I've had a leap controller on order for a while - only another month to go. I expect we'll eventually see a whole range of new user interface tools gaining traction with the challenge of how to each one effectively and how to combine them to use them synergistically.

Perhaps the leap controller could be worn around your neck and used as a UI augment to Google's Glass or for projected HUD displays. Touch interfaces are ok when you have the physical device in the close proximity but wouldn't it be better if you can just gesture to the computing device if you are, say, standing in the kitchen or driving your car..

On a desktop computer if you're panning across a spreadsheet or a multi-display desktop the longer sweep of your arm may be more convenient than repeated mouse swipes in a constrained space. Or for pointing to what window you use to focus on. Or for controlling a web cam during a video conference.

Emotiv's Epoch BCI (eeg based) is another one to watch although wait for them to come out with the version that uses dry sensors (I was hoping they'd consider adding tDCS support to allow for increased intelligent/memory since they've got the headset and leads in place but they didn't want to get into the medical device/liability issues).

Anybody have any ideas on whether conductive carbon-nanotube based thread will have a significant impact on wearable electronics? Perhaps for data gloves? There were some articles a couple of months ago about a breakthrough that will allow for industrial scale production of such thread.

Leap has been getting some bad press about their software's usability, but recently Elon Musk demonstrated the best application:

Combined with voice commands it could be really easy to develop this for mainstream use, especially for goggled interface.

Shades of "The Genesis Machine".

Then there is DisplAir --

and others.

The turbulence jitter is somewhat annoying. This screams for truly laminar flow.

Or, an active-optics approach that projects an invisible (IR or UV) "sense" grid and corrects visible point position in real time. Doable.

Just saw it advertised at the washington Times. It's cheap:

With what am I supposed to be impressed in that video? It looks like just zooming, rotating and other stuff done at much slower speed than mouse and hot keys.

No carpal tunnel, arthritis, etc.

Later, the ability to interact directly with a projected image (once the display technology catches up), a la Tony Stark.

Ultimately, tactile feedback included.

My best guess has been superceded by the relentless March of Progress.

"Ultrahaptics" integrated with a Leap Motion controller:

Sounds promising, as long as the ultrasound has no long-term ill effects on the human body.

Now, if an ultrasound field could also be used to hold "dry" steam droplets in place, or at least confine their motion to a non-rippling projection surface, then the turbulence problem would also be solved.

Getting better. No perceptible delay is always a good thing for user interfaces. Don't make people wait on computers.

Too bad I can't buy stock.

Conjecture -
The non-LOS points are remembered when they do come into view, and then virtualized when again out of view. Hence a reason to model finger joints, joint angles and overall hand geometry.

If anybody here has a Leap with a point-cloud app, if you keep your hands palms-down and just translate them after power-up across the upper range of the detection region, are points on the backs of your hands still shown?
