Navy Plans To Use Xbox 360 Controllers For New Periscope Systems Aboard Its Submarines (go.com) 121
According to ABC News, the U.S. Navy is planning to use Xbox 360 controllers to operate periscopes aboard its most advanced submarines. High-resolution cameras and large monitors are replacing the traditional rotating periscope in the Navy's Virginia-class subs. While they can be controlled by a helicopter-style stick, the Navy plans to integrate an Xbox controller into the system because they're more familiar to younger sailors and require less training. They are also considerably cheaper. The controller typically costs less than $30 compared to the $38,000 cost of a photonic mast handgrip and imaging control panel. The Xbox controller will be included as part of the integrated imaging system for Virginia-class subs beginning with the future USS Colorado. It is supposed to be commissioned by November.

I have a 25 dollar Logitech joystick. For reasons I'll not go into, it's plugged into something that displays the nominal joystick position on a screen. Once every week or three, I come in to see the joystick sitting dead center but the position display showing it's full-tilt back and to the left because their the joystick, the USB controller it's plugged into, or the kernel module that talks to it hickuped. I nudge the stick with my carefully calibrated index finger and it rehomes itself and the display goes back to normal.
For what I'm doing, it's a nuisance that's to be expected with cheapo toys that use a plastic comb to interrupt an LED and two photodiodes to make an incremental encoder in the two axes. If it's got a million-dollar photonics mast plugged into it, I might spend some time and use multiply-redundant potentiometers with noise-immune readout circuits to give absolute positions. And I'd spend some time and energy doing all the engineering design, and testing, and etc etc to prove that the finished article won't hickup like that for the life of the device. It might cost my customer about 25k per unit to have that level of assurance.

Not redundant sensors, redundant devices. You just throw new controllers at the problem if the old ones fail. These devices are actually shockingly reliable and surprisingly repairable, though.

Actually, even the controller does some of that, but it doesn't necessarily do enough.

I've done optical encoders before, and we had an expensive part that received the signal - could take 4 of them - made by GE.

Reliability and safety. I doubt we want the operator choking on a chord; nor do we want the thing to fail at the wrong moment. Submarines deal with life-and-death situations during wartime - a fraction of a second and you might miss the signs of a torpedo or something else coming at you and now you have a major issue on hand.
So no, "the pull it out, toss it, and put a new one in" isn't a solution when ever second counts.

The sub is a big metal tube. That's not a realistic worry. Also, it's not bluetooth, I've been wrong about that before myself. It's a proprietary RF connection. You can make your own receiver by cannibalizing a 360 for its RF board (they are all over eBay of course) or for about a dollar more you can buy a USB receiver dongle made in China by a third party. That doesn't mean it can't be jammed, if it's not in a shielded environment, of course.

A VR headset would be great if the periscope is actually a ball of cameras pointing in all directions at once, with computers stitching the images together. Then you could just move your head around to look at different stuff.
My guess is that the camera on the periscope looks at one thing at a time, and motors swing it in various directions. So what you need is a control that lets you drive the motors to point the camera. An ideal control would allow for slower and faster running of the motors, perhaps b

Honestly there is enough training, etc going on for the military that whether you use Linux, Windows, Unix, or something else entirely - basic familiarity isn't an issue. You don't just get tossed into the position. Now in a WWI/WWII conflict where you're having to draft massive numbers of people that might be a different issue - but given the state of the US military that's not likely going to be an issue should WWIII come along.

Thumbsticks suck for aiming (Score:5, Interesting)
Not so for the thumbsticks on the XBox-style controller. It doesn't control the direction the camera is pointed. It controls the rate of change of the direction the camera is pointed. You have to push the thumbstick in the direction you want the camera to move, wait for the camera to almost get there, ease up on the thumbstick so the slew rate slows down, ease up some more, ease up some more, then let go when the camera is finally pointed in the desired direction. If you want to rapidly move the camera back and forth between two set directions, it's a lot of work each time, and you need to be watching the camera view to do it.
I emailed one of the developers working on drivers to allow you to use the controller in games which didn't support it, and learned why. The thumbsticks only have 256x256 resolution. That is, there are only 256 discrete measurable directions the stick can be pointing in each axis. This isn't enough resolution for precise aiming, so they have to use the gimpy slew-rate aiming.
For a camera limited to just one degree of motion like it sounds like this one is, you want to use a paddle controller [wikipedia.org]. It's just a potentiometer. You rotate it and the camera rotates along with it. It too has a 1:1 correspondence between direction of the controller and direction of the camera. So you could rapidly move the camera back and forth between two set directions, blindfolded. In particular, if you put a raised ridge on the paddle wheel, the operator can know which direction the camera is pointed by feel, instead of having to read a numerical bearing readout. This is much more intuitive (the operator basically won't need any training) and less prone to error.

You do the validation in software, including eliminating jitter. If the controller appears to be misbehaving you chuck it in the bin and use another one. The Xbox 360 controllers are plenty durable.
