Human Computer Interaction Individual Report Essay

We as a group we puzzle been set tasks to approximate an existing system and capture the need improvements that should be made to the system through comprehensive research utilise the required methods to improve usability of the system. As a group we are to understand the drug user and capture its unavoidably through numerous of method for example, questionnaire.I indoors my group decided to evaluate the system (www.pogo.com) as it was approximation to look the system thoroughly from which some major errors were confronted.To operate if these were to reflect the user of the system and that it was effecting the lack of consistent and comprehensive movement from within the berth i considered to evaluate the system using Shneidermans 8 princely Rules .The paygrade method constructed errors which were found are to be tested with the users and cut feedback via the talk aloud and the questionnaire from which I with my group will be open to test the system and capture the us er requirementsContent Page divide Name Page NumberSummary 1Methods chosen, why 3Problems Encountered 3Feedback from users 4Achievements from the assessment 4Conclusion/ Recommendations 5Bibliography/ references 6Books 6Web sites 6Methods chosen, whyThe interface that chose to evaluate and redesign, was www.pogo.com as this website was not that appealing to me and I think it needs improvements as it is aimed at a family audience.To evaluate the system www.pogo.com it was required to test the system and check if the system had any(prenominal) major error or were they minor problems, in order for me to do this I decided to evaluate the system using the 8 golden rules of Shneidermans.The method was used to evaluate the system as this enabled me to test the colour, resolution, text, lay bring out etc and I thought this method was very useful to advert out the usability problem that the system was carry to the users.To carry out the evaluation I was first to understand the method and then continue to look this with the system (www.pogo.com) .The methods used for capturing user requirements were Observation, Questionnaire and talk aloud. These methods were chosen because they were Easy to agnizek with the system, Cost Effective and Time Effective.Problems EncounteredThe major problems encountered during the task tests were to find the set aside user to tackle these tasks. As the methods used were demanding a wide enjoin of user that fitted in the categories of the novice, intermediate and expert users, it was difficult to address the needs of certain user as all categories were involved and from each users quite a little was taken into consideration.There were novice, intermediate and expert that took the task which was a trustworthy heap for me as this would help me redesign the interface to fulfil the usability needs.Feedback from usersFrom inquire the users to established the tasks more knowledge was gained for what users expected within a website, fr om this I was able to point out the like and dislike. From this I to a fault accept that the users prefer their website to be attractive so it is enjoyable to use and users too like to take minimum sum of money of steps to go off a particular task.The results which I obtained were very useful for redesigning the website. I found out what different usability needs were and what features users wanted to be remained on the website, and any others which they thought required changing.From this information I chose to do a paper ground prototype for my system because it was simple, cheap and provided quick feedback from the user.Achievements from the assessmentHaving completed the assessment I feel that I would be able to explain the usability of any website/interface and from this I am able to identify usability problems such as psychological problems of the system, as well as being able to evaluate any system in depth. From this assessment I have besides knowledge how I would expl ain various methods of capturing user requirements, stating the advantages and disadvantages of the method.Conclusion/ RecommendationsIf I was to do the assessment again, I would use Shneidermans Eight opulent Rules to identify the usability of the system, as I found them very useful both to understand and apply towards the website. I would also use the Ten Heuristics to evaluate the website and I would have a great image of usability in evaluating the system.If abandoned a chance in the future to redesign the system I would choose to do a low fidelity prototype scarcely as well as this I would prefer to redesign the website in a high fidelity prototype provided that I am given up extra time than provided in my first attempt. The reason for this would be that the users would see the prototype in a low fidelity and will be given a chance then to test the system via a high fidelity prototype.As I only had five users to complete the set task, I was unable to get different views fro m users to make changes to the redesign. In the future I would ask more users (maybe 10 different users) to complete at least three different tasks. By doing this, the users would experience more interaction with the system www.pogo.com and would comment more on the results they would achieve from the task, and also whether they were able to complete the task accurately, in a minimum amount of time.Bibliography/ referencesBooksUser and task analysis for interface designBy JoAnn T.
