Hard Case: Where’s My Multi-Touch?
Using a mouse with a 24 megapixel display is problematic. Loyd wants another solution to manage all those displays.
So AMD’s ATI graphics division has got something in the works that supports up to six monitors.
If you’ve ever navigated even two displays with a mouse, you may realize something: multiple, high-resolution displays may be outstripping the mouse’s capability as a primary user interface tool. Now toss in six 30-inch monitors – 24 whopping megapixels in all – and you’ve got a real problem. Even if you drop that to six more affordable 1920x1080 displays, that’s still over 12 megapixels you need to navigate. Just visually tracking the mouse cursor becomes problematic.
Still, it's a setup I’d love to have.
What’s needed for huge pixel-count displays is multi-touch. Windows 7 now incorporates an actually useful multi-touch display capability, but it’s currently relegated to all-in-one PCs with multi-touch, a handful of laptops, and the expensive (at $12,500 a pop) Microsoft Surface.
Still, multi-touch isn’t perfect. If you’re a heavy Photoshop user, you need a high degree of precision in selection, sometimes down to the pixel level. For that, a high DPI mouse is indispensible. What would be better in a system with three to six displays would be a combination of multi-touch and a good mouse.
But affordable multi-touch monitors are nowhere to be found. The only desktop display I could find was one by Albatron that was announced back in 2007. But just try actually buying one – you can’t.
You can find multi-touch in all-in-one desktops, like HP’s TouchSmart PCs. Recently, Lenovo announced a Thinkpad model, the T400s, with a multi-touch displays. A touch sensitive display (that’s not just a tablet PC) makes sense – it’s more useful for normal office work than the touch pads that grace most laptops today.
So where are the multi-touch monitors for desktop PCs? Other than the vaporware Albatron announcement, I haven’t seen any major LCD manufacturer announce multi-touch displays. You’d need the proper connectivity, of course, but an additional USB connection should cover that. Given the additional electronics needed for the touch-sensitive interface, a multi-touch display would cost more – but it wouldn’t have to be a huge cost uplift. I’d pay $50 more for a multi-touch 24-inch display, for example.
If large scale display technologies, like AMD’s Eyefinity, are going to be successful, we need to move beyond mouse and keyboard. If multi-touch monitors aren’t available, there’s another route: gesture recognition.
In fact, incorporating gesture recognition would be easy in a 3-display setup. The reason is the increasing number of desktop displays with built-in webcams. Imagine a 3-display setup. The center display might be something large, like a 30-incher. The two “surround” displays could be 24-inch units, each with a built-in webcam. They could be mounted in portrait or landscape mode. The outboard units with the webcam need software that could “read” gestures from the user. Given the separation of the webcams, you could imagine software that could interpret gestures in 3D space, allowing for a larger variety of gestures.
Four or six displays in a flatter arrangement wouldn’t be harder, since you could still have enough separation between webcams for this to work correctly.
Of course, Microsoft’s already done something like this – it’s called Project Natal. Alas, it’s the Xbox group that’s doing this, not the Windows group. If Microsoft could get the Windows group to do a webcam-based gesture recognition interface for Windows 7, I suspect users would be all over it.
As noted, you’d still need a mouse for more precise work. But the mouse would be an adjunct to the primary user interface, much like pen tablets. Pen tablets have already supplanted mice for certain kinds of precision graphics or CAD work.
Given all those webcams, many of which are capable of facial recognition, I’m surprised this hasn’t become a commercial product yet. With Windows 7 arriving soon, as well as AMD’s Eyefinity, maybe someone will pick this ball up and run with it. I’m waiting, credit card in hand…
