User Study 3: Paper Prototype

We took our product to the streets!

In order to understand how to characterize the product: what buttons to use, where to place them, etc., we decided to test the product on people.

The test was done at the IDC, because we knew that most students are opinionated and that we can learn learn a lot from any opinion they may give us.

The test was very successful! We were glad to hear that people like the idea and are waiting to use it in real life, and more were glad that we learned a lot about the interaction of users with the product.

Here is a short video of the test:

Below are some questions that arose from watching the interactions:

* Is it right to decide that the amount of time a user is interacting with the system affects the level of the weight of his voice? If so, we should think about making it in a way that the use would intuitively understand.  At the beginning of the interaction, it should show that the amount of time they are going to invest in has a direct effect on their vote.

RFID tag -
As mentioned, the tag is supposed to signal that the user started his route to the front page, and help us to measure the amount of time they used the system, as a way to indicate the amount of time they had invested in learning about the issue, and thus calculate the weight of their vote. The idea is that a user who has taken more time to learn about the issue, listen to pubic opinion, and record their thoughts knows more about the issue, and so should have their vote count more.

Examination revealed a number of advantages and disadvantages in the existence of the RFID tag.

Many respondents indicated that this tag would go with them from voting ballot, and will be part of their keychain, thus creating a sense of commitment and a community between people to whom expressing their opinion on their surroundings is important. The tag may cause an emotional connection.

Some suggested that the tag will be used for things other than voting, for example, instead of plain tags, they will contain personal information, like resident identification.

Some respondents felt the chip very redundant in the interaction.
We realized that the tag requires the presence of a stewardess/machine in order to give the tag to people who had not received it elsewhere. Because this process requires a registration system, it may be cumbersome.

Buttons -
We noted that, without exception, users intuitively thought that the screed was a touchscreen. 

The fact that the screen is untouchable (because the screen is inside a glass "wrapper"), incurs a significant drawback. It seems that people are so used to touch screens, and we realized that maybe we should think about changing the form to one that contains touch interaction.

Disregarding that fact, here are the conclusions regarding the different buttons:

Informative Screen: 
A green triangle-PLAY, which everyone understood intuitively

Opinion Screen:
- No need for up/down arrows, just right, left and enter.

- Middle button - don't make it a square.  Some said that square reminds them of STOP, maybe do a green triangle in the middle of the screen as a piece of paper and right and left arrows << >>.

- In the future, this screen will not be in a loop. The two options, record yourself and view opinions, should have segments that correspond to the weight of that part of the process.  For example, if recording the opinion is more important, it should have a larger space.

- Some of the subjects felt it was important to see their recording before deciding to have everyone be able to see it.

- When watching public opinions, many subjects thought it would be helpful to know some personal information about the speaker, such as age.

Voting Screen:
- It is not clear yet how to vote - if we decide to go with the RFID tag, we need to make sure that there is a way to intuitively understand that it should be used as a voting tool.

- Are red and green for and against confusing for the user.  They could be confused with the PLAY and RECORD buttons.

In the end we learned a lot from the paper prototype, and still have many issues to solve in regards to the interaction.
