Human–computer interaction

Human–computer interaction
A woman teaching girls in Afghanistan how to use computers. Human use of computers is a major focus of the field of HCI. Because human–computer interaction studies a human and a machine in conjunction, it draws from supporting knowledge on both the machine and the human side. On the machine side, techniques in computer graphics, operating systems, programming languages, and development environments are relevant. On the human side, communication theory, graphic and industrial design disciplines, linguistics, social sciences, cognitive psychology, social psychology, and human factors such as computer user satisfaction are relevant. Engineering and design methods are also relevant. Poorly designed human-machine interfaces can lead to many unexpected problems. HCI Goals[edit] HCI (Human Computer Interaction) aims to improve the interactions between users and computers by making computers more usable and receptive to users' needs.

Outline of human–computer interaction The following outline is provided as an overview of and topical guide to human–computer interaction: What is human–computer interaction?[edit] Human–computer interaction – the intersection of computer science and behavioral sciences, this field involves the study, planning, and design of the interaction between people (users) and computers. Human factors integration Human Factors Integration (HFI) is the process adopted by a number of key industries (notably defence and hazardous industries like oil & gas) in Europe to integrate human factors and ergonomics into the systems engineering process. Although each industry has a slightly different domain the underlying approach is the same. Overview[edit] In essence tries to reconcile the top down nature of system engineering with the iterative nature of a user centred design approach (e.g.

Graphical user interface User interface and interaction design[edit] The graphical user interface is presented (displayed) on the computer screen. It is the result of processed user input and usually the primary interface for human-machine interaction. Page 2 - Fundamentals (of Linux Networking) We’ve discussed the concept of two or more computers communicating over a network, and we’ve discussed the concept of abstracting the low-level concerns of internetworking so that as far as one computer is concerned, the other computer could be located nearby or on the other side of the world. Because every packet contains the address of the source and the destination, the actual physical distance between two network nodes really doesn’t matter, as long as a transmission path can be found between them. Sounds good, but how does one computer find the other? How does one node on the network “call” another node? For communication to occur, each node on the network must have its own address.

Senseg creates textures on perfectly flat touchscreen displays Senseg might have been around since 2008, but the company has now built a prototype of its displays into a tablet. The tactile panel tech uses electrostatic fields to simulate different levels of friction, allowing it to generate the sensation of texture on a totally flat screen. CNET got a chance to try out the display, and said that the textures it creates are easily recognisable — moving from gravel, to packing material, to sandpaper creates distinct, familiar feelings.

Somatosensory system Touch is a crucial means of receiving information. This photo shows tactile markings identifying stairs for visually impaired people. While touch (also called tactile perception) is considered one of the five traditional senses, the impression of touch is formed from several modalities including pressure, skin stretch, vibration and temperature. In medicine, the colloquial term "touch" is usually replaced with "somatic senses" to better reflect the variety of mechanisms involved.

Temporary tattoos could make electronic telepathy and telekinesis possible Close, but no cigar. This goes WAY beyond drones. This is, essentially, the most efficient way to control anything that isn't automated. Just think of this paired with smart contact lenses/glasses. The only thing really holding Google Glass back from its true potential is that it still requires voice and touch controls. If you could instead control your HUD(Heads Up Display) and all of its features with your mind, you would practically be telepathic, messaging people all the way across the globe without either of you even uttering a word. Toshiba brings texture to touch (video) Reach out and touch whatever screen you're reading this on. What if, instead of feeling the glass or plastic beneath your finger, you could experience the texture of a brush, woodgrain, or even a stone? Well, Toshiba's working on just such a project, which operates on the basis of a film affixed to, say, a smartphone's touch panel -- electrical currents are sent through this layer, and your digits are shot up with the simulated sensation of touching those various surfaces. Senseg, the company behind this tech, has been around since 2008, but perhaps this recent prototype demo is a sign that things might actually start going places. It's not like there'll be a shortage of imaginative uses for such precise tactile feedback. Video after the break.

SixthSense - a wearable gestural interface (MIT Media Lab) 'SixthSense' is a wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information. We've evolved over millions of years to sense the world around us. When we encounter something, someone or some place, we use our five natural senses to perceive information about it; that information helps us make decisions and chose the right actions to take. But arguably the most useful information that can help us make the right decision is not naturally perceivable with our five senses, namely the data, information and knowledge that mankind has accumulated about everything and which is increasingly all available online. Although the miniaturization of computing devices allows us to carry computers in our pockets, keeping us continually connected to the digital world, there is no link between our digital devices and our interactions with the physical world. . . . some more pictures are coming soon.
