Introduction Research in Human-Computer Interaction (HCI) has been spectacularly successful‚ and has fundamentally changed computing. Just one example is the ubiquitous graphical interface used by Microsoft Windows 95‚ which is based on the Macintosh‚ which is based on work at Xerox PARC‚ which in turn is

A BRIEF HISTORY OF HCI 13.1 Early Interfaces Memex (1945) . Vannevar Bush‚ 1945 [Bush‚ 1945b]. . Memex = “memory extender”. . Hypothetical design (never built) based on microfilm technology and mechanical levers integrated into a large desk. . Vision of document repository with links between documents. . “Trails” = chained sequence of links. . Personal annotations. Memex Chronology . Bush started to formulate Memex ideas in 1932 [Nyce and Kahn‚ 1991‚ page 42]. . Draft sent to FORTUNE

effectiveness of human computer interaction - HCI - can be complex as it involves many influencing factors‚ some of which are determined on an emotional level (making it subjective rather than quantitative). The effectiveness of HCI relates to the usability of a computer system by a human. For a computer to be effective‚ HCI levels must be high. In simple terms‚ a computer that is difficult to use is not a good computer. Indicators of the effectiveness of HCI There are a number of basic indicators

Introduction Augmented reality (AR) is a term for a live direct or indirect view of a physical‚ real-world environment whose elements are augmented by computer-generated sensory input such as sound‚ video‚ graphics or GPS data. It is related to a more general concept called mediated reality‚ in which a view of reality is modified (possibly even diminished rather than augmented) by a computer. As a result‚ the technology functions by enhancing one’s current perception of reality. By contrast‚ virtual

Dear Richman Investments Senior Management‚ It has come to my attention that your corporate security policy for the firm is out of date and that it needs to be updated. In my time here as an intern I have reviewed the security policy and revised it to keep up with all of the technological updates going on in the internet world today. I was assigned this project and being that we have 5000 employees operating in different locations and different parts of the country; I have noticed that some of

Fundamental Principles of HCI Design Introduction I will be describing the principles of HCI and Interface Design‚ giving examples of each of them in use. I will also be talking about perception (including colour‚ luminance‚ Pattern‚ Pop Out Effect and Gestalt Laws)‚ behaviour models (including Predictive Modelling‚ KLM‚ throughput and Fitts Law‚ descriptive modelling (including KAM‚ Buxton’s model and Guiard’s model) and Schneiderman’s 8 Golden Rules. Schneiderman’s 8 Golden Rules Eight

Case Study Kimberly Greenway Liberty University According to the course syllabus we were introduced to the techniques of psychological research. This course was able to provide an understanding of how research is done‚ and what methods we can use to do so. By having a clear understanding of research and techniques used‚ it allows us to communicate effectively in regards to ideas behind the research process. In this paper‚ I will use myself as the case study to examine exactly what I learned

2.2. Multimodal HCI systems The Multi-Modal Human-Computer Interaction will refer to the interaction of the virtual and the physical environment by making use of the natural modes of communication. These modes will involve the 5 human senses and will imply that the multi-model interaction will enable a more free and natural communication. Multi-Modal Human-Computer Interaction will refer to the virtual and physical environment by making use of the natural modes of communication. This will enable

How the effectiveness of HCIs may be measured Quantitative measures of effectiveness Speed The speed at which an interface interacts with the user is fundamental to its effectiveness. If it reacts very slowly to a user then it is likely to be ineffective. Speed can be measured as: • How quickly the user can input a command • The speed at which a user can type in any data • The speed of throughput‚ or the response given by the interface • The length of time necessary for the user to comprehend
