Although researchers have proposed several autostereoscopic displays, the resolution and viewing position is still limited. Furthermore, stereo and multiview technologies rely on the brain to fuse the two disparate images to create the 3D effect. As a result, such systems tend to cause eye strain, fatigue, and headaches after prolonged viewing because users are required to focus on the screen plane (accommodation) but to converge their eyes to a point in space in a different plane (convergence), producing unnatural viewing. Recent advances in digital technology have eliminated some of these human factors, but some intrinsic eye fatigue will always exist with stereoscopic 3D technology.
These facts have motivated researchers to seek alternative means for capturing true 3D content, most notably holography and holoscopic imaging.
Next up: holo TV. That’s totally going to replace the not-so-successful-3D!
