicator should turn blue. Press the power button.
The screen of your Go device should turn on and mirror your iOS device screen.
For best results, you should also set the audio output device to be the iPhone, not the Looking Glass — this will ensure you can hear any sound effects and audio from running apps. To do so:
Pull down from top right corner of your iPhone to expose the menu
Click the button on the top right of the menu
Select "iPhone" from the options
The setup is now complete and you can run our iOS software applications.
Looking Glass 16” displays can be run via iPhone 15/16 Pro, iPhone 15/16 Pro Max, or iPad Pro (M4) devices, but we strongly recommend using an iPad for best performance.
To connect your Looking Glass 16” display, plug both USB-C cables into the device, per the hardware setup guide. The HDMI cable won’t be necessary. Plug the other end of one of the USB-C cables into the power adapter and plug the power adapter into a wall socket. Plug the other USB-C cable into your iOS device. Your Looking Glass display should now turn on and show the iOS device background. The setup is now complete and you can run our iOS software applications.
For optimal usage of the system, there are a few settings that will improve the user experience.
Set your device to extended, not mirror — this will improve the rendering quality of the output in the Hologram Video app and when no app is being run from the iPad
Under "Settings" -> "Display & Brightness" select "Arrangement" and ensure the toggle for "Mirror Display" is off
Set audio output device to be the iPad, not the Looking Glass — this will ensure you can hear any sound effects and audio from running apps
Pull down from top right corner of your iPad to expose the menu
Click the button on the top right of the menu
Select "iPad" from the options
Set the lock screen to activate after 15 minutes — this will mitigate any burn in caused by having a static image run for too long
Under "Settings" -> "Display & Brightness" select "Auto-Lock" and ensure "15 minutes" is selected from the list of options
Ensure low-power mode is disabled
Under "Settings" -> "Battery" make sure the toggle for Low Power Mode is untoggled
We provide a suite of iOS applications for you to use on your Looking Glass devices.
For all applications, you must first select the calibration file for your Looking Glass device. When you run your application, you will be prompted to:
Connect your device via USB-C
Load a calibration file via the file browser. Calibration files are under Locations -> LKG-XXXXXX (your device serial number) -> LKG_calibration -> visual.json. Select the visual.json file
Your calibration is now loaded — applications will store this for future use
Calibrations differ between devices. If you connect your iOS device to a different Looking Glass, you’ll need to reset your calibration. Applications will ask you to confirm the loaded calibration when you start the app. If your device is connected to a new Looking Glass display, be sure to load a new calibration file.
If you’ve asked to not show this prompt again but have connected your device to a new Looking Glass display, you’ll need to change the calibration by selecting Settings (the gear icon) -> Load new calibration. Navigate to the visual.json for your new device and select it.
You can also confirm your calibration is correct using the calibration test image. This can be selected from the popup screen that notifies you which calibration files is being used, which appears once you connect your device or can be accessed by pressing the gear button for settings. The test image should show a red vertical line in front of a blue vertical line in the center of the screen.
If your Looking Glass doesn't have these two superimposed straight lines in the center, you're likely using the wrong calibration. Reload the calibration file to resolve the issue.
Access Hologram Video via the App Store.
This app lets you load and play Cinematic mode video captured from iPhones as well as RGBD videos generated from other services, like Owl3D.
See a full guide to the Hologram Video app here.
We have a suite of demo applications that showcase different use cases for our technology.
Shows scans of historical artifacts, demonstrating a museum use case. Controls to rotate, zoom, and adjust lighting.
This app is distributed via TestFlight. To install it, first install TestFlight to your iOS device. Then, access it here.
Shows a selection of shoes and sneakers, demonstrating a retail use case. Controls to rotate, zoom, and adjust lighting.
A selection of sample quilts. Quilts can be replaced by tapping and holding, which opens the native file browser. Any quilts stored to Files on the iOS device can be loaded by selecting them from the file browser, though they must have the correct naming convention — filename_qs11x6a0.56.png where qs11x6 indicates a quilt with 11 columns and 6 rows, and a0.56 indicates an aspect ratio of 0.56.
Uses the built-in camera in your iOS device to let you become a holographic sloth character, demonstrating a location-based entertainment use case.
A selection of models generated from medical scanning data, demonstrating a medical use case.
In addition to running the Holographic Video Player and demo applications, you can also create your own content via our Unity plugin. Follow our developer guide for more details!
