Taking a dive into VR or augmented reality — once, dreamed-of science fiction — is not only possible for the average consumer, but crafting those experiences is as well! Hackaday.io user [kvtoet]’s HandHolo is a homebrew method to cut your teeth on peeking into a virtual world.
This project requires a smartphone running Android Oreo as its backbone, a Bluetooth mouse, a piece of cardboard and a small mirror or highly reflective surface. The phone is slotted into the cardboard housing — prototype with what you have! — above the mouse, and the mirror angled opposite the screen reflects the image back to the user as they explore the virtual scene.
Within Unity, [kvtoet]’s used a few scripts that access phone functions — namely the gyroscope, which is synchronised to the mouse’s movements. That movement is translated into exploration of the virtual space built in Unity and projected onto the portal-like mirror. Check it out!
