Introduction

Summary We as a group we have been set tasks to evaluate an existing system and capture the required improvements that should be made to the system through comprehensive research using the required methods to improve usability of the system. As a group we are to understand the user and capture its needs through numerous of method for example, questionnaire. We as a group decided to evaluate the system (www.pogo.com) as we did a thorough inspection from which some major errors were confronted by each member. To check 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 site we considered to evaluate the system using the 'Ten heuristic by Jacob Nelsons' and 'Shneiderman's 8 Golden Rules' these were done week 7, 10.1103. Theses were split between the group as two were to evaluate the system using the 'Ten heuristic' and the other two were to use the 8 golden rules. These are stated in the appendences under evaluation methods. The evaluation method constructed within the group the errors that were found are e to tested with the users and get feedback via the talk aloud and the ...read more.

Middle

Also known as concurrent verbal protocol and thought listing, it is predominantly used as a research tool in the field of cognitive psychology. It can be thought of as "self report" or "thinking aloud." This allows a researcher to find out how a person approaches a problem or task and describes the problem solving techniques or interpretations he or she uses. Provides rich, qualitative information about how a person reasons his or her actions in specific situations. Weaknesses of method, the observer may influence or affect how the person doing the "think-aloud" behaves. The need to give a verbal report of their mental process may change how a subject interacts with the task at hand and affect their decision process. A subject can only report what they are aware of and not the underlying unconscious processes that take place in addition to the verbal decision "Talk-aloud protocol is based on the simple idea that to get at someone's thought processes while they solve a problem, you get that person to talk aloud what they are thinking, everything that comes into their head, as they solve a problem. ...read more.

Conclusion

Finally we combine the time measure to our information collecting methods as this allows us to see how long it takes the users to carryout each task and compare novice, intermediate, experts at each task. To identify the main shortcomings of the website Pogo.com and this allows us to use this information to design a prototype that can iron out the mistakes making it more users satisfactory, enjoyable, efficient and effective. Conclusion/ Recommendations As a group we have evaluated an existing system using the ten heuristics to appoint the error that consist within the report. To test if these are affecting the user we used a method like questionnaire, talk aloud observation and time measure to test the system to capture the user requirements. From the user requirement we were able to create a low fidelity prototype which fulfilled the usability of the system. Improvements We as a group think that the prototype could be improved by changing the colours and making the errors much clears and giving a popup error message which would stop the user from enter unless the message is triggered. If we had more time we as a group would have created a high fidelity prototype improving it from the low fidelity prototype. Overall the group has contributed and carried out task well and on time. ...read more.
