Usability Test Phase 3
可用性测试essay代写 The usability test used an experimental research design. Collection and analysis of data were done through direct observation
Methodology
The usability test used an experimental research design. Collection and analysis of data were done through direct observation and experimentations as well as a survey. A structured questionnaire was given to the participants. Descriptive data analysis was used to find the meaning of the data collected. The target population was young people aged 20 years and below in my neighborhood. The samples were randomly selected. The participants were 1 female and 2 males. The tasks of testing the usability of the microwave were assigned to three participants. The experiment took place in a home kitchen with one microwave and was supervised by one observer and one moderator. Each participant undertook the task of tests each at a time.

Discussion and analysis 可用性测试essay代写
All users were able to complete task 1 and 2 but were not able to complete task 3. Task 3 required the users to set the power level of P-50. All participants were not able to know that they had to first set time before setting the power level. Instead, they continuously pressed the power level button, which did not work. One of the participants thought the microwave was not working and opened its door.可用性测试essay代写
Task 1: Set the microwave to cook anything for a time of 3 minutes and 30 seconds
| Time taken in (s) | Steps taken | Difficulty level
1 – Easy 5 – Difficult |
|
| Participant 1 | 1.10 | 2 | 1 |
| Participant 2 | 4.56 | 4 可用性测试essay代写 | 2 |
| Participant 3 | 9.64 | 4 | 2 |
| Average | 5.1 | 3.33 | 1.66 |
Note: The participants could have set time in two ways. The first one was by use of time set function and press 3 and then add 30 seconds button. The second way was a case of appropriation, that is, using the microwave the way it was not intended by the manufacturer.

讨论与分析 可用性测试essay代写
所有用户都能够完成任务 1 和 2，但无法完成任务 3。任务 3 要求用户设置 P-50 的功率级别。 并非所有参与者都知道在设置功率级别之前必须先设置时间。 相反，他们连续按下功率级别按钮，但不起作用。 其中一名参与者认为微波炉不工作并打开了门。
任务 1：将微波炉设置为烹饪任何东西 3 分 30 秒
| Time taken in (s) | Steps taken | Difficulty level
1 – Easy 5 – Difficult |
|
| Participant 1 | 1.10 | 2 | 1 |
| Participant 2 | 4.56 | 4 可用性测试essay代写 | 2 |
| Participant 3 | 9.64 | 4 | 2 |
| Average | 5.1 | 3.33 | 1.66 |
注意：参与者可以通过两种方式设置时间。 第一个是使用时间设置功能，然后按3然后添加30秒按钮。 第二种方式是挪用情况，即以制造商不希望的方式使用微波炉。
Task 2: Pause the microwave in the process of cooking that you already started
| Time taken in (s) | Steps taken | Difficulty level
1 – Easy 5 – Difficult |
|
| Participant 1 | 1.40 | 1 | 1 |
| Participant 2 | 1.55 | 1 可用性测试essay代写 | 1 |
| Participant 3 | 3.53 | 1 | 1 |
| Average | 2.16 | 1 | 1 |
Note: The task of pausing the process in progress was intuitive, and many participants did not find it challenging.

任务 2：在您已经开始的烹饪过程中暂停微波炉 可用性测试essay代写
| Time taken in (s) | Steps taken | Difficulty level
1 – Easy 5 – Difficult |
|
| Participant 1 | 1.40 | 1 | 1 |
| Participant 2 | 1.55 | 1 | 1 |
| Participant 3 | 3.53 | 1 | 1 |
| Average | 2.16 | 1 | 1 |
注意：暂停正在进行的过程的任务很直观，许多参与者并不觉得它具有挑战性。
Task 3: Set the power level at P-50
| Time taken (s) | Steps taken | Difficulty level
1 – Easy 5 – Difficult |
|
| Participant 1 | 24.45 | 7 可用性测试essay代写 | 4 |
| Participant 2 | 22.87 | 8 | 4 |
| Participant 3 | 13.89 | 7 | 5 |
| Average | 20.40 | 7.33 | 4.33 |
Note: Participants were not able to complete the task because they were unable to identify the required steps. They were first needed to set time for cooking then set power levels. All participants were trying to set power by directly pressing the power level button.

任务 3：将功率级别设置为 P-50
| Time taken (s) | Steps taken | Difficulty level
1 – Easy 5 – Difficult |
|
| Participant 1 | 24.45 | 7 | 4 |
| Participant 2 | 22.87 | 8 | 4 |
| Participant 3 | 13.89 | 7 | 5 |
| Average | 20.40 | 7.33 | 4.33 |
注意：参与者无法完成任务，因为他们无法确定所需的步骤。 他们首先需要设置烹饪时间，然后设置功率水平。 所有参与者都试图通过直接按下功率级别按钮来设置功率。
Implication, recommendation and follow-on research
The usability test using a small sample of my neighborhood was enough to indicate that microwave devices require improvement of their user interface design. Task 3 was the most challenging for users. All users took countless time, and steps to complete task 3, and they all gave up. The power level values numeric units confused because food usually has a specific power level from high to medium. Users may not understand which units are high and low. The power level set up for task 3 could be high, medium, or low. Therefore, based on the data, I can recommend that users be allowed to set power levels directly before setting time rather than having to set time first then power level. A further usability survey research can be conducted to find out the usability issues that people face when using a microwave.可用性测试essay代写

启示、建议和后续研究 可用性测试essay代写
使用我附近的小样本进行的可用性测试足以表明微波设备需要改进其用户界面设计。 任务 3 对用户来说最具挑战性。 所有用户花了无数时间和步骤完成任务3，他们都放弃了。 由于食物通常具有从高到中的特定功率级别，因此功率级别值的数字单位令人困惑。 用户可能不明白哪个单位高低。 为任务 3 设置的功率级别可以是高、中或低。 因此，根据数据，我可以建议用户可以在设置时间之前直接设置功率级别，而不必先设置时间然后设置功率级别。 可以进行进一步的可用性调查研究，以找出人们在使用微波炉时面临的可用性问题。
