You can now use the trackpad as a multi-touch area for the app. Use trackpad as multi-touch area: press and hold the option key ⌥.Scroll: drag from the position of the mouse pointer.Arrow keys: swipe from the center of the window.Space bar: tap in the center of the window.It's pretty much down to the minimum of what you can do with a computer - the capture device still has to buffer a frame, transmit it to the computer, which copies it into RAM, then blits it to video RAM, where it waits for the next vertical refresh.Īll that said, the human finger doesn't travel all that fast, so for a HID application like this, you could probably get the latency way down by extrapolating the near-future position of the finger, much like iPadOS does with Pencil. There's still some latency, but it's better than a webcam. The alternative that usually gets used in productions with a moderate budget is a hardware camera with HDMI or SDI output into a Blackmagic capture device. It's better than it used to be, when webcams were DV over Firewire, but it's still enough that webcams are generally a poor choice for latency-sensitive situations like live performance. This is as much as possible what the Camera cue in QLab does (I'm the lead video developer), and there most definitely is perceived latency. But the judges are meant to operate as experts, and an expert should have (some) ability to discern bullshit from something real. There’s nothing wrong with people trying to game the competition, its a natural function of competing.

an idea I’d seen repeatedly in recent news cycles because some NGO in India was doing it for the last three years.įive minutes of googling would have discovered this, but instead we simply ignored the competition since.Īttending itself was valuable, along with the half-attempt at winning - we clarified the project and ideas, and had an excuse to clean things up - so it would have been a good exercise to do yearly (and probably for the other projects involved), and the competition was healthy.īut it just takes an incompetent judge to spoil the whole thing. Instead I lost to the girl with the contentless idea for edible spoons for developing countries. I had a similar experience in my university - some kind of business project idea competition we submitted my lab’s current project, and there were other interesting projects involved who I would have been happy to lose to. The problem I think is that judges themselves are incompetent/careless - when you promote a “bad” winner, you just discourage everyone from trying, because they realize there is no value to this kind of promotion its bullshit. However, you do want to show off the more interesting/higher quality projects, to encourage further work, and get the whole thing jiving (people enjoy competition it oils the machines) Making the overlay merely annoying, rather than intolerable.īut when it all works, yeah, magical. So always showing what gestures are currently available, and what they do, should become feasible.Įven on a generic laptop screen, DIYed for 3D, it seems you might put such secondary information semitransparently above the screen plane.

And a key impact of VR/AR is having more and cheaper UI real estate to work with.

I fuzzily recall some old system (Lisp Machine?) as having a status bar with a little picture of a mouse, and telling what its buttons would do if pressed. > Gestural stuff is nice when it's transparent and guess-able. And the device is perched on a stick in front of your face. When the poses don't have a lot of occlusion. My fuzzy impression is it's not quite good enough for surface touch events, but it's ok-ish for pose and gestures. But it has apis, so you can export the data. And it's Windows-only (the older and even cruftier version supporting linux, doesn't do background rejection, and so can't be used pointing down at a keyboard). Leap Motion has finally been acquired, so the future of the product is unclear. With more sticks to protect the usb sockets from the cables. And eventually punted, using the bare webcam only for head tracking, and adding usb cameras on sticks perched on the laptop screen. I tried doing this with the internal webcam, using a clip-on fisheye lens, and mirrors. on a laptop, tracking space above the keyboard
