Input Device: Trackball, Touchpad, Pen Tablet, Joystick, Jog Wheel
This page lists different type of input devices.
Mouse
Mouse, the classic input device. Modern ones features laser tracking, and thumb wheel.
Apple's Magic Mouse
Apple Magic Mouse. The entire surface is smooth. No buttons. No scroll wheel. It works by touch sensitivity, like a touch pad. And you can use “gestures”. For example, to left click, tab on the left side with one finger. To scroll, move your finger on the surface up or down. To zoom, touch the surface with two fingers and widen your fingers.
Is this good mouse? No. If you want to impress your friends, yeah. If you want it for industrial use, for example, heavy gaming, long hours in image-editing or editing in 3D Modeling Software, it suck badly. Tire your fingers, rub your skins off.
Apple Magic Trackpad
Every few years, Apple comes out with shiny and novel toys. Actually i don't recommend them. If you are a casual computer user, yeah Apple's input devices look great and work well. If you are in any way using the computer professionally, such as serious gaming, PhotoShop or visual artist, creating 3D Models, or programing (heavy Emacs), Apple's creative input devices are usually less efficient and less ergonomic than the humble homely standard ones.

Drawing Tablet
Now, if you do a lot image editing or drawing, you need a pen tablet, absolutely. This is something i can recommend.
Best Trackball
Jog/Shuttle Control
Hate pressing buttons for sound level control? Get this.
MIDI Controllers
I'm not sure these can be setup or modified so that they actually send keys. If so, they beat the all the rest.
if you know, please leave a comment.
this software “bome software” https://www.bome.com/products/miditranslator/overview, seems to convert midi to key-strokes.
3D Controllers
Many gaming and 3D modeling software can use a specially designed input device. For example, Second Life, Google Earth Mouse Navigation and Keys, Flight Simulator, and other 3D Modeling Software .
