Paper Prototyping
Prototype photos:
The photographs below shows the first iteration of the paper prototype. The prototype aims to test how easy it is to make/receive calls, use and change various location exploration modes, such as navigation in the google earth mode, viewing/posting comments, reading tweets and viewing/adding images.

Briefing:
from Arjun's perspective:
Purpose of application: parents and friends can recreate narratives of the stories their loved ones tell.
- You are a father named Arjun.
- Your son is Raj, a college student at MIT in Cambridge, MA.
- You are to talk to Raj and would really like to visually recreate the stories that Raj tells you.
- You will be using your home desktop computer to talk to Raj.
- You will use a system called Teleport that allows you to visually explore spatial locations as well as look through images and tweets that Raj uploaded.
from Raj's perspective:
Purpose of application: parents and friends can recreate narratives of the stories their loved ones tell.
- You are a son named Raj, studying at MIT.
- Your father is Arjun lives in India.
- You are to talk to Arjun and would really like to communicate your experience of living abroad.
- You will be using your home desktop computer to talk to Arjun.
- You will use a system called Teleport that allows you to store and share your experiences.
Scenario Tasks:
Task 1:
Raj wants to show you where he goes jogging. Accept the call and view the comment that Raj made.
Task 2:
You want to show Arjun Charles River and add a comment.
Task 3:
You want to find out more about Yosemite Park. Check if Raj added pictures or tweets and look through them.
User testing observations (Round 1):
User 1:
Observations
- User ignored panning and altitude controls.
- Navigate icon was mistaken for a button.
- When looking through tweets the user tried clicking on the text to view additional information rather than using the text input box.
- User ignored aggregation panels: map, articles.
Feedback
- Was not obvious how to exit a mode.
- Found the voice transcription natural in the context of application though generally the user does not like it.
- Got irritated with the pop up window.
- Suggested that direct manipulation with a mouse would seem more natural than using the provided controls.
User 2:
Observations
- Likes exploring the interface, testing different navigation controls.
- Had difficulty finding how to move from the image viewing mode to reading tweets mode.
- Does not move directly to address the task but takes extra steps to explore the interface. For instance instead of directly viewing the location, goes to the tweets tab first.
Feedback
- Suggested it would be easier if mode change buttons were located within the main active window, not only from the bar above.
User 3:
Observations
- Confuses navigate symbol for a button (bad internal consistency).
- Likes navigating, using different control buttons.
- No feedback that message has been saved. When adding a comment is concerned if the comment was saved or not.
- Easily finds exit buttons.
Feedback
- Wished there were smoother transitions between high-level and low-level navigation.
For instance, when taking a street view low-level navigation seems more natural. However, our interface provides only high-level mode change controls. - When hitting exit would like to see a confirmation that the comments added have been saved.
- Suggested that dragging with a mouse when exploring the street view would feel more natural than using some of the buttons we provided.
Feedback summary
Inconsistency with expectations:
- Users ignored panning and altitude controls.
- Some description elements mistaken for buttons.
- Modal navigation in top panel not clear.
- Users ignored aggregation panels: map, articles.
- No feedback that message has been saved.
Consistency with expectations:
- Users found it easy to receive and accept calls.
- Took the time to explore locations in the google earth mode.
- Gave positive feedback about being able to interactively view the location, while talking.
