Tag: Focus

Have 20/20 vision? That must be nice. My eyes are awful, and if they were any worse I’d be wearing dual eye patches right now. But here to push the envelope in vision correction is University of Utah electrical engineering professor Carlos Mastrangelo and Ph.D.

It’s something pretty basic that all photographers learn – focus is everything, and when you don’t have it in your photos, you might as well start over. That’s why I find this new technology from Lytro interesting.

These ceiling mounted speakers from Holosonic Research precisely direct a beam of sound so it can only be heard if you’re standing directly inside the focused area they project. Their square Audio Spotlight speakers easily mount in place of standard 2′ x 2′ ceiling tiles and project a perfectly focused tunnel of sound towards the people standing beneath them.
