Amazon's new 3-D smartphone's Omron's Okao Vision face sensing technology will track user's eye movement when released June 18.

According to Tech Crunch, this will use a total of six cameras. The online retailer did not release details about how it would detect the way a person moves their eyes until Friday. The company first shed light on the phone's launch Thursday.

A principal analyst at Enderle Group told Marketwatch that the phone's 3-D display allows consumers to easily view the device's many apps.

"A 3-D screen will allow you to basically have multiple virtual panels you can see into the device," Rob Enderle said. "You could get a ton more space to put stuff on, and then rotate the box to sharpen the focus on the one item you want." The phone's 720 pixel screen measures 4.7 inches. It also has a Qualcomm Snapdragon processor and two gigabytes of RAM Tech Crunch reported.  

Amazon wants to see its 3-D eye-tracking concept expand. It hopes developers show interest in Omron Okao and make other apps from it. According to Tech Crunch, Omron can detect information about a consumer's face and its characteristics. The person's gender, age, and the ethnicity is also analyzed. Omron Okao's Android and Fire operating system will have two installed gestures for users to access.

According to The Wall Street Journal, Amazon plans to boost sales by analyzing data it collects about where consumers use their smartphones. The company will also tally which apps users download. These include programs for videos, household products and e-books.

The online retailer told consumers about the launch via their Twitter account.

"Join Amazon's founder Jeff Bezos for our launch event on June 18 in Seattle. Request an invite," the post said. Click here for more information.
