[citation][nom]sicom[/nom]Mice are great, but keyboards aren't. I've always thought keyboards could be far more efficient, especially from a gamer's perspective. The existence and success of products like Nostromo seems to point that parts of the industry and consumers agree. Just the prospect of Valve potentially bringing innovation here has me excited![/citation]
As a text input device keyboards are nearly perfect, which is why they have not changed much in the last 5-10 years (and arguably much longer).
For gaming I think that changing the keyboard (like zBoards and other companies have done) is the wrong approach. I think the demand is for something that crosses the dedicated button layout and comfort of a traditional console controller, with the more variable and more accurate move/aim functionality of a mouse.
Keyboards were never meant to be a game interface, they were simply what was available back in the '80s and '90s when PC gaming was the dominant force, and the PC eco system for games like real-time RPGs and FPSs hasn't changed much since then, giving PC gamers huge reflex and control advantages over their console counterparts (and the #1 reason there are so few games that allow cross-platform multiplayer options). This is where newer innovative interfaces (such as leapmotion or kinect2) could run on either platform, and bridge the play-style gap between PC gamers that have cumbersome but more advanced tools, and console gamers who are stuck with controllers which are great for some things, but extremely limiting in other areas.
The problem with all the new hardware interfaces coming out is that they need new GUIs which can handle the multitude of new ways of interacting with technology, information, and software. We may be in an interface hell for the next few years while hardware designers, software engineers, and end users decide what interfaces work best with the most types of workloads. This is only going to get more complicated with the increasing popularity of the multitude of device form-factors available and coming out which range from headless server services, traditional desktops, traditional consoles, new consoles, headsets (ranging from VR systems to augmented reality systems), phones, and tablets. Personally I wish I could skip ahead 10 years to where we have our devices and interfaces figured out again.
