Project Glass is a research and development program by Google to develop an augmented reality head-mounted display (HMD). The intended purpose of Project Glass products would be the hands free displaying of information currently available to most smartphone users, and allowing for interaction with the Internet via natural language voice commands, in a manner which has been compared to the iPhone feature Siri.
The functionality and physical appearance (minimalist design of the aluminium strip with 2 nose pads) has been compared to the EyeTap (developed by Steve Mann at the University of Toronto), which was also referred to as ‘Glass’ (‘EyeTap Digital Eye Glass’). Though head-worn displays for augmented reality are not a new idea, the project has drawn media attention primarily due to its backing by Google, as well as the prototype, which is smaller and slimmer than previous designs for head-mounted displays.

In human–computer interaction, WIMP stands for ‘windows, icons, menus, pointer.’ denoting a style of interaction using these elements of the user interface. It was coined by Merzouga Wilberts in 1980. Although its usage has fallen out of favor, it is often incorrectly used as an approximate synonym of ‘graphical user interface’ (GUI). Any interface that utilizes graphics can be termed a GUI, and WIMP systems are a derivative of such systems.
However, while all WIMP systems utilize graphics as a key element (namely the Icon and Pointer element) and therefore all WIMPs are GUIs, the reverse is not true – some GUIs are not based in windows, icons, menus and pointers and thus are not WIMPs. For example, most mobile phones utilize icons (graphics represent and result in an action being performed) and some may have menus but very few include a pointer or run their utilities/programs in a window.

In computing post-WIMP comprises work on user interfaces, mostly graphical user interfaces, which attempt to go beyond the paradigm of windows, icons, menus and a pointing device, i.e. WIMP interfaces.The reason WIMP interfaces have become so prevalent since their conception at Xerox PARC is that they are very good at abstracting workspaces, documents, and their actions. Their analogous paradigm to documents as paper sheets or folders makes WIMP interfaces easy to introduce to novice users. Furthermore their basic representations as rectangular regions on a 2D flat screen make them a good fit for system programmers, thus favoring the abundance of commercial widget toolkits in this style.
However WIMP interfaces are not optimal for working with complex tasks such as computer-aided design, working on large amounts of data simultaneously, or interactive games. WIMPs are usually pixel-hungry, so given limited screen real estate they can distract attention from the task at hand. Thus, custom interfaces can better encapsulate workspaces, actions, and objects for specific complex tasks. Applications for which WIMP is not well suited include those requiring continuous input signals, showing 3D models, or simply portraying an interaction for which there is no defined standard widget.

In computing, a natural user interface (NUI) is one that is effectively invisible, or becomes invisible with successive learned interactions, to its users, and is based on nature or natural elements (i.e. physics, also known as Natural Philosophy).
The word natural is used because most computer interfaces use artificial control devices whose operation has to be learned. A NUI relies on a user being able to quickly transition from novice to expert. While the interface requires learning, that learning is eased through design which gives the user the feeling that they are instantly and continuously successful. Thus, ‘natural’ refers to a goal in the user experience – that the interaction comes naturally, while interacting with the technology, and that the interface itself is natural.
