This is a light detection device.We combine the straight and arc surfaces in this small form, which allows you to detect different light. We hope it as precision as a vernier caliper, as elegant as music.Actually it is our entrance to an Augmented reality platform.The platform adopt its light source detection technology rendering live object.The AR objects are embedded into the real world environments, positioning the object at the correct aspect scale to the user and rendering object shadow layers. Automatically sync’s with users wearable device (international patent).It will truly unlocking device AR applications to real world communications.
