Re: The Leap Motion Controller Now Supports Linux
#32Does anyone know why the Leap preorder page specifies a Phenom II or an i3/i5/i7 processor in the fine-print hardware requirements? Is it for a particular chip feature? Or is CPU overhead going to be a big issue?
Possibly for sse3, which i think was first in phenom ii for amd. For intel its likely just listing everything but atom
but I have an Athlon II 640 which supports SSE -SSE4A?
They also said that CPU overhead would be low.

#33Does anyone have any real-world experience using the Leap? It looks cool as hell but I'm hearing rumors that it doesn't work well in the presence of halogen / incandescent bulbs or direct sunlight. If I have to carefully control the lighting to be able to use it, that's a dealbreaker for me.
Yes, I have a dev kit and have played around with a it a bunch. I'm very impressed with the low latency and high framerate (~110 fps via usb 2, rumored to go higher for usb 3.0). Latency is unquantified but barely perceptible even when moving quite quickly. The potential performance issue is with dropouts and interference. It's pretty easy to have detected fingers drop in and out, mostly due to fingers occluding each…
had the same issues with the dev-kit, hope they implement some sort of a multi-device mode in the future which gets rid of these occlusions caused by having only one point of view to the scene (you can do only so much with modeling, but that would be a start). The interaction experience for actual hand-gestures is, due to these limitations (sweet-spot-size, occlusion and hand orientation) far from what could be considered intuitive. Single tip input with chopsticks is the only mode that works immediately as one would expect.

#34D: huh, kinda looks cool but I think I'd get tired of holding my hands up all day :P D: s'what keyboards, palm rests and elbow rests are for S: yeah, i hear you S: i played around with it for about 20 minutes and my arm was aching So yeah. this is me being skeptical
You know what? A year ago, I would have shared the exact same scepticism. Now, I have an infant daughter who likes nothing more than being carried around, which has exponentially increased the number of activities I do with one hand, standing up. Being able to have a soundless controller that you don't need to pick up or fiddle around with in a way that disturbs a tiny human sleeping on your other arm sounds like abs…
As the owner of a sizable 2.5 y/o I agree.
Also by the time you cary your Bundles of Love around day-to-day, your arm strength for this type of HCI goes up substantially.

#35Triggered a preorder... Without a doubt I'm going to use a product less if I have to boot into Windows...
It's comments like this that reminds me why I would never use Linux on my desktop.
Because you'll like it so much that you won't want to boot to an OS you like less to use some stuff?
I guess that makes sense, it's also why I don't go to the amazing restaurant nearby but go to the shitty one. Only the shitty restaurant has tacos, and sometimes I want tacos.

I just went to the leap dev meetup in nyc, (i also dev for leap). My feeling is that its a great UI instrument, for UI focused applications. What do i mean by that? Well, think of museums, aquariums, jobs such as architecture, perhaps autocad. Jobs/tasks where it would be way more fun and efficient to do the action with your hands.

#37Earlier quoted context omitted.
Also, specifically Ubuntu - it depends on a higher version of libc6 than is available in everything up to and including unstable in Debian repositories, it's only available in experimental.
Also known as Steam syndrome. Does this trend worry anyone else? Limiting usage to one distro can't be a good thing.
It really worries me, especially as it's not just differently structured distros like arch that are out in the cold, but debian, which Ubunutu is derived from.

Well, I guess if you're that much of a diehard, just check out this project instead: http://www.duo3d.com/ they're planning on fully opensourcing everything. If you're annoyed because of the apparent dependency on ubuntu, note that I got things working on gentoo without much issue: http://www.keyboardmods.com/2013/03/leap-motion-in-gentoo-li...
Re: The Leap Motion Controller Now Supports Linux
#39Specifically Ubuntu 12.04 LTS, 12.10, or newer; the SDK is distributed as a .deb file
I got it working just fine on gentoo, see the walkthrough here: http://www.keyboardmods.com/2013/03/leap-motion-in-gentoo-li...
wasn't that hard.

I can say that even with this latest release, CPU usage on my fairly beefy i7 system is ~ 40% on one core.
