Trackballs to Brainwaves: The 50 Most Notable PC Peripherals
Miscellaneous
Touchpad – Before 1983

You might think of the touchpad as an input device most commonly associated with the laptop, as the slayer of the trackball and the pointing stick, but they’ve actually been around longer than that. As far back as 1983, Apollo built touchpads into keyboards, as seen in the picture above. Though perhaps doomed to be made obsolete by the touchscreen, the touchpad still holds a place dear to our hearts.
Pointing Stick – 1987

The term “pointing stick” is the generic descriptor for the whole class of rubber doodads that we prefer to call “mouse nubbins.” Known more specifically as TrackPoint, Pointstick, StickPoint, and similar others, these are the little rubber caps found on laptop keyboards that allow you to maneuver the mouse by applying slight directional pressure. Once a dominant mobile input device, the pointing stick has largely been replaced by the touchpad, though some laptop models still offer both.
NoHands Mouse - 1997

There’s no written rule that says a mouse has to be used with hands. The NoHands mouse is a pedal-based controller that lets you control your desktop cursor by moving your feet. You use one foot to rock on a pedal to navigate the pointer, and the other foot is used for left and right clicks. Besides the obvious use of the NoHands mouse for users with carpal tunnel syndrome or other wrist injuries, we know a few people who use foot-operated controllers in addition to hand-driven mice, such as for activating macros in games or even as a hidden boss key.
Wacom Cintiq - 2000

It’s difficult to imagine the graphic design industry without the presence of Wacom tablets. Since 1983, Wacom has been developing and improving graphic tablets that have changed the way artists work with computers. In addition to their pressure-sensitive surfaces and pen digitizers, Wacom also licenses their technology for Tablet PCs. But the most notable Wacom product in recent memory has to be the Cintiq, which combined a computer display with digitizer. The tablet/screen hybrid idea let artists draw directly on the display surface, so they could instantly visualize their work. Since launching the line with 15” Cintiqs in 2000, Wacom has improved its technology work with tablets up to 21”, with a resolution of 1600x1200.
Eye Tracking Technology - 2007

File this under “emerging technologies.” Over the past five years, researchers have been experimenting with various forms of eye-tracking technologies that will let users control their computers with their gaze. In 2006, a Queen’s University study tested gamer satisfaction using an eye-tracking mod for Quake 2 and Neverwinter Nights, reporting that 83 percent of subjects felt an increased level of immersion when using their eyes to replace the mouselook function in game. In 2007, researchers at the Blekinge Institute of Technology repeated the experiment using a mod for Half-Life 2. Once again, players reacted positively to the test. No consumer hardware or software has been announced to take advantage of eye-tracking technologies, but it’s something we’re looking forward to trying out in the future.
OCZ Neural Impulse Actuator – 2008

The OCZ Neural Impulse Actuator, which debuted last year, is the first in what will most likely soon be a crowded market for commercial mind-computer interface devices. In other words: it lets you play games with your mind, by detecting changes in the electrical fields in your brain. The really amazing thing? It actually works—after just a little bit of practice you can run around and shoot your gun by variously thinking, straining, and furrowing your brow. Sure, it’s not good enough to actually win a game yet, but it’s an incredibly promising first step.
3Dconnexion SpacePilot Pro – 2009

If the SpaceOrb is the past of 6DoF controllers, the SpacePilot Pro is its future. Logitech , who folded the SpaceOrb’s makers into its 3DConnexion brand, has fully embraced the potential for 6DoF in 3D design and modeling. With more than 20 buttons, a built-in LCD for controlling program functions and a $400 pricetag the SpacePilot Pro is professional hardware through and through. Still, it’s still hard not to want one, just a little.
