This is a really simple but useful addition to cardboard kits that don't have the magnetic attachment to simulate a touch or smartphones that do not react to a change in magnetic flux.
All you need is:
- Your assembled cardboard VR headset
- Copper Tape
Step 1: Size Up Your Phone
Observe your phone's position in the VR headset and look for a spot which is reactive to touch but will not obstruct your view when you peer into the headsets.
Step 2: Place the Copper Tape
With your phone securely housed in the headset, place one end of your strip of copper tape on your chosen spot as in the previous step. Wrap it around to the side of your phone so it is easily accessible when holding the headset up.
TIP: Map out your preferred area on the outside of your kit in advance with copper tape to see if you'll be comfortable dedicating that spot as a button. It will be quite easy connecting it to your phone with the copper tape from here.
Step 3: Now Try It Out!
You can test it's responsiveness using flappy bird before you get into any VR apps. It should work like a charm.
