need debugging and modification

• From the testing, we found:
  1. The visibility of Instruction button. Only one user clicked the instruction button for help.
  2. The dark scroll problem. 2 Users can not wait the murder video finished, and tried to click the dark scrolls at the beginning.

3. There is no navigation to back to intro or the beginning of murder video. If user can not understand the story at first time, they have no chance to watch the video again.

4. Technical problems influenced the result. Interesting to find, 3 of them all started form the right slider “Pallas”. However, owing to the technical problems, each timeline video delayed to responded and very slow. Once they can not find the difference on screen, they loose patient to wait and started to try other scrolls, consequently, felt confused the characters.

5. The scroll control not functioned well. 4 Users clicked the arrows or the scrolls as a button. Only 1 user use mouse and control it well. 1 user clicked the screen directly tried to drag and move characters.Issue 6.: Users felt confused about the characters. The classification of each character was not clear enough from long-shot video.

• Modification required:

1. Make Instruction button more visible by size and position. Move the position to the right-bottom corner. Most users started the right-bottom slider, when they got stuck, it’s the most visible position.

2. Remove the dark scrolls at the beginning to avoid distraction. Users will finish watching the murder story without distraction, and then start to play with the movie.

3. Add button of “back to intro” and “back to the beginning” allowing user the chance to navigate anytime.

4. Reassure technical modification on coding and all the possible ending combination of videos can go smoothly.

5. Make the double arrow clickable as a functional button. Users can click both the scrolls and the double arrow icons to make a better control.

6. Clarify the characters in video and in scrolls by different colors, make remarkable connection with scrolls. Considering the video can not be shot again, use After Effects editing software to clarify characters in video. Meantime, put photos on sliders and use flash effects and color coding the scrolls.
