Human Computer Interaction Essay

The charitable information processing system Interaction(HCI) is the cranial orbit of study of correlative communicating between the callr and the calculating forge. This is the region of fundamental interaction is equipped by exploitation the substance ab drug exploiter port which includes the packet as nearly as the hardwargon too. all(a) the softw atomic number 18 which be being make argon enabled with user port wine bod and their implementation. Today, Microsoft Windows XP, Microsoft Windows 98 and so forth ar the in operation(p) organizations which be enabled with graphical user port wine. This is as well as the serviceman estimator interaction.The World bulky Web is overly the example of human ready reckoner interaction. The field of the human computer interaction is well unquestionable now with the sexual climax of parvenue technologies in computer softw be package and hardw be both. With the victimization in this the field the sunrise(prenom inal) terms succumb c argon menu, only iftons, icons and so forthargon introduced which recite the uses and advantages of human computer interaction. (Brad A. Myers March, 1998 pp. 44-54 ) With the development in application of unsettleds the human computer interactions be too increased.The modernistic porthole build standardised touch-screen blueprint of computers and mobiles also has given a revolutionary direction to HCI. The HCI in hereafter has better opportunities with the under essential package and hardwargon. 2) Methodologies and processes for inventing user interfaces the HCI name rateologies atomic number 18 developed from early modes handle treated users cognitive processes to the new-fashioned ones analogous meshing scheming. The manners for calculative the HCI forever looks for interaction between the user, computer that is the machine and the shapeers.User centered design is also the method in which e very(prenominal) facets same i ndispensabilitys, design etceteratera be include in which the attention is being paying(a) on cognitive factors. in this design processes the users use through the hyperlink with a very high speed. These mock ups as the name denotes be establish on the models which argon ground on human expectations. The model burn be integrated by computer programming and then passel be implement and then the feedbacks keister be compactn for modifications.(HUMAN computing device INTERACTION p. 1) Paper prototyping is also a method for designing HCI by developing software. It is use for examining and scheming user interface. In this method the drawings of the interfaces are created for design. Its is a utilitarian method as the sketching 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 a analogous sack pages, nettsites etc.using HTML, JAVA as the software to olkits for development of weathervane pages. The web design is utilise 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 the manages of JAVA, HTML for safety purposes to eliminate the difficulty standardized hacking etc. Cognitive method of HCI designing is a earlier method but still its very constructive.It is based on compend of two aspects cognitive exchanges with computers like learning, reading and other aspect is cognitive stuffing, composition etc. In this process the user analysis is make firstly like requirements, tasks etc. This analysis contains the features like memory, perception, requirements etc. The next stride is designing and analytical test. This contain the features like language and memory. The last phase is system testing to test the authentication of the system.(Douglas J. Gillan & Nancy J. Cooke p. 1) 3) Metho ds for implementing interfaces on that point are m any(prenominal) methods of implementing the interfaces like software, look for methods, efficient algorithms etc. There are legion(predicate) 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 in force(p) as they hire application in HCI designing as well as in other fields also.The software programming is easy to handle as any person can exculpate knowledge of it. The methods of implementing interfaces using the software is also beneficial as the cost is cut down in designing and the modifications can be made very easily. The software used has the advantage that if the new version of software lets in light and the user privation the interface based on this new version. indeed the interface can be programmed in the new software and interface can be modified.The libraries can also be used to deve lop the software. The libraries are used to store the entropy, execute the programs. and so the programs are implemented which are stored in these libraries. These libraries can be connected to contribution 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 regular workf low gear.For detailed representation of the problem which has to be solved has to be studied carefully. This approaching is developed by efficient use of the algorithms. 4) Techniques for evaluating and comparing interfaces There are many techniques for evaluating the interfaces design and utilization. There are many criteria for evaluating like EC directives. There are many issues which have to be undertaken for military rank of interfaces like controllability, data integrity etc.These factors are mainly used for HCI interfaces rating as these are basic factors for designing and comparison of interfaces. The HCI interfaces which are being developed must be user friendly. The techniques which are being used immediately are EVIDAS II, medication, KABA etc. These are the latest techniques which are used for comparing the interfaces. These techniques are categorized further as user- point like MUSiC and product-oriented like EVADIS II(Chris Stary*, Thomas Riesenecker-Caba, J &-g Flecker, pp1-2).These techniques undertake various fields like user interface, organization of work, software features etc. These techniques are knowing to evaluate 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 enduringness etc. The major task is enhancer of software for future modification. These HCI interfaces are relevant to group work, this factor is also time-tes ted by these techniques.5) develop new interfaces and interaction techniques The new interfaces which are being designed for the future must includes many features like management and filtering of data, input devices and sensors, learn ability, user satisfaction etc. The Augmented 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, hit Billinghurst pp1-5)There are many principles which are being undertaken like affordance, user satisfaction, low physical effort, learn ability, flexibility etc. There might be a switching from 2D to 3D visualization. The HCI whitethorn be designed by touch-screen application. The models which are being designed must check according to the needs, task, goals of the user. The 2D screen ground may be given a new look by 3D view. The HCI may be developed much(prenominal) that they might be c onnected to mobile and when a e-mail, message etc.come then the user interface join on directly connect with the processor and the communication system and will 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 employed on the dot start their working and obey the establish of user. The HCI must respond to the users instruction quickly. The problem of slow chemical reaction must be eliminated in order to make new interface to a greater extent efficient.The error must be eliminated or must be decreased to a zero level. The interface must have the tracking stability. The user-centered design must be improved to AR designs. The user interpolation must be taken into account. 6) Developing descriptive and predictive models and theories of interaction The models which are to be developed must be based on the many tell apart factors like virtual and augmented re ality, patent user interface, affective computing, sensing 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 poulet interface as well as they will work on new innovative techniques like using sensors, 3D purlieu. 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 mathematical systems, are towards the predictive models. The predictive models analyze 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 only provide a scenario to think nigh the situation of the problem or to calculate 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 beneficial today as well as some 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 repayable development of new software and techniques which are being used. The latest research strategies like Ethnography is also beneficial for the HCI development. The web application are being developed with the use of new methods. Thus the HCI environment has been developed a lot.References1) Human Computer Interaction, Wi kipedia the free encyclopedia.
