Video: Making the Leap to 3D Motion Control
6/8/2012

The Leap accurately senses the individual movements of all 10 of a user's fingers and tracks objects like a pen, enabling a 3D workspace that recognizes intuitive gestures.   (Source: Leap Motion)

Beth, the video did not show anything beyond what you could do with the Kinect.  It would be interesting to see someone trying to do a real CAD drawing with this device. 

 

CAD has always pioneered input devices.  Frankly, paper drawing required lots of specialized equipment as well.

I was impressed.  I is like taking the big screen Hollywood to the little desktop screen. 

However, I am not sure how to integrate it into my CAD package.  I am not sure how it would be that beneficial in actual drawing conditions, as the sensitivity may not handle changing a few tenths of a degree or mm. 

But I liked it!

I hear what you both are saying about there not being a direct link to CAD at this time. But I think that's the operative words--at this time. I think there's a lot in this device that portends how input devices will evolve incorporating many of the gestures and capabilities that are becoming commonplace on our personal devices. Perhaps they'll call it the "consumerization of CAD." In any event, it's all about this company convincing CAD and design tool vendors to leverage their toolkit to take advantage of the new interaction paradigm. But this device, the Kinect, and what we see on the gaming front are no doubt, going to heavily influence CAD and design tool development moving forward.

Lots of Other Motion Control Apps

What a great idea. I hope they work with Macs. It's not typing that I find wearing so much as all the touch-pad/mousing for web surfing. Aside from computer users, the other application possibility that comes to my mind is robot control. If this UI can interpret human movements, why can't it be adapted to do the same with robots? I've been wondering about gesture control/interpretation for robots that since the Kinect debuted. So far, I've seen research where a Kinect tells a robot about its environment

but what about the other direction?

Also, you better not have bad or painful joints or arthritis if you want to control the software...

Gaming trickle-down

This is amazingly cool. It's yet another example of how gaming leads the way in electronics. For years, graphics chips have trickled down from gaming to less expensive products, giving us applications such as 3D navigation. Who says gaming is for kids?

There's also the risk of unintentional consequences.  How many laptop users have brushed the touchpad and sent their cursor elsewhere strewing their typing in several locations?

The article says Leap will track all ten fingers.  No scratching while working!  And I wonder what finger gesture will mean "CANCEL / Forget about it"?

In all seriousness, gestures can be quite difficult compared to holding something tangible, with a small amount of weight.  This was compared to Kinect - I found Wii bowling to be more realistic with the minimal amount of the Wii controller in my hand compared to the similar game in Xbox with Kinect.

Gesture interpretation for robot movements--now that's a cool idea and one I'm sure has to be well underway in research labs. I don't think gesture movements are that unfamiliar to users any more. Between the new generation of smart phones (not just Apple) and other commonplace electronic devices, more and more users are getting familiar. And for those up and coming engineers born and breed on consoles like the Xbox and Wii, this kind of interaction will be expected.

vaporware?

"Here's the best news. The Leap is pretty cheap. As it is not available yet, those interested in taking it for a spin can pre-order the device for $69.99." Turns out that you pre-order and get charged when the item is shipped - projected for early 2013!!!!

Am I the only one who smells vaporware?

NEW??? 3D motion control for industrial robots??
William K.   6/11/2012 12:10:17 PM

The robot makers long ago eliminated the error prone method of sensing what the programmer intended as a rototic motion. The result was direct control of all six axis. Why in the worl waste time and effort in making it easy for the untalented, untrained, and unskilled person to program a robot for some task? Or is this an effort to put robots in every household, in the name of increased profits? There are thousands of folks who are totally unable to think out the results of their actions, and what we rally do not need is those folks programming robots, which can move much faster than people, but who are also capable of making the same wrong move repeatedly. What the developers are doing is attempting to blast the lid off of Pandora's Box, again.
