The first reading about the future look of interface design misses a lot. I think future interfaces won’t strictly be visual. I think future interfaces could include a plethora of new communication/feedback methods such as bio integration. Humans have always been dealing with user interface design. Arguably you could trace user interface design back to our primitive cavemen ancestors – the ones who made spears and clubs. The way you are meant to hold a club and swing it, the material on the handle, the weight, and the material are all important variables that must be taken under consideration. User experience is all about improving the users relationship/interaction with an object. How do you go about improving interaction? Experimentation with how you interface with something is important. Do you interface with something via touch or sound? Maybe interaction is triggered through brainwaves such as with MindWave EEG sensor. Perhaps interaction is performed via buttons as with a remote. Or maybe it is through simple touch-based gestured as with an iPad. Perhaps interaction is via haptic feedback, such as with the apple watch and maps. The watch taps/vibrates to indicate turn left or turn right. There are thousands of ways interaction can be created between you and an object/device. How do you choose which interaction makes the most sense to the user? There are a bunch of important factors that need to be taken into consideration. For instance, the context of use. It wouldn’t make sense to add all of the features that an iPhone has into the functionality of an apple watch because a watch is inherently tiny, light weight, and something which is constantly worn around the wrist rather than large, usually rectangular, and meant to fit into a pocket or purse. Some other things that matter: Environment of operation, purpose of object, intended user…

In response to the cyberpunk movie,  Strange Days – or at least the trailer, I think they present a great example of how user interfaces can expand beyond the screen. An interface could possibly jack straight into your neural circuitry which could dramatically change the scope of usage.

The point being, user interface design is a diverse subject.
