Human Computer Interaction Essay

The mankind ready reckoner Interaction(HCI) is the field of study of mutual chat between the substance ab procedurer and the estimator. This is the field of fundamental fundamental fundamental interaction is equipped by utilise the put onr porthole which includes the softw ar system as come up as the hardw be too. All the softwargon program which argon organism made argon enabled with drug exploiter embrasure goal and their implementation. Today, Microsoft Windows XP, Microsoft Windows 98 and so forth atomic number 18 the operating systems which atomic number 18 enabled with life identical drug user larboard. This is too the sympathetic ready reckoner interaction.The World Wide weather vane is as good as the ex antiophthalmic factorle of human computer interaction. The field of the human computer interaction is well create today with the barbeling of modern technologies in packet and ironw be both. With the developing in this the field the tend er terms manage menu, alonetons, icons and so forthtera ar introduced which assure the uses and advantages of human computer interaction. (Brad A. Myers March, 1998 pp. 44-54 ) With the development in application of mobiles the human computer interactions atomic number 18 besides increased.The reinvigorated porthole forge wish well touch- assort purpose of computers and mobiles in alike(p) manner has assumption a unsanded direction to HCI. The HCI in future has get around opportunities with the developing parcel program and hardware. 2) Methodologies and work outes for intentioning embrasures the HCI form regularityologies are unquestionable from early systems equivalent treated users cognitive processes to the bare-assed ones kindred web shrewd. The orders for invention the HCI always looks for interaction between the user, computer that is the machine and the conceptioners.substance abuser centered design is likewise the system in which every aspec ts bid requirements, design and so forth are included in which the attention is existence paid on cognitive factors. in this design processes the users use through the hyperlink with a very high-pitched speed. These models as the name de nones are base on the models which are establish on human expectations. The model elicit be integrated by programming and therefore tin be implemented and thence the feedbacks can be underinterpreted for modifications.(HUMAN COMPUTER fundamental interaction p. 1) Paper prototyping is overly a method for intention HCI by developing software. It is apply for examining and scheming user interface. In this method the drawings of the interfaces are created for design. Its is a useful method as the sk and so forthing is faster than the programming. This method can be useful as the persons who do not the programming can also do this. Web design is also a method of designing user interface like web pages, websites etc.using hypertext markup phras e, JAVA as the software toolkits for development of web pages. The web design is use to made websites as graphical user interface(GUI). The web design also implemented to meet the requirement of the website developer as well as the end-user. The web design is based on languages like JAVA, HTML for safety purposes to eliminate the problem like hacking etc. Cognitive method of HCI designing is a earlier method yet still its very constructive.It is based on analysis of two aspects cognitive exchanges with computers like take aiming, reading and other aspect is cognitive stuffing, composition etc. In this process the user analysis is done first off like requirements, taxs etc. This analysis contains the features like memory, perception, requirements etc. The next step is designing and analytical test. This contain the features like language and memory. The last phase is system test to test the authentication of the system.(Douglas J. Gillan & Nancy J. Cooke p. 1) 3) Methods for implementing interfaces at that place are mevery methods of implementing the interfaces like software, interrogation methods, efficient algorithms etc. There are some(prenominal) software tools like windowing systems, toolkits, interface builders etc. These software includes the software like JAVA, Macintosh Toolbox, Visual Basic etc. These software are very safe as they have application in HCI designing as well as in other fields also.The software programming is easy to handle as each person can wee knowledge of it. The methods of implementing interfaces using the software is also good as the monetary value is cut back in designing and the modifications can be made very easily. The software employ has the advantage that if the unused version of software comes in light and the user inadequacy the interface based on this new version. thus the interface can be programmed in the new software and interface can be modified.The libraries can also be used to develop the softwar e. The libraries are used to store the certifyation, execute the programs. Then the programs are implemented which are stored in these libraries. These libraries can be attached to tract the heavy load of data. With the advancement of these libraries the data is now stored in organized and can be shared in any part of the world. The algorithms are also used for HCI designing as these algorithms are created for dictatorial workflow.For detailed representation of the problem which has to be solved has to be studied carefully. This approach is developed by efficient use of the algorithms. 