With the movie and games industries already working on 3-D content for cinemas and televisions, Jostes believes that the next logical step is the mobile market. The first products featuring the Vikuiti 3-D film have already begun hitting the market in Asia, he says.
However, auto-stereoscopic displays have serious drawbacks, says Armin Schwerdtner, chief scientific officer of SeeReal Technologies in Dresden, Germany, which makes a competing kind of 3-D display. The so-called parallax effect, for instances, occurs when a viewer's head moves and her 3-D perspective is destroyed, which can be nausea-inducing. For this reason, says Schwerdtner, most display companies are still focusing on 3-D techniques that use glasses. "We abandoned [the auto-stereoscopic approach] because we found there were human factors that caused problems," he says.
Jostes argues that most people are used to holding their mobile devices relatively still already. Furthermore, he says, the Vikuiti 3-D approach allows for better resolution and brightness. "And what's nice about it is you can switch between 3-D and 2-D," he says. Displaying identical images on the LCD panel would give both eyes the same 2-D perspective.
Pepy of Alioscopy doubts that 3-D mobile displays will ever be more than a gimmick. "If you want to target the mobile market you have to provide a complete system, you need the capability to take pictures and video in 3D and to send them," he says. "And on a mobile display the depth effect will be very small."
Steven Smith, a 3-D display researcher at De Montfort University in Leicester, UK, disagrees. While the depth perception provided by a mobile device may not be very great, "you don't need a lot of depth cues to make it interesting," he says. "I think 3M's timing might be good."
Glasses-free 3-D television is still a long way from the market.
