The Touch-controllers for the Oculus Rift vr-glasses will be delayed and released much later, actually the second half of 2016 is not what Oculus states.

The delay is need to further improve on the controllers:

"On the path to perfecting Touch, we’ve decided that we need more time before release, and we’ll now be shipping Touch in the second half of 2016. Pre-orders will open a few months prior to launch.

Rift remains on schedule to ship in Q1 with pre-orders launching very soon.

On Touch hardware, we’ve made significant advances in ergonomics, and we’re implementing many changes that make Touch even more comfortable, reliable, and natural. We’re also implementing changes that improve hand pose recognition.

We’re also outputting larger numbers of pre-production runs, which means we can get a lot more Touch hardware in the hands of developers who need it. There will be a huge amount of ground-breaking new content launching alongside Touch. We shared a handful of early previews at Oculus Connect 2 in September, but we can’t wait to show you what’s coming next."

Oculus announced the Touch-controllers back in June. The controllers are based on tracking technology, vibrating motors with haoptic feedback, thumb-joysticks, two button and trigger for you finger.
