433Mod4SLP Introduction Human computer interaction is an approach through which users can interact with computing devices without understanding anyform of machine language. This facilitates easy accessibility to various applications in the system. In our daily life there are many applications that we witness which is based on such innovative approach.
Discussion
In daily lives I often come across devices that are based on human computer interaction system. It is difficult to perform certain activities without the support of HCI as it creates a unique platform through which humans can interact with devices. A common example of HCI which I experienced is GPS navigation system. This has proved to be beneficial for me as I often plan trips where locating my destination becomes important. The navigation system is a prominent example of human computer interaction approach (Wasson, 2006). My personal experience with this application has been good as it was completely a user friendly technology. I just had to enter my location and my destination and the system was so designed that it gave me the entire route map to reach the destination. The usability factor is a matter of concern as proper interaction would be only possible if users find it easy to operate on such application. Similarly I found the navigation system based on HCI approach possess high usability. When the application was installed in my mobile I was keen towards learning its facilities (Kirlik, 2006). It was designed in such comprehensive manner that before going to the main page the application introduced the user with a live example on how to operate such application. This proved to be helpful for me as I could identify the required steps which I need to take to locate my destination. On the contrary I feel that certain HCI applications are difficult to understand. Like for instance my brother installed a computer gaming software in my laptop and I was not able to operate that properly (Jaimes and Sebe, 2007). It comprised of some complicated instructions which a user cannot understand if he or she does not have some technical knowledge. This in turn I feel reduces the usability of a HCI application.
I have noticed that in some organizations there are user friendly applications implemented in the system but there are certain programs which require some theoretical knowledge. However usability is an important factor when it comes to HCI and its applications. HCI is all about effective communication between machine and human and I think that this can be only possible if technological intricacies are not portrayed in the outer surface. In my practical experiences I have noticed HCI applications are always easy to operate but certain applications such as database design, conferencing, etc., have less usability rate (D. Te’eni and Zhang, 2007). Those applications that deal with basic tasks are easy to use but those which are dealing with some complex job are cumbersome to use.
Conclusion
I think that in our daily lives there are many such applications that are based on HCI approach such as medical devices, educational toys, security systems, home lighting, communication devices, etc. However its usability depends on its alignment towards a particular task.

... The politicization of the literary aesthetic The politicization of the literary aesthetic is a cultural trope that has been tracked by many thinkers in multiple genres. The sort of rhetorical techniques utilized often take these interesting parliamentarian turns, where one party claims the non-existence or ontological instability of an opposing party's "platform" or concern and then when that fails, proceed to monopolize the denotative ground on which the party resides.
