Group Members: Me, Sharaz Amin
Chosen Device: Samsung D600 mobile phone
The purpose of the evaluation i will design is to see to what extent the phone is successful in terms of visibility.
‘Visibility-The system should always keep users informed about what is going on, through appropriate feedback within reasonable time’.
The method we will apply for this evaluation is to do quantitative technique call usability engineering. We feel this is an appropriate method for this particular scenario because as it states in the lecture notes it is a ‘powerful tool for evaluating prototypes’. Therefore we can consider the already made phone to be a prototype.
Basically the users will be given instructions to complete two tasks. While doing these tasks they will be observed by us and all results will be noted down. The results will include the time taken to complete each task, the number of errors the user made and any gestures or comments they made which would help the evaluation. There will be 2 users all together. As this is Sharaz’s phone he will be taken as an experienced user and he will undergo the tasks first and i will be observing. Once he has completed the tasks, his times will be compared against a second user who does not own the same model phone. The difference in experience will determine how well the phone is generally usable, more specifically in visibility terms (Nielson Heuristics).
Attributes:
- Visibility of the system status.
Measures and Metrics:
- Time taken to complete each task.
- The number of errors that occur
- User comments
Users (2):
- Sharaz Amin (experienced user)
- Inexperienced user
Tasks for the user:
- Add a new contact with complete details; email, telephone number, name, address.
- Take a picture of the classroom, while zooming in. Then view the picture just taken.
Instructions for the User:
We are carrying out a usability test on the Samsung D500 and we will be grateful if we could just take two minutes of your time and you could complete the simple tasks stated below. After you have completed each task please put the phone down and give us a brief feedback on the task you had just completed. Any comments are welcome.
You can begin each task once we say go and have pressed the start button on the timer, this way we can record your timings.
Task 1) Add a new contact with complete details; email, telephone number, name, address. Make a call to that person.
Tasks 2) Take a picture of the classroom, while zooming in. Then view the picture just taken.
Thank you
