Heads-up display: Google Glass is a proof of concept and then there is https://www.magicleap.com
Virtual keyboard and pointer: https://www.myo.com/
Speech-to-text interface: Not that useful for mobile, imho. Seems to work at home (Alexa, etc).
Heads-up display: Google Glass was weird. The focus was on "gargoyle" stuff, not on AR. The display needs to integrate with and enhance reality. Not a small area in a corner.
Speech-to-text interface: That works very well for me. For short messages, anyway. Proofreading and editing is essential, however. To avoid embarrassment and confusion.
