Voice recognition Microphone Immersion method of issuing commands

Speech recognition has a way to go, yet

Another factor to consider with HW interfaces is the ergonomics of the device in question. Ergonomics refers to how the HW fits or blends with the person using it. A more ergonomic piece of HW will in turn be easier and more intuitive for the user to use. An example of this can be seen in the evolution of game controllers; consider the boxy controller of the original Nintendo Entertainment System and the later version found on the Nintendo GameCube, the original could dig into the palms and be uncomfortable after some time spent playing (not that I actually remember that stopping any of us from playing, we just kept boxes of band aids nearby). However, the later controller with the GameCube fits the hand more comfortably and was much easier to use with the layout of the buttons (Figure 10.1).
