Poster and flyer
To effectively communicate our idea we chose to include the robot arm, projection illustration and some short copy in the poster. This ensures that viewers are able to gain an understanding of what our project is if they have not seen our 12 minute presentation on the night. We wanted it to be informative and not too abstract. This will be an A1 sized poster so the text is large enough to read.
We managed to make some adjustments to the flyer as the previous draft was too vague. We nailed down our concept into 3 points. The copy below those points described the project in a bit more detail much like what we had on the poster. We also updated the contact information for each group member on the back of the flyer.
Cup detection
Thanks to Rob, the code for detecting our cups have been improved to remove almost all outside colours. As our cups are almost a pure red colour, it was possible to remove all other channels of colour and focus only on the cups through the use of Processing’s in-built image functions. As such, the cups are able to be detected without as much jitter as before.
Usability testing
We were able to recruit five participants for our usability testing. We tested our menu and quiz web app to make sure the user journey made sense and users to have a clear understanding of the interface. The web app was loaded on an iPad mini and run on Safari. We were unfortunately unable to test the interaction with a projection of our sketch, as the required projectors have not been set up.
Evaluation tasks:
1. Ordering a drink
Users were asked to order a drink through the menu. They all performed the task without difficulty.
2. Answer quiz
Users were then asked to answer the questionnaire that obtains their interests. They understood what the questionnaire was for when we asked them. Users were confused what cup number they had to input during the process. We had to direct them to enter a random number as we did not have the full experience of the interaction yet. Users clearly understood the written instructions on the web app shown at the end of the questionnaire.
What we found and what to improve on:
Menu web app
The item graphics were quite large when the user scrolled through the selections. The graphics will need to be reduced at a smaller size so users do not accidentally tap on it while scrolling.
Quiz web app
Originally, the questionnaire had confused some initial users whether they were progressing through the quiz, as all three questions had a similar layout and there was little feedback between the questions other than the dots on under the speech bubble. We quickly rectified this by extending Mr. Bear’s neck a bit between each question as a sort of progress bar. After the addition, the new participants were able to progress through the questions without much confusion.
One participant requested to have more questions available during the quiz. In an ideal situation, we intended to include more questions but was forced to limit it down to 3 due to the large amount of processing power required to run the sketch.
We hope to eliminate the confusion that came across in the cup number step when we have the projectors set up in another usability testing session. All cups will have a number stuck on it so users will know what to do with it.
Hardware
Our final setup utilizes two long throw projectors and a camera situated above the bar table. The camera, used for tracking the cups on the table, will be mounted at an approximate height of 2 metres to have an entire view of the table. There are 2 projectors setup so that the maximum size of the projection covers half of the table. In conjunction with this setup, we’re using a program called Resolume Arena to split the projection between these 2 projectors to make one complete sketch.
Promotional video
We went for a documentary style for our video to fit in what our concept, process and inspiration were. We have also provided subtitles for the video so viewers will be able to read voiceovers if they are unable to hear it at the exhibition. The Youtube transcript is provided (click on CC to view the subtitles) so far but we are considering to add hardsubs to be displayed at the show. This is so that we can add our own flair of style for the entire video.
