Human computer interaction 

Introduction

The topic being discussed on this particular podcast is on human computer interaction where we will learn on different things about humans and computers. I would therefore urge my listeners to pay attention to the audios.

Difference between auditory icons and ear cons

In this podcast presentation ear cons and auditory icons are used to make the presentation successful. When both ear cons and auditory icons are combined they produce the excellent sound most listeners love. The two are different whatsoever in the extent that ear cons are most preferred by listeners since ear cons respond well to classical commands as compared to auditory icons. In another perspective auditory icons are preferred more by listeners since their subjects link commands with the sound in a good way. Thus it is clearly seen that ear cons are unable to connect the commands with subject as they are relatively slow in learning while auditory icons are good at this since they relate well with the functions they perform( Paterno, Fabio 2010). The rate of errors is more experienced in ear con as it is in auditory icons thus at some extent since the auditory icons are much faster and have reduced rate of errors they are preferred most by listeners.

Why and when audio is helpful

Audio contributes to the human computer interaction process as different research has shown since they portray a good environment than just graphics on the computer. Sound contributes to tasks being made easier and more attractive. Information is better presented by use of sound rather than graphics and messages. For example it is clearly shown that events are much attractive when sound is used in their presentation. Sound is connected by both the function and the button which are being used. Example the telephone is well known to use audio in performing its communication functions. Video games which have a high speed are also known to use audio in their functions. Sound reduces the gap between those people with sight problems and those graphic user interfaces (Polotti, 2008).

Reasons why sound is not a good idea

Sound however effective it is causes problems to many people in the extent that it affects many people in the surrounding environment especially the ones not interested in listening to anything. In addition, through use of headphones and earphones the ears are damaged though this remains the only solution to the problem of sound. Sound remains a big problem and it contributes to environmental pollution for example the noise from cars and loud music contributes greatly to damaging of the ears.

Accessibility and redundancy

Accessibility according to the human computer interaction is generally the capability of different users in regardless of their rate of impairers to use a computer system in the best way possible. It helps anybody use a computer regardless of their condition or disability which includes sight problems as well as ear problems. Redundancy as discussed is the duplication of the same materials and journals with no original background which is obviously unethical (Grechenig & Tscheligi, 1993). Redundancy should be avoided since authors should give analyzed details of their research. The work should be made original and enough evidence provided.

Conclusion

The topic is such a large one but to cut it short, I would say that human computer interaction is well discussed and elaborated. Sound as previously seen is advantageous but on the other hand it causes harm to the surrounding and environment at large. Use of headphones will solve this problem. Also discussed is that everybody has the right to operate a computer system. I would therefore like to thank everybody for taking this time to learn more about human computer interactions and it’s my hope that everybody is grateful for the lessons learnt. Thank you all.
