Control app with eyes

VIDEO The AR hack, Eye Nav, is fairly impressive, too.

The feature was announced on Wednesday as one the features Netflix tested during its Fall 2018 Hack Day.

But Denison and other Samsung executives say display technology has improved to the point where it's now possible to fuse an ultra-thin screen onto the foldable design.

VIDEO A third hack doesn’t involve Netflix, but rather the productivity software Slack, used by Netflix employees.

Netflix’s internal hackathons have consistently produced fun and often silly hacks, from that “Netflixtendo” hack a few years ago that let you run Netflix on the original NES to the more recent “audiobook mode” that turned Netflix series into old-school radio shows by way of Audio Descriptions.

The "hack" lets you navigate the Netflix app, select a title and start watching all by using eye movements.

Less clear are the details about how a foldable phone like this one will stack up to rigid-phone competitors, including Samsung's existing line of Galaxy phones.

Another hack from Netflix Hack Day lets viewers skip straight to the action scenes of certain movies.

As at many companies, hack days give Netflix's engineers a chance to experiment with new ideas that may or may not be adopted later.

Netflix is testing ways to navigate its app with your face.

As part of the company's (mostly) biannual Hack Day, Netflix showed off a new feature called Eye Nav, an accessibility feature that lets you control its iOS app with different facial movements, using Apple's Face ID, and built using ARKit.

This year’s hackathon doesn’t disappoint either, with new hacks that are both as goofy and interesting as in years past, including an AR and Face ID-powered hack that lets you navigate Netflix with just your eyes, another designed for “Sharknado” fans and more.

Flex Zone Samsung has been trying to pull off a flexible phone since at least 2011, when it first showed off a dual-screen handset with a creaseless display.

But the larger goal of Netflix’s hackathon, as you can probably tell, isn’t necessarily about creating features that will later be productized (although, c’mon…Jump to Shark!)