4) Techniques for evaluating and comparing interfaces There are more a(prenominal) techniques for evaluating the interfaces design and utilization. There are some(prenominal) criteria for evaluating like EC directives. There are many issues which have to be undertaken for paygrade of interfaces like controllability, data integrity etc.These factors are mainly used for HCI interfaces evaluati on as these are underlying factors for designing and comparison of interfaces. The HCI interfaces which are being developed essential be user friendly. The techniques which are being used today are EVIDAS II, medicament, KABA etc. These are the latest techniques which are used for comparing the interfaces. These techniques are categorized further as user-oriented like MUSiC and product-oriented like EVADIS II(Chris Stary*, Thomas Riesenecker-Caba, J &-g Flecker, pp1-2).These techniques undertake divers(a) fields like user interface, organization of work, software features etc. These techniques are designed to pass judgment the various factors like appropriateness, management of data, failure of interface chances etc. These techniques has developed the chances of improvement in software quality, user-friendly quality, success rate, cost effectiveness etc. The major task is transparency of software for future modification. These HCI interfaces are applicable to group work, thi s factor is also tested by these techniques.5) Developing new interfaces and interaction techniques The new interfaces which are being designed for the future moldiness(prenominal) includes many features like management and filtering of data, input devices and sensors, learn ability, user satisfaction etc. The increase Reality(AR) design is a latest one. This design is oriented from the Virtual Reality(VR) design. These design are implemented to reduce the cognitive overhead. ( Andreas D? nser, Raphael Grasset, Hartmut Seichter, Mark Billinghurst pp1-5)There are many principles which are being undertaken like affordance, user satisfaction, low physical effort, learn ability, flexibleness etc. There might be a switching from 2D to 3D visualization. The HCI may be designed by touch-screen application. The models which are being designed essential correlate jibe to the need, task, goals of the user. The 2D screen desktop may be given a new look by 3D view. The HCI may be develope d such that they might be connected to mobile and when a e-mail, message etc.come then the user interface attach directly connect with the processor and the communication system and leave alone inform the user directly. One technique may be used by using sensors. When the user wants to switch on the computer or want to give any instruction. Then the sensor which are apply just start their working and copy the order of user. The HCI essential respond to the users instruction quickly. The problem of sulky response must be eliminated in order to make new interface more efficient.The error must be eliminated or must be rock-bottom to a zero level. The interface must have the tracking stability. The user-centered design must be improved to AR designs. The user intervention must be taken into account. 6) Developing descriptive and prophetical models and theories of interaction The models which are to be developed must be based on the many key factors like virtual and augment reali ty, tangible user interface, affective computing, detection interface eye moved based interface , perceptual interface etc.The models are used to design and evaluate the interface technique The graphical user interfaces(GUI) are used today mainly. These interfaces will be modeled according to the needs of the user. The new models will used the basic qualities of the WIMP interface as well as they will work on new innovative techniques like using sensors, 3D surround. The HCI environment must be created such that the communication process must be strong.The metaphoric systems are related to the descriptive models and the those which are related to numerical systems, are towards the predictive models. The predictive models canvas the interface technique with any time-consumption. The descriptive model are different than the predictive models but are used as well like the predictive model. These models does not give the quantitative measure but just provide a scenario to imagine abo ut the situation of the problem or to describe the problem. These models are used for keyboard interfacing, mouse interfacing etc.( I. Scott MacKenzie, pp. 27-54 ) The models which are based on these models are also modified according to the new theories presented like the use of new methods like digital libraries. 7) Conclusion The human computer interaction is very expert today as well as few decades ago when WIMP interfaces were in use. With the advent of new technologies and theories, the new HCI environments has been created and the development in the field of the HCI is going on like 2D to 3D environment on desktop.These all development are due development of new software and techniques which are being used. The latest explore strategies like Ethnography is also beneficial for the HCI development. The web application are being developed with the use of new methods. and so the HCI environment has been developed a lot.References1) Human Computer Interaction, Wikipedia the fr ee encyclopedia.
