Eye tracking technology
Samsung brought out eye-tracking technology to help users scroll up and down pages. Apple could take a similar approach with a high-resolution FaceTime camera (more on that in the next slide). The capability already exists loosely in third-party software form, and would be a benefit to heavy email or ebook reading users.

A better front-facing FaceTime camera
We've all taken a selfie in our time, no more so than on our iPhones. But the front-facing FaceTime camera is poor at best — particularly in low-light conditions — even if it's the better camera on the market. From selfies to video calling, Apple could set the trend for high-definition video calling if it included a 3- or 4-megapixel camera in the front.
Faster transfers over Lightning connections
Apple's Lightning connection is faster than most other cables and connectors on the market, allowing a device to perform a full sync in a matter of seconds. But could it be faster? Especially if we see more storage, such as a 128GB iPhone, the connector will have to be significantly faster to keep up-to-speed with our increasing demand for space and content.
