One difficulty with the Dodocase VR is that one has to hold them in their hand to use it (even with both hands, ideally). Sometimes that's not desirable, and a hands-free head mount is required. It's possible to add some elastic head straps or suchlike, but our hackerspace members wanted to recycle the boxes the kits came in for maximum greenness. Here are the results of those efforts: a full-head mounted and an ear-mount VR kit.
- Some Dodocase VR kits, assembled
- The kits packaging material
- Cardboard knife
- Sticky tape
These ingredients can be very easily adjusted to what's actually at hand when making these mounts.
Step 1: Full Head Mount
For a full head mount, or "VR helmet" you might need up to 3 pieces of the Dodocase VR kit's packaging material to be completely recycled.
First attach two of the packaging boards to each other in a way that the the fold will go to the two side of the head, and the assembly is in the front of the face. Tried to use the stickers remaining from the kit's lens assembly, but those are not strong enough, better to use proper sticky tape.
Attach one more board that will serve as the top of the helmet, and secure it on the top of the front and the sides.
Cut a hole in the middle of the front, measuring it out where the user's eye level is, somewhere above the central line of the front. Do a use test. If it's lower than suitable that's not a problem, can pad the helmet's top. The cutout should be tight for the kit so it does not fall out. Then do not need to use any adhesive on the kit, and can be removed to be used without the helmet.
The back of the helmet is held together with a couple of the rubber bands that come with the kit. Tie them together, and to the two side-flaps through some holes on the side. It will keep the back of the head in place. They are not very strong rubber bands, so might break during this operation.
You are ready to use the hands-free VR kit! It provides better protection from ambient light as well, and can use it for other experimentations, like we did prototyping printed 3D effects, and other projects.
Step 2: Ear Mount
If you don't have that many kit assemblies, can try to go with a simpler setup.Two flat pieces of the assembly are attached to the kit's two sides, taped down, and slots are cut out for the ears at the appropriate places (test them on the target user).
This assembly is simpler, but has the disadvantage that your button might be covered, and more importantly that it is not very stable, your ears might release it, and you don't want your phone to be dropped.
Maybe the most useful situation is using it on a reclining chair, and with non-angle-sensitive and non-interactive content. YMMV.
