3.6. See-through function
MOVERIO Pro is a device that uses projection technology.
Projection is displayed by reflecting light through an Active Matrix LCD panel into a light-guided
panel. It is possible to create a half-mirror version (whereby not all the pixels are needed)
allowing images to be arranged over a real-life scene giving a sense of transparency, and creating
a more vivid augmented reality experience.
To create this transparent background effect, so visual elements (text, graphics…) stand out
vividly, the background will need to be set to black when drawing on the projection, so you
display the target section overlapping with the actual images.
(In this situation, we recommend that you do not use the shade.)
The following steps allow you to create this AR effect using the see-through function.
1) Execute full screen support.
To reduce the feeling of being in a screen, remove everything except for the necessary image
(status bar etc…).
2) Make the background black.
Make everything black except for the object you want to display.
In theory, the black section should keep out external light.
