I have always been in search of the perfect input device, and I will not stop before the data jack and mental input are possible. In the meantime, I have to explore other options, which are described below.
Another speedpad, but with more presses per finger: The Azeron Gaming Keypad has an additional "back" and "forward" click per finger, a "side" click for the index finger, secondary "forward" clicks for all fingers, and tertiary "up" clicks for index and middle finger. On the flip side, one row only. Wired, without Linux support.
Price: Around 150 EUR. I do not have this device.
Opinion: If I was still into action gaming, this would be a must-have. There is even a left-mouser version announced.
A bar mounted below your monitor, the Tobii Eye Tracker 5 projects infrared light and tracks the reflection in your eyes even through glasses. Can be used to jump the mouse cursor, but only when pressing a keyboard key. No official Linux support, though, and no multi-monitor support.
Price: Around 220 EUR. I do not have this device.
Opinion: With eye blinks for mouse button presses and without keys to press, I would be intrigued to ditch the mouse. Currently not complete enough for me.
A minimal glove with sensors on all 5 fingers, the Tap Keyboard (or Tap Strap) uses accelerometers to guess which key or mouse movement you mean; some keys require a multi-finger tap. Bluetooth, but no Linux support.
Price: Around 200 EUR. I do not have this device.
Opinion: Multi-finger means not as fast as a normal keyboard, and accelerometer mouse seems poised to be inaccurate. I will pass on this one.
Combining speedpad and mouse, twice, the KeyMouse is a split keyboard where each of the two halves acts as mouse; optionally also as trackball variant. Both bluetooth and wired. And it has Linux support. Sort of an ErgoDox with mousing capabilities.
Price: Around 600 EUR. I do not have this device.
Opinion: Sounds near perfect, though there might be a learning curve for the ortholinear keys, and arrows are only available while pressing a modifier key, switching to a different "layer". However, for that price I will pass for the time being.

For the first time since Razer bought Nostromo, a successor to the N52 has been released, the Orbweaver. But again, no luck for left-handed people.
Price: Around 120 EUR. I do not have this device.
Opinion: I am still happy with my N50. Having more keys seems not so appealing for me. And the no-lefty policy does not make me happy... again.

Wireless mouse becomes pen again seems to be the concept of the Penclic, which provides an alternative hand holding posture for mouse input.
Price: Around 60 EUR. I do not have this device. Can be purchased from the german Amazon store.
Opinion: Seems like a good concept. You can rest your hand, and have a hand grip with better precision that that of a mouse grip. However, the button placement seems to be less than optimal according to the Amazon ratings. Also, the base always moves with the pen, making for a less-than-pen experience. I am pondering to try the device.

Price: About 300 EUR. I do not have this device. As far as I know, you can only purchase them directly from the Emotiv store.
Opinion: I am still in awe of this concept. Unfortunately, it does not seem to have any desktop integration (though a lot of demo apps exist), and it requires saline greasing of the sensors before each use. So it is more for research at the moment.

