- 3rd version of PP: fixed on table to make it more like a screen + add control on the left side + draw line on right side to align the first scene + change arrows to be “up” and “down”
- 5 scrolls and increased policeman layer: Although in final interface we have only 4 scrolls (we put the policeman in the same timeline with Schmar), for paper prototype we have to separate them to control the policeman individually. In this way, we can avoid if Schmar walks on street and policeman appears in wrong timing then cause our users confusing. The same consideration also applied on the policeman layer.
- color coding characters: for users easy to see different characters movement
- color coding names on films: for “computer” easy to control during test
- change arrows to be “up and down”: in our interface, we planned to put characters photos on the scroll for easy identify each character, so we move the arrows out of the scroll.
Test Process and Participants:
I worked with Michele.
My role is a moderator (observation and asking question) and Michele as both computer and narrator at the same time. The whole process was recorded by camera. We found 7 students in LCC, and asked them general questions to do first-stage investigation because we target at readers instead of a game player. 3 of them were our target audience and interested in participating in our test. We conducted the process by making users see the paper prototype covered by a paper which wrote video on it. The narrator described the intro video and uncovered it to ask users to play with the prototype.
Findings:
1. After the intro video, users didn’t know where to look for help when they get stuck, we have to encourage them to touch the scrolls.
2. After trying our products, though they all understood if they move sliders then the story will play on the screen. They felt confused about which scroll represented which character exactly in the video.
3. One user tried to move the sliders by left and right, instead of turn up and down.
4. Only one user mentioned she can change the story and see different ending. The murder will happen or not happen based on the control of sliders. The other 2 users did not grasp the point of interaction with the story.
5. All of them didn’t know the direction of up and down (sliders) represent different timeline would backward or forward.
Recommendations for our interface.
1. Instruction button is necessary. Add one button on the top-right of the screen and pup-up instructions to help users know how to start to interact with this movie.

2. Give clear hint on the scrolls to guide users find characters: change the position of names from bottom to top and change the order of sliders correspondent with characters’ position in video.
3. Change the direction of scrolls to be left and right, allowing users easier to use mouse control the sliders.
4. Use double arrows similar to DVD player to give timeline hint. Guide users the control function of backward and forward.
