this cheap ($3.78 on dealextreme) bluetooth selfie camera trigger with two buttons i picked up when backpacking around thailand. using an android app called keyboard helper demo and the instructions to remap the buttons to keys here http://www.barbatricks.com/en/android-en/remap-ab-shutter-3-selfie-remote/
i’m attempting to create a handheld remote for google vr (formerly cardboard) unity apps. in this photo i have the device paired, the larger button keycode 115 remapped to the w key where i hopefully should be able to use it for input in unity to control a modified headset gaze pointer script to trigger a teleport. maybe bring up a menu screen with the second button.
