Customizable and flexible variant of DIY stereoscopic viewer for smartphones compatible with Google Cardboard and made with commonly available materials and accest to laser cutter. Open-source DIY VR kit was developed in 2016. by Hrvoje Spudić and Damir Prizmić as part of radiona.org educational program.
Our prefabricated kits support smartphones with flowing dimensions:
In case you phone doesn't fit we recommend you modify the design to your requirements and 3d print or laser cut the plastic case.
Both Android an iPhone platforms are supported. It is preferable that smartphone has gyroscope sensor, you can google your phone for specifications to find out. Note also that it can still work without it, but its since gyroscope is the main sensor used for detecting movement it will be mostly useful for looking at static stereoscopic images (3D).

).Interpupillary distance (PD) is distance between the centers of the pupils of the two eyes. This should be adjusted to the face properties of the viewer (normal range for most individuals is between 54 and 74 millimeters). Ask someone to help you measure the distance using ruller. While measuring look at the distant object. Note this number for later viewer calibration.
Use the Google Viewer Profile Generator to define your device's key parameters and generate QR code of your specific viewer, so every Cardboard app will automatically adapt to it. Use VR Calibration for Cardboard (Android only) to discover the parameters. Changes made with this tool are NOT saved anywhere and will NOT affect your smartphone's Cardboard profile directly. Once you are happy with the parameters enter them in Google Viewer Profile Generator page to create a new personalized VR viewer profile. A profile encodes the viewer parameters and ensures that all apps written using the Cardboard SDKs work well on that viewer.

There are many apps for VR smartphone viewers, just search for cardboard

or 360
. Most of the apps can use our custom viewer profile, but “Google VR Services” needs to be installed for that.
