For our user test, we have prototype of our air quality app and bus stop. The app is done by Marvel and bus stop is showed by photoshop. As there is no enough time for us to finish photoshop, so we will just screenshot some pages of bus stop to show the important parts such as information and interaction page. It is just user test so we may still play our app at laptop although it is an phone app. We will do our user test at university library downstairs. We will ask our users some questions about what do they think about air quality firstly or have they used something like this before, then we will show him our app and users can use this app by himself. The main reason for user test is to test what we have done, how it works, does it meet demands of users and so on. The goal of our group is to increase the awareness of public about air quality and pollution and help those who want to know more to understand data more easily. So out “foot” page will be kept focus on and tested as the real-time air quality map is designed for our goal which can also shows the safe area (less-polluted area). From the interview before, we knew that traffic is another big problem both the commuters and buses. Walk should be encouraged so the effectiveness of our foot page may affect people’s willingness to walk and use our app. User responses are really important for our design. About our app, if user do not know how to use our app or he feel confused about why we have this page, we can explain to him and make some improvements.
