Week13 Final back-end check & Tradeshow

In this week, we start prepare our Tradeshow, there are some unimportant issues that may influence user experience during the tradeshow, so I need to fix them before tradeshow.

The first issue is that sometimes when we search trove images during the “add dream image” stage, the image didn’t display somehow, but there is an error returned, I’m sure that there nothing wrong with the image URL, so one explanation is we can’t get the Trove image, because the image does not exist in the source anymore, but trove still reference that URL.

 

Error message

We can get the image, but there are some solutions that allow us to avoid this issue, so I add few codes into the “updateURL” function, when the image URL(image_path) is undefined, then add an image name(XXX.jpg) to the database as the image path, then when view the orb, it will display a picture (use same name with XXX.jpg) that reminds us the image not exist anymore.

Another issue is that there are some basic mete data for each images, such as author, date, etc. but not all of images have these data, in order to make sure there are no extra information hide within Trove data, so I add “&Include= all” to the trove API, and the result show us there is no extra data within the Trove data.  

Finally, there is a problem for the show orb function, because another team member doing the front end, and he didn’t fully understand our back end structures, so when he tries to display images, some error occurred, the issue is that we can’t display the orb image normally, so I help him to check the code, and I found out that he was using wrong ordered array to get the image data from database, then I fix it by simply adjust the array value position.

Tradeshow

In this week, we present our final product during the contact sessions. It’s very successful and I’m very enjoy present our works. We set up two laptops, one for user test and another one for play the introduction video, there also four posters to provide visitors with a clear understanding of our application.

Tradeshow setup

In the “dream” team, we were being responsible and all team members were working really hard for this project, I also learned a lot form them and lecture.
