There's an Oculus Rift forum post that has a link to hand tracking with the Structure Sensor.
The depth sensing portable Structure Sensor is 95 grams and $380 (Kickstarter).
There's noticeable latency in the hand tracking, but a post talks about possible low latency for static objects by using a previous map.
Assuming you stay within a certain space, would premapping with something like the Structure Sensor or Project Tango contribute the most to the stability of virtual objects that Hololens testers experienced? (objects stick to their intended position as you move):

that objects stayed stable when you move your head
17:43
well hold on a sec it is excellent
17:47
at keeping orientation for sure I looked around and something with an absurd and

17:52
I looked around the same thing was there again I if they're mob rock on the

surface of mars
17:56
or a table covered with you know i i
17:59
toy castle at minecraft made all these tiny little minecraft building blocks
18:03
it would always be exactly where I thought it would be but I had to turn my
18:07
head all over the place cuz the field if the US
18:10
tiny it's like this little I somebody's described it as a sixteen by nine TP
18:15
floating maybe seven to eight feet and Franny
18:18
you're looking through this little narrow slice ever went out about this
18:22
big around in my view
18:24
trying to see mars this much at a time
18:27
and wherever you look is like oh that's exactly where I thought it would be
18:30
but its tunnel vision it's like you're looking through a pair of binoculars or

Or is good real-time tracking necessary for the virtual objects to stay attached to their positions.