The Rollermouse Free by Countour Design is a mousing replacement and successor to the RollerMouse Pro. Its "rolling bar of chalk" lies free, making cleaning easier; it is also more wide. Mouse buttons are unchanged below the bar. This time, I am really tempted to buy one.
The good: I tried both a no-name BarMouse (2009-05) and the RollerMouse Free itself (2009-10), and am quite convinced by the concept. It is surprisingly accurate, and I even played a bit strategy games with it.
The bad: Even a rollermouse is not quite as precise as, say, my Razer Diamondback. And it sure is on the expensive side. But it still would be awesome. What breaks it for me is that it never integrates well with the keyboard; typing speed always degrades. I wish there was a good combo, e.g. with a Kinesis Ergo, I would instantly buy it.
From the brain input device department, the Neural Impulse Actuator (NIA) by OCZ is the only actual product on the market as of 2009-05 (unlike e.g. the Emotiv Epoch). It registers both brain waves and facial muscle movements, allowing you to press "mental buttons"; mouse movement is not possible.
Price: About 150 EUR. I do not have this item; they are sold by Amazon in Germany.
Opinion: It's a brain input device! It is not going to get much faster than this. However, calibration and usage seem to be hard or somewhat unreliable, as many users report. And you have to wear the headband the entire time (I even find a bluetooth headset cumbersome).
A novel 3D input device, the Novint Falcon features a ball for the user, which is held by 3 arms and can be moved up/down, left/right and in/out. Force feedback (provided by vibrating the arms) also conveys a sense of texture on the ball.
Price: Not available in Europe as of 2009-05 (international shipping via ebay store); should be around 200 EUR. I do not have this item.
Opinion: Certainly a more convincing 3D feeling than a space mouse. Also, a fully programmable API is open sourced, such that anybody can develop software that works with this device. On the bad side, it does not work out of the box with your software. And I estimate the hand-holding-in-air fatigue as high.
The Celluon Laser Keyboard is essentially a laser projected keyboard layout plus a infrared camera which is tracking where your fingers are. It has a builtin lithium battery and connects via bluetooth to PDA or computer.
Price: About 200 EUR. I do have this keyboard; the getdigital online shop is selling them in Germany.
The good: As expected, the device is very portable, and bluetooth connectivity is reasonably comfortable. Typing with all fingers of both hands is much faster than anything a PDA can offer.
The bad: You need to tap one by one and lift every finger at least 3 mm per keystroke. As there is no tactile feedback, targetting keys is sometimes difficult. Especially holding Shift pressed is prone to failure and sometimes triggers the "menu" button to the left of it. Furthermore, the device works only with PDAs and Windows.
As of 2007, the CL800BT model above has been superseded by the CL850 model.
A new type of mousing, the Rollermouse Pro sits in front of the keyboard and consists of some buttons, a scroll wheel, and the rollerbar. You can roll the bar and slide it to the left and right, which translates into mouse movement; the advantage is that you never need to take the hands away from the keyboard.
Opinion: I can imagine myself using it in a useful way, and the idea of not having to reach for the mouse sounds very good. It is a bit expensive, though. Maybe I will buy one.
The Frogpad is, similar to the Half Keyboard, designed for one-hand input and changes its layout when a certain key is pressed.
Price: About 200 EUR. I dont have this keyboard.
Opinion: Luckily, the device is available for both hands. Personally I find the layout of the half keyboard more plausible, but this is worth a try. There is a also a bluetooth version available.
The Half Keyboard is one half of a keyboard; the other half is activated when you hold the space key down instead of just pressing and releasing it.
Price: About 100 EUR. I dont have this keyboard.
Opinion: I am a left-mouser. This thing is not available for the right hand, which kills it for me. Which is unfortunate, because I believe typing speed could be good when using the mouse at the same time, compared to switching between mouse and keyboard all the time.
The P5 glove from Essential Reality is a glove which records the actions your fingers perform by using a camera (the thing in the background (upper right corner) of the picture). I asked the thinkgeek store about offering them, but they told me they had tried it and think it sucks.
Price: About 100 EUR. I dont have this one.
Opinion: I think I will follow the thinkgeek guys. While the input method may be fast, I guess that fatigue from holding that thing must be high. At the given price, it is extremly unprobable that I would buy one.
As of 2007, Essential Reality seems to have renamed itself to Alliance Distributors.
The Touchstream LP keyboard consists of two "touchpads" - with the crucial difference that the touchpad can track more than one finger; thus, it is possible to gesture. For instance, tapping thumb and middle thinger on the right board and then pulling them together is the Ctrl-X (cut) gesture.
Price: About 300 EUR. I do have this keyboard.
The good: Gesturing is extremely cool. The mouse (also thru gesturing, right hand) is usable; it is, however, more straining than a normal mouse since I have to hover the hand while using. Typing is, while error prone, faster than normal since I have only to tap lightly on the keys.
The bad: Since I cannot feel the keys under my fingers, even after considerable time my error quota is higher than on normal keyboard. Plus, contrary to the opinion on the fingerworks website, it is not feasible to rest the hands on the touchpad; I need the hand again faster than the resting action permits.
Alternatives: Since 2003-08 I also have a iGesture Pad, which is basically the one-pad version, only the mouse plus gesture functions. With it, I am quite content; while the fatigue problem persists, everything else is splendid.
As of 2006, the fingerworks company does not exist anymore, so you cannot buy the TouchStream products.

The N50 speedpad is simply 10 keys, a mousewheel (with stoppers, so it is not "unlimited" in the same sense as the mouse wheel), and a control pad for the thumb.
Price: About 30 EUR. I do have this one. Media Markt sold some 2003-09 in Germany.
The good: You cannot miss your keys anymore. The wheel is useful for acceleration. It can also be used with the right hand (I am left-mouser); the loss of the D-Pad is not too bad.
The bad: The D-Pad is useless. The limited wheel is useless for changing weapons - but hey, thats what your mouse wheel is for. It is slightly to big to be ultra comfortable.
As of 2007, the N50 has been superseded by the N52.
Basically 10 keys, the Claw is the speedpad in hand ergonomic. Notice that the middle finger has the "walk forward" and "walk backward" button intelligently aligned.
Price: About 70 EUR. I dont have this one.
Opinion: It cant be useful for me, as I am left-mouser. And I guess it will be much to big; ergonomic form has the disadvantage of "either your hand fits, or it is useless". I probably wont buy one.

Some specialised input devices make your life better, others not. I hope I have been able to give you a bit of orientation in that wonderful world. Thank you for leaving a part of your attention span here, and have a good day.EOF (Apr:2021)
