Download file to see previous pages The development and innovation in computer systems, may it be software or hardware, requires constant usability testing and interface modifications. This technique is used to evaluate a product by testing it on users. This is inarguably an irreplaceable testing practice since it gives direct input on how users use the system (Nielsen, J.,1994). These modifications need to take place constantly thorough the development cycle of particular software or hardware. Various methods can be employed in order to test and evaluate a particular computer interface in development.

The user-based method, as the name implies, takes real users as a testing medium. This method yields the most reliable and valid results as it directly analysis the feedback from the user. In this technique, a group of users is provided with the test interface in a defined environment or out in the field. The interaction with the interface is closely observed with emphasis on how they use that particular software or hardware to complete their task. Speed is also one of the primary gauges. After the task is complete, users are then interviewed and are asked to describe their own experience and perception of the interface. Thus, using this data and feedback, the interface can be further improved which will eventually improve the satisfaction level of the user. The user-based evaluation procedure is usually video recorded and analyzed later. However, this evaluation can also be in the form of a joint interaction between the user, the evaluator, and the interface under evaluation. This enables the evaluator to get more hands-on feedback from the user.

Ideally, a large group of users would provide more concrete feedback, but this is not always logistically possible. As a result, there is considerable interest among HCI professionals in how to get the best feedback from the smallest focus group. ...Download file to see next pages Read More

... and expansions once the interface has been released for the user. Another problem that new applications face is that of compatibility. As developments in computer technology is happening at lightening speed, sometimes the compatibility of an application with a particular hardware becomes an issue. A problem may also arise if the application is not thoroughly evaluated before release. This could result in user finding problems working with that particular interface and may ultimately result in user dissatisfaction. CONCLUSION Human-Computer Interaction is practically the intersection of various significant fields. Where computer science merges with behavioral science and technology design to create better computer systems and applications...

...Human-Computer Interaction... Violent Video Games Introduction Video games portraying violent content have become exceedingly popular especially among youths. Research studies show that their effects could be positively associated with the violent video game and frequency of play. Effects of Violent Video Games Meta-analytic research reviews have revealed a number of negative, cognitive, behavioral and affective outcomes of exposure to violent video games in both physical and developmental aspects. A decrease in academic achievement could be associated with increases in time spent on violent video games. Repeated violent video game playing leads to more aggressive behaviors. They also become less responsive to real life violence due to decrea...

...of venues. One major area of work in the field focuses on the design of computer systems. The goal is to produce software and hardware that is useful, usable, and aesthetically pleasing. A closely aligned area is the evaluation of systems in use. This is related to design, because to know if a design is useful or usable requires observing it in use. However, this also extends to the study of the larger social consequences of use. Increasingly, evaluation takes place at multiple levels of analysis: the individual, the group, the organization, and the industry or societal sector. (The Psychology of Human-Computer Interaction.
