Apple continues medical hires, could their ambitions go beyond the iWatch?

Apple has continued hiring of medical experts, nabbing Michael O'Reilly, formerly Chief Medical Officer for Masimo, to work on a number of projects for Apple, possibly including an iWatch. Masimo specializes in medical sensors, and is responsible for the iSpO2, a pulse monitor that connects to your iPhone. Given recent reports about how Apple's rumored iWatch is suppsed to work, using medical sensors to measure pulse, glucose levels, and more, it seems natural that O'Reilly would be bound for that project. However, it looks like he'll actually be working on multiple projects for Apple, accoring to Mark Gurman at 9to5Mac:

This hire, however, is not really breaking news: sources with knowledge of Apple’s work on the iWatch say that O’Reilly actually joined Apple last August. These people also say that he is not solely focused on the iWatch project; instead he is working on a range of projects.

So what could these other projects be? Perhaps improvements to Touch ID, or maybe something for the iPhone 6? What do you think O'Reilly could be working on? Let us know below in the comments.
